Need to hook HW-22A to SB200 Amp- Relay???

[Larry Gauthier]

Richard,

The HW-x2 series used a pair of dry relay contact that are closed (shorted)
to ground when the rig goes to transmit mode. _IF_ your newly acquired 572B
amp simply needs to have the transmit connector shorted to ground (which is
very likely - that's how most of them work), then you can connect your amp
relay connection directly to the HW 22.
