[hpsdr] PS input signal

[Bill Diaz]

Glen,
    The receiver ADC clips at -17dbm or so.  A -10dbm sample from your 
external directional coupler should be automatically be attenuated to 
the proper level for PS operation if you are using PowerSDR/Thetis and 
have "ATT on TX" checked on the Ant/Filters Antenna checked.  The 
receivers 31db step attenuator is used to attain the proper level, 
provided the input sample level is not more than about +14dbm.  
Therefore, a sample level between -10 and + 10 should work, provided 
your external directional coupler has relatively linear output from 
160-6m.  YMMV.
