SB-200 Standby

[W6CUX]

Replace the SWR sensitivity pot with a like pot except with an ON/OFF 
switch. Route the keying line through this switch. Now, when you want to 
key the -200, just turn the SWR pot sensitivity "upscale".

The right size pot and switch are available in inch dimensions and 1970 
prices at:  http://radiodaze.com/

You should also install the Harbach SoftKey module**. That keying line 
is pretty rough on modern transceivers.

**Instead of screwing the module down, attach it with two layers of 3M 
Mounting Pads. It will stay there forever.
