[Johnson] Invader 2000

[WQ9E at btsnetworks.net]

David,

It is mostly covered on page 6 of your manual (at least the January 1961 edition).  I use a coax switch to connect either the exciter or high power output of the 2000 to the input of an antenna relay.  The relay is powered by J5 (provides 110 VAC on transmit) and has an auxiliary set of contacts that I use for receiver muting.  You could also use the relay built into the 2000 for receiver control but I am used to using relays with the extra contacts and I don't operate the 2000 on VOX so I don't need the additional speaker muting provided by the relay connections at J2.
