K7UGA - rained out tonight
by Patrick STODDARD (WD9EWK/VA7EWK) 15 Feb '12

15 Feb '12

Hi! Sorry for another wave-off. For the first time in a little while, rain hit the Phoenix area. I won't work any of the passes tonight, and - weather, and work, permitting - I am still planning to try SO-50 tomorrow around midday. Since I'm not working passes tonight, I may try to at least do one SO-50 pass in the evening (early Thursday, UTC). 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Fully automated mode now.
by Andy Kellner 15 Feb '12

15 Feb '12

So now with the NORAD TLEs out (doesn't really matter which one you choose, as long it is not 2012-006A and 2012-006B) I've switched my station into fully automatic MaSAT-1 tracking, doppler-correction, receive and decode mode. 4 hours left until first pass .. I 'll be sound asleep then. We'll see how it goes :) Andy - VK4HHH

K7UGA unable to work 1943 UTC SO-50 pass today
by Patrick STODDARD (WD9EWK/VA7EWK) 14 Feb '12

14 Feb '12

Hi! Due to work-related matters, I will not be able to get out and work the 1943 UTC SO-50 pass as K7UGA that I planned to do. I apologize if you were hoping to hear K7UGA on that pass. At this point, there are no changes to my evening plans for K7UGA on the VO-52 passes and an SO-50 pass at 0420-0433 UTC tonight. I'm still planning to work a midday pass tomorrow, at 1832-1845 UTC on SO-50. I'm hoping there are no other complications at the office that would keep me from going out. Otherwise, my daytime operating will start on Thursday before I head out to the Yuma hamfest. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

MASAT Client question
by John Heath 14 Feb '12

14 Feb '12

Hi, MASAT client working nicely, have captured a few frames this afternoon, but more by accident than judgement. The ARISSAT software was fairly tolerant of an off tune signal. How close do we need to hold the waterfall display to the frequency markers? If the MASAT team are watching the bb then congratulations. 73 John G7HIA
