My HIFER beacon USC was received in VK land last week and positively IDed. It was running 4 mW to a 20 meter dipole 18 feet high.
Normally it transmits with a 1/4 wave ground plane vertical up about 30 feet but I changed the keying style to FSK and also moved the frequency and built another board. I shut down the normal beacon and hooked the test board for the new one to the low 20 meter dipole and left town. While I was out of town, I checked the reports from Australia and saw that the new beacon had been received and positively ID. It uses FSK QRSS 3 but still that is a long haul for 4 MW through 40 feet of RG 58 to a low dipole.
Below is a photo of the beacon as it is operating temporarily on the bench. I plane to put it in an oven for stability and roof mount it to the ground plane next week for a permanent installation. The beacon uses a PIC 509 8 pin processor and an Epson programmable oscillator.
