10.0 TRANSMIT QUALITY TEST
This will test for good quality of voice transmitted into a dummy load,
and received in a close-by radio set on the same frequency and mode.
10.1 Use a known good microphone and transmit a few phrases of test signal
to a near-by radio set on the same frequency.
10.2 Listen to the quality of the voice in the other radio while monitoring
modulation on the scope attached at the output of your radio's dummy
load.
11.0 RECEIVER CURRENT TEST
11.1 Connect RF Generator at the antenna connector, and an ammeter in series
with the radio.
11.2 Radio settings - 14150.0 KHz USB, AF max., RF max., BW 2.7 KHz.
