Re: URGENT! - UWE-1 team needs help!



Dear Radu, I listened for UWE-1 from 22:31 to 22:44 as predicted by 
Object 28893 (D) and I did not hear any signals at all.

The last signals I heard was at 08:56 to 08:58z (29th) and both packets 
were too weak to decode. I have a recording and replayed them many times 
to MixW2 and my TNC but unable to decode anything. I didn't record the 
next pass.

Sorry I couldn't provide better news.
Regards
Ian Ashley, ZL1AOX
