Re: [Elecraft] First test of LP-Pan on K3 with emu0202
Update to my earlier e-mail: The emu soundcard was apparently uninstalled by my computer (when I turned off power on the soundcard). After a couple hours I came back to make more tests and found it non-functional; it was no longer listed as hardware in the computer. Drivers were gone. So I decided to re-install it, but this time I disabled the embedded soundcard on the mother board. Install went well (in fact better as the first time I installed it halted during the install - but gave me instructions to restart the computer typical for installing drivers). Well, this time it now plays with a flat spectrum and appears to have more gain with signals from the K3+LP-Pan. Overall the display and function seems more "normal" compared to how the SDR-IQ runs on this sw (Spectravue). Noise floor (antenna connected) is still running -62 dBm vs -106 dBm for the SDR-IQ. Maybe a difference in gain between the two receivers, or the sw reacts differently on the two receivers? Going to write Larry at Telepost for his opinion as the K3+LP-Pan+emu0202 is a standard set up. I compared the two LP-Pan units and one seems to have a few dB more output but not a significant amount. The next step is to install the Delta-44 4-port soundcard (requires opening the computer to install the PCI card). The Delta-44 handles four audio inputs (two I/Q pair per LP-Pan) needed for running diversity SDR from both main-Rx and sub-Rx (which will require surgery for breaking out the IF). The Delta can be run with the same IF coupled to both LP-Pan for testing. That will leave surgery as the last step in my project. http://www.kl7uw.com/LINRAD.htm 73, Ed >Date: Sun, 30 Jan 2011 17:38:22 -0900 >To: Moon-Net >From: "Edward R.

Re: [Elecraft] K2 and WINMOR
I'm using RMS Express on a K3 with up to date firmware. There are also issues with K3's, where the AP performs a bunch of serial commands that cause a 300-500 mS delay (probably a band change as seen by the K3). So the first TX begins before the last command is processed, and only the trailing edge of the audio-in is sent. The next TX is fine, so are others following. For the K3, you just lose the first one. It could be that this same problem with the AP causes a different reaction on the K2 (haven't checked mine yet). For my MARS RMS Winmor node, I have it set up to use VOX. The rig is a JRC JST245 (rather dated, but good reliability) that only supports 4800 BPS on the serial port. This allows frequency control, but isn't fast enough to use for TX. If you have a complaint about any of the supported radios in RMS Winmor, better address them to Rick Muething soon. He's off on other projects now, and it's not clear if that group has any sustaining staff. For the K2, I'd just use DTR or RTS as a hard-keying line to the PTT. You might have to put a 2N390x or some other switch transistor in the PTT path to handle any inversion and drive. 73, matt W6NIA / NNN0UET On Thu, 27 Jan 2011 16:51:29 -0800, you wrote: >Is anybody running WINMOR with a K2 and SignaLink?

[Elecraft] K3 APF Problem
Vic and all, This morning I've reloaded all the K3 firmware and the problem has disappeared. Guess the third time loading is the charm. Two suggestions for those that make decisions. Put a feature in the utility to load only certain firmware rather than a complete reload. There is a feature to upload only new revisions but nothing to reload only a single firmware. Second, zip a complete set of compatible firmware files into one file, unzip it in the utility and load from those files only. This could eliminate the problem I had that took several emails and three days to correct. Of course, individual files could be left on the server for those desiring to download individual files. The APF does give a peak to weaker CW so it is a definite improvement. I noticed very little ringing. It makes the audio sound a bit more crisp making it easier to hear. Guess that is a result of enhancing the "Q" someplace as has been previously discussed. Vic, thank you for helping resolve the problem with my K3.

If you enable advanced mode in the utility preferences, you can chose to only load specific files. Be careful with this, as DSP, CPU, FPF files etc from a release must all match the release set.

Re: [Elecraft] Take the plung!
I made about 380 Qs in the 160 meter test and worked some at the superstition level, a couple I used the APF on, several who were no doubt QRPers. I never heard anyone sign /QRP. So this may be one of those things to be indignant about that has little basis in reality. If someone had signed /QRP, I wouldn't have felt greatly harmed. I worked other stations who took longer than typical to work due to being unfamiliar with contest procedures, etc. I was still happy to get 'em into the log. 73/72- Nick, WA5BDU __ 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] Zero Beat
Now that we have such great filters in the K3, we have another problem: Many other operators just can't find the right frequency. Not only do the stations calling you often miss your passband, those calling adjacent stations DO end up in your passband. We have our CWT, but what we really need is a feature which gets the OTHER station on frequency. Now, I understand that this is technically challenging, but that's just the sort of thing the folks at Elecraft are so good at. Meanwhile, I guess we'll just have to hope that more of those operators buy K3's. 73, Scott K9MA Scott Ellington Madison, Wisconsin USA __ 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] P3 Temperature Specs
Hi all, I recently set up my K3/P3 combination on my workbench in my garage in order to do some rig comparisons, etc. The garage is not insulated, and here in the desert it can get pretty chilly at night. Several nights have been slightly below freezing outside, and inside the garage it can get down into the mid 30's, or slightly higher. Anyway, I began noticing, on these colder nights, that my P3 didn't want to "wake up" for a while. It would just show "0" for operating frequency, and the display was not effective. Cycling the P3 on and off didn't seem to accomplish anything, at least for a while. Eventually it would wake up, presumably after just a little internal heat was generated. I'm pretty sure this is just a temperature thing, since I never have the problem if temperatures are more reasonable. I looked on the Elecraft website, but didn't find any "specs" for operating temperature. I'm just wondering if these were ever evaluated. The K3 doesn't seem to have a problem--just the P3.

Re: [Elecraft] Zero Beat
No, no. That kind of tracking I can do with the RIT, but on a crowded band there's an excellent chance that there are lots of other loud signals on either side of that little 400 Hz slot I've chosen. We need a K3 feature that grabs the VFO of a station halfway around the world and zero-beats MY K3. (Only when he's calling me, of course.) I didn't say this would be easy. Maybe W0EB's "zero-beat monkey" is the solution, after all. 73, Scott K9MA On Jan 31, 2011, at 12:59 PM, Geoffrey Mackenzie-Kennedy wrote: > Some form of Tracking Filter?

[Elecraft] K3 Spot Tone Level
The K3 "Spot" tone level apparently tracks the "Monitor" sidetone level. I like to keep the sidetone level as low as possible to minimize fatigue, but at that level the Spot tone is inaudible. If I haven't just been transmitting, I lose track of just where the sidetone was, so the Spot tone would help me zero-beat accurately. Anyone else have that problem? (CWT isn't useful if there are multiple signals in the passband, as there usually are in contests.) 73, Scott Scott Ellington Madison, Wisconsin USA __ 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] Take the plung!
Brendan, I agree with you entirely regarding the appendage /QRP. It is a pain in the ass and I do not like needing to add it to my log. If I go QRP and I am thinking of it the difference is that I have good antennas. Some less fortunate hams are very limited in their antennas and operate higher power levels to compensate. Maybe there should be another class called "QRP and a hank of wire ten feet of the deck". QRP is good but signing /QRP is not. QRP is a great area for Home Brewing and wonderful for portable work. I am not anti-QRP but hate the appendage! For that matter if I am going to be a real old man, I do not care for special call signs that are artificially constructed. 73 Doug EI1MORSE / EI2CN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Brendan Minish Sent: 31 January 2011 18:59 To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Take the plung!

Your change would force excess keystrokes (or knob twisting) vs. the current condition. You save one keypress (tap A>B) to synchronize VFOs when initially selecting split but cause synchronization of the VFOs every time Split is turned On/Off which results in any previously set split when for example checking another frequency/pile-up/band.

Re: [Elecraft] P3 Temperature Specs
Most LCDs will freeze and self-destruct by cracking the screen, although that normally takes temperatures below zero F. However, most of them are specified to work properly only at much warmer temperatures - between about 50F and perhaps 100F. Also, many manufacturers recommend allowing the LCD to warm up naturally before applying power if they have been stored at very low temperatures.

The "operating ambient temperature" spec for the display used in the P3 is -20 to +70 deg C (-4 to +158 deg F). Is the problem in the P3 or the K3? If you let the K3 warm up for a long time then does it work right away when the P3 is turned on? And vice versa, if you let the P3 warm up first, does it work as soon as the K3 is turned on?

Re: [Elecraft] K3 - psk31 - HRD
Roger, Set the soundcard output higher. Note -- if you have more than one sound card, the normal volume settings displayed apply only to the default soundcard. You must use the Control Panel to temporarily change the default soundcard to adjust the controls on the other one, and then change the default back. There is nothing wrong with using a higher level out of the soundcard. Set it up to at least 75% or even at the 90% level (more if you need it). You need to achieve 4 bars solid on the K3 ALC meter, or you will experience "power creep" in the K3 output. You adjust the K3 LINE-IN level, not the mic level if you are connected to the line-in jack. Set the selection to be used in data mode in the K3 menu. If you have an interface box in between the computer and the K3, that may be your problem source. Many interface boxes reduce the signal from line level to a microphone level. Give us more details about your setup and connections if you continue to have problems. 73, Don W3FPR On 1/31/2011 11:09 AM, roger shirko wrote: > here's the setup: > > windows 7 -- HRD / DM 780 5.0 build 2636 -- K3 most current software and > direct > connect to PC sound card and using Elecraft USB/Serial cable.. > > everything in HRD is fine with the K3 .. am able to completely control all. > > DM 780 waterfalls work fine, so comms between K3& software is functioning. > PTT configured for HRD > > > > I used the Elecraft Op Tips (Mar 2, 08) and attempted to follow it. > > I can set the K3 to DATA A - no problem > > Cannot get any bars on the ALC, no matter how I adjust MIC - sound card is set > to midpoint on both in and out > Cannot get an XMIT indicator but works in PSK D with the morse key > > __ 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] Take the plung!
Doug, I couldn't have said it better myself. QRP is good, signing "/QRP" waists information bandwidth. Also when it ends up either in or not in my log and the Qs are uploaded to eQSL, the callsigns don't match and I have to manually generate a QSL (which I do gladly). It does have to be manual after all. Right now I have about 130K QSOs on eQSL. I don't chase their awards but every QSO I have is uploaded for those who do.

Re: [Elecraft] K3 Spot Tone Level
These two sounds are intended for two entirely different psychoacoustic tasks. The spot function involves perception of the pitch of the tone. The monitor function involves merely hearing the presence of the tone, and intervals of absence of the tone. The effectiveness of these sounds is different as their respective volume changes. If precisely the same loudness works equally for both, it is probably a fortunate coincidence. There is every reason to provide two separate volume controls. and no useful reason for them to be adjusted by a single volume control.

Re: [Elecraft] K3 - psk31 - HRD
Hi, You don't have to change the default sound card setting if you want to set the volume of one that is not the default. Once you have the volume setting for the default card displayed, click "options", then "properties" and you will get a dropdown list with all the installed "mixer devices" and you can select the one you wish to change the volume for. With Vista and Win7 the nomenclature may be a little different from what I have described, but should follow the same general guidelines. In my view, for amateur radio use, there are still good reasons to stick with XP. AB2TC - Knut Don Wilhelm-4 wrote: > > Roger, > > Set the soundcard output higher.

Re: [Elecraft] K3 Spot Tone Level
Richard, While "common logic" will say to adjust the spot volume to match the AF gain level of the signal to be spotted, that is too much trouble and involves a lot of "button pushing and knob twiddling". A simpler solution is to just adjust the AF Gain control to bring the signal down to the spot tone level. That works no matter where the spot/sidetone level may be set. Try it, it works and is a lot faster than trying to change the spot/sidetone level. 73, Don W3FPR On 1/31/2011 6:45 PM, Richard wrote: > These two sounds are intended for two entirely different psychoacoustic > tasks.

Re: [Elecraft] Zero Beat
Dale, Let's face reality. Only 35% of the hams on the air know how to zero-beat (maybe it is 20%, I have not taken a poll). They just trust that their transceivers will do the job for them - if they can hear the other signal, then they assume they will transmit on their frequency - without regard to how far off the center frequency they may be. I have had K2s here for repair where the operator said he wanted a 750 Hz sidetone pitch, but I discover that he has the ST P parameter set for the default of 600 Hz, That is an automatic 150 Hz misalignment of the received pitch and the transmitter offset. Tell you K1, K2, K3 the sidetone pitch that you prefer to listen to, and set the menu for that same sidetone pitch. Those transceivers (and many others) will offset the transmit frequency by the frequency that you have set in the menu. So the remaining problem is to tune the desired signal in at your chosen sidetone pitch - some do that well, and some do that poorly. We have lost a lot in moving from separate transmitters and receivers to transceivers. Sure the Transceiver can do it "automagically", but it all depends on the parameters you have set into the transceiver. Yes, I have even heard some "old-timers" who knew quite well how to zero-beat using separate transmitters and receivers that have become confused with the concept of zero-beating when using a transceiver. That is just sad to me, but has to be dealt with as a "fact of life". Know your transceiver and know your operating conditions, and set things up accordingly -- in other words RTFM. 73, Don W3FPR On 1/31/2011 7:07 PM, Dale Putnam wrote: > I wonder, wouldn't pass band tuning do well at that too?

Re: [Elecraft] K3 at VP8ORK
They had good signals on 10 and 12M today at the same time around 1530-1630Z here in NY. Only band I haven't heard (worked) them yet is 160M. Sure wish I had a bigger lot so I could have some beverages. Trying real hard to hear them with a pennant antenna on topband. By the way they seem to have real good ears. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of ab2tc Sent: Monday, January 31, 2011 6:31 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 at VP8ORK Hi, I did notice that, but as a whole this expedition so far has been a disappointment with barely a pip heard here.

Have you ever been on a DX trip to a difficult location? Take a look at a map -- the South Orkney Islands are not easy (or cheap) to get to. These are top-flight operators and engineers, most with considerable experience on trips. For whatever reason, they are traveling light. Several good reasons include the cost of petrol and generators big enough to run several rigs and power amps. Another is the cost of dragging stuff there, and what boats you can get to take you there. Here's a simple equation -- a 500W amp makes them one S-unit stronger, but it increases the volume of gasoline used by a factor of 5. A kW amp increases it by 10. If you can use half as much gas, you can stay longer before you run out. > I see they do run some power so that > should not be the problem. Propagation has been disappointing the last > couple of weeks. YMMV. When they first came on the air, NI6T told me they were on 30M, not loud but workable. I fired up the rig, noted them spotted on 40 CW, heard them very well, and worked them within a few minutes. Then I headed up to 30M, where they were busily running a pile to EU and NA. I didn't raise them, but I sure could hear them. 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

[Elecraft] K2 and PSK-31 on iPAD - Alpha demo
Folks, A bit OT, but worth mention on this list. Kristen K6WX wrote an iPAD app for PSK-31 and made contact with a station in TX over the weekend to prove out her app via a K2.

[Elecraft] [K3] KAT3 Hiccup
The CQ 160M CW contest last weekend was the first contest for my K3 SN 4518. First time I've heard the fans kick in, same for the Samlex PS. And I have to say I am very pleased with the receive performance - with filter bandwidth set to 200 HZ and fine tuning, the band didn't seem crowded at all. Very few times did I have any trouble with adjacent signals. But I did have one scare. The KAT3 has always auto tuned my OCF dipole to a reasonable match. But about 7 hours into the contest I experienced a pop in the earphones and the K3 went deaf. The SWR was high and the KAT3 wouldn't tune better than 5.3:1. Thinking maybe I lost a leg off the dipole, I went outside and checked the antenna. All looked OK. I tested the antenna with another rig and a manual tuner and it seemed OK. Not knowing what else to do, I checked the OCF dipole on several other bands with the K3, and the KAT3 tuned to a good match. Then when I went back to check 160, all was well again. Needless to say, I was relieved. Went back to the contest and had no more problems. Anyone else ever experience anything like this? 73, Glenn / KD0Q __ 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] Low output from 2nd crystal filter and SA602 product detector
I am finishing (wishful thinking) a revision A K2 for a friend who bought the kit many years ago and did not build it before having a stroke. I have installed all mods published on the Elecraft site, plus the Rework Eliminators. There are no options right now (but they are built). The filter crystals are the 14 matched ones for a K2 with SSB. I am doing the voltage checks in the receiver. Everything seemed fine until I reach the 2nd crystal filter output and the product detector output. I measure about .150Vrms (expect .270Vrms) at U11 pin1. The output from the SA602 mixer at U11 pin5 is only .060Vrms (expect .580). I guess if the input signal to the mixer is low, then the output will be low. Both of these voltage measurements are very subjective, because they change very dramatically if I adjust the signal generator (an HP 8640B) or the K2 VFO a minor amount. But even doing that, I cannot get the mixer output above .250Vrms. What I don't understand is how the rms voltage output of the 2nd crystal filter (expected .27V) can be expected to be higher than the input voltage (.15V)? Is there some amplification going on here? Am I off in the weeds here? How do I troubleshoot the 2nd crystal filter? Also, the T7 step-up ratio I measured to be 3.65 but the expected ratio is 3.88. (I don't have the D40 and D41 limiting diodes installed.) Is 3.88 good enough? I have tried pushing the windings around but 3.65 is the best I can get. My RF voltage measurements are done using a Fluke RF probe and an HP multimeter.
