I said I would dig out my 'special stash' of 7 segment displays for you
It would be one hell of a NAV radio with these boys in.
There's an ancient mega there to compare the size to. The image is the full size lid of my laptop. There is also a 0.3" 5 digit to compare

Hi Keith,
Just check the values of R1 and R2 (iSet) for the 7219s on the schematic.
you have 40K ohms.
I would suggest around 12K or your displays will be far too dim to operate properly.
