Yesterday, I received a RF Concepts 4-310 linear amp in the
mail. Its used but amp works fine on UHF. With 30w drive from the
venerable FT-736R I'm getting 100w on 432.200 and 130w* on
446.00. *Turning down drive to keep at 100w.
The internal preamp does not appear to work and only adding more
noise but the is non-issue with the fine receiver in the FT-736R and
the fact I have 432 preamps for use with yagi's once I fix SWR issue.
Current using the ARX-270 11 dBd base vertical antenna. I have a
11-element yagi at 58-feet but line has high SWR somewhere.
Running 100w should make UHF doable with stations in Anch. and valley.
