[Elecraft] Band Data output?
Elecrafters, i control a 6*2 switch via a remoteqth.com Band Decoder II using RS-232 sniffing mode. Not happy with that. I like to switch to Band Data output from the 15-pin sub-D ACC connector, but am a bit confused. The band decoder manual shows connections labeled BCD-1 through BCD-4. The K3 manual labels it's outputs Band0 OUT through BAND3 OUT. What goes where? Thanks.

[Elecraft] Diversity RX with K3 + Sub RX
Elecrafters, i recently bought a used K3 with Sub RX and KAT3A internal ATU. I've enjoyed Diversity via SUB RX on my older K3, but never had the bells and whistles of the ATU. So with -say- a vertical Antenna attached to Ant1 and a Dipole to Ant2, i can receive Diversity (if distance between them is sufficient) . Can i assign TX to Ant2 and still receive Diversity? Is there a macro for that? 73, Martin __ 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 Message delivered to arch...@mail-archive.com

[Elecraft] K3 and CW-Skimmer
Elecrafters, i know this is not the right place - and off topic- , but i hope for a quick solution to the problem without the need to subscribe to yet another forum. Problem: I set up CW-Skimmer / LPPan / K3 . When i click on a signal i see on the waterfall, the K3 jumps to that frequency. In some cases i then hear and see the signal exactly where i expected it, in other cases the signal shows up in a different place on the waterfall. I tried to compensate for that offset per the manual , but i just don't understand the mechanism behind it. The manual says 24000 ( might be 2400 as well - i don't have cw-skimmer on _this_ pc ) is a good starting point, but that seems to be _far_ off.

Re: [Elecraft] DC-supply for a preamp?
Hello all, thank you for all the info about losses in a coax cable, but the original question was if this is a good or a bad idea. Lots of qsb, so it disappeared in the noise. :-) I've been thinking about it myself, my conclusion is: no good idea. Even if the K3 passes the supply voltage to it's antenna jack, bad things can happen if you forget to switch the supply off, when you change antennas, switch to your dummyload, you name it.

[Elecraft] K3: Power not restored when swapping A/B and back
Elecrafters, I intend to hook up an external XVTR, so i tried this: I set one VFO to a 2m-frequency and PWR to the Milliwatt-range, set the other VFO to a shortwave band and PWR to - say - 100 Watts, then swap A/B to make the shortwave band VFO B and 2m VFO A. When swapping the shortwave band back to A, the high PWR is not restored. Holding XMIT outputs the preset PWR, 10 Watts in my case. To restore PWR i need to crank up the PWR-knob from Milliwatts to high PWR or use PFx. FW 3.76 KXV3A No Tuner Other observation: When i switch on TEXT DECODE in CW, the AGC acts slower.

[Elecraft] Kenwood HS-5
The Kenwood HS-5 headphones are designed for radio communications and sound very good with the K3. They are mono but it is easy to convert them to stereo. The cord has 3 wires: ground, left speaker, right speaker. Left and right speakers are wired together in the mono plug AND in the earpiece where the cord goes in. Open the earpiece: Use a tool that won't leave scratches on the earpiece. Pry off the perforated metal cover being careful not to damage it. Pry off the plastic cover, it is held in place by 2 clamps. You will feel where they are. Use gentle force. Cut the red wires off the speaker, solder them together then insulate them. Leave the white and black wires in place. I would not solder the red wire off, it is too big a danger to unsolder the very very thin wire going from the PCB to the innards of the speaker. Re-assemble. Replace the Mono-plug with a stereo plug. Solder the black wire to the ground ring. Red wire to tip and white wire to the middle ring, or vice versa, depending on which side you like to have the right channel AND on which side you like to have the cord. You'll be rewarded with plenty of audio and good sound.

Re: [Elecraft] Filters for K3
Elecrafters, thanks for all the input. I had many replies, personal mail or via the reflector. To sum it up: Matched filters are important for diversity. 8 votes for the 1.8khz, 4 for the 2.1 ssb filter for contesting. Some use the 1.8khz ssb filter for cw, with the dsp set to narrower bandwith. I think i will order one of those, it makes sense to use it for cw-operation on a quiet band and in ssb contests when things get rough. The 200hz and 250hz cw filters got an equal number of votes, you left me alone on this ;-) The expense on 2 matched 5 pole or 2 8-pole filters is about the same, so the criteria here is performance.

[Elecraft] K3 strange rx noise
Elecrafters, i had a strange noise on 80m ssb last night and the night before. When tuning up the band, the noise set in at exactly 3.686.000 like someone had flipped a switch. It went away at -say- 3.692.xxx, i can't remember exactly. When tuning in the opposite direction, it set in 1 or 2 khz below the frequency where it stopped when tuning upwards, and went away when tuning below 3.686.000, again like with the flip of a switch. I could repeat that several times. It sounded like a totally overloaded frontend. Like the bandfilter was bypassed. Like the whole 80m-band was received in that small portion of the band. I heard cw, ssb, harsh noise, all over this small frequency range, even on a single frequency, no matter where i tuned. It imediatelly went away when i switched ON the sub-rx, and IT STAYED AWAY when i switched the sub-rx OFF again. All back to normal, with some stations ragchewing in that portion of the band. This is the best i can describe it with my limited knowledge of the english language. I could not get the K3 to do it again. It seems like the K3 was stuck in a weird condition. Firmware is latest, but it also happened with the earlier firmware.

Re: [Elecraft] K3 SWR Accuracy - reprise
I don't have the KAT3, i use an external homemade tuner and a cheap swr-meter between it and the K3. Don't know how accurate the swr-meter is, but i notice that the K3 shows 1.1:1 while the external meter still reads worse. Fiddling with the controls of the tuner settles the needle on the external meter, while the readout on the K3's display stays unchanged. I posted this to the list some weeks ago, but nobody noticed. -- 73, DM4iM __ 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] K3 SWR Accuracy - reprise
I was using 4 Watts, the external bridge is a taiwan-made AV-20, I forgot the brand name. There is a sticker, it says accuracy 10%. Today I tested again using 10 Watts, the K3's and the external meters readout match a lot closer. With 10 W i can bring the K3s readout to 1.0:1 , with 4 W it was never better than 1.1:1. At 100 Watts , both meters agree in the range from 1.0:1 up to about 3:1. That is good enough for me. I don't care much about a perfect swr, but the components in the tuner *do* care when the K3 drives the Alpha. It should not be too bad then. :-) Martin -- Wayne Burdick schrieb: What power level were you using? And what type of external bridge? The K3's SWR bridge has two sensitivity ranges. If you have power set to 12 W or lower, the higher-sensitivity range is used. If you have power set above 12 W, the lower-sensitivity range is used. This is necessary to prevent heating of the transformers in the bridge. SWR accuracy will be best when you're in the upper part of each range. So, for example, it'll be more accurate at 12 W than 1 W, and more accurate at 100 W than at 13 W. But accuracy should still be reasonable even in the lower end of the range. Your external bridge may have better sensitivity at the particular power range you were using. 73, Wayne N6KR -- 73, DM4iM __ 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] [K3] New K3 feature -- need testers: Main/Sub Audio, Mixing Control (MIX menu entry)
Elecrafters, I subscribed as a tester for the Macro Switch Customization, only to find , after recovering from the CQ-WW, that other testers were very busy creating and testing macros. Even the Manual has been updated already. Wow! So the macros i created are already there , slightly different, but there's no need to invent the wheel again.

[Elecraft] KDVR issue?
Elecrafters, can anyone double this: If you Replay a message, say M1, tapping the button *twice*, these things happen, depending on how long you waited for the second tap: Tap twice fast (1/2 second pause): Message stops, then plays again. Tap twice with long pause: Messages fully plays, but RX-Audio won't come on for about 1/2 second after message has finished. Let the message play nearly to its end, then tap: RX-Audio won't come on for even longer (felt like this).

Re: [Elecraft] [K3] Feature request
The Smiths wrote: Actually Martin, I do use the RIT with the Split mode. Here's why: Some times when you're listening to the DX station, and other start transmitting on top of him, it's nice to RIT away from his beat Freq. up or down a little so that you can move the shift knob over +/- and get rid of those other people. Or just improve the ability to hear a weak signal once you've used the auto spot feature. Although you're idea isn't all that bad, assuming it's off.. Ok, so what about this: A single-tap clears RIT if RIT is ON, does nothing if RIT is OFF; double-tapping clears RIT (if ON) *and* sets the RX-Vfo back to the configured offset. From: hamra...@vr-web.de To: elecraft@mailman.qth.net Date: Mon, 19 Oct 2009 23:11:41 +0200 Subject: [Elecraft] Feature request What do you elecrafters think about this: 1. When you are running SPLIT ( assuming RIT XIT are OFF), tapping CLR puts the RX-VFO to the same frequency as the TX-VFO (TX). No one would run SPLIT and use RIT and/or XIT simultaneously, would you? 2. Or, even better: When you are running SPLIT, tapping CLR puts your RX-VFO a (config)-selectable number of +- khz (starting with 0 khz = no SPLIT) offset to your TX-VFO. This ensures that DXPeditioners or Contesters easily can return to their announced qsx-freq. Sorry for the bandwidth if there is already a method to accomplish this in a similar way. I must have missed it then.

[Elecraft] SWR-Meter acurracy?
Elecrafters, please comment on this. Is there a way to calibrate the SWR-Meter? I have a K3 w/o internal Tuner. With a Dummy connected, the SWR readout never is better than 1.1 : 1. Not that this makes any difference but i have seen a readout of 1.0 : 1 on a second K3, also w/o internal tuner. With an external SWR meter connected, while matching my dipole with my homemade tuner, the K3 shows 1.1:1 long before the needle on the external swr-meter settles. In other words, the internal Meter shows good swr, the external meter shows that it is possible to set it even a little better. I ask for your input on this because i run a tube amp and Tuner. The lowest swr possible helps the tuner amp to stay cool -and the owner. The external Meter is hooked between the K3 and the amp.

The pins of the sub-out and the sub-in board are correctly mated with their sockets. The Aux-DSP ist seated correctly etc etc.. In short, to me everything looks fine. I carefully read the manual in order not to make any mistakes with the antenna-connections and/or the selections of the antenna inputs. The sub-rx *will not work*. I have : Noise , but no band noise. Faint signals, but this might be a leakage from the main-rx. A 2.8khz 400hz filter in position FL 2 3 , so even if i counted the positions backwards , one of them should work. So, what can i do?
