6m & 10m SSB/CW Transceiver for the ARRL ‘Homebrew’ Challenge III
This is my entry into the ARRL ‘Hombrew’ Challenge II, which is a contest to develop the best 10m & 6m SSB/CW transceiver.
My objective was to make the highest performing radio using some new technologies for the amateur radio ‘Homebrew’ community.
New technologies include: op-amps for pre-driver and first IF amplifier, Si570 VFO, NXP LDMOS BLF645 for the PA, and a robust audio derived AGC.
Appearance is important, for this reason I built the radio to look like something out of the 1950’s or early 60’s using military surplus chassis, knobs, lamps, connectors, and external parts.
Although the superficial exterior components leverage military surplus, the insides are readily available in mail order electronics catalogs.
