I am trying out one of the ARR mast-mounted pre-amps on 432. I just listened to the SO50 and AO51 passes. I swear I cannot hear any difference, ok maybe just a bit. But not much, not enough to make a difference.

With the receiver in SSB mode, antenna pointed at nothing, you should hear a substantial increase in background noise when the preamp is turned on. S-meter should jump. If not, the preamp ain't workin'.
