N0JY turned over operation to N8MH and AMSAT Operations in a QSO on the AO-91 repeater during the pass over the Eastern U.S.
N8MH responded and declared AO-91 open for amateur use!
With the successful launch and impending activation, of AO-91, now is a good time to join AMSAT and receive a digital copy of "Getting Started with Amateur Satellites" for free! Visit https://t.co/XkA44YOTsR and help us Keep Amateur Radio in Space. #amsat #arrl #hamradio pic.twitter.com/Wakzm095TS

A dummy load is a piece of equipment which allows transmitter testing and adjustment with minimal radiation of RF energy.
Most dummy loads are constructed using non-inductive resistors and utilize various heat sinking methods, ranging from passive air cooling (e.g. Elecraft DL-1, MFJ-261) to submersion in non-conductive oil baths (e.g. Heathkit Cantenna, MFJ-250), to dissipate the transmitter power.
RadFxSat (Fox-1B) was sucessfully launched on a Delta II rocket from Vandenberg Air Force Base at 1:47AM PST on November 18, 2017, and has been heard over Europe.
#Fox1B sound & Alive over Europe 😀😀 well done to all the teams involved #amsat #hamr @AmsatUK @AMSAT pic.twitter.com/2w07c5T5Ne
