Pye Telecom PF1 NOT amateur radio

One of my first professional jobs was to convert the PF1 units to 12.5kHz channel spacing. This was for Mike Gotch who I heard much later was M0IMG. I think this was a test of my capabilities. 

Mike took early retirement to look after his sick partner. He sadly died later following a stroke.

PF1 units were low power and some were converted to 70cm.
