[hpsdr] Help with Mic input on Penny

[Richard Ames]

Dan -

Thanks for the suggestions....  

I am using pin 1 on the DB25 to assert PTT and that is working OK... so
no jumper on JP4.

I have tried two microphones - both work with the PC:

The electret I wired has bias and mic in on the ring so the two jumpers
are in the upper position.

The headset has the wiring sealed in --- I have tried both jumper
positions.

So far no joy....

Regards, Richard
