Last night's VO-52 pass (around 0315z??) was normal signal levels. Only unusual thing was about half way through the pass (as sat was over northern US) it seemed to be picking up some sort of interference ... I was watching the entire downlink passband on the SDR waterfall and there was a 10kHz wide swath of "static" type noise that migrated through the passband. As the noise moved through the center of the passband, it greatly reduced my downlink signals. I don't have any solid evidence, but my gut feeling is that the noise had nothing to do with VO-52 itself, but was instead something below that was transmitting hash on the uplink.
Overall, VO-52 works great for me, I use it every day or two on evening passes over northern California.

Just got off the 1235z (approx) pass and think the levels are quite low. It is me?
