Pye PF8

Many years ago I was part of the design team working on the PF8 transceiver. In its day (before mobile phones) it was a radical design and probably "ahead of the game" as they say. It used a radical internal antenna (a skeleton slot) which I designed along with the TX audio. In those days we had no real competition and it took a long time to overcome the noise issues with the DC-DC converter. It was the first Pye Telecom unit to use a multi-layer PCB. It became famous as the transceivers used in the TV series "The Professionals". PF8 units are very hard to find these days, but some have been converted to 70cm amateur use.
