Years ago, I worked on the Pye PFX. An old friend has just pointed me to a PFX service manual for sale on eBay.
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.
