Connection Diagram
High Speed Switching
Connect the RF output of your transceiver to the RF IN connector on the rear
of the HF-2500\HF-2500 MAGNUM with 50 ohm coax. Connect the existing station
antenna system to the RF OUT connector on the HF-2500\HF-2500 MAGNUM with
RG-8 type coax. Connect the RELAY phono jack on the rear
of the HF-2500\HF-2500 MAGNUM to the normally open terminal of the RELAY
jack on your transceiver. The RELAY jack on the HF-2500\HF-2500 MAGNUM has
positive 20 VDC open circuit and requires the sinking of 300 UA of current when
pulled to ground. Connect as short a ground lead as possible from a good earth
ground to the GROUND post on the HF-2500\HF-2500 MAGNUM. The 12 VDC
phono jack on the HF-2500\HF-2500 MAGNUM rear panel provides 12 VDC at 100
MA maximum to operate external accessories or dial lamps. Connect the ALC
phono jack to the ALC connection on your transceiver using a shielded type cable.
Consult your transceiver manual for proper ALC connection details.
