[Elecraft] Fool proof kill switch = deadman timer?

[Fred Jensen]

I run Remote Rig with W7RN.  In terms of what I think you're looking 
for, it really doesn't provide anything. It's a control and audio 
interface between two rigs.  With K3's at each end, and an IP path to 
the remote RR box, turning on your control K3 puts it in TERM mode and 
turns the remote K3 on.  Your K3doesn't make any RF but it behaves 
exactly as if it was, your display is a carbon copy of what the remote 
K3 is doing.  RR will work with other radios, Ihave no experience with 
any of them.

Depending on what might be hanging the remote in TX, turning your 
control K3 off may or may not fix the problem.  As Rick, N6XI, says, 
"Remote Rig involves a *lot* of 'moving parts' and is non-trivial to set 
up."

"Carbon Copy:"  An ancient method of making one or more copies of a 
typewritten document while typing the original.
