Re: Amateur satellites and disasters...



Hi All,
This "rich American worked AO-40 witha 70 cm helix on a stepladder, $2.00
worth of aluminum a $20 6' ladder, and $ 5.00 worth of copper tubing.
Receive used an abandon Prime star dish, a modified C-Band  LNA a conifer
MDS converter two old 2 M all modes an home brew  up converter and a
salveged 70 cm amplifier, less than $ 500 invested, and I work stations from
Japan to Germany. I also learned a lot doing the construction of the system.
