[amsat-bb] [Video] Preamp test in front of radio / satellite ground station build update

[Hasan al-Basri]

ARR Gasfet preamps for 2m are every bit as good as the SSB Electronics
ones. The issue is power handling. The SSB units handle high power, the
limit for a switching preamp on ARR's (that were still available) was 25
watts. I believe they stopped making the 160w jobs.

I think you can still get the ARR 25w RF switching preamps. I looked last
month and they were still available, but perhaps they have thrown in the
towel.
