Re: [Elecraft] stereo channel output balance
I've had a distinct channel imbalance problem developing slowly, I suspect, for about a year or more on my K3. I discovered very recently that it is being caused, or substantially worsened at least, by the AFX audio effects function. I am almost entirely using CW through headphones, listening to just the main receiver with the subRX off about 50% of the time and the rest listening to pileups. With the AFX on, there is a marked bias towards my left ear. With AFX off, the audio is more or less central. I've messed around with the AFX delay setting but it doesn't seem to make much difference: at all settings, the marked left bias exists. I haven't put it on a scope or soundcard meter yet. [I occasionally have another audio problem with what sounds like a high tone intermod product caused by over-driving something in the audio chain. If so, it seems to be ahead of the volume knob since that makes no difference. The problem is intermittent - lasts for a week or two then goes away for months, and is annoying but not bad enough to ruin the receiver. I don't know if it is related.] Any ideas what's going on? 73 Gary ZL2iFB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of todd ruby Sent: Saturday, 22 March 2014 11:38 a.m. To: Elecraft Reflector Reflector Subject: [Elecraft] stereo channel output balance Is there any way to control the balance on the output coming from the spkr output jack on the back panel?

Re: [Elecraft] Portable antnennas
How about making a homebrew multiband vertical for $not very much at all, one that will literally fit in your pocket? Use a steel tape measure as the vertical radiator, with the body of the measure lofted into the sky using a very low tech bit of string hanging over the branch of a tree. Run out a few radials on the ground beneath, and feed with a short run of coax to your Elecraft exciter. Pull or slacken the string to adjust the length and get it to resonate and radiate on whichever band you are using (you may be lucky if the body of the measure is heavy enough to reel itself down when you release the string, but a safer method uses a complete loop of string over the support, attached to the tape measure body, so you can pull it either way). A 10m tape measure will do for 7MHz and up, provided you can find a sky hook at least 10m up (palm trees in the tropics are about 15m high, I guess). If your tape is only 8m long (most are, here in NZ), simply add an extension - a couple of metres of wire on the free end of the tape - and connect that to your coax. For 80m, if you have a 20m sky hook, you can extend the radiator by adding another 10m of wire on the bottom end, or simply use the length of wire as an inverted-L over whatever skyhook you can muster, the higher the better. Spring steel is not an ideal conductor but it's good enough, especially as you will have /P and perhaps an exotic prefix for gain! I think of this as the poor man's Steppir vertical. If the aforementioned palm tree is dangling over the sea on a tropical island, your $negligible investment will amaze you. There's a paper describing a slightly more sophisticated version on the web - Google Fat Max antenna (Fat Max being the brand name of the tape measure he used). 73 Gary ZL2iFB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of Mark Tellez Sent: Monday, January 13, 2014 13:14 To: Elecraft@mailman.qth.net Subject: [Elecraft] Portable antnennas Hello all, I would like to get some advice - based on experience - regarding the various portable antenna options there are currently available on the market.

Hi Bryan.

Re: [Elecraft] K3 -Advice: how to configure APF for least ringing
I use APF only as a last resort, Robert. It can sometimes help me dig out and record very weak 10m beacons under QRM from adjacent beacons, with CW filters on turbo, sometimes also using the manual notch filter to try to kill the worst QRM. It takes time to peak the desired signal precisely on the nose of the APF, using the fine tuning setting, the CWT function and watching audio levels with the audio recording software (Audacity in my case). Beacons transmit continuously so there is no mad rush to get it set up. For regular DX QSOs, it's not worth the bother in my opinion, but as I recall the APF facility was introduced in response to requests from 160m DXers desperate to glean the faintest sniff of RF from the ionosphere. It does indeed ring. There is probably a physics lecturer desperate to tell us that ringing is an inevitable consequence of the very tight filtering, plus artifacts from the digital processing I guess. Ringing gets worse with fast CW but beacons tend to send quite slowly. 73 Gary ZL2iFB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of Robert G Strickland Sent: Saturday, 11 May 2013 11:46 a.m. To: Elecraft Subject: [Elecraft] K3 -Advice: how to configure APF for least ringing As a 98% cw operator, I've explored the various K3 weak signal features.

Re: [Elecraft] K3 - Eric Co.... Please relocate the Link/UnLink button.
My name's Gary and I'm a DXer. I can't recall accidentally LINKing VFOs for a good year or more, not since I started using macros to drop into and out of split mode, set up the audio and filters etc. Couldn't the issue of DXpeditioners accidentally LINKing VFOs, or perhaps tuning the wrong VFO or nudging the knob, be solved simply by them locking their transmit VFO? FWIW I vote to fix other longstanding firmware bugs rather than fiddle with LINK, e.g.: - The CW/PTT sequencing glitch that sometimes screws up my CW if I release the PTT while still sending; - CW-in-SSB function producing no output but appearing to key the K3, sometimes (QSK+ related if I recall correctly); - The power surge that happens if I trigger the previous bug, then change to CW mode and hit the key (this one trips the KPA500 alarm and makes me say ouch!)

I understand what you're saying, Rich, and it makes sense, but personally I use N1MM's CQ repeat function instead of the K3's.

If it's an easy firmware change, I'd be happy to see the K3 denote repeat mode in a different way, although there are only so many ways given the LCD segments and LEDs available.

Re: [Elecraft] K3: SP 2 switches back to SP 1 during RX in Split
I've had something similar. The cause on my K3 (SN 2887) appears to be some sort of intermittent problem in the current-sensing circuit. The K3 presumably detects excess current, assumes it is the stereo audio chip being shorted by a mono speaker (it isn't!), and switches itself to mono to protect the chip. Watch the K3's current meter: at times, mine varies wildly between 1 and N amps where N is 'several', on receive, doing nothing much at all. Right now, my K3 is reading a stable 1.10 amps. The last time this issue happened to me was about 6 months ago. The actual current draw from the supply was stable but the K3's meter was kicking around, occasionally tripping the protection circuit. It cleared up by itself for no obvious reason. I've had it a couple of times before that too.

[Elecraft] K3: Unstable current voltage on RX
Hi guys. Any idea what would be causing the K3's built-in ammeter to constantly fluctuate around 1-3A, and the voltmeter to constantly fluctuate between 13.3 and 14.0V on receive? I occasionally notice HI CURR warnings, and the rig resets itself from SPKRS=2 to SPKRS=1. The PSU itself is fine - stable at 13.77V (measured at the PSU end) on receive, dropping to 13.13V when transmitting a 100W carrier. While checking the readings for this email I noticed that the ammeter stabilized at 1.07A for about a minute after I've transmitted at 100W for a few seconds, before going back to the 1-4A fluctuations. I wonder if this might be related to the PA pin corrosion problems reported on some K3s? Mine is S/N 2887. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KPA500 Issues
Hi Kent. It could be an RFI issue but it could also be a faulty connection somewhere that won't pass enough current for high power. Do the KPS's SWR LEDs light up like a Christmas tree when you operate barefoot at about 100W with the KPA in standby? If so, you clearly have a problem with your antenna or feed. With the KPA in operate mode, watch those SWR LEDs as you gradually increase the drive from 5 to 25W: if it seems OK at the low end but suddenly flashes the oranges/reds and faults out, I'd suspect a dodgy connector, most likely one outside that has corroded or loosened. 73 Gary ZL2iFB K2 K3 KPA500 W2 Mojo PS You can search the archives for lots more through Nabble e.g. http://elecraft.365791.n2.nabble.com/template/NamlServlet.jtp?macro=search_p agenode=365791query=kpa+swr -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of Kent Tiburski Sent: Sunday, 10 June 2012 1:33 p.m. To: elecraft@mailman.qth.net Subject: [Elecraft] KPA500 Issues Hi, I have a KPA500 amp and have some issues with it.

Re: [Elecraft] KPA500 Assembly Question
Hi Dave. I can't say for sure but the original screws for the plate were a fraction too long, causing pops when the PA heated up due to thermal expansion. Some of us simply filed a fraction off the original screws to seat the plate more tightly, and that solved out problem.In other words, slightly short screws are better. 4-to-5 threads sounds to me like it ought to work OK, so I'd settle for that ... but like you I'd be a bit concerned about the inventory of parts, just in case those screws are destined to be used elsewhere.

[Elecraft] RQRE: K3: CW in SSB mode broken?
I concur Frank. I have QRQ turned on 'permanently' and use QSK a lot, which I guess could be the reason CW-in-SSB is mostly broken for me (and you I guess) but not for everyone. I just checked as you suggested: in sequence ... 1. I had been using CW on 30m. Changing the rig to SSB mode and hitting the paddle gave the sidetone and triggered the PTT line but produced no RF out i.e. CW-in-SSB was broken. 2. Power-cycling the rig made no difference. It's still broken. 3. Turning QRQ off in the menu made no difference. It's still broken. 4. Power cycling the rig (with QRQ still configured off) restored CW-in-SSB. It works! I fixed it! 5. Turning QRQ back on made no difference. It still works! 6. Power cycling the rig (this time with QRQ configured on) broke it again. So it seems I can reliably break and fix CW-in-SSB depending on whether QRQ is on or off then I power-cycle the rig ... BUT ... there is ALSO some dependency with the band and mode the rig is in when it is power cycled. On 6m, power cycling the rig with QRQ on does not break CW-in-SSB. On 10m, power cycling the rig with QRQ on DOES break CW-in-SSB. Power cycling with QRQ off fixes it. On 12m, power cycling the rig with QRQ on DOES break CW-in-SSB. Power cycling with QRQ off partially fixed it i.e. the first dit gave power out but then it broke. On 15m, same as 10m. On 17m, same as 10m. On 20m, same as 10m. On 30m, same as 10m. On 40m, same as 10m. On 80m, same as 10m. On 160m, same as 10m. Those results on both 6m and 12m are interesting. The 6m result is repeatable (which means *provided* I *always* remember to QSY to 6m before I switch off the K3 at night, CW-in-SSB will still work in the morning!) but I cannot reproduce that 12m result where it sent just one dit before breaking. How odd! Now 12m behaves like 10m. I though I would also check whether it matters how I turn QRQ on/off. All the testing above was done using the CW QRQ option on the menu to toggle it, but in CW mode with QRQ configured ON, QRQ can also be toggled on/off by hitting RIT or XIT. Now I discovered that on 30m, power cycling with QRQ on while the rig is in CW mode does NOT break CW-in-SSB, but power cycling with the rig while it is in SSB mode DOES break CW-in-SSB. So again, *provided* I *always* remember to turn the to rig to CW (or I suspect any mode other than SSB - it's fine in data mode, I haven't tested the others) before I switch off the K3 at night, it looks like CW-in-SSB will still work in the morning! Yet another finding: I can toggle QRQ off/on/off/on repeatedly using the RIT/XIT button in CW mode. But if I power cycle the rig while QRQ is configured on but toggled off with RIT/XIT (let's call that QRQ suspended), it will no longer toggle back on with RIT/XIT after the K3 restarts. In other words, the rig 'forgets' that it was in the QRQ suspended mode. The rig does 'remember' the setting of RIT/XIT after a power cycle but the RIT/XIT frequency offset is cancelled back to 0. 73 Gary ZL2iFB -Original Message- From: Frank R.

Re: [Elecraft] Any need for the handle?
You can tell that your K3's handle has the Elecraft Mojo Core if it has a slight curve in it, due to being hand-carried through airports and ports to some exotic DX QTH, where the Core gets downloaded over the air from other Elecrafties in the pileups, using the Elecraft Mojo Transfer Protocol (EMTP). Even if you only operate at home, provided you work enough exotic DX with your Elecraft gear, the Core will eventually accumulate in the handle from all the pileups and DX QSOs and gradually a gentle curve will set in. If your K3 has a flat handle, you are evidently not working enough DX. Taking the rig to somewhere such as Wake Island or Peter I will speed up the mojo transfer and the curvature process dramatically. 73 Gary ZL2iFB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of iain macdonnell - N6ML Sent: Tuesday, 7 February 2012 10:01 a.m. To: Bill Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Any need for the handle?

Re: [Elecraft] [W2] Waterproofing the sensor
Hi David. I haven't waterproofed the sensor head but I did experiment with a ~30m long Ethernet cable to see whether I could locate a second sensor at my remote antenna switch plus the one near the rig, to check the feeder loss. It didn't work out. Looking at the schematics, I think there are resistors in the lines inside the sensor box that might be worth bypassing to see if I can get enough signal back for a realistic reading, but I ran out of play time before being able to try that. 73 Gary ZL2iFB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft- boun...@mailman.qth.net] On Behalf Of David Ferrington, M0XDF Sent: Saturday, 28 January 2012 4:28 a.m. To: elecraft@mailman.qth.net Subject: [Elecraft] [W2] Waterproofing the sensor Reposting this since I haven't seen a reply, which is unusual for this list.

(It was on at the same time as CQ WW SSB) As we were just 2 of 5 operators in the club station (VK4WAT) we decided to lock down our K3's so that the yaecomwood drivers would be able to use the K3's. Each K3 was locked down so that it was a single band radio, mine on 40M and Gary's on 20M. That's when we noticed the possible problem. You can lock out all but one band in firmware but the radio will still change bands! On my radio, I had all bands but 40M locked out, yet it could still be changed to (And it was fully operational on) 20M and 80M even though those bands were locked out. The behaviour on 20M is noted in brackets. Try the following: Config: Band Map Turn off all bands but 40M. (20M) Exit Config menu: From 40M band. (20M) Press Band UP Rig changes to 80M. (40M) Press Band Up again. Rig changes back to 40M (20M) From 40M band: Press Band Down Rig changes to 20M. (15M) Press Band Down again Rig changes back to 40M (20M) Note that at no time does the rig change to one of the so called WARC bands in these 2 tests. However, if the test is done with the rig only having 30M enabled, then shifts to 5MHz and 17M occur. As my rig has the 2M internal transverter I have also tried that band with the following results: 2M band enabled, all others locked out. BND UP selects 10M BND DWN selects 80M The behaviour is similar on all bands when only one band is enabled. In each rig we also tried with 2 bands unlocked and each rig performed as it should with all bands but the 2 selected for operation being locked out and unable to be used. So it appears that this issue occurs only when all but one band is locked out. This has been checked on both my K3 (Serial #4257) and Gary VK4FD's K3 (Serial #679) with the same results. Gary's firmware revision at the time was v 4.25, mine was v 4.30 and although I now have 4.31 in the rig it still does this behaviour. I'd like others to try the same procedure to see if the same results are found and then we can get Wayne to checkout the firmware. Over to you all.

Re: [Elecraft] K3
I have to send my new K3 to the Elecraft Dr. Since its assembled (100 wt and sub receiver not installed yet)and no box, I'm thinking of generous amount of bubble wrap box then in another box with peanuts. Generous bubblewrap in a decently strong box, well taped up, is *probably* enough by itself Larry, so the extra outer box with peanuts or more bubblewrap will make sure it's OK, and postal insurance will be sure to be sure. Just in case of a disaster in the sorting office that somehow separates radio from boxes, make sure the radio itself can be traced back to you - perhaps sellotape your QSL card to the under side? 73 Gary ZL2iFB PS My Elecraft goodies always arrive in ZL immaculately, boxed and wrapped and presented. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] W2 SWR alarm
Hi. I finally figured out how to set, adjust the level and reset/clear the SWR alarm on my new W2 wattmeter. I had been trying to command the W2 to change the alarm setpoint simply by sending a [ or ] from the command tester in the W2 utility, but inputting [ or ] followed by enter always returned [44; each time. I re-read the command reference (which, by the way Elecraft, is about as obscure and geeky as it could conceivably be!) thinking I was sending the wrong command, but apparently not. Next, I tried putting the [ command in a macro, and that did the trick: each time I send the [, the W2 reduces the set point, and ] increases the set point. Curiously the [ and ] now work whether I use the macro or directly enter the commands. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KPA500 - just 500 watts?
Many countries have lower limits ... 400W in G, VK, and ZL, I think Almost right, Fred. We Kiwis have the luxury of a whole dB more, or 500W out in old money, but since it's measured at the transmitter output rather than measured or calculated at the antenna feed point (as in the UK), some of us max out well below 500W of radiated RF even with a legal-limit amp. As a long time member of the G-QRP-Club, I'm currently enjoying WSPRing to Europe on 40m with 1W out of the K3 giving roughly ½W into the vertical and a very slightly warm long run of coax. Admittedly I'd be bored stiff if it wasn't fully automatic, so I leave it running while I Do Other Stuff, working or sleeping in fact. The KPA500 sounds ideal for me *provided* it is as reliable as, errr, oh, death and taxes. Amp reliability is every bit as important as size and weight for DXpeditioning and contesting. 72 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 - Observations during NAQP CW
Yes, my experience is that 200 Hz is MUCH too narrow when running. I normally use 350 or 400 Hz DSP with the 400 Hz roofer. So long as the band is not totally chockablock with wall-to-wall sigs, I quite often listen across 2.7kHz width on CW and occasionally I hear people calling me towards the outer edges. Mostly, though, the wide bandwidth allows me to keep an ear on the QRM on either side of me and perhaps to shift my TX frequency to take advantage of the gaps. It takes practice to be comfortable listening in such wide bandwidths, picking individual sigs out by concentrating on their tone, speed, timing and keying characteristics, but it saves a lot of fiddling around with the RIT or split knobs. That said, when things get real tough or I get tired, I'm very glad of the ability to shift the upper or lower limits independently, the very nice narrow roofing filters and amazing non-ringing DSP good down to less than 50Hz bandwidth. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 CW bug-ettes

[Elecraft] K3 CW bug-ettes
Hi! I've noticed some weeny bugs - or rather things that don't seem quite right to me - in K3 firmware v4.03, DVR v1.03: 1. The new QRQ QSK mode works nicely aside from the known limitation of no RIT. However, this limitation still seems to apply when I change from full break in to semi break in using the band/QSK button. I have to go into the menu and de-select the QRQ option as well to get RIT back. 2. When in SSB mode, I can send CW just by hitting the paddle but if I assert the PTT first (e.g. using my footswitch), the rig goes into TX but won't key. 3. In SSB mode, if I accidentally hit the DVR voice-box message replay button twice, or if it bounces, the second replay interrupts the first but there is an extended silent delay at the end after playing the message, before the rig drops back to receive. [In CW mode, the second press chains another message as expected, but there is no extended hang at the end.] These are so minor, they hardly qualify as bugs. Just quirks really. Features if you will. 73 Gary ZL2iFB K3 #2887 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 CW bug-ettes
The QRQ option works in semi-QSK mode as well. It allows you (or some machine!) to send clean code at higher speeds. I've noticed that without the QRQ option -- even in semi-QSK mode -- when the speed gets above about 35 wpm it starts to have timing issues. After about 45, it is really bad. ?? I'm surprised to hear that, Vic. I thought the QRQ+ thing was all about making the TX-RX changeovers as slick as possible for QSK, so I don't know how it would affect semi-break-in since the rig is mostly held in TX. I seldom send above about 32 or 34wpm though, so perhaps there's some issue at the high end that I just haven't noticed yet? 73, Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Balun Questions
1:1 baluns are dead easy to make: simply wind a few turns of the antenna end of your coax feeder around a suitable toroid core before connecting it to your balanced antenna. I use the FT241 cores from Amidon Associates, the k type for 160-40m bands or 61 mix for the higher HF bands. I can easily get 10 turns of RG58 coax on a core, and these seem to work nicely for me [I don't have the knowledge, test gear or patience to test them on the bench, but depend on Mr Sevick's advice in his book.] I've had no problems running our legal limit of 500W into these. 4:1 baluns require a just bit more work. These are made by winding a bifilar coil using two tightly-strapped wires of the appropriate size and type on a suitable core - a chunky T400A2 powdered iron core in my QRO balun (capable of well over the legal limit I'm sure), with an SO239 connector for the coax. All my baluns use watertight plastic boxes with rubber gaskets to seal their lids, stainless-steel hardware for the antenna connections (S/S wing nuts make them much easier to connect up antennas in the field), and some care to ensure they remain watertight in use (e.g. I use superglue to wick into the gaps and seal both SO239s and antenna connections to the case, plus self-amalgamating rubber tape on any PL259-SO239 connections with a layer of ordinary electrical tape over the outside to cut down UV damage to the rubber). For LF dipoles that will put a lot of stress on the center connections, I use an army-surplus ceramic open wire feeder spreader for strain relief on the antenna wire, using tie-wraps to hold the spreader to the box through the box corner mounting holes which don't penetrate the sealed section, at least in the boxes I can buy here. Even buying everything new and importing the cores from the US, they are *much* cheaper than any commercial units of similar power-handling capacity that I can obtain, here in ZL anyway. As a very happy customer, I have no hesitation in recommending Amidon www.AmidonCorp.com There are photos etc. on my site at http://www.g4ifb.com/html/homebrew.html#Baluns and I'd be happy to answer any queries as best I can. 73, Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] FW: OT Carrying radios on commercial flight
I quite recently flew to Europe from California, and back, with a KX1 and an HT and Buddipole (in suitcase). I put a copy of the QRP Quarterly in my backpack, as it has a big ad for the KX1 in it, but they didn't look. Five of us flew to 9L for CQ WW CW last year, hand-carrying three K3s (mine in an aluminium camera bag/flight case, the others in laptop type bags or ordinary carry-on bags), two Alpha amps (with the HT transformers separated to avoid hernias), three switchmode PSUs, 5 laptops and assorted poles in skibags, plus various wires and hand tools to make up a competitive M/2 station on the roof of an hotel in Freetown. We were all impressed that if and when the gear was checked by airport security, we explained what it was and what we were doing and were allowed on our way, whether travelling together as a group from G to 9L or individually from US, A6 and ZL to G. We carried our amateur license papers but I don't think we were asked for them. We didn't take any SLA batteries. That said, we had a fabulous local helper in 9L and there were some duties to pay when leaving 9L - a few dollars cash and lots of smiling seemed to do the trick :-) A couple of years earlier, I took a 2m HT as hand baggage on a trip from G to ZL but, at the refuelling stop in A9, someone spotted it and insisted that it was packed separately and handed to the pilot for the onward journey. If placing an HT or KX1 or K2 with internal battery in hold baggage, I would suggest separating the battery from the radio and protecting the battery terminals to avoid shorting and fire, or else inserting a plastic spacer between radio and battery, to avoid it accidentally transmitting in flight. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] OT: The use QRP
You might choose not to answer, but the station signing /QRP is breaking no laws. Dead right Tom. I will work (almost) anyone who calls me, and do my level best to log exactly what they send me as their callsign (plus or minus sending errors, receiving errors and typoos of course - we are only human). I don't have the time or inclination to check out every foreign administration's callsign rules before logging someone: I figure it is THEIR responsibility, not mine, to use a legally valid callsign with permission to operate on whatever band, mode and time they are on. I do however like to double check when someone sends me a weird call, just in case they or I busted it. The calls used by foreign ops in BY still puzzle me because they use two full callsigns separated by a slash. But, the point made by our Swedish friend tells me that *some* hams would deliberately avoid answering me if I ever signed ZL2iFB/QRP - something I don't do, by the way, but the point is generally valid. Personally, I *like* to know when the guy on the far end is running QRP or a wet string antenna or whatever. It tells me my receiving setup is working nicely, and usually means he is a homebrewer with a great big smile having worked ZL with his flea-power. I *do* try to give priority to QRPers and other weak callers in pileups, and sometimes deliberately ignore the really loud callers, especially those who insist on calling all over QSOs in progress and expect to shout their way into my log. QRPers generally aren't that rude and frankly, out of necessity, they are often better operators. QRPers happily persist until I have their complete call accurately logged, whereas some others either ignore or don't notice me sending their calls incorrectly, or give up after just one or two repeats when I am clearly struggling to make them out. My ears prick up if I catch /QRP in a pileup and I'll go the extra mile to complete the QSO and make someone's day. I appreciate that some don't share my appreciation of QRP, nor should they. I'm not trying to force my will on anyone. This hobby is broad enough for us all. So, if you do want to tell me you are QRP, by all means add /QRP to your call or tell me what you're running.

[Elecraft] K3 PTT dropouts on CW
I often use a footswitch to hold the PTT closed during an over, mostly to stop my clunky old amplifier dropping out until the end of the over. However if I release the PTT footswith while still sending CW (relying on the rig's VOX to continue holding the PTT), the K3 drops part of the morse character being sent and blanks the sub-VFO display briefly. Can anyone else replicate this? [If you don't have a footswitch, I guess the microphone PTT or front panel XMIT button will have the same effect.] It only seems to happen if I release the PTT at the very instant the rig is sending: if I'm careful, I can release the PTT in between characters with no ill effects. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Contesting with logging software on a PC (not MAC)
One thing I would recommend is to run your log/db on a USB flash based device, this way if your PC decides to act up or even worse the drive dies then your log will be safe. Errr, not if the flash drive dies, unless you meant to use the flash as a backup. With no moving parts, flash drives are probably more reliable than conventional hard drives but they are not immortal and are only rated for so many read/write operations. Also *all* your local drives of whatever type may go up in flames if the PC or shack catches fire, or someone may steal the lot There are also a few other technologies other then the flash drive approach, you can get a free 2GB account from http://www.dropbox.com and point your log to your dropbox folder and it will backup into the ether in real-time and you can even have the same dropbox folder on a backup PC ready to go. That's the better option - an offsite backup - if used as a backup, in other words again not the only copy. The online file systems are fine if you have a sufficiently fast and reliable Internet connection, but again I would advise sending backups off-site and retaining one or more local copies of your log as well, just in case the organization running the offsite system has a technical fault, or deletes the files, or whatever (trust me: it happens). You can also take occasional offline log backups onto CD-ROM, or yet another flash drive, that you physically remove from the machine and place elsewhere in safe storage, far enough away from the shack not to be caught in the same fire/burglary/whatever. If that's all too much effort, at least consider uploading your log regularly to Logbook of the World. LoTW is a 'last resort' backup since it only stores the minimal amount of info on each QSO, but at least it is possible to retrieve the basic QSO data if you have no other choice. This has a useful side effect of increasing usage of LoTW! 73 Gary ZL2iFB PS This applies equally to Macs and PCs. And PDAs. Even paper logbooks are both valuable and flammable! __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Contesting with logging software on a PC (not MAC)
No actually I meant use the flash for the actual live log. Flash based drives are far more reliable then traditional platters. True, probably. Flash has a life expectancy for ~10K read/writes far less then what would be used in a 24hr contest :) Is that so? I have had many platter drives fail in my career and as of to date never had a flash device fail (knocking on wood). Me too, Lee, but the key point remains: if you only have a single copy of your log on one device, you're putting a lot of faith in that one device. Mechanical reliability of the device is not the only concern. I am also a huge believer in off-site backups as well, we are seeing newer technologies like dropbox where it acts more like a local drive then a backup device. I use that service to create corporate wide shared folders across large geographical locations and its been very reliable. Agreed! I don't want to wander off topic here, but John was specific about contesting scenarios and I think we have him covered :) Yes but other forumites might have interepreted it in a more general sense. If between us we help someone avoid losing their entire log, I think we've done a good deed! Also, does LOTW allow for restoring your log? I thought they once frowned upon that at one time. I don't know about them but yes you can retrieve your whole log, or rather the data they have retained from the log you submitted to LoTW. There are hints on how to do this in at least 5 different ways on my website, if anyone needs it: http://www.g4ifb.com/html/lotw.html#UsingLoTW 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3_CW_Data_Mode
A while back, I made a suggestion to Wayne that perhaps the TX inhibit pin on the ACC port could be given another purpose - to invoke TUNE. I envisaged a new config setting like CONFIG:TX INH = HI=Tun or LO=Tun. Wayne seemed to think it wasn't a bad idea, but would be very low priority, based on demand. It seems like this model may work for the Quadra application too, without having researched it at all. While repurposing the TX Inh pin has appear for non-Quadra users, it is a step backward Sounds to me like an inadvisable combination of controls sharing the one line: TX inhibit and key TX clearly are opposites. If someone accidentally misconfigures their K3 (not altogether unlikely), this could get messy if a TX inhibit command actually keys the rig. I'm not arguing against the facility to tune the rig if that's what you really need, just not on the TX inhibit line. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] [K3] Diversity and CW?
Does CW benefit from diversity reception? Can anyone relate any experiences with such improvement and some details on their setup including filters/settings? Absolutely Jim! Diversity helps on ALL MODES. The main thing I notice is that it fills in the dips, in other words when a signal fades in QSB on the main antenna, it seems to not dip as far and may even come up a little on the diversity receiver. The net effect is that the signal appears to drifts side-to-side from ear-to-ear rather than up-and-down into the noise. I estimate diversity is worth a few very valuable dB on receive. It helps most with those weak, QSB-ridden DX signals wandering up and down at the band noise level. Nothing special needed on the filters settings - just turn diversity on - with one exception: for best performance, the main and diversity RXs need matched filters. Mismatch will apparently cause a slow 'beat' and reduce the benefit. The more important issue is to have sufficiently different antennas for main RX and diversity RX, ideally with both spatial and polarization diversity. I have been using my normal TX antennas for the main RX, all about 100m from the shack on a remote switch, and a single 30m wire loop for diversity RX, about 10m from the shack in the opposite direction. The 30m loop works best on 30m, of course, but helps to some extent on all other bands except 20m where it's too badly mismatched. A full set of monoband diversity RX antennas would be lovely, and I guess a decent multiband vertical would work OK too, but meanwhile the 30m loop does the job ... Or rather it did until a storm broke the line, and I put up a 12m TX loop instead! I miss diversity and plan to reinstate the 30m loop, moving the 12m loop across to the TX end. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3: Carry-on Pelican 1510
If I am going to carry the radio onto the plane again, I would get a case that's not so heavy - it only has to be protected from the other passengers cases, and no bouncing around in flight. I used a shiny alumin[i]um flight case meant for transporting camera and electronics gear, from a local shop. It is 18x13x6 externally. The pluck-out high density foam inside is a fairly tight squeeze for the K3, so it is snug and well supported. Small light enough for hand baggage, and strong enough to risk being put in the hold if the airline people at the gate ever insist it can't go on board. Try your local electronics or camera shops. Much cheaper than a Pelican too. I was surprised to have no problems with it at the airport security scanners travelling from ZL to G to 9L and back, though I did have my amateur license in my carry-on backpack just in case they were curious. Also suits the K2 (instead of, not as well as the K3!), leaving space for Palm paddle, antenna wire, switchmode PSU etc. See my K2 suitcase set at: http://www.g4ifb.com/html/elecraft_k2_k3.html#K2 73 Gary ZL2iFB K3 #2887 K2 #1770 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 needs survey -- firmware and application software
In what must surely be the latest evidence of my brain's declining function, I constantly confound the V-M and M-V buttons, inadvertently writing over the memory contents. Pressing the V-M button while it is locked would produce an audible beep and the text message unlock V-M Nice idea Brian, a kind of senior interlock. Meanwhile, I've taken the very simple but surprisingly effective measure of colouring the V-M button red with a marker pen. I now think twice before pressing it. Usually. I've also managed to delete the contents of a memory accidentally, more than once, by trying to escape from the memory entry mode having ignored the red. Hitting the CLR button doesn't just cancel the memory entry mode, it clears the memory, as it is supposed to do according to the manual. Maybe the K3 should require a double-press or hold of the CLR button to clear a memory? 73 merry Christmas all, Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 Instant-split macro
Hi all. I'm having fun configuring my instant-split function, and an undo, to my personal liking, feeding off ideas from others on this reflector and trying them out via the K3 Utility. It works well but the really cool part is that we can each have our own settings without pestering the Elecrafty wizzards to death, or voting, or waging flame wars here to define the perfect split function by committee. Fabulous! Would it be possible for us to replace the standard SPLIT function (accessible by a long hold on AB) with our own custom split function, please? The command to enter split mode within the macro would of course still need to call the default split function not re-start the macro (!), but this way we would not need to remember which macro key we had reassigned for split as it is conveniently already labelled. 73 Gary ZL2iFB K3#2887 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 Split reminder
There is just so much any manufacturer can do to protect an operator from him or herself. The K3 already has the delta f light, the SPLIT indicator on the display (TU W2ZK - I'd forgotten that) and frequency readout for both VFOs. As one who has made his share of errors with the K3 and other radios, there is simply no substitute for just learning how to use any radio. True, and it seems I'm still learning! I like the arrangement on the TS850 and similar radios which have a set of TX and RX buttons for VFO A and VFO B, with LED indicators for the active VFO. Visually, it's easy to select the split. The K3's smaller display and control panel make this harder, but not impossible. I'm just retraining my eyes to spot the new clues. Maybe turning up the LED brightness will help (Menu - LED BRT) but I support the idea of making the delta-F LED flash in true split mode (not just with RIT/XIT). I usually get it wrong having excitedly QSYd to a spot frequency on DXcluster: the rig defaults to no-split, naturally. I normally remember to tweak VFO B up 1 (or whatever) and set the sub-RX to listen there, but sometimes I neglect to hit-and-hold the split button as well. That's quite a lot of buttons to press in a hurry. So FWIW I also vote for an instant split function, i.e. if I hold the split button, I'd like VFO B to shift up/down by a configurable and ideally mode- and maybe even band-dependent offset from VFO A and also turn on the sub RX [if fitted] on VFO B. [Yes, this would of course be an optional, configurable, take-it-or-leave-it change to suit those of you who don't like *my* defaults!] In the absense of a firmware fix for this, maybe someone can figure out a way to make the logging program send the relevant commands to the K3 from one button press, or just whenever I click a cluster spot (since most spottees are operating split)? The real problem with split errors is the insidious nastiness of the cops when a quick RSE up will do (and the DX isn't TX!), or perhaps a Talk cluster message that no one else sees. Either would be far less disruptive. Absolutely. See http://www.k6sgh.com/splitpolice.htm :-) 4U1UN on 30m was wiped out by an EA caller this morning, who I think was calling another lower station on split. The cops who sent UP UP UP UP IDIOT etc., several times each, made a simple problem worse since the EA was evidently not listening on his TX freq (another good reason for the instant-split function to also set the sub-RX on VFO B). 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

1-4 and 5-8 respectively. Mind you, it's easy to re-record any

Re: [Elecraft] [K3] Will I Lose the 120 Watt Max If I updateTheSoftware?
Most 3-500 based amplifiers with 2800 V (no load) on the plates require 120 Watts or so for legal limit output. That's about 11 dB gain. Even with 3 x 3-500s in my LK550 and 2,900V no load, I only need about 25-40W input depending on band to reach our legal limit: 500W. Which is plenty, way too much in fact for the digital modes. Part 97.317(a)(2) limits the maximum gain to 15 dB (approximately 50 W drive for 1500 W out). Not in NZ. Is there really a max gain regulation in the US? How quaint! The extra 10 to 20 watts of drive makes a difference for those who have SB-220, TL-922, AL-82, AL-1300, AL-572, etc. amplifiers. It can mean another 200+ W output. ... The difference will be small in pure signal strength terms but sure the operator's confidence is improved. A cheaper option (as used by certain CBers) is to tweak your power meter to read high. Seriously, though, a bit more attention to operating skills and maybe a little investment in your antennas and feeders will eclipse the QRO option every time. #1 DXing tip is simply to be very active and listen hard. #2 is to save up those tenths of dBs you get for free by eliminating unnecessary coax connectors, and indeed unnecessary coax. Someone should start giving out 0.1dB savings stamps and a DXers' collector's card. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 - Quantizing...
Hi Tony. As a very active CW op, I would find what Wayne has just mentioned a backward step. Quite often I find occasion to ask DX to move up 1 when they call me as I finish a QSO I had initiated by responding to a CQ - in other words - I need to move my intending QSO away from the other stations' frequency. It's really handy to be able to go up 1 or 2 etc exactly. Rounding off the next KHz would totally defeat the purpose for me; or am I missing or misinterpreting something here? As I recall, the TS850 only quantized (rounded off) the frequencies when using the rapid QSY function (i.e. the M.CH/VFO.CH knob). QSYing with the VFO knob or RIT/XIT stepped as normal in whatever step rates it was set to with no rounding. Quantizing was useful to get quickly to rounded frequencies, such as the NCDXF beacons on 28.200 21.150 etc. Also for rapid band changes when chasing mults in contests (QSY 7035 NOW). By the way, I'm sure that the Kenwood rig could be told whether or not to quantize with its' equivalent up 1 button as I would call it. Maybe a config setting - I can't remember. But the K3 function will presumably be a configurable option too so those who want to quantize can and those who don't needn't. Actually an up 1 split function (e.g. if A=B, then SPLIT would automatically add +1 kHz on B since there's no point in 'splitting' on the same freq) would be neat for us CW DXers - maybe an up X button where X is a settable parameter would suit the SSBers too? 73 Gary ZL2iFB ZM4G G4iFB (www.G4iFB.com) K3#2887 K2#1770 Forget the Internet.

I can switch modes and it remains. Removing the antenna does not stop it, actually makes it a little stronger with the noise level dropped. I'm using firmware 3.30 beta. I tried on the SUB receiver and I hear nothing. Hi Jim. I have a fairly weak birdie there (well v close), a solid carrier not 12 WPM CW. Can hear it on the subRX as well. Were you using the NR I wonder? It can sometimes make stuff sound like it's comin n goin. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Band changing/mode changing
But . In the heat of switching back and forth you must be VERY careful to use the VM button - do not miss and use the VM button because you will end up losing one of the memories and have two memories the same. There is no safeguard on VM . That is supposedly on the list to have a double tap of the VM before it writes to the memory location, but there are too many other things ahead of it, I guess. I've coloured my VM button with a red marker pen. Far fewer finger fumbles fankfully. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] K3 sudden power loss
Hi all. Yesterday afternoon my K3 #2887 was merrily transmitting 33% at 5W on 17m for WSPRnet as normal when by chance I noticed the external wattmeter was showing no power out on transmit - none at all, not a squeak. The internal wattmeter is also showing no power out, aside from the first bar permanently lit in TX. The receivers still seem to be working fine. The rig was working OK up to then and has been since mid-April. I wasn't fiddling with any of the settings at the point it packed up, but before anyone asks here are the ten checks I've done so far: 1. I tried sending CW and SSB - neither works. Nor does TUNE, at any power setting. Nor does any other band. 2. I tried using VOX on both semi and full break-in, and PTT - no joy there either. The TX LED lights as expected but no watts escape. 3. I've plugged a 100W dummy load directly into the ANT2 socket, selected ANT2 and tried transmitting, just in case there's some cable or antenna problem. Nope, that's not it. 4. The K3 is not in TEST mode (the TX light is on continous not flashing). I cycled TEST mode on and back off to be real sure. 5. I checked CONFIG: TX INH is off, and again cycled it through the other settings to be sure to be sure. Nope, not that. 6. I tried running the TX gain configuration through K3 Utility: the front panel shows ERR TXG and the K3 Utility reports: Unexpected response DS@@°À; to DS; State 153 Calibration power settled at 0.0 W .; There be gremlins. 7. According to the internal metering, the K3's voltage is reading a steady 13.5V and the current sits at about 1.28A on RX, increasing to about 1.62A when I hit the PTT. No change from that level when I key the paddle or speak into the mike, whether whispering, shouting or swearing. I even tried coaxing it to life, complementing it on the colour of its LCD ... 8. The power setting makes no difference: I've tried from 0 to 100W. I hear the PA relay engage around 12W as normal, and the internal power meter changes between high and low settings as expected. It's just taunting me. 9. The 20A circuit breaker on the PA is in - not that I'd have thought it would prevent the QRP level working at least. 10. I've reloaded *all* the firmware: I was using the latest beta 3.25. Reloaded that, no change. Reloaded an older version 2.78, still no change. What should I try next? I guess I need to pop the lid, look for smoke emitters and poke around at the TX driver and PA stages plus the antenna change over relay and ATU area with a multimeter but havent figured out exactly where to poke yet, nor what I should expect to see on the meter when I do ... I have other radios here and a scope. I guess I could try to trace the TX signal with the K3 set to QRP, fishing around with a wire tail on another radio's antenna socket or the scope input ... Maybe ... What do you think? 73 Gary :-( ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Off-Topic - Straight-key speed cpontrol -- Ergonomics
I think maintaining a loose linkage in the wrist, elbow and shoulder really helps to relax. I like to fidgit around a bit while sending CW; can't do that with my arm glued to the table. YMMV, of course! Whatever works best for you. I recently bought a Natural keyboard from Microsoft which has an angled split down the middle so the left and right hands are less inclined to intertwine themselves around the middle letters. As I get used to it, it's gradually helping me improve my touch typing. It's sold on the benefits for sufferers of Repetitive Strain Injury (= typists elbow = glass arm). Of a little more relevance, it came with an oversized mouse with a high thumb groove and operating instructions that tell me to lay the right side of my hand on the table next to the mouse, then rotate my hand until the thumb reaches the groove, *leaving the side of my hand still resting on the table*. Like the keyboard, it felt a little odd at first but I'm getting used to to it ... And now I'm starting to wonder about tilting my Bencher paddle in a similar way. I can easily make a little wooden wedge to lift the left paddle relative to the right, but a total redesign of the paddle to suit my hand's natural resting position will probably work better than the original paddle design which sits parallel to the desk. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K2 Tuning knob resistance to tight
Back then others reported great success replacing the felt washer with a leather washer cut from an old belt or other scrap leather piece. No fuzz and they said it provided great friction control. Since the K3 uses similar felt washers for both VFOs, is it worth us making this change now, even before we get the fuzzies, Ron? 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 Audio Level
I have mentioned in the past that I have noticed, fairly frequently, that sometimes when first powering up my K3 the received audio sounds weak. This evening I was listening to a 20M QSO between an LU and an LA, both S9. I had the distinct notion that for the af gain setting the audio was not as loud as I would normally expect. Hi Mike. My K3 is left on most of the time so I haven't noticed it at startup ... But I did notice sporadic significant reductions in the audio level on 30m the other evening. At first I thought it was someone tuning-up zero-beat on my frequency and triggering the AGC, but it wasn't that. Next I thought there might be an intermittent antenna connection but the SWR was fine and the coax cables in the shack, at least, are all fine. I've had a similar problem in the past with a sticky antenna change over relay in the amplifier (sometimes on going to receive the RF level is way down because the relay hasn't properly closed - a quick tap on the PTT usually fixes it, temporarily), but on this occastion the S meter level looked normal. So I'm foxed. I haven't noticed it since. If it happens again I'll take more notice of what's happening and might even record it. 73 Gary ZL2iFB PS The end literally dropped off my K3's AF knob yesterday as I touched it - the knob appears to be crumbling like dry fruitcake. It hasn't been knocked or abused, just used normally. Elecraft kindly already sent me a set of replacement knobs due to the outer ring/knobs cracking over month ago so now I really must make time to fit them! __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Magnetic Loops
I'd like to be clear when I wrote earlier that a small transmitting loop is very inefficient. And I'd like to emphasise that this thread is about physically small magnetic loops, not fullsize quad or delta type loops which are efficient radiators with relatively high radiation resistance, in my experience. I have used fullwave wire loops on 80, 40 and 30m for both TX and RX with great success. By the way, I don't know if it's the same with magnetic loops but the fullwave loops radiate mostly broadside to the plane of the loop. If the loop is vertically oriented (e.g hanging between two trees), the polarization of the signal is determined by whether the loop is fed at a horizontal or vertical section of wire. If the entire loop is laid 'flat on its back', most of the radiation heats the ground, some heats the clouds but I'm uncertain what polarization the signal would be - probably horizontal I guess since all the wire is parallel to the ground but I may be wrong. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 160M Diversity Users
I am about to order filters for the K3 and need some final advice. Hi Mike. I have a pair of 400Hz and a pair of 250Hz 8 poles in my K3. I'm pretty active, 99% CW, and rarely use the 400Hz (maybe once a day) and very rarely the 250Hz (once a week). The DSP works extremely well. So of these, I'd recommend the 400Hz, and save up for the 250's later if you decide you need even narrower bandwidth than the 400+DSP can achieve. The 8 poles probably have a better shape factor than the 5 poles, judging by my experience comparing the 5 pole stock Kenwood filters with the 8 pole IRC replacements in my old TS850. With the DSP, I'm not sure you'd notice the difference but as you see I went for the better filters and don't regret it. On extremely rare occasions (e.g. fishing out CW callers in SSB QRM from Indonesian pirates) I have wound the filters right down to the minimum 50Hz and even at that ridiculously narrow setting, the K3 is a joy to copy with no appreciable ringing - miles better than the TS850 and indeed any other rig I've tried. I also use diversity with a 30m fullwave loop. Works great! I'm thinking of getting the AM and/or FM filters next so I can open up the bandwidth to listen to a whole chunk of band at once using an AF spectrum program: it sometimes helps to listen to all the callers in a pileup and to choose a clear slot to call. 73, Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 Diversity Rocks!
Just how much of an improvement do you find with diversity reception? Is it possible to quantize? Hi Doug. I'm not (yet) on topband but reckon that diversity is worth a few dbs (up to maybe 5 dB?) on the other bands, particularly on 30m where my RX antenna (a 30m fullwave wire loop) works best. Lately I've been trying WSPRnet and find that, on 30m anyway, I can hear QRP sigs in EU down to 0.1 Watt by greyline while the Europeans haven't yet heard me below about 1 W out. My TX antenna on 30 is a rotary wire dipole at 13m AGL on the tower at the far end of 100m of RG213, where I probably lose a couple of dB. The RX loop is up in the trees only 20m away from the shack, also fed with a shorter hank of RG213. I haven't yet tried swapping RX and TX antennas over. 73 Gary __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] K3 quick reference guide
Dear Elecrafties, Some years back I came across a neat little quick reference guide for the K2 and it has served me well over the years, reminding me how to do stuff without having to drag out the manual. I printed it out and laminated it to sit in my 'K2 suitcase set' until needed. Well now I'd like something similar for the K3 - preferably the same format i.e. one double-sided sheet of paper, containing not the really simple/obvious stuff, and not the arcane things you're unlikely to need when traveling (e.g. installing new filters? Recalibrating?), just the middle ground: operating tips, every day settings and perhaps what to check first when the mojo dries up. Before I start writing one, has anyone on the list already got one I could either use or adapt, please? If I write one, I'd be more than happy to share the result with the list, perhaps even via the Elecraft site if anyone else would find it useful. I'm tempted also to write it on Google Docs so others can contribute to the development, although formatting may be too tricky for GooDocs. 73 Gary ZL2iFB K3#2887 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] What are you guys using for external speakers?
I had two old 4 1/2 speakers I picked up at a yard sale ... Many of us have decent hi-fi speakers sitting there on the desk already - in my case a lovely set of Bose PC speakers, a fantastic present from my YL. PC speakers (other than Bose anyway!) are cheap. They are amplified, have a wide frequency range and none of the booming or rattling resonances which my homebrew speakers always seemed to have. The Bose speakers have two sets of stereo inputs so I can run both the PC and the rig into them at the same time, controlling the levels independently on the PC and K3. It shouldn't be too hard to provide 2 inputs on others if you're willing to open the box and experiment. Alternatively, I guess you can run the rig's line level output into the PC sound card input, and configure the card to play it through the PC speakers, using the cound card's input level control to set the rig level and output volume control for both PC sounds and RX audio. You *may* need to use ferrites or decouplers to keep RF out of them but I've never had a problem with any of mine. Avoid any with nasty cheap switch-mode PSUs like the plague though! Most seem to run fine on 13.8V byt YMMV. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 Kit - 1/2 nuts on front panel
OK - what kind of wrench can be used on the 1/2 front panel nuts (AF, RF, etc) to NOT scratch the panel? A metric socket worked OK for me, provided it's deep enough to fit the wrench into the socket without fouling the pot shaft (sometimes need to just place the end of the wrench into the socket without pushing it all the way home, but be careful). Sorry, I don't recall the size. Pliers are dangerous but as a last resort you might try protecting the surrounding area of case with some card and be *extremely* careful while you tighten the nut. If you're going to slip, try to make sure to keep scratches within the area that will be covered by the knobs! 73 GL Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 switching to split freq question
There is a more direct method than the one you used. Press BSET (Set VFO B) and then use the MODE button, tap the A/B button to exit BSET - that will retain the frequency for you. Alternately, tap the A/B button to swap VFOs and then tap the MODE button to change the VFO B (now in VFO A position) mode - tap A/B to return the VFOs to their original positions. Hey, it might be good to be able to hold the REV button with one hand, change VFO B's mode, band, antenna, NR or whatever with the other, then release the REV. At present, holding REV seems to lock out band, mode and most other changes except QSYing VFO B using the main A dial. 73 Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 Kit - foam light blockers
Are the foam pieces supposed to stick down to the second layer of LCD or wedged all the way down to the switch substrate? I had the same question a couple of weeks back Terry! Ron told me: That step of the assembly procedure says it all: The blockers should be nearly flush with the front edge of the LCD to block the excess light that leaks out of each end of the display. It's no more complicated than that. Early testing of the K3 showed that enough light leaked out of the ends of the display that you could see it around the edge of the buttons nearest the display, especially in dim room light.
