N1MM+ Running SO2V Mutes VFO A

  • Updated 4 years ago
During CQ WPX CW 2015 when running SO2V on my Flex-6300, with latest SSDR, when the TX focus is changed to VFO B, VFO A mutes the audio output. This prevented  hearing stations responding to my CQ. 

Reproduction steps:
1. Open two slice receivers on SSDR
2. Set N1MM+ to SO2V mode
3. Start calling CQ on VFO A (slice A)
4. Change N1MM+ screen focus to VFO B
5. Note that VFO A (slice A) continues to call CQ, but slice A is now muted. Issue happens every time focus is changed from VFO A to VFO B.

Do you use SDR Bridge? If so, check that the "Mute all but active slice" checkbox in the Radio-Tab is unchecked.

This is, how I configured it: HOW-TO: Setup FLEX-6X00 with N1MM / CW Skimmer for multiple slice contest operating

Thank you for the reply. I think that was my problem, since I was using SDR-Bridge. I will confirm this later.

I was running my 6300 with N1MM Logger+ in SO2V during the contest.  I do not run a Skimmer or SDR Bridge.  I did not have the audio muting program that Eduardo wrote about.  I do encounter a different problem.

I do use Flex Control.  When I open the second slice's  panadapter I can switch between panadapter A and B fron N1MMLogger+.  I can transmit on the correct slice and hear both slices.  

But, I can not change the frequency of the second slice.  To do that, I have to click on the second slice.  Then the Flex Control allows me to tune that second slice.

When I move back to slice A from the logger I see the same issue.  Turning the Flex Control knob continues to change Slice B until I mouse over to slice A and click there.  

Anyone else have this problem?
