Re: [Elecraft] Need Help with XG1
Thanks Don. Unfortunately, all those variables test OK. I've gotta fix my old scope! I think that voltage must be an indication that the transistor oscillator is at least drawing the right amount of current through R9. I'm going back to recheck all my work on the default output attenuator. Must be something there, particularly since the additional stage of attenuation when I switch in the 1 Uv position seems to be working properly. 73, Pete At 02:30 PM 1/28/2009, Don wrote: Pete, Do you have the proper voltage on Q1? Check for 1.22 volts at the cathode of U2. Also check the value of R3 and R3 with your ohmmeter. It sounds like you have replaced everything important, but if you had enough RF to fry the resistors, you may have damaged the switch contacts at the same time. You should be able to determine the resistance through the switch with your ohmmeter. Do that for both poles, and both switch positions. 73, Don W3FPR Pete Smith wrote: Thanks for the idea - I removed both D1 and D2 from the circuit - no improvement. The signal is quite audible (in the 50 uv switch position, and barely audible in the 1 uV position, but doesn't move an S-meter that was formerly tested with it and registered S9. Anyone else?

No, sorry - I meant that in the 50uv position it generated an S9 reading.

Re: [Elecraft] Request for NR and NTCH inside AGC loop
It reminds me of methods to receive weak signals with other radios. Adjust crystal filters for a single peak, reduce RF gain, play with ATT K3 makes these steps unnecessary. All what K3 needs for NR (and NTCH) is to put them inside the AGC loop, like for instance in IC7000. NR at level 1 or 2 does not reduce the signal strength too much but also does not bring signals out of the mud. Ignacy I've found that adjusting AGC THR makes quite a difference. I normally have THR at 4 but when I need the NR, I adjust THR to 6 or even 7. I set NR at 2-1 or 2-2. With this setting, I normally do not have to turn AF gain up. 73, Gary W7TEA Ignacy wrote: I am not the first one writing that NTCH is outside the AGC loop and that NR reduces the signal strength. With NR, less on strong signals but much on weak signals. For example, signals that are buried in noise seem to be brought to life with NR 3-3 but the AF gain needs to be all the way up, or more. Ignacy John Lemay wrote: Ignacy Maybe your rig has a problem. NR does not affect the signal strength at all. It does however reduce the audio level, depending on how aggressive the setting is.

Re: [Elecraft] Upgrade question
Jim: I don't think that should be a problem. The crystal has only 2 leads, so if you can pull it a little while heating up one of the leads, the end you are heating will break loose. Do the same with the other lead and it should come out painlessly. Then clean up the holes in the PCB. You probably won't even damage the old crystals. If you want to remove a component with more than 2 leads, then it gets trickier because the multiple leads that aren't being heated are enough to hold the component in place. That's when it's usually best to destroy the component and remove the leads one at a time. Not so with a crystal (or other 2 lead components).

Re: [Elecraft] Upgrade question
Jim, To remove the crystals, first clip off the ground lead. Then most likely you can heat one of the pins while putting a bit of pressure against the side of the crystal. As soon as you feel it move, heat the other pin and repeat. It will get easier after 2 or 3 passes, and you can get the crystal out one lead at a time. Alternately, if you have 2 soldering irons, you can heat both pins at once. The leads are not connected to the case, so the case will not act as a big heat sink. Be gentle so you do not damage the board. 73, Don W3FPR Jim Giercyk wrote: Thanks guys! I purchased all of the updates from A to B.

Re: [Elecraft] Upgrade question
Hi Jim, I've had good results using a GC Electronics Solder Popper (part # 12-2157). It's a 30W soldering iron with a built-in spring loaded solder sucker. While it's certainly not equal to something like a Hakko 808, it's adequate for occasional use. And at less than $40, it's about 1/4 the cost. Note, however, that it seems to run hotter than a normal iron, so you have to be careful not to linger on PC board connections. It would be a good idea to try it on some junk PC boards to get a feel for it before using it on your K2. 73 -- Joe KB8AP On Jan 29, 2009, at 6:41 AM, Jim Giercyk wrote: Thanks guys!

Re: [Elecraft] K3 feature request: Save Menu's states
We originally did this, Bill, but here's the problem. Those new to the K3 sometimes forget that VFO B scrolls the menu entry and VFO A modifies the parameters. If the last-selected menu entry is in effect on power-up, you can inadvertently change something important by spinning VFO A.

Is there somewhere where I might find a more exhaustive step by step discussion of seting up sound levels on the pc while connected to the K3... Not that I am aware of. Best to learn by doing. Put the radio in TX TEST mode and play with the LINE IN GAIN and the PC soundcard program. Don't get too worried about the ALC bars. 4 or 5 bars is fine. In some cases the bars fluctuate a bit.

Re: [Elecraft] K3 and PSK
Robert, I don't know of any step-by-step instructions, the whole picture is complicated because of the variety of computer soundcards that could be used. As far as the K3 is concerned, the procedure is simple - adjust the line-in gain setting, much as you would with the mic gain. Yes, the level can be set using TX TEST - and it is best if you do it that way because you don't both other hams with on-the-air signals. Normally there are two controls to work with - the LINE gain setting in the K3 and the Line-out soundcard controls on your PC. The output from soundcards vary, so you will just have to manipulate them and see what happens. For starters, I would suggest setting the soundcard line-out level at the slider midpoint, then adjust the LINE gain setting on the K3. You should strive for settings that will allow you some later adjustment room if possible, but if your soundcard output level is very low or very high, that may not be possible. You want to have a maximum of 4 bars of the ALC meter illuminated. 5 bars is where the 'real' ALC comes into operation, and the bars below the 5th act more like as a 'VU meter'. You want the level as high as possible without actually driving it into the ALC region (5th bar).

Re: [Elecraft] Need Help with XG1
Wow, Pete, what a puzzle! You might make up a little probe consisting of a wire connected to your rx antenna input that you can touch to the circuit parts. If it has to be a long lead, use a bit of coax so random signal pickup won't confuse things. If your rx input is grounded for d-c, put a small cap in series - anything from .001 to .1 should be FB - to provide d-c isolation. Then touch it to the collector of Q1. You should find your S-9 signal. If not remove coupling cap C4 and try again. If you now have signal, there's a ground somewhere in the attenuator that is killing the signal. If not, you have a defective transistor (although that is high unlikely given that you've established that the voltage on the collector is correct.) Once you have the signal at the collector, start working through the attenuator until you lose it.

Re: [Elecraft] Upgrade question
These are inexpensive and effective desoldering tools, but be aware they are *not* temperature controlled. The tip temperature can soar to well over 800F, especially while sitting on the cradle, then drop too low if you are removing parts from board that includes a fair-sized ground plane. Such heat extremes - too high or so low the iron is on the board too long - can easily debond (lift) circuit traces and do other nasty stuff. That's why Elecraft calls for a temperature-controlled iron in all the manuals and mod instructions. It's the temperature control that causes most of the price difference.

It really would be impossible to do this because the output level and input sensitivity of different sound cards will vary. The output even varies from one program to another. The receive side is easy enough, and can be adjusted until you see a faint moving background on the waterfall with a quiet band, and the signals stand out clear. On transmit I would suggest that you just increase the audio going in to the radio using a combination of the slider on the PC mixer and the MIC control, until the output on the power meter reads the power you want. Ideally you should do this while getting the software to send a Tune signal - a pure tone, and aim for 50W or less. A modulated PSK signal should give a reading of less than half the peak power, so no more than three bars on the power scale. I'm unhappy with the advice to set the level to 4 or 5 bars on the ALC scale because when I do this my K3 puts out twice the power set on the POWER control making it far too easy to overdrive the PA. I prefer to adjust the input level until the output power matches what it says on the power control. Then I can use the power control intuitively to set the power the same way it works in CW and SSB modes.

[Elecraft] Impossible mission? USB with the 13khz filter for PSK31 on Digipan
Hi there, I am running my K3 with Digipan computer software on PSK 31. I also have a full complement of 5 filters in the K3, with the widest being the KFL3B-FM 13Khz filter. Because Digipan can receive many PSK signals at once (Multichannel Window), I would like to set my K3 to receive USB through the 13Khz filter. Unfortunately, despite specifically enabling the KFL3B-FM 13Khz filter in USB mode, I cannot get 13Khz of bandwidth in USB receive. As a matter of fact, I cannot seem to get much more then 4Khz of receive in USB receive mode. I can get the XFIL display to tell me I am receiving through the 13Khz filter, but only about 4Khz of audio will pass through (perhaps the DSP??). Am I missing something here, or is this just an oversight in firmware design? Multichannel simultaneous receive of a massive chunk of bandwidth is a great feature of Digipan that I would love to take advantage of with my K3.

Many of the older digimode programs use a sampling rate of 8KHz or 11.025KHz. So my first question is what sampling rate are you using?

Still, I can only get about 4Khz out of the K3 even though I have the 12Khz filter, and I wouldn't be surprised to find other software out there that will go much wider. My second question is, what is the point anyway? All the PSK31 activity here takes place in a bandwidth of about 3KHz. I guess a lot of the time that is true, but certainly during the PSK 31 contests things broaden out a bit. So a 4KHz waterfall would show you all you wanted to see. If it covered any wider then stations operating close together would be hard to tell apart. I don't understand what you mean by that. Why would they be harder to tell apart if I had more bandwidth? I don't want to run broadbandwidth all the time, just long enough to find somthing interesting and then I want to narrow down to 50Khz (I also have the 200hz filter) to peak it up. Actually, that brings up another point, I wish the filter shift would move in increments smaller than the current increment so that I could really zero in on psk31 signals, as they are so close sometimes, and I like to operate in the smallest bandwidth possible.

For me, the amount of input needed to do this is some way below the point at which ANY ALC blobs appear. If you really must do this, you should probably set CONFIG:TX ALC OFF once you've adjusted your power level using the PWR control. Otherwise the ALC system will see the Tx output not being what was requested and will increase the gain, leading to power creep and all sorts of other problems. And a side effect is that when you next request power, you'll get alot more than you asked for because the ALC loop now believes the Tx chain gain is far less than it actually is. The ALC 5 bar level is the level to which all transmit system gains are balanced -- at least those that use any sort of audio as the ultimate source. In the latest Beta code I tried very hard to balance levels so that CONFIG:TXG VCE can be set to 0.0dB. This might have been affecting your power control issues. I did extensive testing with Olivia (125/8 through 2000/64) and WSPR to be sure the power levels are as requested and stable.

Re: [Elecraft] Upgrade question
All, Believe it or not, I already own both of the RS items. I abandon the desoldering iron because of the temperature issue Ron mentioned. I feel that the sucker doesn't really cut it as far as vacuum power. I was planning on using my Weller WES50 station and the trusty old Sold-a-pult. I guess I panic whenever there is a chance the a board could get destroyed. It seems the consensus is that the rock-and-pull method should work without a problem assuming the temperature is kept low enough. I guess the next logical question would be, What's the difference between the old and new crystals?. Were the older crystals of inferior quality?

Such heat extremes - too high or so low the iron is on the board too long - can easily debond (lift) circuit traces and do other nasty stuff. That's why Elecraft calls for a temperature-controlled iron in all the manuals and mod instructions. It's the temperature control that causes most of the price difference.

[Elecraft] K2 low resistance at pin 8 U6 rf board.
Hello all K2 users. I'm trying to track down a problem on the rf board. Pin 8 of U6 shows a resistance of approx 50 ohm when it's supposed to be greater than 100 ohms. I've gone ahead and assembled the rest of the kit and I am not happy with the amount of current it draws, approx 240 mils. I notice that when listening to WWV at 10 megs if I hit the dit key, the current drops to 160 mils. Anyone else see that? I wonder what part of the circuit is dropped when the key is closed and if it's the 8B line, (where I'm seeing the low resistance.) I know I can use it the way it is but it's really not what I'd like to use if it draws more current than it's supposed to. Don and Gary have offered advice and I wonder if anyone else could shed more light on locating the problem of low resistance. Nothing is getting overly warm, that I can find. Thanks.

Re: [Elecraft] Impossible mission? USB with the 13khz filter for PSK31on Digipan
The K3 audio channel is designed for communications audio in a bandwidth of 5 kHz or less. There are a number of reasons for this. Using the 13 kHz roofing filter doesn't change that. It does widen the IF passband and make the radio more susceptible to nearby, very strong signals. Think of it as a way to emulate the performance of high-IF radios with wide roofing filters :-) In addition, most PSK31 activity takes place in a 3 kHz or less window on most bands since that is what most SSB filters will pass in most radios. I almost always narrow the passband once I have a QSO in progress since a strong station coming on can activate the AGC and push down the signal I am trying to copy, or affect the soundcard input, etc. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

CW Skimmer requires separate I/Q sources in order to do broadband decoding and that's not available from the K3 audio interface (Line Out).

Re: [Elecraft] K2 low resistance at pin 8 U6 rf board.
John, 240 ma is quite normal for receive current on a K2. However, I just measured the resistance from RF board U6 to ground on 2 K2s and found the normal resistance is about 240 ohms. I also tried checking the current draw when the dit key is held down (power set to zero and the keying input set to HAND) - the current increase is a bit over 20 ma., so I can't explain why you are seeing only 160 ma - unless your keying input is set to paddles, and then it is possible that the changing display numbers are not settling fast enough to give you a valid reading. 73, Don W3FPR John wrote: Hello all K2 users.

Re: [Elecraft] PowerSDR-IF
Sam, I am not using a Softrock with the K2, but the principle is the same as that indicated in the article you referenced. The K2 IF center is close to 4913 kHz, but will vary from K2 to K2, and the CW center frequency will be different than the SSB filter center. Your softrock receiver will have its own center frequency. So do exactly as the article says - subtract them and enter that into PowerSDR as your initial trial. That will get something on the screen at approximately the frequency indicated by PowerSDR. That can be refined by using a signal of known frequency. 73, Don W3FPR Sam Morgan wrote: Here is my question: If anyone is using this PowerSDR-IF software with a Softrock as an IF for a K2..

Re: [Elecraft] K3, Mixw, Rigexpert, and Vista problem
Hello Ken, If your using rigexpert with the mixw software you have to set the soundcard to rigexpert first. then when you go to cat interface it will show the rig expert. I had it working great. I now use a Navigator interface. But the rigexpert was all I needed.. Don...w2xb Kenneth Waites wrote: I'm trying to get things going on VISTA. I downloaded the VISTA version of the RE and MIXW driver. I used VISTA Device Manager to set USB Serial port to be 13, 4800 baud. I used MIXW to set Kenwood, K2 model, com 13, 4800 baud. When I bring up MIXW I get message indicating com13 is already in use. Has anyone gone thru this?

[Elecraft] K2 freq calibration...
I am having a hard time getting the frequency calibration on my K2 closer than 80 Hz. I set the osc to exactly 4Mhz, plus or minus a Hz on the pro3 switching between usb and lsb, it also agrees with the HP spectrum analyzer, I then run the cal pll, and the bfo calibration, and when tuning in ssb signals, they sound normal 80 or more Hz higher than they should (as tuned in on the pro 3). Is this as good as it gets on ssb? I have compared CW signals between the two rigs and they are very close, within about 10 Hz on 80 meters anyway. It seems the freq counter, pll cal, and bfo all sort of interact, but if the freq counter calibration is spot on, why the 80 Hz difference? (80 Hz is as close as I have gotten it in many attempts) Also, is it normal for the non ssb filters to look SO bad on spectrogram?? I got the ssb option on Tuesday, it was done Tuesday night, the antenna tuner was done Wednesday, no problems with them, no missing parts, no issues, I made my first ssb contact yesterday on 80 meters using the hand mic from the pro 3. SSB from the K2 sounds good in the pro 3, the report I got said it sounded a bit restricted, the hand mic sounds poor on the pro 3... What would be a nice sounding microphone to use with the K2? Also, I have been thinking of taking down the home made G5RV and trying an alpha delta dx-lb plus (160 through 10), the G5RV does not seem to work as good as the 40 meter dipole on 40, and its likely worse on other bands... Anyone got anything bad to say about the dx-lb plus, I know its not as good as a full size 160 m antenna, but I have about 110 feet max between trees. I sure am enjoying the K2!

Re: [Elecraft] K2 freq calibration...
Brett, You ask several questions, and I will delay on all of them except the one about calibration. You are relying on too many variables when setting the 4 MHz reference oscillator. To reduce those variables, use the N6KR method that is documented at http://www.elecraft.com/Apps/K2%20C22%20Adjust%20App%20Note.pdf. If you can tune WWV accurately, all other variables are cancelled out by that method. You may also find helpful information in the K2 Dial Calibration article on my website www.w3fpr.com. For your restriceted SSB audio, consider the comments in that article about the low frequency corner of the SSB filter passband carefully - 300 Hz is the 'magic' frequency. After you get the dial calibration correct (within 20 Hz or less), ask about the other items. 73, Don W3FPR Brett Gazdzinski wrote: I am having a hard time getting the frequency calibration on my K2 closer than 80 Hz.

[Elecraft] K3 and Windows 7
Took a bit of fiddling to get LP_Bridge to create virtual com ports, but everything is now working with Windows 7. LP_Bridge sees the K3. PowerSDR works with my 0202 USB Sound card. HDR connects too. The K3 utility works as I was able to backup my K3. The first two installations of Windows 7 failed with a blue screen at the final reboot. It turns out the two USB to serial interface drivers were hanging things up. I simply unplugged the hardware, did the install, then plugged them back in. They run fine now. Not sure why they hosed the install?? I guess the install doesn't like the drivers, but Windows 7 has no problem after it's running. I can't say exactly what was hanging up LP_Bridge the first few times I installed it. On about the third install I tried installing it to 'My Documents' rather than 'Program Files'. Worked fine then. Vista has new security models for the 'Program Files' DIR which is what I suspect to be causing the issues. However, after the successful install to the 'My Docs' I was able to uninstall and reinstall to the 'Program Files' DIR. Go figure.

[Elecraft] Watt Meter Behavior
My watt meter seems to behave strangely in SSB. I've run all the calibrations and have it hooked to the Elecraft W1 watt meter and 50 ohm dummy load. When set for 100 watts, I get 100 watts on both the K3 and the W1 on CW key down. On SSB, the K3 meter regularly exceeds 100 watts, pegging the 120 lines while the W1 peaks out at 100 watts. I've noticed this for several revision of firmware. I also just downloaded verson 2.8 and tried setting the SMTR PK to ON, but the peak reading doesn't seem to work anymore. Anyone else have this experience?

Re: [Elecraft] K3, Mixw, Rigexpert, and Vista prob
The problem was a mixture of two versions of mixw. Now the only thing I still have to get working is the PTT so ESC key will toggle between TX and RX, I have it set up in the cat interface, but so far its not working. Now I think I may have to change something in the K3 PTT config items. Ken K5WK___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
