5cm activity?

Anyone know if there's any weak signal activity on 5cm? Seems like an
interesting band because it's pretty close to 5GHz WiFi so I would think
equipment could be cobbled together pretty inexpensively. I know there are
a couple of Japanese satellites using it for downlinks but I don't know
about anything else.

Most of the activity has been surplus from the Telephone industry and their 6 GHz Microwave links that use to chriss-cross the US.  Mixers, filters, and the TWTA's.  Later the Solid State replacements for the TWT's.    For years we have considered 20 watt 6 cm stations to be the low power guys.

Kent,
Is there any 5760 MHz EME activity among the NTMS group?

Any idea if there are enough active stations around Ohio to be worth
investing in ?

I’m thinking that we could stir up some activity via MVUS with a design and some hardware. The 10 GHz activity just exploded over the last year, all just due to W8BYA’s efforts and promotion. I think he was as surprised as anyone by it.

I have a 5760 system. 6 cm is fun!
I used a dual frequency feedhorn (Downeast copper pipe design, easy to copy) 3 & 6 cm for one of my MACOM 2 foot dishes. Nice to do both 3 & 6 at the same time. I have a LNA/PA box that mounts with the dish and, of course, transverters made of surplus parts. I used FSJ-4 to feed the stuff up the tower, works great up to 10.4 GHzThe 10 watt Avantek amps can still be found. I did a conversion for 12 volts instead of -24 VDC like Ma Bell used.All written up long ago but around!I have plenty of bricks & Mixers, pipe cap filters will work. LNA designs are around or use a surplus amp.Biggest problem (not that big) is the reference crystal for the 6 GHz brick, not cheap or easy to get. Maybe someone with experience with some cheap 100+ MHz synth board can step up. I use low side injection 5616 MHz so I am at 144.1 for IF. The brick want to run high side so they would use USB for LSB. 5760.1 +145. ~ 5905 MHz. Should be no sweat to get the bricks going there! Just flips your sidebands, no big deal (also tune backwards...).I would be interested in playing if some folks wanted to get going here!73Jeff KruthWA3ZKR

Most of the activity has been surplus from the Telephone industry and

their 6 GHz Microwave links that use to chriss-cross the US.  Mixers,
filters, and the TWTA's.  Later the Solid State replacements for the
TWT's.    For years we have considered 20 watt 6 cm stations to be the low
