[Elecraft] K3 - keying an amp

[Stewart Rolfe]

Hi All,

Just acquired my very first amp (Acom 1K) and intend hanging it off the 
back of my K3 in due course. According to my reading of the manual there 
is just a Key-Out line for switching an amp but no input back from the 
amp to inhibit the K3 tx until the amp is ready ('ground when ready', TX 
Inhibit etc...)

So was wondering if I'd missed something here and also was wondering if 
there is a variable delay function to adjust the timing between Key Out 
switching the amp and the K3 squirting out RF? Using a FT990 at the 
moment which has a TXInhibit function though apparently the timing even 
then is a bit tight for some amps' relays. As I said, it's my first amp 
so virtually no experience at interfacing these things and don't want 
fireworks, bonfires or welded relays with a new amp *and* new K3...!
