Sometimes we type the wrong key; Andy busted my call (W6FB), but I know he meant to type the right number.
As for the SteppIr discussion, I am curious. For those who control a SteppIR from a K3 or K4, how well does it work in split mode? The best test would be for a SteppIR that does 40 meters where split mode operation is common. Since the K3 only sends the Rx frequency in the IF command, you should see “High SWR” on transmit of the Tx frequency is far away. The test would be rx on something like 7120, Tx on 7290. You could try the same test on 10 meters where you could get farther apart frequency-wise, but split mode is seldom used on 10, except for repeater operations. One other observation - this issue would not happen with a K2, which sends the VFO B frequency in the IF command while transmitting in split mode. In split mode, the K2 receives on VFOA and transmits on VFOB. Life used to be so much simpler... 73, Jack, W6FB > On Mar 16, 2025, at 1:18 PM, Andy Durbin <a.dur...@msn.com> wrote: > > I had an interesting off-list email exchange with Jack, W7FB.
