I find about the same. If you have a good receiver on 222 MHz, a preamp in the shack does nothing except raise signals and noise all the same 20 dB. It would take a pretty bad receiver to be helped by an in-shack preamp on this band. But...some receivers may actually be that bad! Nothing against preamps, but the SS brick amps that include them all seem to use miniature, sealed relays to switch them in and out of line (they use those for T/R changeover also) and the damned things fail. It's counterintuitive but the "receive" contacts are the ones that frequently fail (not the "transmit" contacts that handle the amp's output power), probably because they never conduct any current (well, maybe a microamp or something, but not enough to prevent surface oxidation). First thing I do with any of these amps that include a preamp is open it up and bypass the preamp and its relay system entirely with a short length of small coax.
