Assembled and tested 500 MHz frequency counter with CW readout. Based on
the Mcount kits by Jackson Harbor. Good accuracy through 70 cm.
Especially useful for the visually impaired and others who would rather not
tackle SMT assembly.

Mike's comments:
Physically, it's about the size of a new bar of soap.
You need a few feet of wire for the antenna unless you have a bunch of rf in
the shack.
