All measurements were made with respect to ground with the power supply disconnected from the

and XMTR GAIN controls were fully clockwise. The VOX, ANTI VOX and SIDETONE controls
were fully clockwise and the ZERO control was set at the balance point. The accessory 34-PNB
jumper plug was in the noise blanker jack.
