    Single 4CX250B base amp for the masses!

    Thank you Nomad. This not something I will be dedicating all my time on at "this moment". But I will be doing this on my next Pride DX-300. Like I said, I was given a bunch of parts. I am going to have to go over some of these boards. I have 2 Input/Relay boards that are missing some of the...

    Mobile End Fired Phased Array Antenna

    I've made a Moxon for uhf. the concept is a folded dipole with a folded reflector. Can't think of how you would use that vertically as a mobile antenna. No doubt it was a heck of alot easier to tune then a standard dipole without a balun. BTW tons of Moxon calculators on the internet.
