[TNham] [Fwd: UX-4 Results]

[Greg Williams]

Hi All,
     The ux-4 results are on the www.utarc.org main page.  The beacon 
continues to be recieved in La Crescent Minnesota and Okalaska Wisconsin 
with regular reports still coming in, battery voltage is at 11.3, it had 
dipped down to 10.5 at high altitude, I think the styrofoam has provided 
good insulation.  It's probably hanging in a tree, and will continue to 
transmit through tomorrow probably.  I'll have some pics online later of 
launch, it was good, uneventful, and the clear day allowed us to watch 
it almost 20 minutes into the flight with binoculars.  Bill Brown 
predicted our mission data as reported on the web page, and his 
predictions match our signal anomalies that we interpreted as burst and 
then landing perfectly, so the landing data should be reasonably 
accurate.  The 20m transmitter performed great, a 597 throughout the 
flight, though the antenna geometry changed like a pendulum, and caused 
the frequency to drift back and forth all the while it was in air, 
though not enough to impede decoding.

This design, perhaps with some modification to avoid the effect of the 
antenna geometry affecting the frequency, looks good to go for future 
missions, a fully digitally interfaced CW transmitter at nearly 1 watt.
Thanks,
Dan
