Hi Folks Getting a few reports of slightly ragged SSB audio TX. check here definitely NQR ( not quite right ) Used another receiver to chase the signal path from the SSB board to the power stages. Distortion is in finals. They appear to be on the very edge of class B. Deceased resistor value R59 to increase bias current. My K2 meter may not be accurate; previous value TX showing 0.64A , moved to 0.78A. Received audio is now very clean. R59 value approx 1K. No apparent increase in temps with casual use. serial 6534 built several years ago.
