Doug, N3ZI, was one of the intrepid participants in the ARRL Homebrew Challenge competition. FB! He is now making available some very inexpensive digital frequency readout kits. Jerry, NR5A, sent me one. (Thanks Jerry!) Obviously this is a kit useful to Knack victims.
Here is the web site for the kits: http://www.pongrance.com/
Good enough for your QRSS needs Bill?
