[Elecraft] Remoting K3 and Expert 1.3 using RemoteRig RC1258

[Roger Dixon]

Hi All,
I'd be interested to hear from anyone who has successfully remoted a
K3/Expert 1.3 combination using a RemoteRig RC1258.
We have successfully established a link to the remote K3 using a K3/0-mini
and have full functionality on CW and SSB.  We have also managed to
integrate DXlog at the control station.  Good news so far!!  However,
attempts to control the Expert 1.3 over the RC1258 COM1 channel have failed.
Has anyone else successfully achieved this?
TIA and 73
