I have an Ameritron al-811 amplifier that I'd like to hook up to my 6300. If I use a rig buffer like an ARB-704, do I need a special plug and play cable? Do I need a rig buffer? Etc. Thanks.
If you like the Rube Goldberg (if you remember that, I know how old you are) approach, I used a Radio Shack 5vdc relay and borrowed 5vdc from the accessory connector on the back of the Flex. I keyed the relay with the TX1 contacts and key my amplifier with the SPST contacts of the relay.
