VFO CTS changing

[ab2tc]

Hi,

I am on the latest firmware, 2.76. Recently I have played around more with AM listening on the SWL bands and generally found it enjoyable (audio clearly there from 100-4200Hz when set to do so!!). However there is definitely an anomaly with the VFO tuning rate (steps per revolution "VFO CTS"). For normal SSB ham band use I have this set at 400.  If I go to AM mode and press coarse to set the step to 1kHz, this gets changed to 100. This may be intentional; at this big tuning step, 100 steps per revolution is OK.  But if I go back to SSB and 10Hz tuning step, the "CTS" is still at 100. I believe this has been around for a while since I have many times inexplicably found my "CTS" being set to 100. I can't recall seeing that the "CTS" should be mode dependent in any way and I think it's best if left totally mode independent.

I this is really happening, Knut, I'll fix it in the next revision.
Thanks for letting me know.

I am not sure that VFO CTS is working properly in 2.78.  One complete
revolution of the VFO knob changes the frequency 2KHz in CW mode for
me.  This appears to be the VFO CTS value of 200.  However, I see no
difference if I have the value at 100, 200, or 400.  Am I missing
something here?

I have found that a change to VFO CTS does not take effect until power
is cycled - try that.

Hmm, okay, that works.  Seems like a bug to me then.   Thanks!
