The March newsletter is out and our speaker for this month is none other than our own Antonis AA6PP, and maybe James KM6ASJ, who will be talking about February's Kaiser event with DMR. DMR is in our future, so don't miss out on this introspection on using new technology for large coordinated events. If you have not received the newsletter yet, you can find a web copy here.

Bias-Tee Power Delivery
w/ Jeffrey KI6SGV

Powering a preamplifier on your tower is pretty straightforward, right? Just run a power line up the tower and plug it in! Well, that's more cable to run up the tower and more cable to maintain. You've already got perfectly good coax going up the tower; why not just use that? Well that's exactly what we're going to do! Using a bias-tee (or bias-T) SFRC President Jeffrey KI6SGV will tap off a DC current sent over the antenna coax to power a preamplifier in a satellite rig. Come see the design, build, advantages, limitations and flexibility (and great price!) of this kind of power delivery system. With a little luck we'll have a working unit for a demo!

Hacking Satellites & Antennas in the Urban
w/ Kaitlyn KN6MAN

Join the San Francisco Radio Club on Friday, January 20th at 7:00pm to be updated on Club business and activities followed by a presentation.
TOPIC: Amateur radio and hacking have a lot in common: tinkering, building, breaking, DIY, doing what can't (or shouldn't) be done! Kaitlyn KN6MAN has a fondness for hacking satellites and has taken lessons from DIY antenna building and city living to build not only a satellite tracking rig, but also a stacked yagi array inside a dish antenna for space and terrestrial communications. See how she built it and what curiosities she finds with it.
