Presentation/demonstration tonight - report
by Patrick STODDARD (WD9EWK/VA7EWK) 20 Mar '09

20 Mar '09

Hi! Thanks to all the stations I heard and worked on the 0133 UTC AO-51 pass this evening. I was standing outside the meeting room on the Thunderbird School of Global Management campus in Glendale AZ (grid DM33vo), and the demonstration took place just before the start of the ThunderBird Amateur Radio Club's monthly general meeting. I also gave a satellite/AMSAT presentation during the meeting. For the AO-51 pass, I worked 13 stations from central Mexico up to Alaska, and as far east as Winnipeg and Memphis. Thanks to all for the QSOs, and my apologies to N5JDT and VE6RVT/W7 - I heard you during the pass, heard you again when playing back my recording to make my log entries, but did not work you in there. I also heard from a couple of others who heard the pass, but could not get through themselves. I appreciated the crowd that showed up for the pass, and the variety of locations for a predominately western North America pass. I gave a presentation for this club in March 2007, followed by an on-air exercise for some of the club members who assembled their own dual-band Yagis using the WA5VJB "Cheap Yagi" design complete with diplexer in July 2007. I've been invited to their hamfests for 3 consecutive years now, in January of each year, and appreciate the hospitality of the club and its membership to have me be a part of their meetings and hamfests over the past couple of years. 73!

What's up with that ??? But, there she was - right on time. Got the full 2 minutes to watch. And 11 degrees looks higher than I was expecting. The crew got the S6 truss installed ok, and they expect to get the new solar panels deployed tomorrow.!. I'm sure they'll have the radio back on soon.

Fixed my converter! I'll be back on the next pass. A lil water got in there, condensation or leakage. I put vaseline around the rubber O ring on the cover to keep that from happening again. Michael Heim Chief Engineer, Forever Broadcasting New Castle PA WKST WJST WWGY 814-671-0666 ARS KD0AR

Re: AO-51

19 Mar '09

Did I miss a mode change? I thought SSTV started on the 23rd! On this last pass of AO-51 on v/u, (145.920/435.150) we were treated to sporadic SSTV and someone saying "test, 1,2" repeatedly! On the basis that he was ignoring the QSO's that were trying to go on around him, its save to assume that he couldn't hear his own downlink! What goin' on? -- David KG4ZLB www.kg4zlb.com

Yeasu 5400 rotator help.
by boprie＠aol.com 19 Mar '09

19 Mar '09

Hello We have two Yeasu 5400 AZ EL rotators with the associated controllers and the same problem. Both are about 15 years old and generally work. There is a procedure to set it up that calls for the operator to drive the AZ and EL to the 360 and 180 to set the full scale deflections. We can do this and see the required 4.5VDC on the two appropriated pins in the back. When we drive the AZ and EL back to zero, it is typically short about 10 degrees. We have attempted this adjustment several times to find the happy medium between the few adjustments but we can never get the full span. Does anyone know if there is something inside the control box we can change(or modify our set-up procedure) to get a fuller span on the AZ EL meters? In looking at the schematic, and also on the inside, we didn’t find another hidden pot to do this. If anyone can help, they also email me directly if they wish at boprie(a)aol.com and also Boprie(a)umich.edu. Tnx and 73dB de WS8P G'day

AO-51 mode S
by w7lrd＠comcast.net 19 Mar '09

19 Mar '09

Mode S down link sounds great. I almost had the bird to myself I caught a station with NUK then nothing. Rather tricky tracking the fast moving 51 with a 3 foot dish and chasing doppler all by hand. Nice to know my old AO-40 (sobsob) S band stuff still works! Get out that "old" S band gear! 73 Bob 7LRD Seattle
