I have put together some kits that can be used to build a rather
interesting HF radio.
dds board: 1MHz-140MHz, with microcontroller CAN and RS-232 interfaces.
RX: board VLF-VHF (50KHz-52MHz), single conversion, 70 MHz IF, double
sideband product detector, works with above DDS boards. These boards
have all wideband technology, up to 14MHz bandwidth from the IF. InGaP
frontend and IF amps, diode ring mixers, separate IF out and detector
AF/Actiive filter board: An AF preamplifier with active audio filter
for SSB/CW. For use with above RX board.
All feature surface mount technology in a small form factor (approx:
2.5" X 3.5")
These kits are very much limited production at this time.
