This only happens on sn 2745   
SN 658 worked flawlessly

Yes, I first noticed it after the firmware started using the front panel
flash memory, though that may be a coincidence. I think the response time
depends on how busy the processor is, in other words, what it is doing at
the time. Some computer logging programs poll the radio excessively (in my
opinion, for example ten times a second) to get the current frequency, mode,
etc. If you are running such software at the same time as you are twiddling
the knobs, that could account for what you are seeing.
