Problem with mic input
« on: 2020-10-23, 19:23:57 »
I assume the RRC wants to see a dynamic mic. My Heil HM10 keys my control FT5000 directly. The Heil push button mic keys the remote radio through the RRC, but that mic is not useful for phone contesting via VOX. However the same HM10 will not key the remote radio via VOX. What could be my configuration problem?

George,

No problem to turn bias on in the RRC, just look at the jumper settings in the manual.

To make VOX work, the RRC's must have RTP set to continuous.

Mitch, the RTP change worked, but I didn't put the JMP1 jumper back in until today.  It still did not allow the Yamaha mic to key the radio without the bias module, or even with the bias module.  I thought I had ironed out most of the issues with this setup by last week when I was able to make over 600 QSO's in 76 DXCC entities in the CQWW SSB cotest.  However, today I still have a number of other issues with the remote connection to the FT-5000 in Quebec:
--the Remote radio does not reliably switch mode from CW to SSB with the Control radio front panel buttons.  Often does not switch from USB to LSB, or from USB CW to LSB CW;
--the Remote radio does not respond to the Control radio DSP filter IF shift;
--the Remote radio does not respond to the Control radio DSP filter Width;
--I have a recording of my signal on SSB showing the first few msecs of my transmission are cut off, not fixed with VOX delay.  The same anomaly was reported during a CW QSO.

There are probably some esoteric settings in the RRC that can resolve these.  Your advice is welcome as always.

Hi George,

I just saw your posting today, sorry.

The issues you describe are bugs in the implementation of the Yaesu Twin mode for that rig that
we discussed a couple of months ago. There is nothing in the RRC settings that will solve them.

The only solution is for Microbit to fix them with a new firmware version. Since we have been waiting
several years for this to be fixed, I wouldn't hold your breath waiting, sorry.
