A piece of history

One of my first professional jobs at Pye Telecom was re-banding the PF70 to the band that included 2m. 

In those days crystals were quite inexpensive, so I made one with crystals for the fledgling GB3PI, 145.50MHz simplex and 145.55 MHz simplex. I think I added a 1750Hz tone burst as well.

They were bodyworn radios with a LS/mic. A handheld version was also made.

These radios are hard to find these days and batteries rarely work.
