controller for g5500 rotor
by James Brown 29 Aug '18

29 Aug '18

I am using a Fox Delta controller with my G5500. I am unable to calibrate it and make it function correctly. I do not see the controller that was available for years on the AMSAT website. What controllers are available to replace the FOX Delta? It will interface with sat32pc. Jim KI6WJ

antenna for 1.2 Ghz
by Philip Jenkins 29 Aug '18

29 Aug '18

For the VHF/UHF contest in September, there will be a group active locally...and running 1.2 GHz! Since L-band is active on AO-92, and I have the equipment - but no antenna - I'm looking for an L--band antenna that I can use both terrestrially and for the birds. My preference is for M^2, but both yagis on their website are a little larger than what I'm looking for - but they are still under consideration. Does anyone have recommendations for another brand, or have an appropriate one for sale? (I wish I had bought some of those loop yagis which were prominently displayed in Ball Arena at Hamvention in the early 90s...) (I'll be at Shelby NC Hamfest this Saturday (mostly at the AMSAT info table), in case someone is attending who has one and wants to bring it .) Thanks Philip N4HF

Tokyo Ham Fair
by Jeff Boyd 28 Aug '18

28 Aug '18

I would like to extend my gracious thanks to Keith C. Baker (KB1SF/VA3KSF) and his wife Kathryn (KB1OGF/VA3OGF) for chatting me up during the Tokyo Ham Fair this past weekend, where they had set up a booth promoting the next Dayton Hamvention. https://i.imgur.com/Po65neI.jpg As the former president and current treasurer of AMSAT, Mr. Baker was tickled that I had on my Fox-1A T-shirt (that I wore specifically for the occasion), and that spawned a great conversation about the current state of amateur satellites -- he pointed out that it was the move to the now-ubiquitous "cubesat" form factor that resulted in a Cambrian Explosion of satellite development. We also chatted about each other's backgrounds, and I got to interpret for some other interested Japanese attendees who had come over. Mr and Mrs Baker are both charming people and I hope they are here next year for the 2019 event as well! P.S. The JAMSAT (Japanese organization) booth: https://i.imgur.com/jE66KPc.jpg -- J.

satellite flexible rotor-section coax question
by David J. Schmocker 28 Aug '18

28 Aug '18

Hello: New to satellite communication I plan to construct a fixed station to work satellites. I am looking to identify best type of coaxial cable to run from my VHF/UHF antennas around az/el rotors to the preamplifier (located on the fixed mast/support). Most important coaxial cable requirements include: Highly Flexible (in upper midwest climate: temperatures range from 15 deg to +100 degrees F) in Repeated (continuous) flexing Low Loss (while super flex Heliax would be my preference, it¹s not designed for repeated flexing this application sees Full shielding (preserve S/N and overall system noise figure). I can compare the loss values from manufacturer data sheets; my main interest here is to learn what type of cable has withstood the repeated (continuous) flexing required to work satellites? What cable type do you recommend based on your experience? Thank you 73, Heliax Superflex? Times Microwave LMR-600UF? EcoFlex 15 Plus? Belden 9913Flex? Something else? David J. Schmocker, KJ9I
