[amsat-bb] Another newbie question

Again, thanks to all who are so supportive on this BB.

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. SO50 was not audible except for a brief portion of the pass here (my antennas are oriented horizontal at 30 degrees elevation, so that explains part of it).

Maybe the pre-amps really do their stuff on the passband birds? If I am wasting my time, I won't be embarrassed if somebody tells me so. Please, I am open to suggestions.
