I have noticed what you describe below with all versions of firmware. I have verified that it occurs both on transmit and receive. At the most you could be 99Hz off of your displayed freq. If you were at say 14.200099 in the fine mode and then switched to coarse display of 142000 you would actually be transmitting and receiving on 14.200099. The 99Hz will always be there even if you move the VFO. I find this irritating but since I am aware of it I can work around it. I hope that it will merit a future update

Let's say I'm tuning in FINE mode (to the 1 Hz digit) and the VFO says 50.135.056. If I then go to COARSE (to the 100 Hz digit), tune to a VFO indication of, say, 50.145.0, I intuitively expect that the actual VFO frequency will be 50.145.000 -- but it continues to carry the FINE 10s and 1s digits as an offset, so the actual frequency is 50.145.056, which is revealed by tapping the FINE button. This was probably an intentional design choice based on how other rigs work -- but it's not the way it seems like it should be, to me. Intuitively, it seems like if it says 50.145.0, it should be 50.145.000. Am I completely wrong-headed here? Comments?
