GA Win -

1. Loading on the WARC Bands must be done in the
CW/Tune Position.

2. Do not operate the amplifier in the SSB position on
the WARC Bands.

3. 17m
Band Switch - 15m
Tune - Top of the 40m markings
Load - 4.0

4. 12m
Band Switch - 10m
Tune - 20m (just left or CCW)
Load - 4.0

The are a number of variation on which Band Switch
Position to use and relative Tune and Load settings.

In either case DO NOT use the SSB postion (HV).

Good Luck es 73,

Jay/AF2C
