Re: [Elecraft] Elecraft K3 presentation for a club?
I have a daughter in Norway and send things back and forth all the time. If you are sending mp3 files copied onto a thumb drive there should be no problem as long as the drive is formatted FAT32. All common systems can read those. Mac can read but not write NTFS. Windows cannot read Mac OS. I have burned DVDs and used them on both Windows and OS X. It is true that video DVDs are sometimes have a region code: Roughly 1 - America, 2- Europe, 3 elsewhere. With rare exceptions any player or computer only plays one region or those with no code. The code is so movie countries can control when a region is able to get a movie and so they can't be sent from one region to another. That said there is no duty on CDs or DVDs. I have gone through customs with as many as 200 CDs at one time. These were commercial CDs so there was no issues about copyright. Certain software is subject to export control but for MP3 files the only issue would be copyright which I doubt would be raised. As for stamps - both the domestic and global forever stamps are good for only one ounce - except the global stamp is good for 2 ounces to Canada. Two ounces to England is $2.25 if it contains a rigid object. The really bad news is that an envelope containing a thumb drive more than 1/4 inch thick may well be classed as a large envelope and 2 ounces to England is $6.55. Also since the letter will contain items other than documents you may need to attach a customs declaration. This is no biggie as you just call it a thumb drive and check the gift box. It should be duty free. However you will need to use an envelope that is large enough for the stamp, address and customs form. This may increase your weight. At 3 ounces the price is $3.20 AND $9.55. Disclaimer: With a daughter and grandchildren overseas we send a lot of mail and packages. The above is based on my experiences and reading of USPS regulations. Your post office may tell you different. David K0LUM On Apr 8, 2013, at 1:28 AM, David Cutter wrote: > Fred > > Well, that's quite a story and thank you for sharing it with us.

[Elecraft] PLL Reference Oscillator Range and VCO Test
Hi, I’m currently assembling my K2 but am stuck on the PLL reference Oscillator test. In the frequency counter mode with the probe attached to TP3, I get a reading of 12099.03 kHz, when pressing band + I get 1298.99, Pressing band – I only get 00.467 to 00.475 changing rapidly. (Perhaps the probe is playing up but seems to work with other tests?) However, with an external frequency counter attached I get 12099.00 and no change when pressing band +, but when pressing the – I get 11500 varying to 11700 at high speed. I’ve checked solder joints around that area in particular at R19, RP2, L31, D16 and D17 and at U6 pin 5 am getting 3.90 volts. Also on the VCO test I am getting a reading of 7738.64 but I suspect this will be out due to the PPL test?

Re: [Elecraft] PLL Reference Oscillator Range and VCO Test
Dick, If your internal probe works in TP2, then it is probably OK. Good on the 3.9 volts at U6 pin 5, that part is encouraging, but it does not entirely rule out a problem with the Thermistor board. Skip that for now and first check to see if the problem is in the digital side or the analog side of the DAC. Try the following tests in order. Monitor the voltage at U5 pin 7 while in CAL FCTR. When you tap BAND+ it should go to 4 volts, and when you tap BAND-, it should go to zero volts. If it does not do that, you probably have a problem on the digital inputs to U5. Those come from the control board - check the soldering at U5 pins 1, 2, and 3, and CB U6 pins 19 and 24 as well as U8 pin 10. If RF U5 pin 7 tests good, move on to monitor U6 pin 1. It should change from zero volts with BAND- to near 8 volts with BAND+. If it does not check all the soldering on the back of the Thermistor board, especially checking for solder bridges. If U6 pin 1 tests good, take a big step and monitor the voltage at the anodes of D17 and D17. You should see the same voltage change as you did at U6 pin 1. If not, check soldering and values for R19 and RP2. If no problem was found in the tests above, then you have a problem with the PLL oscillator itself (Q19 circuit). Check resistance to ground from the source of Q19. If you do not see near 270 ohms, check the soldering of R20 and the lead stripping and tinning of RFC14. No problem solved so far? Check capacitors C84 and C85 to be absolutely certain they are 120 pF (marked 121). The makings on those small blue bodied capacitors is very difficult to read and you may have to remove them and check under high magnification and a strong light. If all the above is good, it should work. 73, Don W3FPR On 4/8/2013 6:37 AM, Dickie M0AUW wrote: Hi, I’m currently assembling my K2 but am stuck on the PLL reference Oscillator test.

Re: [Elecraft] KX3 Battery charging
And do not forget that the supplied voltage needs to be correct to charge the cells. I use 2400 mAh cells (Sanyo Eneloop XX) without any problem. As stated in the KXBC3 manual: only NiMH cells rated at 1900 mAH or greater may be charged with the KXBC3. As far as I know the voltage applied should be more than 13.5 volts. Using a standard lead-acid battery as a source will not work. However I have tried to lower the voltage while charging. At 13.8 Volt the current drawn from my power supply is 330 mA. Initially I could sink the voltage to 12.7 Volt keeping 330 mA. Under that voltage, current dropped gradually and at 12.0 I got the "low supply" message on the KX3 display. While charging, the voltage needed to be increased at times to maintain the 330 mA current flow and the "low supply" message showed at 12.5 volt, which proves that you cannot get a full charge on that voltage level. The bottom line is: Use a power supply that can deliver at least 0.5 Amp. at 13.8 Volt as a "charge only" option. 73, Peter - PA0PJE Op 2013-04-06 21:22 schreef Matt Zilmer: Any capacity NiMH cells are OK. They will charge at the rate of 200 mA.

Re: [Elecraft] K1 KFL1-4 Band indent
Steve, You will have to check the crystal frequencies on the 4 band board. Hopefully the builder mounted them so all the crystal markings can be seen. Look at X1 - if it is 29.000 MHz, it has 15 meters, but if the crystal is 26.050, it is built for 17 meters in place of 15. Also the 30 meter crystal X3 should be checked to complete the story. If it is 18.000 MHz, the board was built to work in a K1 with a 150 kHz tuning range. If it is 18.100 MHz, it was built to work in a K1 with an 80 kHz tuning range. If the buyer wants to change the top frequency band or the tuning range, crystals can be purchased from Elecraft - all that is necessary is to change the crystal(s) and re-align the bandpass filters. 73, Don W3FPR On 4/8/2013 9:50 AM, Stephen Roberts wrote: I have a 4 band board for a K1 that I want to sell, but not sure what bands are on it.

Re: [Elecraft] KX3 Battery charging
Yes, 13.8VDC is required to charge. The voltage drop has to be above a certain value to properly regulate the charge voltage and current level. I had a set of 1750s that I put in the KX3 and charged. They charged faster than the nominal C/10 rate, but still charged up just fine. I think the 1900 mAH minimum is stated so that the charge rate is C/10 or less. But lower capacity cells will also charge, just at a higher rate. I'm using a 9A variable switcher set to 13.9VDC output. This PSU also powers other loads. It had to be "ferrited" half to death to kill the switching harmonics. :) 73, matt W6NIA On Mon, 08 Apr 2013 16:22:35 +0200, you wrote: >And do not forget that the supplied voltage needs to be correct to >charge the cells. > >I use 2400 mAh cells (Sanyo Eneloop XX) without any problem. > >As stated in the KXBC3 manual: >only NiMH cells rated at 1900 mAH or greater may be charged with the KXBC3. > >As far as I know the voltage applied should be more than 13.5 volts. >Using a standard lead-acid battery as a source will not work. > >However I have tried to lower the voltage while charging.

Re: [Elecraft] [OT] Lead-acid battery question
Sounds like your setup is not providing enough run time to fully recharge the battery. Rather than fiddling with the existing engine settings, I would suggest getting a small 1-ampere or so "trickle charger" from a place like Wal-Mart or Sears. You will not need anything larger, and the low-rate should be safe for the battery long-term. Running the engine once a week seems excessive if all you want to do is test it tomake sure it starts. Once a month is all I used when I had a 15-KW diesel set, and it never failed to start in 20+ years. The trickle charger of course runs from the standard commercial power outlet. You do not need to disconnect the existing charging system, just hook up the new charger in parallel. - Jim, KL7CC On 4/8/2013 8:15 AM, Vic K2VCO wrote: I know there are those on this list who can help me.

Re: [Elecraft] [OT] Lead-acid battery question
A small charger will work if the battery is still good. Before I assumed that, I'd charge the battery with a good charger, then do a load test to see if it actually stores power. I've had "sealed" batteries that were damaged in shipping. Looked fine, but outgassed and dried out. Took a couple of years. Usually, the periodic "run" is to bring the oil to temperature and distribute it around the engine, not primarily for battery charging. -- Lynn On 4/8/2013 9:51 AM, Jim Wiley wrote: Sounds like your setup is not providing enough run time to fully recharge the battery.

I see that my original post was not clear. I should have said that after the first instance of a dead battery, after the battery was tested and pronounced good, I replaced the VOLTAGE REGULATOR. I'm not sure about the type of electrolyte, whether it's gel or liquid, but I think it is liquid. The battery is sealed, though. The capacity is 665 AH with "540 CCA."

Re: [Elecraft] Headphones $11.99
Dave, I spotted these in the accessories section of my local T-Mobile store. Might they work? I picked up a couple on impulse, and they have great sound for such tiny enclosures. They about 2 inches tall and maybe 1.5 inches in diameter. They are battery powered, with a computer serving as the battery charger (via a USB port). Supposedly you get six to eight hours off of a charge. http://www.musemini.com/copy-of-muse-mini-portable-speaker-non-bluetooth/ If something like this looks useful, and they don't ship to the UK (and T-Mobile stores there don't carry them), let me know and I can snag one for your and send it along...

Re: [Elecraft] [OT] Lead-acid battery question
Well my bet would be a bad battery. Seems that either the self discharge rate is high, because it is defective, or the controller for the automated cycling is drawing excessive current and discharging the battery between cycles.The fact that a battery "takes" a charge does not mean that it will maintain it. Regarding chargers I have had good experience with these: http://batterytender.com/products/automotive/battery-tender-plus-12v-at-1-25a.html Don't be scared off by the price tag as they can be had for far less. In the $35-$40 range if you shop around.I use these for my backup gel cells and mostly for maintaining my motorcycle batteries over the winter.

[Elecraft] P3 SVGA; chars randomly omitted during Tx
I have been working PSK31 and CW using the message memories in the SVGA adapter. I have only had my SVGA a short time and have just got around to trying digital modes with it. I have noticed that random characters are being omitted from Tx even though they show in the transmit box. A replay will find those same characters okay, but different one(s) will be omitted. As I say, the characters are at random. Has anyone else noticed this? My computer is not on, so I don't suspect the USB to Serial cable, but maybe I need to check the correct routing of the cables.

Re: [Elecraft] [OT] Lead-acid battery question
Vic let me clarify a few issues. 1. At 665 AH your sealed battery is almost certainly a wet battery (i.e. not a gel). 2. A charging voltage between 13.5 and 14.2 is normal. 14.5 is a bit high unless the charger is temperature compensated and the weather is very cold (in the area of your generator). Another cause would be if you measured the charging voltage without a battery attached (i.e. no load). In any event your real problem does not appear to be too high a charging voltage. 3. A measured voltage of 11.5 is a fully discharged battery. A 1 A trickle charger would need 665 hours (actually even more because of inefficiencies) to fully recharge that battery. 4. Why did you replace the old battery after 10 years? In your almost ideal circumstances it could easily last 25 years. The nature of lead acid batteries is they fail when fully discharged. That can kill even a new battery which may be the case now. 5. Logically I must ask: Have you fixed the original problem? Battery failure is likely a secondary problem. Ruling out two bad batteries (the old and new batteries) has the generator become hard starting or else is there another drain on the battery? To find your problem you need to get a fully charged battery and monitor the operation of the generator. Have you cleaned all the terminals and otherwise verified the cables? Does it start hard? Does the started solenoid get warm when not in use? Is there 13.5 to 14.2 volts on the battery posts (don't measure the cable terminals) when the generator is running? When the generator is off is there a battery drain? It may take a milliamp meter to tell but be careful not to use it while charging or you may smoke the meter. Remember ammeters are always placed in series, never in parallel (instant smoke).

Re: [Elecraft] PLL Reference Oscillator Range and VCO Test
Dick, All that sounds good, and may not be the source of your problem. You mentioned that you had a frequency counter. Do the CAL FCTR test with BAND+/- using your external frequency counter and see if you obtain the expected frequencies. If so, take a very good look at your internal counter probe, especially the insertion of the crimp pins into the housing. If those crimp pins are not inserted correctly (with the crimp pin locking tabs locked in the rectangular holes of the housing), the signal from the test point may not be adequate getting to the control board. Also the braid on the coax must be on the pin closest to the left side panel when the probe is attached to the Control Board. I have not seen it lately (in the past 2 or 3 years) but a while back we had trouble with the frequency response of Q9 and Q10 on the Control board. If your external counter test is good and the probe is in good shape, you could try replacing Q9 and Q10 with 2N transistors - they will work fine up through all the frequencies that internal counter needs. 73, Don W3FPR On 4/8/2013 2:23 PM, Dickie M0AUW wrote: Hi Don, Many thanks for your quick reply.

Re: [Elecraft] [OT] Lead-acid battery question
The charging voltage was measured with the battery connected. Although it says "ca 665" on it, judging by the size it must 65 AH! I charged it for a period of 12 hours with an initial charging current of about 7A, which dropped to 2A. I replaced the old battery because it went dead, and then when I charged it it did not recover. I think the voltage regulator was bad and not producing enough charging voltage. Then the battery was damaged because I didn't notice it was dead for a couple of weeks. The new battery also went dead. I then checked the charging voltage and it was 13.8V. I thought it was marginal, so I replaced the voltage regulator. Now I'm getting 14.5V when the engine is running. But I am thinking that I damaged the new battery when I allowed it to die before replacing the voltage regulator. The connections have been cleaned. It is not particularly hard to start (cranks for about 5-7 seconds and starts). No drain at all when it is off.

Re: [Elecraft] P3 SVGA; chars randomly omitted during Tx
Thanks for the prompt reply, Paul. My comment/question about the cable was a passing thought about having the cable plugged into the correct one of two jacks. I just verified that it is. The transmit mode is set up for ^T. Perhaps this is normal, but no matter what mode, it begins to transmit as soon as I call a memory. Using ^T it also transmits when I begin typing unless I use a ^R. After using a ^R, I can then use a ^T to have it transmit. In summary, the memories were being transmitted as soon as I called them.

[Elecraft] K3 PA Temp Reading Unstable
Hi folks K3 here has developed a slight problem with the PA temp sensing.. it is flicking between normal and +40 several times per minute. noticed the fans starting in a very cold shack RX only running. This may have been happening for a while, but never noticed until the cooler mornings. Havn't taken a look at the PA or circuits yet, wonder if another user has a start point ?

Re: [Elecraft] DATA A Reverse? AFSK A Reverse etc?
"Reverse" is exactly the same in data modes as in CW - the "reverse" setting uses the opposite sideband to the "normal" setting. Some digital modes, e.g. BPSK, will work regardless of which sideband you use (like CW). Others, notably RTTY, are sensitive to which sideband you use (like SSB). DATA A and PSK D are USB, so DATA A-REV and PSK D-REV are LSB. AFSK A and FSK D are LSB, so AFSK A-REV and FSK D-REV are USB. 73, Rich VE3KI VA2FSQ wrote: Can someone explain exactly what the " Reverse" functions is?

Re: [Elecraft] DATA A Reverse? AFSK A Reverse etc?
Keep in mind what's "normal" depends upon where you are. My recollection is that MTTY used to transmit on USB as non-inverted. I think USB RTTY is standard elsewhere too. I don't think the argument has ever been settled which sideband is the "normal" one for CW either. I wonder if there is a correlation between which side of the road one drives on that the proper sideband to use 73 de Brian/K3KO On 4/8/2013 21:28, Richard Ferch wrote: "Reverse" is exactly the same in data modes as in CW - the "reverse" setting uses the opposite sideband to the "normal" setting.

Re: [Elecraft] DATA A Reverse? AFSK A Reverse etc?
The K3, like every other amateur transceiver I know of, uses LSB for its RTTY-specific data modes (AFSK A and FSK D). This is the standard amateur convention for RTTY. Note that RTTY outside the amateur bands may be different; the choice of polarity for RTTY is an arbitrary convention which is not the same in all services. Regardless of which sideband the transceiver uses, if you are using software to decode and encode signals the software usually provides a way to choose either polarity. The MMTTY software assumes the radio is in LSB. You can use MMTTY for amateur RTTY with the radio in USB (FSK D-REV or AFSK A-REV), but to do so you need to press the "Rev" button in MMTTY. Some multi-mode digital-mode software assumes the radio is in USB for all data modes including RTTY; there is usually a Reverse option in such software that you can use so the software will work with the radio in LSB. As for CW, you can use whichever sideband you prefer (e.g. depending on whether you are tuning up the band or down the band, or on the presence of nearby signals either above or below the desired signal's frequency). The stations you are contacting cannot tell the difference. Be that as it may, the K3 uses LSB for CW; CW-REV in the K3 is USB. 73, Rich VE3KI K3KO wrote: Keep in mind what's "normal" depends upon where you are.

[Elecraft] Using K3 for 2m EME
I wonder if anybody has any ideas about this. Prior to my trip to TX5K, I used my K3 for receive on 2m EME by setting up the transverter port for a 28 to 144 MHz transverter, and I just plugged my 28 MHz converter into that nicely isolated receive port. The receiver worked great, but I was eventually interested in getting the internal 2m transmitter module so I could use the more stable K3 on XMIT too. I was using my old IC746 as a separate transmitter on 2m EME, and - as most of you know - it drifts quite noticeably every sequence. And besides, I thought for traveling it would be convenient to have both 2m and 6m capability in one lightweight box. So, now I have the 2m module installed in my K3 ;-) The problem is that I can no longer use the transverter portit is hard wired to the 2m module. And apparently, the only 2m connector is the new one (a BNC called antenna jack #3) that is used for box receive and transmit. So there seems to be no way to use the K3 with a separate protected receive line anymore! For 6m EME, there is no problem - I just bring my 6m preamp line into the separate RX ANT jack, and the 6m transmit power goes out through the UHF antenna jack #2. For 2m EME, though, I can't figure out how to bring in a separate receive line (either on 2m from my tower mounted preamp or after my receive converter at 28 MHz) and still be able to transmit on 2m. The K3 does not support cross band operation, so I cannot use the RX ANT jack to safely receive my converter output on 28 MHz and still transmit using the internal 10w 2m module. Has anybody figured out a way to modify the circuitry or software to provide a separate receive line for 2m operation? It seems like I just made a very expensive mistake, and should have just bought an external transverter so I could retain use of the separate transverter receive jack on the rear of the K3. If not, I guess I will just have to go back to using the IC746 for my transmitter on 2m, and defining a second transverter setting for the K3 that will allow me to bring in my 28 MHz converter output into that receive only jack. This latter option DOES seem to work, but of course, the internal transmit capability of the K3 on 2m is thrown out the window. Of course, there is always the solution of adding more sequenced external coaxial relays to switch the K3's solitary new BNC antenna jack #3, between my driver amp input and my 2m preamp output. However, the whole point of this expensive exercise was to try to take advantage of the great separate receiver antenna capabilities offered by the K3 on all other bands, apparently EXCEPT if you add the built-in 2m option :-( Any suggestions would be greatly appreciated.Elecraft Tech Support suggested that I ask users for ideas, since they also are baffled on how to make this work, and I guess are surprised at my application.

Re: [Elecraft] Using K3 for 2m EME
Lance, My guess is that you will need to change to the external XV144 transverter which does have the capability of using separate TX and RX antennas (selectable at build time). The internal transverter does not have that capability. Yes, it does sound like an expensive oversight. 73, Don W3FPR On 4/8/2013 7:37 PM, Lance Collister, W7GJ wrote: I wonder if anybody has any ideas about this.

[Elecraft] K3 power out issue
I just noticed that one of my K3s seems to have a power out issue. Specifically, when keying for the first time, the output power seems to be overshooting what it is set at.

Re: [Elecraft] K3 power out issue
Update Not sure how I missed this, but I just determined that this ONLY happens when NOT in SPLIT mode. And it happens on BOTH K3s. I had my other K3 in split and did not notice it. I can reproduce the same symptom on both K3s when NOT in split but - when in split both are fine. Doesnt matter what band nor does it matter if VFO A and B are on the same or different frequencies. When NOT in SPLIT the output power overshoots for the first 3 dahs every time the power level is changed either up or down.

Re: [Elecraft] [Moon-Net] Using K3 for 2m EME
Lance , As you know I run the K3 for eme, as well. I chose the new L-series DEMI transverter so it was built to my spec as perfect interface with K3. It seems most of the ham world is unfamiliar with separated Rx and Tx (though Elecraft did a super job on the KVX3 option...but then forgot it when they designed the K144XV). Well, probably assumed most users would be working FM repeaters or using brick amps with internal switching for CW/SSB. EME is just too niche. Only suggestion is modifying the K144XV to eliminate TR switching; not sure how easy that would be. keeping the K144XV inside the K3 cabinet is problematic with running extra cables...or add an external coax relay (maybe the simplest solution). I will be incorporating the 2M module in the KX3 when it is available. It will be a standard common ANT connection so will require external TR relay to separate Rx and Tx for preamps and PA. I will likely only use it as 28-MHz IF for mw transverters and built the required ckts into the mw transverters (my 3400-144 and 10368-144 transverters have common IF). BTW my DEMI L144-28HP DRX is a dream for working adaptive pol on 2m-eme. Unfortunately, DEMI made only one. With the IQ+ as competition, its doubtful it would be an item that DEMI will manufacture.

Re: [Elecraft] [OT] Lead-acid battery question
665 "CA" would be cranking amps (normal temperature), vs. the lower "CCA" rating which is cold cranking amps. Unlike marine or RV batteries, a starting battery have low ampere hours for its size: it's optimized for high current loading, not for run-time. I agree with those who suggest a good quality float charger to continually maintain the battery at full charge. Be sure it has a true float mode (not just an automatic charge cut-off), and avoid bargain priced chargers (they often have poor voltage regulation). I wouldn't be surprised if your generator controller has one; perhaps it has failed. I hope you get the problem fixed! --Tim (KR0U) __ 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] ARR P50VDG Problems
Hi Group, Just recently hooked a Advanced Receiver Research P50VDG 6 meter preamp to my primary K3/10. Right off the bat I heard a internal relay start chattering with the preamp on and RX ANT setting engage (of course this is all in receive mode). Turned everything off to re-evaluate connections and setup correct. I then put the K3 into attenuation mode to eliminate some of the gain, no luck. Consulted with some fellow hams and Elecraft, Elecraft thought the 24 dB of gain might be too much and causing an overload on the front end (and the relay chatter). To make a long story short, I tried the suggestions and still having the same issue. So I took the P50VDG to my secondary K3/10, works like a champ and as I would expect. Now I’m wondering what is different about my primary K3. Short video of the noise which seems to be produced by the relay chatter: https://vimeo.com/63535627 Anyone experience this or have some suggestions? My primary K3/10 is at my remote station using the K3/0, my secondary is at home and backup.

Re: [Elecraft] [Moon-Net] Using K3 for 2m EME
Hi Ed, TNX for your thoughts. Yes, an external transverter would have been more flexible, but I was hoping for something self contained. Oh well I wired up a pair of BNC coaxial relays to my 2m relay switch box, and that seems to safely terminate the output of my 2m preamp during XMIT, as well as redirect the 2m output from the K3's new #3 coaxial connector to the input of my solid state driver amp. It all seems to work now, so I am anxious to see how the stability looks on JT65 tmrw when I give it an actual workout on 2m EME. Sure am glad to have the K3 home again!
