Ohm; maximum admissible input voltage from the transceiver (across an open KEY-OUT output):
+50V; maximum admissible current through a closed KEY-OUT output: 20mA;
- minimum dead time, necessary for safe amplifier switching from receive to transmit: 10ms between
transmit request at the KEY-IN input jack and the RF drive appearance at the RF INPUT connector.
b) Frequency control directly from CAT interface of the transceiver – connector CAT/AUX (connector type
c) Remote control through RS232 interface (connector type DB-9).
