[amsat-bb] Noise, distortion and fading on AO-92 L/v downlink

[Ronald G. Parsons]

To my ear, the L/v downlink just “sounds” more distorted and noisier than the U/v downlink. Perhaps something is coming in the L port or is internally generated. The downlink path in my radio is identical in L/v and U/v. The rapid fading last weekend was very noticeable at lower elevations and was close to a 30 sec period. At higher elevations, it was not noticeable. I’ll try to remember to screen capture the downlink waterfall next weekend.
