Would greatly appreciate some help trying to set up my LVB and Yaesu G5500 Had just a few questions as to the set up types I should use for the LVB settings: >> is this rotor considered >> >> a 360 degree max az rotor or 450 South CCW = FEN >> >> or >> >> 450North CCW = FEE >> >> second question: >> >> is this considered >> >> a South CCW stopping rotator, ‘F’, ‘S’, . or >> For a North CCW stopping rotator (default), ‘F’, ‘N’, . >> >> thanks cc amsat-bb(a)amsat.org date Sat, Nov 26, 2011 at 9:18 PM subject Re: [amsat-bb] Re: quick LVB cal question mailed-by gmail.com Important mainly because of the people in the conversati thanks very much for trying to help unfortunately it really wasn't what I asked. hope someone out there might be able to help a newbie out thanks N2EHG Myles - Show quoted text -

DEAR AMSAT MEMBERS. Please help me. I have yaesu g-5500 rotator. for 1 year. it works good but now it doesnt rotate in elevation axes. I press the up and down switches in controller but there is no change in meter indication and also no change in antenna position in elevtaion axes. in azimuth it rotate true. but the calibration is not true. i mean that when antenna position on the roof change 180 degree the azimuth indicator in the controller showes 360 degree change. I really confuesed. I dont know what is problem . it works good from last year to now. I chech all cables and there is not any problem. any help would be gratefullu appreciated. Im looking forward to hearing from you. Best Regards.

Fw: ARRISat-1/RADIOSKAF-V/KEDR
by Farrell Winder 28 Nov '11

28 Nov '11

No success today Nov 28. Will set up again tomorrow Tuesday Nov 29 for the AOS 15: 04 Z Cincinnati pass. From: Farrell Winder Sent: Sunday, November 27, 2011 7:31 PM To: AMSAT Subject: ARRISat-1/RADIOSKAF-V/KEDR All, With the research and recent "heads up" by Mineo Wakita, JE9PEL, Allan Biddle, WA4SCA and Clint Bradford, KCLCS it appears there may be only a few weeks left to receive and experiment with ARISSat-1/RADIOSKAF-V. On Monday Nov 28 I will be set up to receive voice, CW and SSTV via the transponder on 145.930 MHz +/- doppler. This will be on the AOS starting at 14:47 Z pass over Cincinnati. This pass may be too soon after the eclipse so the sat may not be activated. If it is active, I will try to send a couple of SSTV R36 transmissions. I will be listening and looking for others to send also. Farrell Winder, W8ZCF Cincinnati, Ohio.

AO-51 S band test this afternoon
by Andrew Glasbrenner 28 Nov '11

28 Nov '11

I plan on testing the S band transmitter on AO-51 on the 2010Z AO-51 pass over the east coast today, and would like some volunteers to help listen for the transmitter. SDR receive capable stations would be even better since it may be considerably off frequency. I'll be commanding remotely, so will have limited receive capabilities, and do not expect to hear the UHF at all. If you could provide feedback via Skype, all the better. Please contact me directly if you can help listen. 73, Drew KO4MA

Elana-3 objects
by g.shirville＠btinternet.com 28 Nov '11

I am intrigued that the six objects from this launch seem not to be separating as far/fast as I would have expected. After 4 weeks from launch they all seem to be still close together. Do we know if the separation springs were deliberately low power or what the separation speeds were intended to be? many thanks Graham G3VZV

Did anyone happen to "re-create" the photo of Lance Ginner holding OSCAT 1 under his arm at the AMSAT Symposium? What a great "then and now" opportunity! Clint Bradford
