Optical shaft encoders
by Robert McGwier 24 Mar '16

24 Mar '16

I would like to consider adding optical shaft encoders to augment or replace the hall effect sensors in use on an Alfa Spid az/el installation. We have the high resolution sensors and are experiencing some annoying anomalies that have been very difficult to trace and are detrimental to autonomous operation at our ground station at Virginia Tech. Any information or help would be appreciated. 73s Bob N4HY

Re: [amsat-bb] Ceuta & Melilla and Gibraltar this summer

Hi all, I am very sorry to inform you that after requesting formal permission to use VHF/UHF HAM satellite band from Gibraltar (by using the avaliable Gibraltar Regulatory Autorithy form they have send me by email to fill), they have denied me the permission to broadcast from its territory. They have told me that Spain licenses are not recognized by the colony. This may not affect other nationalities, so if you have a license from another country You can try if you visit the colony. Anyway, my main goal is to activate the autonomous city of Ceuta (DXCC entity Ceuta & Melilla) and all seems to be fine for this. I still can not specify the exact date but It will be in mid-August (probably between days 12-21). It is very possible that I will only be able to be in the city one or two days, but because this visit if flexible to me I will try to do it one day with a good pass of SO-50 and Fox 1A (and maybe Lilacsat if it is active). 73s, Felix De: amsat-bb-request(a)amsat.org Enviado: martes, 22 de marzo de 2016 22:34 Para: amsat-bb(a)amsat.org Asunto: AMSAT-BB Digest, Vol 11, Issue 88 Send AMSAT-BB mailing list submissions to amsat-bb(a)amsat.org To subscribe or unsubscribe via the World Wide Web, visit http://www.amsat.org/mailman/listinfo/amsat-bb or, via email, send a message with subject or body 'help' to amsat-bb-request(a)amsat.org You can reach the person managing the list at amsat-bb-owner(a)amsat.org When replying, please edit your Subject line so it is more specific than "Re: Contents of AMSAT-BB digest..."

Message-ID: <002101d182f8$8b020240$a10606c0$@net> Content-Type: text/plain; charset="us-ascii" Hello all, I have a question for those of you much more experienced than I. It relates to a satellite antenna installation I am working to accomplish this Spring. I have two cross polarity yagis, one for 145 and the other for 435. Each of these antennas has two separate feeds for the H and V polarities. The two meter antenna has two feeds, both at about 14 inches from the end of the antenna boom. Jumpers from the connectors will be secured to the very end of the boom and trail off to main feed line connectors below the AZ rotor. The mount point of this boom is 5' 2" from the end of the boom with the driven element. The 70CM yagi is an end mount but the two connection points are offset from each other. One is 17 inches from the back end of the boom and the other is 24. Coax jumpers will again be attached to the boom and will trail off to connections below my AZ rotor. I will be using two separate rotors, (A G5400 or G5500 is not in the paycheck right now), an elevation rotor with a 4'2" boom to mount the two antennas and an azimuth rotor which will have a probably 2' maximum mast from there to the EL rotor mount. All this will mount to an only half extended push-up-pole, which is ground mounted but attached to the apex of my single story house. Total height off the ground will probably be 20 feet when all is said and done. I will be running 4 runs of not that flexible 9913 up to just below the AZ rotor and from there want to attach jumpers of more flexible LMR 400 Flex to make the runs out to the antennas mentioned above. My question is for your more math savvy or just plain experienced folks, is how long should the jumpers be in total for each antenna to allow for a 360 degree rotation and 180 degree elevation shift based on the parameters I described above??? I was guessing 10 to 11 foot jumpers from antennas to the barrel connectors just below the AZ rotor but wanted to make sure that that was long enough, or if they could be shorter, say maybe 9 feet. Of course the 70 CM antenna with it's one feed point 7 inches further up the antenna would need to be that much longer I guess. I also understand that the 2 meter swing will be greater because of the more center mount rather than the end mount on the 70 cm antenna. Clear as mud??? This is new territory for me so I am wanting to make sure that all the decisions are right before I need to do things over, and over, and over to get it right. I can take some pictures if someone needs to see what I described. Email me and I will give you my cell if you would rather talk or ask questions verbally. Thank you to the group in advance for your help and thoughts.

I had an AMSAT table at the Scottsdale Amateur Radio Club's "Springfest" hamfest, held in a church parking lot yesterday (Saturday, 19 March) morning. This hamfest is one of the 3 major hamfests for the Phoenix area in the non-summer season, and the good weather helped to bring the crowds out. Lots of buyers and sellers, and lots of interest in AMSAT and amateur satellites. With the launches of AO-85 and the 9 Chinese amateur satellites in the past 6 months, many hams are taking a closer look at this part of the hobby. For some, the recent launches and projects currently in the pipeline are bringing some back to the satellites. Along with talking about satellites, many copies of AMSAT's "Getting Started with Amateur Satellites" flew off my AMSAT table. Demonstrations, whether at 6am (1300 UTC) or 11am (1800 UTC), had nice crowds. It was nice to have AO-85 available during the morning, as SO-50 was not passing by during the morning. I also had 4 other satellites that were used for demonstrations - AO-73, XW-2A, XW-2C, and XW-2F. The three XW-2 satellites were passing by in the first couple of hours, and AO-73 and AO-85 came by later in the morning. For all of these passes, I used my SDRplay SDR receiver for the downlinks, connected to an 8-inch Windows10 tablet and HDSDR software running on the tablet. As I have seen at other recent events, using an SDR receiver makes for more conversations - and not just in the context of working satellites. With all of these satellites employing a 70cm uplink and 2m downlink, I didn't have to worry so much about the sunlight making the tablet's LCD panel unreadable. Once I set my downlink frequency on the tablet, and for AO-85 activate AFC in HDSDR to track the downlink, I only had to worry about using the wheel on a Bluetooth mouse for fine-tuning. Despite some QRM in the area of the hamfest site, northeast of a nearby airport, the SDRplay did a decent job hearing all of these downlinks. For AO-73 and AO-85, I was able to play back the RF recordings I made with HDSDR later at home, so I could upload telemetry to each satellite's telemetry server from those passes. By the way, HDSDR's recordings do a much better job picking up AO-73 telemetry than I ever saw when I used the FUNcube Dashboard to directly receive the telemetry and then upload the data to the FUNcube data warehouse server. Same thing for copying AO-85 telemetry - HDSDR's RF recordings do better for capturing the data than I saw when using the FoxTelem software to directly control my FUNcube Dongle Pro+. For those who worked WD9EWK during those demonstrations - THANK YOU! The demonstrations make a positive impression on this part of the hobby for the crowds. My mockup of the AO-85 satellite - a 4-inch cube of wood, with two whips representing the antennas coming out of two sides - also helps to reinforce that small satellites can do more than "beep" in orbit. AO-73 and AO-85, in particular, are great examples of what we can do with small satellites. I have uploaded my log to Logbook of the World from these demonstrations, and am happy to send QSL cards to anyone who would like one for QSOs during the hamfest (just e-mail me with the QSO details - no need to send me a card and self-addressed stamped envelope). Thanks again, and 73!

I have in fact found out who it is and we have had a very lengthy and productive chat. He lives in Nevada, has a motor home and has plans to take a weekend to go operate from a rare grid not terribly far from his home. He is not a new sat op, but 'grid roving' is a new aspect he is in the process figuring out. He has asked for my help on working out a few details as to gear, logging, etc. I am only too happy to assist. I will let him announce his own plans, as that is only polite, but I will say that if everything goes as planned, our schedules will not conflict. He should be operating the weekend BEFORE I arrive in Nevada, with him wrapping up the same day I cross the state line. =^) Hopefully between the two of us, we can work everyone that needs that grid (DM19). And hey, if he works everyone who presently needs it, I already have another spot I can go. =^D My only regret may be that I won't be home to work him myself... but I'm really glad he is going! Also, I will be operating with my portable gear as much as possible during April, in order to get well acquainted with my new gear and work out any bugs. If you hear me on, feel free to give me a holler. I might even work from a few nearby grids for anyone that needs them. Again, I will be posting info about my trip to a special QRZ page as well as sending out last minute updates on a special twitter account. Use the link: https://www.qrz.com/db/N4UFO/P or look up N4UFO/P on QRZ (must add the /P). The link to my twitter is there and you do not have to have a twitter account to watch it.

I was able to tune in and listen to a net and caught the callsign of the station conducting the net who was in Houston. It was not necessarily his station and/or node that was the problem, the signal could have been coming from any number of nodes across the US that might have been connected. I am having limited success communicating with the individual who's callsign I heard. I got one reply from his phone in response to a message I sent through the IRLP website. He is apparently not getting any e-mails from me directly despite being the same e-mail address. I'm trying to confirm what reflector & channel(?) he was connected to and then see if there is any way to research with IRLP to find out what other nodes may have been connected at the time. You know, detective work. Does anyone have experience with this? with IRLP? Anyone know how to research the stations on the IRLP side of things or who to contact? Has anyone there been receptive in the past regarding resolution of interference with the sats? It's all very frustrating as I don't see any central point of contact on their website and not getting any more communication from the one guy I heard in Houston doesn't help either. I made every effort to be polite and respectful in my communications (honey versus vinegar), but with some people that just equates to a license to 'blow you off'. =^) Thanks in advance for any help... prefer replies off list. 73!?

Has anyone ever made contact with an amateur satellite ground station in Bhutan? Are you aware of any amateur radio operators who have made contact from Bhutan via satellite? I would be interested in this information. Thank you, Clayton W5PFG

Re: [amsat-bb] AO-85 data mode
by Andrew Glasbrenner 23 Mar '16

Unfortunately, high speed data mode only runs for 15 minutes, then back to transponder mode. Europe and South America get the ends of Ascending and Descending passes where we enable it, but JA is just too far from a command station.

Any chance of leaving it in high-speed mode for a full orbit sometime in the future so us non-Unitedstatesians can have a crack at those decodes? :) -- J.

AO-85 data mode
by Andrew Glasbrenner 23 Mar '16

23 Mar '16

All, This morning and yesterday morning I switched AO-85 into high-speed data mode over the SE USA. This was necessary for some testing of ground station components prior to the launch of Fox-1Cliff and -1D coming up. I apologize for any interruption in doing so. I hope everyone had their telemetry program on "auto" and caught a few high speed frames! 73, Drew KO4MA AMSAT VP Operations

by John Brier 23 Mar '16

23 Mar '16

Frank's First ISS Reception - Walter Jackson Elementary https://www.youtube.com/watch?v=zxrOhKytmbU I met Frank, NF2O on Facebook. I shared my last video of the Miami Florida school ISS contact reception on the Ham Radio Operators Facebook group, of which Frank was a member. He saw the video and recognized the landfill park I filmed the video at. He commented on my video saying that, and that it was his favorite place to work satellites from. After chatting we agreed to meetup for the next ISS reception. This video is a result of that. Walter Jackson Elementary, Decatur, Alabama, direct via N8DEU The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Timothy Peake KG5BVI Contact is a go for: Fri 2016-03-18 13:53:49 UTC 69 deg Time Satellite Azm Elv Mag Range S.Azm S.Elv -------------------------------------------------------------------------- Decatur 2016-03-18 09:52:34 ISS 310.6 0.0 2.5 2385 108.1 23.3 2016-03-18 09:58:04 ISS 224.5 71.8 -0.8 428 109.1 24.4 2016-03-18 10:03:32 ISS 138.2 0.0 3.6 2371 110.0 25.5 Raleigh 2016-03-18 09:53:53 ISS 299.4 0.0 2.6 2388 115.1 29.4 2016-03-18 09:55:19 ISS 292.7 5.1 2.1 1839 115.4 29.7 2016-03-18 09:59:03 ISS 229.6 23.2 1.0 905 116.1 30.4 2016-03-18 10:02:47 ISS 166.0 5.0 3.0 1832 116.8 31.1 2016-03-18 10:04:11 ISS 159.3 0.0 3.7 2366 117.1 31.3 73, John KG4AKV in Raleigh, NC FM05

IRLP node interference to FO-29
by Kevin M 22 Mar '16

22 Mar '16

UPDATE: I got another reply from the individual who's callsign I heard... he is forwarding information to a couple folks with IRLP. Fingers crossed. If any AMSAT gurus, hear from some IRLP gurus, there you go... ball is hopefully rolling. Time for my daily walk. =^) 73,Kevin N4UFO
