[Elecraft] K3 Aux power relay source

[Don Wilhelm]

I don't understand what all the fuss about specific relays is all about.
Any relay that can handle the current desired and has a 12 volt coil 
will do the job.
Relay speed is not a consideration, it will pull in when the K3 is 
turned on, and will stay in that state until the K3 is turned off, so 
operating time is not a factor, only the contact current rating (must be 
sufficient for whatever accessories you wish to power), and the relay 
coil must respond to 12 volts and draw less than 500 ma.
