[Johnson] Invader 2000

[David C. Hallam]

Since the Invader 2000 has 2 antenna coax jacks, one for low power and 
one for high power, I am trying to devise a switching arrangement that 
will change the antenna coax from one to the other without my intervention.

What I have come up with is;

Use my B&W TR switch and a DowKey 110V antenna relay.  The antenna and 
receiver are connected to the TR switch.  The transmitter input of the 
TR switch is connected to the antenna connection of the DowKey relay. 
The NC connection of the DowKey, normally the receiver jack, is 
connected to the low power output, and the NO connection, normally the 
transmitter jack, is connected to the high power output.  Relay power is 
supplied from the fan circuit of the amp when the amp section is turned. 
  This switches the antenna connection of the DowKey and all I have to 
do is to turn the loading control to the amp position.

Are there any problems with this or has someone come up with a better 
solution?
