The microwave bands are an area of amateur radio that I have never got seriously interested in, although we can only do so much I guess. Quite a
few people are doing ATV at 5.6GHz using low cost modules.
Years ago I bought the "Backscatter compendium". This is now available free
to download.
See https://www.microwavers.org/backscatter.htm .
Years ago, I worked on the Pye PFX. An old friend has just pointed me to
a PFX service manual for sale on eBay. https://www.ebay.co.uk/itm/Pye-PFX-Pocketfone-VHF-UHF-FM-Transceiver-Reference-35-06-2021-/133800248662?_trksid=p2349624.m46890.l49286
I have just spotted that it was my personal copy with my name on it!
No, I shall not be bidding, HI.
The PFX was widely used by the UK police and some were used on 70cm. It was
the first synthesised portable Pye Telecom ever made. It had a few false starts, but was very successful in the end. The PF85 was a crystal
controlled handheld using many of the same modules.
