[Elecraft] K3 Keying external Amps

[Lance Collister, W7GJ]

Hi Richard,

If both amplifiers use transistor switching, you may be able to simply connect the 
two in parallel and use the K3 to activate whatever amp is turned on.  I am sure 
there must be better ways to do it, but simple often has a lot going for it.    I 
have the key out of my K3 connected to a TE SYSTEMS 0552G amp for 6m and a Mierage 
B1016 amp for 2m.   No problems yet ....  GL and VY 73, Lance

Now that I've installed a K144XV board I want to key a 144Mhz block amp.  I wondered how my fellow hams are keying two seperate amps separately with one key line?  Thank you.
