[Elecraft] [K3] K3/0 Remote Rig QRQ / QSK performance

[Mitch Wolfson DJØQN]

Chuck,

You must set the rig's sidetone to zero to keep from driving yourself 
crazy. This is possible with virtually any rig (at least any modern rig 
I have used), not only the K3. You will have sidetone generated locally.

For attaching an external keyer, refer to appendix B on page 228 of the 
RemoteRig manual on how to interface an external keyer directly to the 
RRC's I/O jack:
