If Galaxy 15's transponders are all of opposite polarities, then wouldn't
the potential interference be cancelled-out by around -60dB due to the
polarisation mis-match on both the uplink and downlink paths?

Ah, I knew it couldn't be so simple. Thanks for the insight into this aspect
of satellite construction and operation.

John, N4QQ is in PJ2 (Curacao) for an HF contest this weekend, and has
his Arrow, and the AMSAT DXpedition loaner D7 with him. He plans on
being active on the FM satellites Thursday, Friday, and the following
Monday and Tuesday. No activity is expected over the weekend. John is an

I just wanted to give a little status update on AO-51. We are currently
running just the normal V/U repeater, with PL enabled, and the power
management software running. The power management routine adjusts the
power output in three stages based on illumination state and battery
voltage. Tonigh

teachers participating in the teachers institute at the New Mexico Military
Institute! The reviews from the teachers were very positive and summed up

G-15 and AMC-11 are opposite polarity, and most of the AMC-11 transponders are
pretty wide, and the main ca

Sounds great and a lot of fun Dave. If Texas, board of education rewrites the
13 colonies and adds Alabama, I would be glad to help.

It's that time of year again. Last year Tim, N3TL headed up a group of
operators from the 13 original colonies. Fortunately for him, he recently
started a new job, and will be unable to organize the satellite stations for
the 4th of July event. After emailing Ken, the organizer of the event, I was
