[Kenwood] Relay rating in 450/690

[Joseph J. Duerbusch]

Alan, from what I know, the relay is rated to handle the Kenwood TL-922A 
   so it should work with any Amp.

But Rich Measure wrote an article about the TS-440S and the amp relay 
and said it was too small.  Read it for yourself at:
http://www.somis.org/440.html

Richard has a small transistor keying circuit in that article and 
mounted it inside the TS-440S.  I took the circuit and mounted in a box 
external and used the +12 volts on transmit to drive it.  This way, I 
did not have to use the relay (in my TS-850S, no noise) and it keyed 
very fast.  I am using it with a Drake L-7 Amp.

Please check out my webpage at:

for the information

I know you wanted the ratings, but that I don't have.

Hope this helps.
