Hi Mike,
How about a counter for about $10 delivered? Take a look at eBay item # 121239170838 . Quite a few people have had success with these cheap counters. Red, Blue and Green versions available.
Look at the eBay opportunist that is putting these displays in a case and selling them for $150! See item # 353595762412. He actually started off at $250!
Display Dimensions: Length — width — height : 91 mm — 28 mm — 20 mm. You may want to put black tape over the digits you don't want to see so the 91 mm would be reduced for the FRG-7 window.
The FRG-7 VFO works backwards. The low end of a band is 3.455 MHz and the high end is 2.455 MHz. The display allows count direction and offsets to be programmed in. 3.455 MHz in would read 00.000.0, 2.555 MHz would read 00.900.0 and 2.455 MHz would be back at 00.000.0.
There is a lot of info on the net about programming. Even some uTube videos.
