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 distortion meter or a SINAD measurement meter at all
times during tuning.
