I have one of the classic elevation rotors sitting on the shelf one click short of the land fill. I have most of the hardware and the service manual. Notable missing is the terminal cover on the rotor motor. Any offer that covers the shipping and it is yours. k8tl(a)earthlink.net

Yaesu G-5500 azimuth issue

by Jeff Griffin

After a power failure the other day my G-5500's azimuth rotor is dead. I searched for a test procedure, but can't find it. I have one at my Florida home, but that won't do me any good up here. If you have one, the procedure to test from the rotor control box cable please send me one. I switched the cable from az to el and the problem stays with the azimuth part of the rotor, the box appears ok. Thanks. 73 Jeff kb2m

D-SAT RX Opportunity over U.S.

by Scott

Hi everyone. Today I was included on an email from Alessio, IU5CRE, who is part of the D-SAT project team. (https://www.dsat.space/radiohams) Previously, it appears that the majority of the transmissions from D-SAT occurred when the satellite was over Europe. Alessio indicated in today's email that commands have been uploaded to D-SAT that may result in transmissions tonight over the U.S. around the UHF downlink of 437.505. He specifically mentioned 437.503 & 437.509. First, here are the approximate UTC times when D-SAT will be over parts of the U.S. tonight (UTC date: 28-July-2017): East - 0152 utc Central - 0326 utc West - 0500 utc If D-SAT is not in your tracking software, here is a web-based tracking site: http://www.n2yo.com/satellite/?s=42794#results And as always, there is good info on the DK3WN site at: http://www.dk3wn.info/p/?page_id=29535 -and- http://www.dk3wn.info/p/?cat=439 So I don't know what, if any, data we might see tonight but since this could be a limited opportunity on this side of the world, I wanted to share what I knew with anyone on this mailing list that shares my interest in cubesat telemetry. -Scott, K4KDR

INTERMITTANT DOWNLINK HEARD - CAS-4A transponder freq

by christy hunter

to All, this is to confirm my status report on the website, (in case you think it was a mistake) on July 27 2017, at about 0047UTC I could hear my downlink, although intermittently, during a pass of CAS-4A (using the published frequencies). The downlink had good audio (loud and clear), and I could only hear a few words of my transmission at a time. I was able to sustain for only a portion of the pass. Using 5Watts into a M2 16 el cross element circular beam. (436CP16). This pass did NOT coincide with any of the XW sats. 73, Christy KB6LTY, DM14 --- This email has been checked for viruses by AVG. http://www.avg.com

Maine grids

by Scott Richardson

I will activate up to 9 Maine grids over the next 3 days, including FN56, FN57, FN66, and FN67. Most activity will be Sunday and Monday. I will be on FM and linear sats. I have no set schedule and more to do than operate satellites, but will make a solid effort to fill holes in your grid maps. QSOs will be uploaded to LoTW after the trip using N1AIA. 73, Scott N1AIA
