Re: [Elecraft] K3 - Can't hear 40m sigs in sub rx

[Nr4c]

Use BSET and check antenna selection on 40m. Bet it's on wrong antenna.

Ah, I understand. That puts a different slant on the subject.

Thank you!

John,

Normally the P3 does not show signals from the subRX.  The IF out is 
only from the main RX.
Unless you have added an IF buffer amplifier and IF output to your 
SubRX, you will not see signals from the subRX on your P3.

John,

The most common cause of that problem is the SubRX antenna selection - that is 
a per band setting.

Go to 40 meters and get into BSET - then tap the RX ANT button.

If that does not restore proper operation, contact Elecraft support.

I’ll check that, but it seems that if there was no antenna, there would be no 
signals in the sub rx on 40 meters, and I’m seeing the signals on the  P3, I 
just have no audio.

I did try that, and it made no difference, looked like everything was set OK.

I’ll contact Elecraft.

The problem is that I cannot hear any signals in the Sub RX on 40 meters. I’ve 
tried headphones, internal speaker, external speakers, all the same problem. If 
I turn up the Sub RX gain a LOT, I hear a little noise, but I think it’s just 
receiver noise. The problem is only on 40 meters, in all modes. All other bands 
are working just fine.

The signals are there, because I can see them in the display of the P3. In 
fact, I’ve been working around the problem in split DX pileups, determining 
where the callers are by watching the traces on the display and positioning the 
transmitter accordingly.
