23cm pre amplifier


After a few good days on tropo, this morning turned on the 23cm system to find that the pre amplifier had died.

This was a very good VHF Designs low noise high gain pre-amp.

Found that the initial device had gone short. Paperwork says an 'SKY67151', but looking closely it looks like

and is marked as a PGA-103.

Anyway, replaced it with a 103 but the pre amp is still very low (maybe no) gain.

So is there a good source of 'built' pre amplifers as the only ones I can see are the VHF design ones.

Eyesight now not good enough to try to build one of the DDK ones.
