[Elecraft] Calling CQ on PSK-31
This is pure speculation. I've observed the same thing running QRP on digital modes. I believe it could be a simple matter of the QRP signals being less bright on the typical waterfall compared to someone running 30-50 watts, and it's probably only natural that someone looking for a QSO will click on the brighter signals. Even though copy may be 100% on the dimmer trace, folks wanting a solid connection will gravitate to the bright traces. There is probably no way to confirm this, but I also have had better luck responding to someone else's CQ, and usually they have no problem with my signal.

Re: [Elecraft] BL-2 Balun Heating
Thanks to everyone that replied to my situation. Looks like I'll be busy doing a lot of testing and experimenting today. I'll get back with the results later. Gary N2UM I hope that will include the suggestion of placing the balun between the rig and tuner, just so you can report back on it. K7EL of EZNEC fame wrote pretty extensively on this several years ago. I've tried it, and it seems to work, but I was never quite comfortable not grounding the tuner (not sure why). But if you look at Palstar's balanced tuner, that's exactly what he does. There are similar balance-L circuits out there, so it's probably worth a try if you don't want to spend a lot of time trying to find a combination of feedline and antenna length that will make your balun happy on several bands. Let us know! 73, Parker WD8JOL K2 #2636 __ 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] Power Required for PSK 31 and Olivia
Hope I can reply from digest mode... From: Frank MacDonell kd8...@gmail.com My K3 works well for CW at 5 watts but it seems I cannot get through to stations using PSK 31. Is there a minimum power level suggested for PSK31? Can you run QRP for Olivia? Thanks everybody! -- Frank KD8FIP I've noticed the same thing (with my K2). I can easily make QRP contacts in CW, but don't have the same result with PSK or Olivia. I fire up an old FT-757 for that purpose and run 30 watts or so, even though PSK is known for its low-power capability. My pure speculation is that the brighter trace from higher power attracts more replies, even though the weaker trace from QRP is perfectly readable.

Re: [Elecraft] Elecraft Digest, Vol 59, Issue 26
I just checked to be surethe sidetone volume is independent of the AF gain. It's adjusted as a menu item. Changing AF gain has no effect on sidetone output. Parker WD8JOL K2 #2636 I don't have my K2 yet?but should have it in about a week..depending on options. I noticed in the schematic that the side-tone output(U10B pre-amp) looks to be connected as a secondary input to AF-amp(U9 LM380). This makes me assume that side-tone volume is not fixed, but instead changes along with, and is a percentage of AF volume. If that is true, its a setup that I don't prefer.

[Elecraft] [K2] VOX on digital modes?
Is there any fundamental reason why I can't use VOX control while running PSK with my K2? I've never used VOX with this rig on SSB, but I assume it works okay.

Parker, The K2 VOX does not work well with PSK - by the time the audio is cranked up enough to trip the VOX reliably, you will be driving the audio input too hard and the transmitted IMD will suffer. The VOX in the K2 works OK for voice, but not as well for the more steady audio tones of soundcard digital modes, so I recommend you stay with the PTT operation - since you apparently already have that working, I see no advantage to change. The K3 VOX OTOH is very smooth and will work quite well for afsk data modes. 73, Don W3FPR Parker Buckley wrote: Is there any fundamental reason why I can't use VOX control while running PSK with my K2?

[Elecraft] Re: Receive Antennas
I was interested to read recent comments on 160M receive antennas. As it happens, I just completed a coaxial loop antenna for my K2 this weekend, as described by KN4LF and KC2TX, and combined it with their recommended preamp. It's the antenna design that's been in the handbook for years. I've wanted to try one of these for some time, thinking I might hear that rare DX that everyone else seems to be working. So it's all tuned up and seems to work well, but let me ask a basic question. If I already enjoy relatively quiet conditions on 160, in spite of living in the city, will the loop ever hear anything that my full-sized inverted L won't hear? The inverted L seems to work well, as I've worked all over the US, including Hawaii, during contests; all the while at 5 watts (I know, it's all about their beverage and not my whopping signal, but still I'm pretty happy for QRP). My nominal noise level on the L is 2 S units. I peaked up the K2 and measured receive sensitivity, and I think it's doing all that it should. So is this loop antenna just a fun project, or will this let me hear things so far down in the noise that I would not other wise hear them?

[Elecraft] PSK31 Power Level
Elecrafters, Don has been coaching me off-list through installation of one of his fixed audio output kits, which I've had around here for many months, un-built. All went well, except the audio through my computer was distorted. I eventually tracked it down to the K2 DSP gains being set too high. I was getting away with that in the basic K2, but the fixed audio unit doesn't like being pushed that hard. I've now carefully reset the DSP gains to get the same audio level with DSP and with DSP bypassed. Everything is working great. I'm now reminded of a nagging question since the last time I strayed from CW to PSK 31. I've read numerous places about setting the power level (mine is a QRP K2) to five watts for continuous use like PSK. Does that mean five watts for single tone like CW, or five watts average as the two tones warble back and forth? I'm using a WM-2 wattmeter in the output. Running about 10 watts single tone, I get about five watts warbling and a single ALC bar flickering. Is this okay, or should I back it down to five watts single tone? I thought this question might be of interest to a wider audience.

[Elecraft] RE: PSK31 Power Level
Don, It's that idle tone that I question. If I push the Tune button (Digipan) I get a single tone. If I push the T/R button, I get a dual warbling tone which gives about half the reading on the wattmeter (probably something like an average of the two warbling tones and some off period between them). So you're saying to bring up the single tone to only five watts? That puts the warbling tone down to the 2-3 watt level. I guess the peaks are probably hitting the five watt level, but the meter can't keep up. Thanks, Parker _ From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Sunday, February 25, 2007 6:23 PM To: Parker Buckley; W3FPR - Don Wilhelm; Elecraft@mailman.qth.net Subject: RE: PSK31 Power Level Parker, The best for running PSK31 is to set the power knob to 10 watts or above. Then adjust the level from your computer soundcard so your power meter goes up to 5 watts with the idle tone. There should be no ALC bars showing. Also, be certain that you have the compression set to 1:1. If you are using the RTTY mode, there is a separate SSBCr setting in the menu, and that is independent of whatever compression level you may be using for SSB. If you are using the RTTY filters, remember that there is yet another set of 4 filters that need to be properly set up for width (use the OP1 filter for FL1 - that is important), and set the remaining filters whereever you would like in terms of width and filter center. Use Spectrogram and it is easy. If you want to increase the gain for the KDSP2 again for whatever reason, you may have to add a divider at the two inputs of the Fixed Audio board - something like 2.2k in series and then 2.2k to ground should give you good results. 73, Don W3FPR -Original Message- Elecrafters, Don has been coaching me off-list through installation of one of his fixed audio output kits, which I've had around here for many months, un-built.

RE: [Elecraft] Tuner/Balun Question
Don, Okay, that's as I suspected. It makes sense to me that the tuner could resonate the antenna-feedline system, but that the currents may remain unbalanced. One of my antennas is a quad fed with open line, and such operation would probably skew the directivity. I think I'll stick with my baluns Thanks, Parker Snip The result is that power may be delivered to the antenna but the feedline will be radiating and the pattern from the antenna is unknown. That's the short answer ... I await the many antenna experts on the list to embellish it.

[Elecraft] Tuner/Balun Question
I just read the Aerials article by Krusty Kurt in the October issue of World Radio. Near the end of the article, Kurt is describing a well known method of running parallel coax through the wall to connect ladder line to the antenna tuner. His method ties the shields together at both ends to get 100 ohm feedline, while I've always left the braids near the ladder line floating. What really caught my attention, however, is his comment that you can run the parallel coax lines straight to the tuner without a balun. I've always used a balun in this setup; either 4:1 or 1:1. I recall emails to this reflector in the past describing connection of ladder line straight to an Elecraft tuner with no problems. I'm now wondering if I could ditch the baluns in my installation. Any thoughts/experience with this? Is the output from a tuner balanced at the coax connector up until such time that it's connected to an unbalanced load like a single coaxial line?

RE: [Elecraft] Tuner efficiency question
Hi guys. I certainly appreciate your quick responses. Like everything else, I guess the answer to a certain extent is It depends. I probably should have sidestepped the balanced tuner vs tuner/balun part of the question. I've tried all kinds of combinations along those lines, probably guided more by practicality for the particular installation than efficiency. So maybe I should have started with Assuming a coax-fed antenna.. It sounds like the decision still comes back to (given a reasonably efficient design), what's most practical for the need. The KAT2 integrates directly into the K2 and the T1 offers flexibility for use with other rigs.

[Elecraft] Tuner efficiency question
I've been using my QRP K2 for the last 2-3 years with a full sized Palstar tuner. I use a variety of antennas from 160 to 10 meters, fed with coax, ladder line, choke baluns, the Elecraft balun, etc. I'm thinking about going to an auto tuner (Dayton Hamvention coming). Has anyone compared the efficiencies of the very small tuner like the T1, the KAT2, and larger tuners like the Palstar? (I've been the Johnson KW Matchbox route as well.) Intuition tells me there is something lost when going to very small components packed into a tiny space compared to large air variables, big roller inductors, etc., but I don't have anything to back up that gut feel.

[Elecraft] N4PY Software
Basic control of the DSP unit with NP4Y software has been available for many months now. Ben, I'm interested in your post about programming the buttons for DSP. I tried that also, but maybe not the same way. I set one button for DISPLAY, and another for BAND+. I then hit them in the sequence you stated. The problem is that without some indication on the computer screen, I can't tell what state the rig is in unless it's close enough to look at. For example, if I hit the BAND+ button first by mistake, then I've just changed bands. Maybe you set up a more foolproof way to do it. As I understand it, Carl is planning to create new buttons to allow direct control of the DSP without a sequence of button pushing as with the basic K2.

[Elecraft] Exciting news from N4PY Software
I recently downloaded N4PY/Carl's Pegasus control program which he's configured to work with the K2. I asked him if he planned to incorporate controls for the KDSP2 in it. Turns out he doesn't have DSP in his K2, so he asked me some pertinent questions. Now, he's decided to go ahead and install a KDSP2 and begin programming to support it. He plans to first develop the basic control functions, then perhaps code up a SETTINGS menu to allow all the various parameters to be input from a PC. I thought many of you might be interested in this development. As the K2 adds more and more functions to the existing buttons, it seems to me that setting up the radio (including the clock!) from a PC would be extremely useful.

I've also experimented with a variety of wire antennas, including center fed zepps, dipoles, vertical dipoles fed with ladder line, verticals with elevated radials, verticals with loaded elevated radials (as in Moxon), and consistently the ground mounted vertical monopole is quieter (and provides at least the same signal strength).I've also tried a simple monopole for 30 meters (made from HF-2V parts) mounted on the same ground system, and found it to be quieter than any of the wire antennas on 30, either vertical or horizontal. I believe the ground system is key to the whole thing.the ground mounted vertical is simply quieter than elevated ones. If you can install a decent set of radials (quite easy to do: mow the grass, stake the wires out, and let Mother Nature hide them for you; at least it works in Ohio), I think a vertical is worth considering. I've done extensive EZNEC modelling of all these antennas, and while interesting and fun, the noise issue is hard to predict and can be one of the more important considerations.

Re: [Elecraft] Re: More antenna problems
Earl, I agree that's what the model shows and what the theory says. You're probably assuming the dipole is at least a half wave above ground, which can be a challenge at lower frequencies. I'm just relating my real world experiences, and suggesting that the vertical not be dismissed too soon in the considerations. Would love to continue, but I'm heading out on a trip. Looking forward to checking back in when I return! 73, Parker WD8JOL - Original Message - From: Earl W Cunningham [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; elecraft@mailman.qth.net Sent: Wednesday, July 28, 2004 1:01 PM Subject: Re: [Elecraft] Re: More antenna problems George, W5YR writes: Parker, what did you think of the EZNEC gain predictions for verticals? Compared to wire dipoles at a modest height? == The free space gain of a vertical is about the same as that of a dipole (2.14 dBi). However, over real ground the horizontal antenna benefits by far field ground reflection. This is borne out in EZNEC. Remember that a vertical's gain is concentrated at the low angles that are good for DXing, while the horizontal antenna must be relatively high (at least 0.5 wavelengths) to have a reasonably low angle of radiation.. As far as noise goes, the dipole has a better receive S/N ratio than a vertical simply because it has directivity, while the vertical is omnidirectional. Also, because of its low angle radiation, the vertical hears man made noises better (which are generated close to the ground and therefore arrive at a low angle). 73, de Earl, K6SE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
