Re: Comments on UO-14



 Hi Jonn...

Just got back from trying the 1518 UTC UO-14 pass, and found it even worse
than yesterday's pass.  This one was at something like 85 degrees--high
enough that I usually at least hear myself with the HT and 19 in. flexible
antenna, but no luck.  As well as being totally saturated, there was CW
(from one of the FO-birds?).  I did here you today, though.  I think I heard
your mobile only momentarily on the 1547 pass yesterday.  Were you mobile
today?

Yesterday, even Mike N1JEZ was being stepped on!

Good luck to the fellas trying the transcon. QSO on the next pass!

73,
Frank
