[amsat-bb] OZ7SAT? Off the air?

Does anybody (Ib ;) ) know if OZ7SAT is off the air? I haven't seen any telemetry updates in over a week. http://www.amsat.dk/oz7sat/tlm/ Thanks, -- Mark L. Hammond [N8MH] ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

Hello, I've been asked by a club member if anyone has any experience using an M2 VHF/UHF Polarization Switch, and what their opinion of it may be. I can't seem to find any reviews on field performance, thank you. 73's Pete WB2OQQ www.massapequanyweather.com

Nigel - There are lots of lots of reasons ... 1. All link budgets use a path loss calculation that's also referenced to an isotropic radiator. If you use antenna gain referenced to a dipole, you'll have to add back the gain of the dipole (referenced to the isotropic radiator). 2. It's the
