[hpsdr] Hermes/Angelia Microphone Recommendation

[John Marvin]

A pure  dynamic microphone requires the type of boost described (20-25 
db beyond the 20db mic boost setting). An electret condenser microphone 
that uses the power that Hermes can provide on the mic jack will not 
need as much boost.  Looking at the Heil website it's not clear what 
type of microphones they use on their headset/boom mikes. It looks like 
they may provide both types, with most of them being dynamic but some of 
them being electret condenser.
