Digital modes are a lot of fun, and CS-series or KN-Q7A plus Sandwich digital VFO works great so far with the specially made firmware by JH3BTK.
Larry's modification to add a OLED display seems to be quite promising. My personal preference is the same as yours - the smaller one - so you don't have to move the IF GAIN potentiometer.
