[Elecraft] 4A4A Revillagigedo Island DXpedition
P3 and the K3's subreceiver Just paid for themselves this morning! Heard 4A4A on 7.014 working split and he had 'em spread out to about 6 KHz up. Managed to easily find a spot between the last 2 he worked and even with my low antenna and only 100 watts, got 'em on the second call. Sure would be nice to have the VFO B cursor with a line similar to the marker sticking up above the noise floor, or allow the VFO B marker to follow the cursor when working split. That would make it much easier to spot the TX frequency precisely when chasing a pileup like this one.

Re: [Elecraft] Remote control of K3
There are many possible solutions for RC today. What I describe here has one specific advantage: it is very cheap to implement. I am using HRD. My preferred opr mode is CW so I had to buy a winkeyer. I use Logmein.com for remote access to the shack. Since my IP address is dynamic, I am using DynDNS.com. Both services exist in a free-of-charge version which is adequate for my purpose. I did operate with HRD on the remote PC in a client-server configuration for the first few years. It gives a faster responding control over the K3, but the serial link which is needed for CW is very sensible to link quality and drops out from time to time - very annoying, so I decided to use a remote desktop solution. The solution with "HRD-over-Logmein" has the following advantages: - essentially free of charge (must have a winkeyer, must have a shack PC) - works CW (and other modes) - can be operated from any PC (does not need to have any special programs installed except for Skype) - the log is always on the same PC (using HRD log) - it operates fast enough to work DX pile-ups where timing is essential NB: I am now using an USB media controller (dial knob) from Griffin on the remote, so I can dial over the band in the same way as in front of the K3. This is somewhat nicer than using the mouse or arrow-keys. 73, Poul-Erik OZ4UN -Oprindelig meddelelse- Fra: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] På vegne af M Cresap Sendt: 4. marts 2011 02:24 Til: Elecraft List Emne: Re: [Elecraft] Remote control of K3 I have been using the N4PY Pegasus Plus software package for some time now with great success with the K3, transverters, amplifiers, and rotor ( www.n4py.com).

[Elecraft] K3 Front Panel Headphone Jack Problem
Hi all, I have been experiencing a problem with the front panel headphone jack. Regardless of the ¼ plug used, I must put side pressure to get both audio channels to function, and then the weight of the cord will cause the connection to be lost again. I realize the jack most likely needs replacement and that is where my question comes in. Has anyone had this issue and/or replaced one of these? I can purchase the part from Elecraft, but should I damage the DSP board, Ill need to purchase a new one. Also, if Elecraft attempts a repair, and they are not successful, again, I am on the hook for a new board, about $400.00. I would like to be able to use the front panel jack, I know there is one on the rear, but the convenience is not there. So, if anyone has any hints or experience on replacing this part, I would really like to hear from you. I cant imagine I am the only one having a problem as this jack has rarely been used, until my current need came up. Thanks to all in advance for your input.

[Elecraft] P3 VFO B marker.
Hi Alan, I see that there have been some wishes expressed on the List about marking the frequency of VFO B on the P3. FWIW the scheme that I used with my old homebrewed panadapter (now retired) was to mark the frequency of VFO B by a vertical line, which ran from the top to the bottom of its spectrum display. The main reason for making the marker line so long was to prevent it from disappearing should some very strong signal land on the same frequency as that of VFO B. The problem with a typical inverted delta marker is that it can be difficult to see in the heat of battle, and it will bounce as well of course. I use the same type of marker for VFO B when using my Perseus as a panadapter, which has both a spectrum and a waterfall display. 73, Geoff GM4ESD __ 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 Front Panel Headphone Jack Problem
I wanted to avoid wear and tear on the jack and instead am using a Radio Shack Stereo Audio Selector, which is a 3-way switch plugged into the rear speaker jack. I have my old, powered Sony computer speakers (which I like a lot) and two different headphones plugged into the switch. I just bought a 2-way switch that has three jacks at Amazon for $7.95, the third jack being a yellow video jack. That was much cheaper than the Radio Shack switch, which is probably now discontinued. The mini-phone jacks in the back on the KIO3 board seem fragile. The plugs dont seem to seat securely, which is another reason I wanted to avoid using them often.

Re: [Elecraft] Band Changing Macro
You can go to the last used frequency and mode on a band by configuring CONFIG:MEM 0-9 to BAND SEL. I also use the M1-M4 quick memories for each band. I set up all of those memories using the Elecraft K3 Frequency Memory Editor Program. This information is on page 16 of the current manual. I use free DXLab Suite of programs (http://www.dxlabsuite.com/) including the Commander rig control program. That program has ten banks of ten memories each so selecting a memory takes one or two mouse clicks, making it much more flexible than using the memories in the K3.

[Elecraft] K3 and K2 - concerns about power into RX ant
There have been several concerns expressed on the reflector about how much power is being sent into the K3 RX antenna (also applies to the K2 with a K160RX option). Rather than guess if that level is safe for the radio, why not just measure it? It is easy to do. Try this: Do you have a wattmeter that is accurate at the 1 to 2 watt level? If so, connect it to the receive antenna (make certain the antenna is terminated into a 50 ohm load either within the wattmeter or with an in-line wattmeter, connect the dummy load to the ANT side) - note that for this measurement, the receive antenna is the "transmitter". If you do not have an accurate QRP wattmeter, then connect the antenna to a dummy load and measure the RF voltage across the dummy load with an oscilloscope or an RF Probe. With an RMS reading RF Probe and a 50 ohm dummy load, 7.07 volts is 1 watt and 10 volts is 2 watts - with an oscilloscope (use a 10X probe), the peak to peak voltage would be 28 volts for a 2 watt signal and 20 volts for a 1 watt signal. If your dummy load is fully enclosed, you can gain access to the center conductor with a UHF TEE adapter. The K3 generates a HI RFI message in the VFO B display if the level is about 1 or 2 watts, so we can likely guess that level will cause no harm, and it should be below the level where the COR activates. If you have more than 2 watts from the receive antenna (from any transmitter running at its highest power and using any TX antenna) into a 50 ohm load, then I would recommend some secondary protection. If the level with your highest transmit power is less than 1 watt, then I would not worry about it. 73, Don W3FPR __ 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

If you work 40, 80, or 160M, diversity reception with a dedicated RX antenna can be a VERY good thing, helping you hear things you otherwise might not have heard. If you are a DX chaser, you can listen on your TX frequency when working split. That can help a LOT when trying to find a place where your signal might stand out from the competition. The P3 is also quite helpful in the same way. If you are a contester, you can use the second RX to search for multipliers while you're CQing (not while transmitting though). If you work VHF (or even 10M) and are looking for band openings, you can monitor two frequencies (on the same band) at the same time, one in each ear (or external loudspeaker), for example, one in the CW portion, the other on SSB. Again, the P3 is also quite helpful in the same application. I've used my 2nd RX in all but the last application. 73, Jim K9YC __ 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] 2nd RX
In a contest, one can work something called SO2V, where off a run frequency, you scan the band away from your run frequency, or move it to a new spot and pick it off while maintaining your run frequency. Not easy to do (the distraction and mental breakdown quotient is very high for this kind of stuff), but extremely handy if you can get your brain to do it. You can put the other RX on another antenna and listen to other bands at the same time, including AM broadcast or HF broadcast. I do that a lot during the summer listening to Yankees baseball games. I will often just leave the second RX on the other frequency. Why use this quality of RX for that purpose? I can listen to them using SSB on a RX antenna and use fast AGC on a pretty bad signal that would be intolerable listening AM. I set the frequency to 880.000 kHz and the audio is perfect, no trace of Donald Duck. It even renders music acceptably though not quite perfectly. When noisy I narrow the bandwidth for best balance of "intelligible sound" and signal-to-noise. I use DDR for 160 and 80. The improvement in RX is immense and allows me to pull out very poor signals. The spread of noise in the headphones allows me to effectively ignore the noise. Setting the TX in the clear with working someone split is invaluable. I often run up the bandwidth on the second RX (listening to the split frequency) to 2.7 kHz just to hear the range and detect the DX's pattern on RX. There was something else but cannot recall at the moment... 73, Guy On Fri, Mar 4, 2011 at 12:19 PM, Mike WA8BXN wrote: > If you are operating split frequencies for transmit and receive, the a > second RX lets you listen to both frequencies at the same time. > > 73 - Mike WA8BXN > > > __ > 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 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] Heil Mic--settings
I was hoping someone using one of the Heil Headsets (the 4 element) would respond to this recent mic thread. As a contester, I use these on both my K3's and would be interested in the settings folks use. I've done quite a bit of CW with these great rigs, but not much SSB, so have never been sure that I've got the settings (gain, compression) at best spot. Obviously, I'm looking for a more competitive sound, but, not offensive! Thanks.

Re: [Elecraft] 2nd RX
Hi Lee, There are three reasons you might want the sub-RX: (1) diversity; (2) listening to both your RX and TX frequencies when operating split; (3) monitoring one band while you operate on the other. The K3's sub RX has identical performance to the main RX, so it excels at all of these applications. 73, Wayne N6KR Lee Buller wrote: > I am curious > > What is the benefit of a 2nd RX in the K3? ... __ 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] 2nd RX
Actually there's a fourth reason. If you use QRQ CW mode (ultra-fast break-in), you can't normally use split or RIT. But if you have the sub receiver installed, you can transmit on VFO A and receive on VFO B, which will achieve the same goal in many situations. 73, Wayne N6KR On Mar 4, 2011, at 10:10 AM, Wayne Burdick wrote: > Hi Lee, > > There are three reasons you might want the sub-RX: (1) diversity; (2) > listening to both your RX and TX frequencies when operating split; (3) > monitoring one band while you operate on the other. > > The K3's sub RX has identical performance to the main RX, so it excels > at all of these applications. > > 73, > Wayne > N6KR > > Lee Buller wrote: > >> I am curious >> >> What is the benefit of a 2nd RX in the K3? ... > > __ > 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 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] 2nd RX
And the same on HF. Working pile up is a lot easier in the contest when you have two antennas beaming different directions and 2 RX on the same frequency. In our case EU signals on the western antenna are in the left ear and JA/Pacific signals are in the right ear. Since both receivers have independent AGC strong EU signals do not offset AGS on the eastern antenna and allow one to hear weak signals from Pacific DX stations in the pile up. 73, Igor UA9CDC > And another... > > With a suitable dual rx 2m transverter and two arrays I can listen to > two directions at once.

Re: [Elecraft] T1 build...
Ross, You are looking too hard! Most of the Elecraft tuners use the same technique - the selected relay is activated and the return path flows through all the rest of the other relay coils - there is not enough current through any one coil to activate them, and it works quite well - one more piece of "magic" that can be done using PICs. 73, Don W3FPR On 3/4/2011 1:30 PM, Ross Primrose N4RP wrote: > Got my T1 kit last night, got the parts inventoried, and got up to where > I need to start winding the toroids...

Re: [Elecraft] 2nd RX
Many Hams find value in having a good second receiver in the shack. I'm sure the heavy-hitting contesters and dx-ers on the list here will give you many ways they use the subrx to enhance their pursuit of the latest elusive contact, but there's also the more basic idea of having a world-class second receiver on the operating desk that can be used at the same time as the main receiver. When equipped with the KBPF3, the subrx covers the entire spectrum from 500 kHz to 30 MHz and the 6 meter bands and provides all the same advantages and specifications as the K3's main rx.

Some other reasons are to listen to the pile while listening to the DX station when the DX is working split and to search the band with one receiver while monitoring a net or waiting for a QRX to return.

Re: [Elecraft] [K3] Preferred or Popular Mic For the K3
Please, WRONG, No. I made reference to "desk mic stands with PTT" NOT Desk mics. The point was to source a stand for inexpensive alternatives to the expensive Heil Goldline style mics that need a stand. Radio Shack and othes sell mics like this for very reasonable prices but the only source of a stand for them that has a PTT switch is the one from Heil. There are many "deks mics" around, and most if not all can be adapted to the K3. ...bill nr4c -Original Message- From: Phil Hystad [mailto:phys...@mac.com] Sent: Friday, March 04, 2011 4:49 PM To: Hector Padron Cc: n...@widomaker.com; elecraft@mailman.qth.net Subject: Re: [Elecraft] [K3] Preferred or Popular Mic For the K3 Both Icom and Kenwood make desk stand mics with the PTT switch in the base.

[Elecraft] Mic for K3
I bought the standard mic from Elecraft with my K3 kit. I thought it quite an expensive option. It works perfectly well, but it is somewhat bulky. The K3 has such a vast range of audio adjustment on rx and tx I have tried many other mics on it and all work perfectly well. I am very particular about audio quality. And do serous on air tests with other stations. But probably 95% of my use is on CW. As I prefer to use a headset, I bought 5 electret inserts at a rally for one pound (for 5) and made up a boom device These seem to be at least as good, or better than all the other mics I have tried. so the convenience and neatness of the headset/boom has made the standard mic almost redundant. 20 pence is my idea of good value! 73 David VK3DBD/G3SCD __ 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 issue with Keying
Properly operated, the K3 has a pristine CW signal, using a number stream from firmware to directly create the 15 KHz CW signal in the TX Digital to Analog Converter. Since all amplification/conversion is linear after that, the same signal emerges properly shaped at the antenna jack. The K3 has a constant and well deserved reputation for excellent CW that does not bother people even just a few hundred Hz away. There ARE ways to make a signal from a K3 or any other properly designed transceiver have key clicks at the antenna. They almost always involve an amplifier. Assuming (bad word) your power supply can actually supply a stiff 13.8 volts, a K3 with key clicks barefoot has something busted and needs to be sent back to Elecraft to get it diagnosed and repaired. 1) Probably the worst is to try and run break-in or semi-break-in into an amplifier whose internal relays cannot follow the speed of the CW. What then happens is hot-switching, where the relays are making and breaking contact during the sent signal. The extreme sharp edges of the RF made by the hard relay contacts of the amp will be heard well above and below signal. This is also capable of doing dreadful things to the amplifier, including destroying tubes, pi-networks, bandswitches, relays, meters, tube sockets, nearly anything except the input circuits and power supply. 2) The other biggie is to run 100 watts into anything other than a pair of 3-500Z or a 3CX1200A7 and let the amp ALC throttle back the K3 power on a baud by baud basis. This will generate clicks, because the ALC *MUST* quickly shut down power to protect tubes -- the pristine CW signal is being chopped ASAP to keep from toasting grids and turning your expensive final tubes into lamp fodder. DO NOT use amp ALC to set levels. Do that with the K3 power knob to set the proper level, and set your ALC levels somewhat above that ONLY to protect your tubes if you forget to back off going from running 100 watts barefoot to needing 60 watts to drive an amp. 3) If you tune well off your antenna's resonance without retuning, that will raise grid current, you will be operating your amp outside its linear zone. This will flat-top the signal, creating sharp edges to the CW envelope that are not there at the K3 output. 4) Aside from using an amp improperly, an amp can have a range of problems requiring repair or final replacement that will produce key clicks from a perfect signal on its input. These need to be separately diagnosed and fixed on their own merit. 73, Guy.

Re: [Elecraft] K2-KBT2 battery
Yes, James. I always insist on good quality battery and use intelligent chargers.

Re: [Elecraft] [K3] Preferred or Popular Mic For the K3
> I'm not aware of anyone making a desk mic stand with PTT other than Heil" That's because they spend the most money advertising to hams. It is NOT because they are the best (they are not even close). If you want a good PTT desk mic, you should be looking in the realm of 2-way radio and commercial sound (paging mics). Shure (based in Evanston, IL) has been making a good variety of models of very good PTT desk mics for at least 80 years. Turner desk mics, long discontinued, were excellent, but are available on the used market. Astatic also made a lot of this sort of mic, the best known being the D104 and its many variants. Look for this stuff on the used market. 73, Jim K9YC __ 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
