[Johnson] Invader 2000

[David C. Hallam]

Rodger,

I guess I didn't phrase my question in a clear enough manner.  I would 
like to be able to work 200W or 2000W at the flip of a single switch.  
Since the Invader 2000 has separate coax outputs for high and low, I can 
seem to come up with a reasonable scheme to make the change.  I would 
like to be able to change between the two by simply changing the setting 
on the low power loading between AMP and the loading setting for the 
antenna.  As it is now, I have to move the Dow Key relay from the one 
coax jack  to the other.

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.
