[amsat-bb] Landwehr Pre-amps

[Paul Andrews]

Hello Satellite Friends,

I have two (2) Landwehr 2M RF switched (VOX) receive pre-amps.  Both
are in good condition, with power / PTT connectors.  NF 0.6db / 20db
gain / unconditionally stable.   Waterproof mast mount.

150w VOX and 750w is PTT switched.

I will provide factory user manuals and schematics.

Preamps are available immediately.  Email w2hro.fn20 at gmail.com

They were working when removed from service about seven years ago, but they have been sitting around a long time and I have no means of testing them at the moment. Strictly "as is." They *DO* have the rare power/control cable connectors with them.
