CM Coupler Balance Adjustment
1. Terminate the antenna jack with a 50 Ohm dummy load.
Set the mode to CW, and connect the DC voltmeter to
J3004
(pin 7).
2. Tune the transceiver to 28.000 MHz, and key the trans-
ceiver.
3. Adjust
TC3003
for minimum indication on the DC volt-
meter.
4. Tune the transceiver to 145.995 MHz (CW), and key
the transceiver.
5. Adjust
TC3001
for minimum indication on the DC volt-
meter.
6. Tune the transceiver to 439.995 MHz (CW), and key
the transceiver.
