ARISS SSTV Archive Update Needed Before Diploma App Can be Submitted
by John Brier 29 Jul '15

29 Jul '15

First of all, Thank you to all involved with ARISS and especially these SSTV events and the diploma process. I know you are all volunteers and just doing this in your free time. Second, I should have submitted my images earlier, but I ended up only submitting them on the 28th around 5:00 UTC I downloaded the latest image on the archive, from KE8AKW and the timestamp on the file is from the 25th. The application requires we send links to our images as they appear on the archive, and the deadline is the end of the month, so I am worried it won't be updated in time for me to submit my application. Any insight someone can offer on this? Thank you. John Brier, KG4AKV

G-5500 Controller Question
by Tony 29 Jul '15

29 Jul '15

All: I have an old Yaesu G-500A elevation rotator and a refurbished Yaesu G-1000 DXA azimuth rotator that I'd like to use with a G-5500 controller. I suspect the controller will work with the G-500A right out of the box, but I don't know about the G-1000 DXA. Any ideas? Tony

g5400 AZ/EL control
by Michael J. Wolthuis 28 Jul '15

28 Jul '15

I have been out of the SAT new station construction for a while. I use a Uni_Trac on my station at home and have been for over 6 years. Now I am building a station for someone else. I need to control a g5400b. Is the LVB SatTracker from the Amsat store the way to go? Then use Sat32 to control the radio and the LVB? Any other ideas would be good, but this is for beginners and needs to be simple to put together and use. So, prefer not to use the Adrino solution. Thanks, Mike kb8zgl

Hi folks, I now have the satpc32 again controlling my TS790. I purchased a new usb/serial cable from the U.K. downloaded the drivers and it works fine. This cable is almost half the price of the other one which stopped working. It only cost 16., Tried it on Fo-29 and it does the job hi hi. 73 de Scott VE6ITV

duplexer used as a filter
by kb2m＠arrl.net 28 Jul '15

28 Jul '15

I'm trying to setup a remote sat station and need help with a desence filter. I was using a Diamond MX72-n and was experiencing water intrusion. I then checked the archives and consulted the group and went to the recommended Comet CF-416. Guess what, I'm still getting water into the duplexer. I thought that it was more suited to outdoor service on the recommendation of the group. So, before I take apart one of the duplexers to attempt to waterproof, does anyone know of a duplexer that is designed for outdoor use on the tower? I really don't have the room for a 12 foot + crossboom, so I need to resolve the desence with the duplexer. Any suggestions from someone who has solved this? 73 Jeff kb2m

> Resist any temptation to seal up every crack and crevice of the diplexer. > be sure to leave a weep hole or a small gap perhaps where your cables come in through the bottom so moisture can escape. Cannot agree with the above enough... You NEVER want to try and seal it up completely; mostly because you can't. (the block of epoxy being the exception) Warm day, heat beating down on it, cool rain comes, case temperature drops quickly, air inside will condense and suck a hole in your weather seal. Now you have moist air trapped inside... no weep holes. It's the same reason you never seal both ends of hollow feedline. Are you thinking of using preamps? Then I want to suggest you try TWO diplexers... one on each feedline before the preamps. The 'unused port' on each can be capped with a simple antenna connector and a 50 ohm 1/4 watt resistor across it. Now, need room for all that? How about a tactical gear case... I've found the black cases from MCM electronics (~$25) and antenna brackets at the hardware store (~$5): http://kb5wia.blogspot.com/2011/01/satellite-antennas-again.html http://n4ufosat.blogspot.com/2014/11/finally-got-nice-day-without-too-much.… It's just a suggestion... your mileage may vary, batteries not included, attempt at your own risk. =^) 73, Kevin N4UFO

A responding station sends "W3ADO says QSL number X, my number is Y" Finishing it off with "WB4APR says QSL number Y, my number is X. Another station joins in "W4XYZ says QSL number X, my number is Z and the reply could be "WB4APR says QSL Number Z, my number is X... WB4APR made two valid contacts with XYZ and ADO. In otherwords is that required for an exchange? The number for "My number is *." is assigned sequencially for the pass, so that it is unique.

Re: [amsat-bb] duplexer used as a filter

I recommend taking some lessons from other gear that’s packaged for outdoor use. Like many outdoor preamps. Have a look at picture of these and you’ll see what I am getting at. Moisture comes from 2 places. From precipitation and from the air (condensation). I’ve use the following with great success. First the precipitation. Cover it like a “hat”. I use a piece of wide PVC or drainage pipe, though a plastic project box will do as well. I seal the top with a cap and leave the bottom open. All cables and connectors must come from the bottom for zero chance of water tricking in through a cable hole on the top or side or through the connectors. Also seal the connectors using some of the new vinyl coax wrap (love this stuff), electrical tape, or coax seal (though the latter can be a bear to cleanly remove later). What you're basically doing is affixing a “bucket” over the top of your diplexer. Now for condensation. Resist any temptation to seal up every crack and crevice of the diplexer. As long as there is any air inside, you will eventually get condensation due to temp and humidity changes. And it needs a way to get out when that happens. If you cover the bottom of your PVC pipe be sure to leave a weep hole or a small gap perhaps where your cables come in through the bottom so moisture can escape. The only perfect way around the condensation is to have no air at all inside the diplexer housing. Some companies use this approach for outdoor matchboxes and baluns where the whole thing is embedded in a block of epoxy. But before you try taking yours apart and using filler, epoxy, or silicone sealer to fill it up, let me tell you I’ve tried it and my diplexer just didn’t work well afterwards. I suffered added losses and and increased SWR. Perhaps gear just has to be designed for that from the ground up. Hope that helps.

Another possibility and one that I also use is the LabJack U12/Piggyback combination (I also have the LVB). The Piggyback you will need to build since Nova no longer sells it. The plans may be found in one of the documents that you can get for SatPC32. The U12 can be found at https://labjack.com/products/u12. The Piggyback can be found at http://www.dk1tb.de/lj_piggyback.JPG. Hope this helps. 73, Charlie AJ9N One of the ARISS mentors I don't see the LVB being sold in the AMSAT store at the moment, so this might be an alternative for you.

P3E: Happy, but urging caution
by Robert McGwier 27 Jul '15

27 Jul '15

Again, I caution. Until we have a contract, this is an opportunity. The most serious we have had since we launched AO-40 but a contract must be let to Virginia Tech by the USG to update the electronics and adapt the frame and components (remove the rocket and tanks), and get ready to use the VT ground station for operations along with AMSAT. I believe we will know before the 2017 fiscal year, but AMSAT's are ready to say yes as is VT. I love both of these guys Peter and Andrew. Be grateful after I get the USG to say yes. https://www.youtube.com/watch?v=INlUCRmRhRk -- Bob McGwier Co-Founder and Technical Director, Federated Wireless, LLC Research Professor Virginia Tech Senior Member IEEE, Facebook: N4HYBob, ARS: N4HY Faculty Advisor Virginia Tech Amateur Radio Assn.

Re: [amsat-bb] QIKCOM-2 SPoken Messages (Valid Contacts - DONE!)

27 Jul '15

Frank K5HS (ex KR1ZAN) came up with an excellent suggestion. Simply add the revolving QSO number to the downlinked GRID report! Then we need only the QSL message so that both stations can QSL each others grid!... So the DTMF grid will come down now as: "Grid FM19 from WB4APR QSO number X." A reply DTMF QSL message from someone else will be "W3ADO says QSL QSO number _. Thanks for the contact". Done. And this is an elegant simple solution that fits and the CPU only has 8 bytes of program memory left! (but 12k of message memory left)...

Bob *From:* Robert Bruninga [mailto:[email protected]] *Sent:* Sunday, July 26, 2015 4:12 PM *To:* amsat bb *Cc:* Robert Bruninga *Subject:* Re: QIKCOM-2 SPoken Messages AMSAT Armchair "contact" lawyers: Continuing with the DTMF message ideas. What kind of exchange "counts" for satellite contacts? (where counting matters)? Does it really have to be CQ... QSL... and then QSL ...? For the DTMF Voice system, we could have two more messages: " CQ Satellite, my number is *" (the satellite assigns the digit *) " QSL number _, my number is *" (station enters the _ in his reply) Usage would be: A station sends a DTMF uplink message "WB4APR says CQ Satellite my number is X". A responding station sends "W3ADO says QSL number X, my number is Y" Finishing it off with "WB4APR says QSL number Y, my number is X. Another station joins in "W4XYZ says QSL number X, my number is Z and the reply could be "WB4APR says QSL Number Z, my number is X... WB4APR made two valid contacts with XYZ and ADO. In otherwords is that required for an exchange? The number for "My number is *." is assigned sequencially for the pass, so that it is unique. The QSL station always has to enter the number of the matching station to which he is responding. Just a thought. Or does anyone give a hoot about counting satellite "contacts"?

There is still some room. Remember, for the sender using DTMF the message and callsign always fits into 16 digits from the DTMF keypad. The format is: CeMMxCCCCCCpppp# Where e is an emergency flag which, along with x, must be 9 if this is a true emergency message otherwise it says "TEST ... " Where MM is the message number (00 to 99) Where x is a numeric modifier for messages with a "_" in them. Where CCCCCC is the callsign in DTMF and pppp is the key position codes for the 6 letters See http://aprs.org/qikcom-2.html Here are the new ones implemented. ------------------------ W2JV suggested: “Greetings from AMSAT.

We have already programmed all of the ARRL standard radio grams and emergency messages. But there is room for more. So think.... What kind of message would you want to send (that is not included in the existing ones) from your HT out in the wilderness. At a hamfest? or any other HAM Radio event or opportunity. Keep them simple and of the same order of length as the existing ones. The existing ones are listed here: http://nts.ema.arrl.org/node/30 But the implementation cannot include blanks for fill-in like the regular ones. But any sentence that stands alone can work. Just thought I'd open it up. Plenty of RAM and only 1 week before delivery... Serious considerations only. Thanks Bob, WB4APR

Rotor Controllers
by Bill Booth 27 Jul '15

27 Jul '15

Wanting to upgrade my ham computer from XP/P4 to something newer and faster. Have used Nova, AEA ST-1, and Yaesu G-5500 for ever. Have a nice HP quad core machine with W7, that I cannot get to work with the ST-1, says cannot initialize port. Tried a couple of other units with same results, so I suspect it has something to do with the newer parallel ports. So what am I missing ??? I would prefer to use a USB port of course, but cannot find any controllers now that are ready to go, or will work with Nova. I am trying to stay with Nova and the Yaesu G-5500 What is everyone else using these days? -- Bill Booth VE3NXK Sundridge ON, Canada 79.23.37 W x 45.46.18 N FN05ns Visit my weather WebCam at http://www.almaguin.com/wxcurrent/weather.html Organ and Tissue Donation - The Gift of Life Talk to your family.
