Preparations for Tuning the Transceiver
Before attempting to tune the transceiver, connect the unit to a
suitable power supply.
Whenever the transmitter is tuned, the unit must be connected to
a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a 8
Ω
dummy load and connected to an AC voltmeter and an audio dis-
tortion meter or a SINAD measurement meter at all times during
tuning.
