Internal preamp

[nfsus]

I want to wire in a homemade preamp. They used to install a 4 wire in those years ago. I'd like to find the wiring instructions. I'm almost thinking it was power ground and then tied into the rf gain.

A Receive Pre-Amp you can build!

All, Rambling through my junk box, I ran across a receive pre-amp I picked up many years ago (Don't remember where). It is a very simple circuit that I have tried to draw although I am sure it is not to engineering standards! I did install it in a Cobra 29 many moons ago that was in my service...
