Hi Brian,

Sam, G4DDK, used to supply a PCB which was designed by GM3SEK. Here's a link to the article.

I hope that helps?

Hi Brian & Malcolm

Brian's module is the original Bipolar design which will give 13dB gain and 5W of clean DATV.

The GM3SEK boards are no longer available and are only suitable for the later MOSFET versions as are the Enigma PCBs.

The M57762 needs a 9v bias supply capable of up to 500mA whereas the MOSFET versions have bias supplies typically up to 5v and 1mA.
