■ Modifying the Transceiver
• Horn alert

The signal from pin 4 of IC9 on the TX-RX unit turns Q5

and Q1 on and off and drives KAP-1 HA relay K2 to drive the
horn with a maximum of 2A.

The default output is HR1.  The relay open output can be

obtained between HR1 and HR2 by removing R1 in the KAP-
1.
