[hpsdr] Penelope Modulation

[Gary Beech]

Hi All,

 

Thank you to all who responded to my previous post.

 

I now have made some progress with my Penelope board.

 

When running the two tone test from the built in test tab I get good output
from the TX.

 

If I apply a 1KHz signal from a signal generator to the Mic. my output is
about 20 dB down( just before saturation) on the built in 2 tone test.

 

When I connect a microphone to the same  Mic. input the same problem exists.

 

I have tried setting  the Mic. gain to maximum and the 20dB boost this has
not helped.

 

Thank you
