Good Pass of International Space Station with Plenty of Operators!
Today morning there was a good pass of International Space Station with maximum elevation of about 24 degrees, on the Western side, starting from 0147z. I was quite happy to hear several VU stations and work a couple of them. Prior to the pass I had kept my Moxon Yagi for satellite operations, at a fixed small elevation, in the direction of maximum elevation of the pass. I use the live display on Argentinian Amsat satellite pass web page to manually tune Doppler in my IC 2730 radio during the pass.
You can hear the audio recording of the pass International Space Station in which I could hear many amateur radio satellite operators from this region, at the end of the video. Hissing noise heard in between is the open squelch in the radio meant for picking up weak signals from the satellite. With my fixed elevation azimuth Moxon Yagi, I can hear only the central portion of the usual 10 minute pass of International Space Station. As the satellite is moving continuously as well as spinning and tumbling in orbit, orientation of satellite antenna with respect to my antenna changes, causing drop in signals intermittently. Ideal setup would be a cross Yagi with circular polarization, along with automatic antenna rotator and Doppler tracking, which will be quite expensive.
