[Elecraft] K144XV K3
I installed the K144XV module in my K3/100 last evening and checked it over this morning. With 1 mW showing on the front panel, my SX-600 shows 9 W out into my TE Systems 1452G. This is a nominal figure, probably good to ~10%. The installation goes fairly easily...but boy are there lots of screws! The installation manual needs to be updated in a few places, but is clear enough. The one minor problem I had was with the connection of the TMP cables...the connectors are quite stiff and things have to be aligned very carefully for the plugs to go in. The cable to IF out from the KXV3A is perhaps 1/4 too short. It makes a bend at the K144XV end, and it is a little problematic to get it aligned with the jack. I found a 5 hemostat to be very helpful, particularly on this one connection; my pudgy fingers just didn't fit into the limited space available. Needles to say, I continue to be very pleased with the K3. This is the first time I've had the cover off, and I was surprised to find the box to be quite empty inside. Aren't SM components wonderful! To an old geezer like me, the density is quite astonishing. I look forward to the end of January, when the rig will get its first real work-out.

If you have the 6-kHz filter installed, you can increase the effectiveness of the DSP NB with some kinds of noise in SSB mode; just set WIDTH above 2.8 kHz so this wider filter will be selected.

Re: [Elecraft] [K3] Ameritron RCS-12
Mike, Yes, the KRC2 uses only the AUXBUS signal to obtain the band data. The output of the KRC2 is that a single band is selected. Actually there are 2 outputs for each band - one is referred to as the low side and the other as high side The low side drivers ground the selected band while the high side drivers can source voltage to the external relays. If the relays operate by shorting the wire back to the operating position to ground, then you would use the low side outputs. If your relays require that you supply the operating voltage from the operating position, then you would use the high side outputs. The voltage can be up to 50 volts, but must be positive. The KRC2 is quite a versatile little box. 73, Don W3FPR On 12/15/2010 3:51 PM, Mike wrote: A suggestion was made that a KRC2 would be a better choice than the RCS-12, and that it would drive the RatPack directly.

[Elecraft] Calibration
I just completed the RF Gain and S-Meter calibration on my K3 (4521) and all went smooth. However I am left with a question (of course!). If I leave SMTR MD in NOR, changing PRE or ATT, the affect will be seen on the S-Meter. If I leave SMTR MD in ABS, the S-Meter does not respond to any change in PRE or ATT. What is the advantage of leaving SMTR MD set to ABS since I would guess it would be meaningful to the operator to actually see the effects of using PRE and/or ATT?

Re: [Elecraft] Calibration
If the intent of the S-meter is to give an indication of the signal level at the antenna spigot, then having the indication change when the attenuator and/or preamp is engaged is counterproductive. A 50 uV (or whatever) signal should give the same reading no matter what. In that case, ABS is the answer.

Re: [Elecraft] Calibration
Some people want to see the S meter move with PRE and ATT. Others think that the signal level at the antenna connector is what is important, and PRE and ATT have no effect on that. Looking at it another way, if S9 = 50 uV into 50 ohms, and if I apply a 50 uV signal to my K3, the S Meter should read S9 regardless of PRE or ATT settings (ABS mode). Take your pick :-) 73, Lyle KK7P (who only uses ABS mode) ...TR MD in ABS, the S-Meter does not respond to any change in PRE or ATT. __ 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] Calibration
Setting PRE or ATT causing the S-meter go up and down is how analog radios have worked forever. The S meter was reading the voltage off the AGC bus which usually controlled the gain of half a dozen tube stages. Some folks WANT their digital radio to behave like their previous analog radios and view every divergent behavior as something potentially wrong with their K3. They'll take the better performance, but they don't want to learn a new paradigm to use it. Hence a lot of dual personality items in the K3. But having the input absolute is indeed useful. In this mode PRE and ATT are just a range switch for RF gain. Like LOW, MED and HIGH. Using ABS and calibrated, seeing a 40 over S9 indication (five MILLIVOLTS or more) on an Italian 40 meter ham signal tells me something. Like should I REALLY bother trying to override him, or is he going to SO LOUD in EU, I might as well go find another run frequency. 73, Guy.

Jim, Nothing wrong with your grammar, but the site calls itself Antennex, so you have to put in their spelling whether right or wrong. 73, Don W3FPR On 12/15/2010 7:50 PM, Jim Cox wrote: Unless my grammar fails me, Antenna is the correct spelling..

[Elecraft] Audio Nulling in my K3 in Diversity
Hi All, For the last few weeks I have used the Diversity on the low bands with good success. Tonight I came into the shack and found my K3 acting strange. While in diversity, 4SQ hooked to main RX antenna port and Beverages hook to AUX port, the same configuration I had for weeks. As I tune the band, the audio nulls out about every 0.5KHz where the audio gets very low. The S meter seems unchanged, only the audio is affected. I switched back to Normal receive and sounds fine. Then back into Diversity and I get this nulling of the audio again. Sounds as if a Auto notch was enabled, buts its OFF. The radio has been left for three weeks continuously. I recycled power without change. I am running the latest MCU 4.22 / DSP 2.70 / FPF 1.14, 11-15-2010 I could speculate what it might but I bet this has been seen before. Maybe a operator thing but nothing was changed in the radio from the last time I used it and it worked fine. Suggestions?

Re: [Elecraft] Calibration
Back in the day I kept a little note that told me how much to add for the preamp and my attenuator was calibrated in dB. It's nice to have the radio do the calculation for me. I especially like the P3 that reports the signal in dBm, not S units. Ron AC7AC -Original Message- Setting PRE or ATT causing the S-meter go up and down is how analog radios have worked forever. The S meter was reading the voltage off the AGC bus which usually controlled the gain of half a dozen tube stages. Some folks WANT their digital radio to behave like their previous analog radios and view every divergent behavior as something potentially wrong with their K3. They'll take the better performance, but they don't want to learn a new paradigm to use it. Hence a lot of dual personality items in the K3. But having the input absolute is indeed useful. In this mode PRE and ATT are just a range switch for RF gain. Like LOW, MED and HIGH... 73, Guy. __ 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

For Cebik the Ham radio work was obviously a hobby that he wanted to contribute to. For someone else, not a Ham, obviously it is not. Even so, it appears all of his original free articles are still available at no charge. It does require a simple log-in however, at www.cebik.com Ron AC7AC -Original Message- /soapbox on I think they are referring to the Antennex website http://www.antennex.com/Stones/st0906/antennex.html you know the one that took the free L.B.

[Elecraft] Audio Nulling in my K3 in Diversity Update = Solved
Hi Guy et All, Sure enough this only happens using an external speaker, the headphones work fine. Sorry for not seeing this earlier. I do have SPKRS set to 1. So it appears that when using diversity one must use Stereo speaker output and or Headphones. Mystery solved, Thanks for the quick answers 73 Dave Anderson, K4SV Tryon, NC 828 777-5088 www.K4SV.com - Original Message From: Guy Olinger K2AV olin...@bellsouth.net To: Dave Anderson, K4SV davek...@yahoo.com Sent: Wed, December 15, 2010 9:08:41 PM Subject: Re: [Elecraft] Audio Nulling in my K3 in Diversity The main ways of getting audio nulling on diversity are setting CONFIG:SPKRS to 1, or having the left and right speakers actually shorted out somehow, or getting one speaker cable to one speaker flipped, and the other not. Any of those? 73, Guy On Wed, Dec 15, 2010 at 8:55 PM, Dave Anderson, K4SV davek...@yahoo.com wrote: Hi All, For the last few weeks I have used the Diversity on the low bands with good success.
