[amsat-bb] Do-64 signals.

Hi all,

DO-64 pass over ZL/VK at 2211UT showed an interesting effect. I was in contact with VK2AYE and VK2ZAZ when the signals effectively disappeared some minutes before LOS. VK2AYE checked the beacon and reported that it was badly distorted at that time. I noticed the same effect on a previous pass on my own downlink and also saw another pass when the beacon was distorted for about a minute. The effect is identical to the distortion seen on the data channel and occurs when Delfi is South of ZL and starting to loose the sun. It lasts for about a minute or so and then recovers.
