[Elecraft] AUTOINF Auto 1 Anomaly

[Mike K2MK]

Hi Rick,

I would like to comment on the mystery cycling between 14000 and 14050. I
have experienced this behavior. Do you have more than one SteppIR
controller? Are they slaved together and is the master controller the older
style and the slave controller(s) the SDA100 style?

If yes, then the problem may be caused by the fact that the old controller
resolves frequency to 10Hz and the SDA100 resolves to 1Hz. Logging programs
tend to request frequency information every second or so. The SDA100 display
will immediately display the exact frequency. But a second later it will
correct itself to the 10Hz resolution of the master controller.

73,
Mike K2MK
