I was thinking, I love the V1 interface, except for one thing... the band identification. It's impossible to see at night, and you have to look too hard any other time. How about this...
Ya know the bogey counter? Well, it's one of the standard 7 segment displays that when all lit up makes an 8.
Well, what if, for band identification, another one of these was placed on the V1 that would say X, K, Ka, or L. You would have to add some segments, and make it wider, but it would work great, blend in with the rest of the V1's display and probably cost less than an LED matrix.
or ka could be something more like this:
Note: I'm sure some of this isn't going to cooperate as the text gets changed a little when you submit a post. If the top of the 8 and a are off it's because of how the board accepts text.
