Subject: [Speleonics] "DQ" Radiolocation PC Boards Again Available

When a friend needed 2 boards for my venerable "Double-Quadrature" 3496
Hz radiolocation receiver and beacon, I had 10 made. There are 8 sets
available for sale at cost, $26.00 US per set, including US postage.
Each board includes the main detector board, "RF" amp, and a beacon. See for details.
