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!

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

satellite demo & presentation, Thursday evening (19 March)
by Patrick STODDARD (WD9EWK/VA7EWK) 18 Mar '09

18 Mar '09

Hi! I will be giving a satellite-related presentation for the ThunderBird Amateur Radio Club in Glendale, Arizona, on Thursday, 19 March 2009. The meeting is in the Snell Building on the campus of the Thunderbird School of Global Management, room 28. The campus is on the southeast corner of 59th Avenue and Greenway Road - grid DM33vo. The meeting starts at 7.00pm (0200 UTC), and my presentation will be after the first half of the meeting - approximately 8.00pm. Before the meeting, I will have a demonstration on AO-51. The satellite will be in range between 6.33 and 6.47pm (0133-0147 UTC), a high pass to my west. I will be on the 145.920/435.150 MHz repeater, to allow anyone watching my demonstration listen in with a 2m/70cm FM transceiver. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

old satellites
by w7lrd＠comcast.net 18 Mar '09

18 Mar '09

Hello I believe this subject has been kicked around on this BB before. It did generate some creative thinking. Given all the satellites up there and all the varied uses of them, eventually some of them get compromised for whatever reason. Is there any way any of these old relics can be reprogramed, used or otherwise "adjusted" to suit us? We don't need a real good S/N ratio to make us happy, and we are pretty good at cobbling together whatever we want. We have some very informed and smart people on this BB who know. 73 Bob W7LRD Seattle

Tranzit-B telemetry system on ISS
by andy thomas 18 Mar '09

18 Mar '09

I've just come across the following interesting references on space ref to what seems to be a VHF telemetry channel (bio/medical monitoring?) "...including VHF/voice & biomedical electrode belt and *telemetry hookups via the BSS (later by the wireless in-suit Tranzit-B radio telemetry system) for vital signs and equipment monitoring". http://www.spaceref.com/news/viewsr.html?pid=30763 and: " [The suited run requires wireless Tranzit-B suit radio telemetry on both semisets (activated: 2:56am) and temporary deactivation of the Russian VHF channel 1 (Very High Frequency, Russian: UKV1, for ultra-shortwave) to avoid interference from extraneous radio stations to the Orlans while over Russian ground stations (RGS, DO 3/4). All EVA preps were monitored by the ground via audio, the reason for the early morning time of the training run. Tranzit-B TM was turned off at ~3:10am EST.]" http://www.hq.nasa.gov/osf/iss_reports/reports2008/12-19-2008.htm My questions are: what is the TRANZIT-B TM system, how close is it to the 2m channels, what is the TLM data modulation and breakdown? 73 de andy G0SFJ

"Mobile" Operation
by Kent Frazier 18 Mar '09

18 Mar '09

I've heard conflicting things, so I'd like to see what the consensus is here. Since my rig is mounted in my car, I've been told I should say "mobile" when ever I attempt a QSO. Some of the reasoning is that others will understand my "limitations" and try to work me. On occasion, this seems to have been the case. Others have told me that I should only use "mobile" when the vehicle is actually in motion. What say you all? 73, Kent K5KNT AMSAT #36765 ARRL

Defective W32A 4 Sale
by Sebastian 17 Mar '09

17 Mar '09

This is a long story, I'll try not to get into too much detail, and please any responses send them directly to me. I have an Icom W32A (dual band full-duplex HT) package for sale. It includes a wall charger; an off brand Master Charger 1a (drop in charger); BP-173 9.6v 650mAh battery; 9.6v 1100 mAh W&W battery; Icom antenna and original manual. I bought this recently at the Orlando hamfest, and it seemed to be working fine. It was a package deal, so I sold this to another ham who found the radio had problems when it was received. The other ham opened up the radio, and found a ribbon cable which goes from one part of the radio to the other, was loose, and missing a small plastic connector which holds it in place. When the ribbon cable was moved to the right place, the radio worked perfectly. The other ham broke the cable, and then tried to 'fix it' and the radio no longer turns on. I don't want to deal with this anymore, and would prefer to sell it as- is NOT WORKING. I'll sell the entire package only for $110 shipped. This is good for parts, or perhaps you can repair it. Again, please respond off the list. 73 de W4AS Sebastian

The Goce Satellite Ion Engine
by Bill Ress 17 Mar '09

17 Mar '09

Following up on David's (G0MRF) post about the ion engine, the ESA Goce satellite mission, due to launch next week, uses a nifty ion engine which you can see at: http://news.bbc.co.uk/1/hi/sci/tech/7935621.stm I believe these engines will soon become "practical" for use in satellite orbital modification. David presented a fine paper at the 2008 AMSAT Symposium in Atlanta showing how it would be possible to launch (relatively inexpensively) to LEO and then over time, using small thrust engines, modify the orbit to MEO. He also shows how the MEO orbit could provide a significant portion of a HEO's orbit visibility time. Possibly a reduced cost way to achieve extended satellite visibility at a price tag much less than the $8 to $10 million dollar GTO launch cost. If any of our members/readers have leads/contacts with folks doing ion engine development work that might be looking for a satellite test vehicle, please contact me off list. Regards...Bill - N6GHz`

I'm not sure how active FN01 is regarding satellite work, but I will be spending a week in that grid next week for work. If anyone needs FN01, I can be very easily convinced to take an HT and antenna with me. I do not believe I have the grid worked myself, so it might be rare on the birds.

Hi. ESA will use the usual 2G / 2.2G ish space communications band for GOCE. The modulation format and data rate will be very different from anything that we are familiar with. The uplink will send commands to the spacecraft and the downlink will send back science data but It's highly unlikely that signals can pass through or that the TX and RX can be moved to 2.4 GHz. >And thinking further, for these satellites could amateur radio gear be >carried so that it could be activated once the main mission is complete? >Doing this over a number of years would provide a ready made supply of >new birds over a period of time. This however is a very practical idea. Right now AMSAT members are building / designing a communications system that will be launched on the ESA educational satellite ESEO. When the science mission is over it will switch to amateur use and hopefully provide a good service for many years (touching wood for good luck as I write this) ESEO is planned to be 75kg going to LEO. 73 David

So . . . As I really only have a hand-held radio when I'm in the car, that might be considered porta-mobile. But since I often have to stop and hang the antenna out the window, would that be considered psuedo-mobile ? Which raises another age-old question - "If I forget to key the mic while talking, but my wife isn't around, - am I still wrong ?"

If you're not operating from your station address, and your entire station is not capable of being fully operated whilst moving, then you are portable. If your station is completely operable whilst you move your "shack" at the vehicle's (or your feet if walking) normal speed, you are probably mobile.

N3TL/portable South Carolina
by n3tl＠bellsouth.net 17 Mar '09

17 Mar '09

Hey everyone, What a hoot that was! If any of you are thinking about making a drive to activate a not-so-active grid or a not-so-active state ... go for it! You will have a blast. I did. >From here in northeast Georgia, South Carolina is closer than Ham Radio Outlet's Atlanta store. Last night, I drove up U.S. 441 to I-85 and headed north to the state line. I found a couple of really good locations very close to the border and just off the interstate. I chose the South Carolina Welcome Center at I-85 mile marker 1 last night because (1) the pass would be after dark and the center is very well lit, and (2) it was rainy and foggy. I figured the light and security of the center would be nice to have. They were. My home grid, to six characters, is EM84ha. On this pass, I operated from EM84ll. This was a busy pass of AO-51, and there were multiple Mexican stations operating portable from different grids. In spite of that, I made a personal high of 11 contacts on the pass, with: AA5PK K8YSE - EL98 N5AFV K8YSE - EN91 KB0RZD WA5KBH N1RCN N9AMW WA2S K5KNT K8NWD Thanks to everyone on the pass. It was great hearing all of you and working so many of you. This location is a good one for working passes to the west, and I'll be using it again to activate South Carolina. QSL cards will be on the way in the next day or two. No return card is necessary. 73 to all, Tim - N3TL EM84ha

How much Precision for QTH?
by Kent Frazier 17 Mar '09

17 Mar '09

Hi all, I was wondering how much precision is needed when indicating my QTH on a QSL card. Since my station is currently my mobile rig, mounted in my car, I sometimes operate from different locations. Mostly I operate from the driveway of my home, but I have also operated from my daughter's elementary school and my work parking lots. Both of these locations are within a 2 mile radius of my home. I know if I were in a different grid square I would need to indicate that, but when operating within the same grid and even the same subgrid how precise do I need to be? 73, Kent K5KNT AMSAT #36765 ARRL

Trevor M5AKA said : > Does anyone know if the camera is connected via cable > or do they make use of a WiFi connection ? We'll assume you are speaking of the connections on ISS, as it is most certainly wireless back to earth. TDRSS tho, not LinkSys. They have several new HD video cameras mounted outside, in addition to several indoor cameras. The Ku band downlink carries 4 simultaneous video channels, as selected by ground control or crew. I'm not sure why this is considered new, as it seems like the same thing they have been doing during crew sleep - showing lots of outside camera views on NASA-TV as streaming video. I think maybe there is a new URL, it's just that during Joint Ops they are showing Mission Coverage, same as on the main public channel. AhHa - looks like http://www.nasa.gov/multimedia/isslivestream.asx by itself will kick open a Media Player window. Maybe after this shuttle mission this new URL will not go back to the regular public channel content. I love watching the earth ball rolling underneath ISS, and hope that this new URL will give us more of that, and less 'NASA Edge' . . .

One solution may be to put the ISS in a 1200 km orbit and thus above most of the debris that originates from decaying sats and debris in 500-1000 km orbits. The big drawback is that it would cost more per kilo to get payload up there but once construction is completed there shouldn't be the need to ship up so much stuff. 73 Trevor M5AKA
