Topband: Topband Phenomenon

[terry burge]

Maybe the International Space Station could reflect a 160 meter signal or reradiate it. It's larger than a football field. Just a thought. Let's see, people could use the space station to bounce signals off of. Another reason to keep it from falling in the Pacific Ocean someday.

You could tune to WWV on 20 MHz at a time of day when that was above the MUF.  When the Echo satellite came by, WWV would pop up out of nowhere for a few seconds and then disappear again.  To the best of my knowledge, the Echo satellites are long gone; but this sounds like a similar phenomenon.

I struggled to get F4HEC's call because he was so weak. He persisted and I finally got it. He was the first European that I heard in the contest. When we finished the QSO, EI0R dumped his call and he was 579. Unbelievable because I almost never hear Europe on 160 CW. I gave him a report and turned it back. By then he was barely copyable as his signal had dropped back down to the noise floor and I never heard him again. I managed to work several other Europeans whose calls I had to work at digging out. I would say conditions were generally good for me to hear those European stations, but the momentary signal from EI0R was very strong and unexpected.
