[Elecraft] K3 & amp

[r miles]

Only familiar with Heathkit amps. Driven an SB200 & SB220 with various solid state 
radios. Ic 730,TS 430,Ft757,IC746. I used an Ampkeyer between the radios& the Heath amps. 
There are various interfaces. Some radios it's over kill but some need it. 
It also a safety too. The Heath turns on 120v to key the relay. Lots of new 
radios use a reed relay or electronic switching. 120v WAY too much for them. $30 
is not a big expense compared to fixing a radio or amp. Elecraft says I can key 
my Ameritron 811h but I use the Ampkeyer interface anyway.  Can't be too 
careful. I saved my Kopeks for a while to get my beautiful K3.I don't want to have to run the back up radio. My opinion is 'better safe than sorry'
