KB2M BACK OTA
by jeff griffin 06 Dec '14

06 Dec '14

Yesterday I got my new downsized sat station up and running here in Turnersville,NJ FM29ks, on 2m and 70cm. Only real issue was the LVB tracker's screen went blank for no apparent reason. I had to open it up and do a reset and then re calibrate. All appears to be working ok now. Made several contacts on FO29, and AO73 while working on getting the LVB pointing the antennas in the right direction. It's good to be back on the birds! 73 Jeff kb2m

I am looking for someone who can be an "Elmer" for me on operating a Yaesu FT-847 in satellite mode. I have been having some limited success but would love to talk to someone who is currently using an FT-847 in the manual mode. I do not have my 847 connected to SATPC-32 yet. Please contact me off the BB at wa7eth(a)frontier.com. Thanks..73'..Ed WA7ETH

NOAA Weather Satellite receiver
by Rupesh Lad 05 Dec '14

05 Dec '14

Hello all; I am an undergraduate Engineering student and a SWL. I have tracked many Amateur satellites from COEP Ground station, VU2COE. I want to Home brew a NOAA satellite image receiver as my academic project. I will be using WXtoImg to decode the image transmitted by NOAA satellite on APT frequency. So the task for me is to get the audio frequency output. Literature says that NOAA satellites transmit a signal of 40 kHz bandwidth. I have also observed the spectrum on Spectrum analyzer using my antenna. Want to know whether this is only RF bandwidth? and if it is so, then what is IF bandwidth of such signals? Can anyone help us in designing the receiver? -- Regards, Rupesh Lad Secretary, COEP HAM Club +91 82376 79081

W1AW/9 -IL update
by Grant Zehr 05 Dec '14

05 Dec '14

W1AW/9 operations - update W1AW/9 satellite operations are underway with lots of contacts in the log. I am planning to continue to get W1AW/9 - IL on the air during as many satellite passes as possible through the weekend and into next week. Some notes regarding W1AW/9 satellite operations: SO-50 - I seem to have trouble hearing SO-50 well below 5-10 degrees elevation. I have made a number of contacts, but have missed a few as well. If you would like to work W1AW/9 - IL and can only operate SO-50, I would be willing to make a schedule during a late night pass, which would probably not be as congested as the usual daytime passes. Contact me at aa9lc(a)amsat.org <mailto:[email protected]> . Serious enquiries only!! FO-29 - Still the workhorse with nice signals. I usually call in SSB mode. If you prefer CW, just call me back in CW and I will switch modes. I'm good at straight key rates (15-20 wpm range). AO-73 - Remember, W1AW/9 - IL counts as another call for your 73 on 73 award. ISS packet - evening to late night passes are available now. I'll try to get on the ones that don't conflict with AO-73. AO-7 - Saturday afternoon should be good for DX from here into Europe. I plan to be on AO-7 and FO-29 looking for DX on Saturday afternoon. I will be operating from EN-50. I don't need your grid for a complete QSO, call sign and report is enough. I can switch to CW to complete a contact if necessary. Weekend schedule: W1AW/9 - IL should be active Saturday AM and afternoon, and again Sunday afternoon and evening. Thanks for all the calls! It's great fun. Grant Zehr AA9LC

UISS Modul SatGate
by Peter Kaminski 05 Dec '14

05 Dec '14

Hello APRS freaks, I have a question about the UISS APRS SatGate module. As default the server" satgate.aprsca.net" is set in the APRS settings. Very often it seems to be that my gateway aprs data is not passed to aprs.fi So my question is can I use "euro.aprs2.net" for example as an alternative or is there anything special with satgate? Are the satgate data also passed to http://www.ariss.net/?? I coul not find anything about the routing. regards Peter -- Peter Kaminski Vogt-Wells-Str. 5 22529 Hamburg Germany Phone: +49 40 41477811 Mobile: +49 172 4053333 Skype: peter.kaminski.hh Web: www.dl9dak.de

Re: [amsat-bb] VIBE table available to government agencies or programs
by Robert Bruninga 05 Dec '14

This VIBE table suitable for vibration testing of Cubesats is still available… Hate to see it go to the DRMO where the government will set it out in the rain for a few years, and loose all the components and documentation before making it available as surplus… *From:* Robert Bruninga [mailto:[email protected]] *Sent:* Thursday, October 23, 2014 10:18 AM *To:* amsat-bb(a)amsat.org *Subject:* VIBE table available to government agencies Our vibe system is available to other government activities or programs. You do the paperwork… It is only a few years old, is working fine. But we got another one – bigger. We needed one to provide a full 20G vibe on a 3U cubesat. This one can only get to 20 g on a 1U. Here is what it looks like: http://www.labworks-inc.com/general_purpose_systems/lw127_123-500D12.htm I have no idea how things get transferred, but I am certain that our comptroller will only let us transfer it inter-agency. So if you are not somehow able to get a government transfer, please don’t bother asking. And we are still waiting to see if any other department on campus wants it. This thing is big. The image on the above web page has a 19” half-rack for the amp as shown on the left, but the image of the VIBE table itself is at HALF that same scale in that image. SO it is actually twice as big, about 4’ long, 3’ high and 2’ wide and very heavy half inch steel, double the size shown. Bob, WB4aPR

AMSAT @ Superstition (Mesa AZ) hamfest on Saturday, 6 December
by Patrick STODDARD (WD9EWK/VA7EWK) 05 Dec '14

05 Dec '14

Hi! I will have an AMSAT table at the Superstition Superfest hamfest in Mesa, Arizona, this Saturday (6 December 2014). The hamfest starts at 7am/1400 UTC, and officially runs until 2pm/2100 UTC - although in the past most have packed up and left by midday/1900 UTC. More information about the hamfest is available at: http://www.superstitionsuperfest.com/ The hamfest site is in grid DM43. During the hamfest, and weather permitting, WD9EWK will be on the air for demonstrations of amateur satellite operation. If you hear WD9EWK, please call and be a part of the demonstrations. I hope to be ready to work passes between 1230 and 1300 UTC. If you work WD9EWK and would like a QSL card, please e-mail me after the hamfest with the QSO details. QSOs will also be uploaded to Logbook of the World. During the hamfest, I will post photos and updates on my @WD9EWK Twitter feed. If you do not use Twitter, my feed can be viewed using a web browser at http://twitter.com/WD9EWK 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Fwd: [Hearsat] W9YRC repeater on 484.250MHz

I thought the list might find this interesting. 73, Drew KO4MA Sent from my iPhone Begin forwarded message: > From: "P.J.

At the top it was on the Russian apogee and low elevation from Chicago. If anyone else can check this satellite that would be handy, I have significant DTV QRM all over 478MHz so its a little painful to RX etc. The W9YRC seems to TX on 442.875MHz so the satellite has a pretty good receiver - still not bad DX from Chicago to UK via a 40,000Km high satellite! > > regards, > > Paul. > -------------------------------------------------------------------- > Contributor to: www.uhf-satcom.com - http://twitter.com/UHF_Satcom > > UHF Satcom Yahoo Group: http://groups.yahoo.com/group/UHF-Satcom/ > > IRC - pjm @ #hearsat on irc.starchat.net > > Correspondents should note that all communications to this address > are automatically logged, monitored and/or recorded for lawful > or other purposes. > > Telephone: 0044 (0)845 193 0050 Skype: M0EYT_Paul > -------------------------------------------------------------------- > ______________________________________________________________ > HearSat mailing list > Home: http://mailman.qth.net/mailman/listinfo/hearsat > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html
