Using HRD sound card into rear panel auxiliary input.  With speech proc off I get only about 50 watts out with max audio drive measured on rf wattmeter.  The O2 meter shows 100 watts, not 50.  If I turn SP on, I can get closer to 100 watts out.  The O2 power meter appears to be reading 2x what is actually being transmitted?  And or the drive level without the SP is cut 50 percent?  What's going on in the DSP?  Any suggestions on how to get an honest 100 watts on Psk? Jim N4BE
