[Elecraft] K3 Remote question

[Tom Georgens]

Hello

 

I am contemplating building some remote capability for my station.  I am
early in the process and want to do some basic testing.  Can I just connect
two K3 radios with a Null Modem serial cable or do I actually need the
RemoteRig hardware to make the remote functionality work?  It looks like my
setup is the opposite of the design intent of the RemoteRig and I am
interested in seeing how  the radios behave before I move to the design
phase

 

Thanks and 73
