[1000mp] Receive/transmit antenna setup on Mark V

Tue, 29 Jan 2002 16:20:07 -0500

Top Ten devices has band decoders and antenna relays that you can key on
xmit using the linear amp jack on the back of the rig.  This jack sinks to
ground on xmit.  Any antenna relay will work with this jack.  It can be
isolated using a simple transitor & resistor circuit like the one used for
keying the rig with a computer.
