Decoder bands for Yaesu/elecraft/Ten-Tec PCB
Band decoder converts BCD code from transceiver’s BAND DATA outputs to 6 open-collector
terminals assigned to 10m, 15m, 20m, 40m, 80m, 160m.
WARC bands are combined as follows: 30/20, 17/15, 12/10 meters. 30 meters could be combined
with 40m band by diode jumper if required.
The output ports DC voltage to control is up to 50 V with max current 0.5 A . PTT, ALC, +13.8 V
and GND lines are coming through decoder to control the amplifier.
