Radio ham launches over 500 High Altitude Balloons

The ARRL has made available an article about *Bill Brown WB8ELK* which
appears in the May 2017 issue of QST

Bill has launched over 500 high-altitude balloon projects over the span of
30 years. For his first flight on August 15, 1987, Bill designed a remote
viewing platform, using a P.C. Electronics Amateur TV transmitter on 434
MHz, and a 50 mW, 2-meter FM beacon to track and direction-find the payload
(this was, of course, before GPS).

“Amateur TV stations across the midwest had beautiful reception from this
tiny, 1 W amateur TV transmitter as far as 250 miles away,� Bill explained.
“The 2-meter beacon was heard over 400 miles away.�
