On the OpenHPSDR/PowerSDR main window, use the "TX meter" [Upper right corner] dropdown box to
select "Mic".
Press your Mic PTT button, keyboard space bar, or click the "MOX" button on the main form to key the
radio. With the radio keyed and while speaking into the mic in a normal voice adjust mic gain for peaks
0db.
If 0 db voice peaks cannot be achieved with the slider at the extreme right, go to the Setup, transmit
tab [lower left], check "20db mic boost" and try again to adjust the "MIC" gain control on the main
OpenHPSDR/PowerSDR window for 0 db on voice peaks.
If you are still unable to achieve 0 db on voice peaks:
[a] Check your JP4, JP5 and JP6 jumper settings on the Hermes board.
[b] Try a different mic.
To enable or disable COMPRESSION you click on the COMP button. We recommend that you set
COMPRESSION to no more than 6dB.
