BARRETT 900 SERIES TRANSCEIVERS
5.8.4.3 Power level adjustment
5.3.4.4 Programmable links
The high power adjust set pot, RV4 sets the power level at 100 W. In the case of the 940 only low power is
used and it is set between 10 W and 35 W. This should not be adjusted without access to a two-tone test
source and a peak reading watt meter. High intermodulation levels can occur if the potentiometers are
incorrectly set. Set frequency to 7MHz and SSB mode.
The only user selectable link on the PA PCB is normally left open. Where an auxiliary antenna socket is
fitted, the link can be inserted to obtain separate Tx/Rx sockets or separate socket routing depending upon
the channel programming.
