KG5CCI/P 2015-04-25 EM23/EM33 Line
by Dave Swanson 25 Apr '15

25 Apr '15

Good Afternoon Everyone, The weather is nice and things are calm at home, so it's time for a quick rove! I will be operating portable from the EM23/EM33 line, just north of Texarkana, AR this afternoon on the following passes: 2015-04-25 2038Z FO29 2015-04-25 2059Z AO7 2015-04-25 2222Z FO29 (If needed) I will for sure work the first two passes, and can stick around for the last pass if someone needs these grids and misses me on the first two tries. I have scouted this spot out before, but never operated from EM23 on Satellites, so I'm hoping it should be a new one for at least a few of you. I'll be on Twitter @KG5CCI posting pictures of the op as I go. Hope to catch you on the birds! 73, Dave, KG5CCI

FL11 is back on the air (SO-50) ... and bad apple... (UV-5R)
by Pavel Milanes Costa 25 Apr '15

25 Apr '15

Hi to all from CO7WT, Pavel After a long hiatus I resume my activity on Satellites from FL11 (just FM here, so SO-50 Only) I have tested yesterday and today's night my setup here: Antenna: Homebrew Cross boom yagis for 2m/70cm Radio: Baofeng UV-5R *(Half Duplex)* Recording dev: my cell phone My log shows from this two days: 2015 April 24 --------------- 0159 W5CBF EM21 (Saludos Hector!!!) 0201 KA4H FM17 0202 N8RO EM00 0203 W1PA FN44 0204 WI9I EM59 2015 April 25 --------------- 0225 WI9I EM59 0226 KE8AKW EN80 0227 KG5CCI EM34 0228 KE8AKW EN80 I wrote the times approximately by looking the start of the pass and the recording time, for humans minor time differences are ok, but I wonder if LoTW can cope with that. QSL is via my manager (N2CQ) if you want paper QSL or LOTW on the following hours after the QSO. I'm being getting used to the calls and sounds, sorry to the OMs that insist on me to say his calls correctly (KE8AKW ;-) ) keep in mind that English is a second language to me, I always have a recording for correction of that "beginner's mistakes" Operations is as time permits, mostly on night passes on week days or full time on weekends; sure I can take schedules too. To the amsat.org OM's: put this info on the new "activity" page if you like so, I think FL11 will be a new grid to many of us. I have to make yet some fix on the yagui handle (comfort) and some other practical fix on the diplexer/cables, but that's are minor issues. Now lest talk about a little china apple, sorry, radio. About the baofeng UV-5R: I get a bad apple from the store... or it's not? Maybe someone of you remember a post of mine a time ago about NOT going to the UV-5R for RX on full-duplex... About a week ago I scheduled a test with a technician with certified test equipments (IFR 1200 I think it was...), we make some tests this week, short story: My baofeng has 10uV sensitivity on 2m (aprox -86dbm aka deaf) and 0.1 uV on 70cm (aprox -123dBm aka very good) Further tests shows that when you are on RX in 70cm any carrier on 2m above 50uV (aprox -73dBm give or take), the sensitivity on 70m begin to suffer, that why I can't use this radio for full duplex with other radio as TX on 2m, even with 1W of power. For reference purposes my Baofeng UV-5R has Firmware N5R-20 dated 140525N My solution was a homebrew diplexer, mounted on the antenna and working only *half duplex* Not an ideal setup but most of the time I get strong signals here and QSOs prove that it's working as expected. 73 from Pavel in FL11ai (Camagüey Cuba) CU on the birds. -- M.Sc.

Re: [amsat-bb] Update: ARISS Contact today at 16:40 UTC
by AJ9N＠aol.com 24 Apr '15

24 Apr '15

As part of my zillion other duties as an ARISS mentor, I post ARISS announcements to the SAREX-BB. Oftentimes Dave AA4KN (another ARISS mentor) will post an announcement for each specific school a few days before the actual contact that has a little more information about the school itself to the AMSAT-BB and SAREX-BB. We do not have an ARISS only type of list. As part of my announcements I do indicate where one can find the complete schedule. You can go to: http://www.amsat.org/amsat/ariss/news/arissnews.rtf This one has all of the schools that are presently in our schedule queue. http://www.ariss.org/upcoming-contacts.html This one has the schools that have actually received their contact date and time. http://www.issfanclub.com/ The ISS fan club always is user updated regularily. As always, ARISS suggests that you start listening about 10 minutes before the indicated time. 73, Charlie Sufana AJ9N One of the ARISS mentors In a message dated 4/24/2015 3:11:35 P.M.

ARISS Contact (4/24)
by Ronny Risinger 24 Apr '15

24 Apr '15

Thanks for sharing the ARISS contact info. I set up our school's computer software (SatPC32) to track the ISS (from our QTH in Austin, TX). Because the pass occurred during my Government class, I explained the ARISS program and how it brings goodwill toward NASA and ISS. I then showed them the Italian astronaut's photo, and explained that she would be speaking with a school in Maryland. With that setup, we walked to the "Radio Room." As we counted down the seconds to AOS in MD, we heard nothing. After about five seconds, I turned down the squelch and Bingo! We listened to the downlink for about five minutes before returning to class. The students (Seniors) were genuinely impressed. FYI: The satellite tracking station we used to monitor this pass will be pictured in QST's June issue.

Re: [amsat-bb] Has anyone heard the 9600 baud signals from Spinsat?
by Armando Mercado 24 Apr '15

Hi, I've listened for Spinsat on 437.230 several times with no results. There have been no reception reports from Spinsat to the best of my knowledge. It is still near the ISS. Latest keps can be found at: http://www.celestrak.com/cgi-bin/TLE.pl?CATNR=40314 73, Armando N8IGJ
