Ran across an unfinished late-80’s project that would benefit from some time to poke around on: SHF Systems 144/902 MHz linear translator boards (3). Two boards are bare and a third has the oscillator built up that might be checked out with current test gear. Got these years ago from a ham who was cleaning out their shack. Design is by Richard Campbell KK7B. Curious to see if they can be salvaged. Documentation is at: http://01895fa.netsolhost.com/PDF/Manuals/SHF902.PDF #HamRadio #NotSDR #GarageFinds
