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 con-
nected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with
a 8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
