‚ P ‚ Q RX AMP OFF/-20dB/+6dB/+15dB (SELECTION SWITCH):
Selects the gain of the RX pre-amp. Select the proper gain so that the signal can
be copied most clearly.
‚ P ‚ R POWER LEVEL HI/LO (SELECTION SWITCH):
At 10W and 25W inputs, the power level can be switched to either HI or LO. At
the LO mode, the output power becomes approx. half the HI power. (At 50W
input, the power level cannot be switched to LO.)

Selects the changeover delay time for TX/RX transition when the operation is
made with the RF key. It takes about 1 second for TX to change to RX state.
When the switch is pressed for FM operation, TX state will instantly change to
RX. For CW, keep this switch pressed ON (SSB position) and for the packet,
keep it pressed OFF (FM position.)
