You're welcome George. I use an Audio-Technica AT-3035 condenser mic. into a W2IHY 8 Band EQ directly into the Delta 44 input #3. I mute input #4 and uncheck "stereo link" in the Monitor Mixer portion of the M Audio Delta Control Panel. I use a footswitch into the back of the SDR to key the radio. I do not use the EQ portion of the W2IHY box. I only use the mic. preamp section. Any low noise mic. preamp providing the proper phantom voltage for a condenser mic. will work. I do use the EQ software in PowerSDR. My PowerSDR EQ settings for "conventional" audio are 0, 0, +3, -6, -3, +3, +12, +10, 0, 0. My "conventional" transmit settings allow for 130 Hz-3,000 Hz transmissions. I always receive "outstanding" audio reports. In a quiet room, my background noise measures -15 dBm. I modulate the radio to about 0 dBm (never over) by watching the TX Meter selected for "mic." My mic. gain is set at 25. With my microphone disconnected, the "noise" measures -26 dB. That's lower than my background noise by at least 10 dB. I "could" turn up the mic gain beyond normal operational levels, but, there's no practical reason to do so under normal operating conditions. For DX, AM, and ESSB operation, I change the PowerSDR EQ and transmit width settings. I set all of my PA settings so that a 'front panel' drive setting of 50 is equivalent to about 35 watts, which is enough to drive my Alpha 99 amplifier to 1,500 watts. This scheme works very well to drive my amp to full output and I always get excellent or better audio reports. The microphone you use and your voice characteristics will cause deviations from this model, but this is the model that works very well with the equipment I use. Hope this helps.

Reading back through the archives it was suggested that putting the mouse arrow over the MOX button allowed the space bar to be used for PTT. That actually works pretty well. Though I've had the radio almost a year, I've been using it mainly for digital modes. The SSB bug just bit a couple of weeks ago and it became a mission to get the SDR-1000 on the air with good audio, which it didn't have before running just a standard microphone.
