(11-3-08) I just received 25 prototype boards. Paypal buttons are on the "Under Development" Page. An 80M filter has been assembled.

Each of these 8.1 by 2 inch boards contains a single band diplexer and 3 relays. The boards are on .126" FR4 and use 2 oz(normal is 1 oz) copper for added current handling capability. Designs for the other 5 filters to cover the 1.5 to 30 MHz spectrum have been completed using RFSim99.
