Fwd: [PVRC] W1AW/4 Virginia Ops Needed!
by Paul Stoetzer 12 Mar '14

12 Mar '14

Looks like K4ZW is looking for a satellite operator or two or more for W1AW/4 in Virginia. Worst case, I'll cross the Potomac and operate a few passes, but I know there are plenty of you out there! 73, Paul Stoetzer, N8HM Washington, DC ---------- Forwarded message ---------- From: Ken Claerbout <k4zw(a)verizon.net> Date: Mon, Mar 10, 2014 at 9:25 PM Subject: [PVRC] W1AW/4 Virginia Ops Needed! To: pvrc(a)mailman.qth.net Hi Gang - just a little less than a month before the ARRL Centennial QSO Party comes to the Commonwealth in the form of W1AW/4. We still have plenty of operating slots available. Given all of the top notch PVRC operators and contest stations in Virginia, we should have little problem putting on a big time effort. Please take a few minutes to go to http://www.nr4m.com/ARRL-Centennial-QSO-Party and check out the information we have posted. At the bottom of the page is a spreadsheet with the schedule, showing available slots. This is a unique opportunity. Others that have gone before us have reported high levels of activity with some big QSO totals for their week. I'm hoping we can tap this groups competitive spirit and push the bar even higher. Let's give our neighbors something to shoot for! I know it might be difficult to plan in advance but we need to start nailing things down. So if you can commit, please do so. If your plans change, we'll work with you. 73 Ken K4ZW ______________________________________________________________ PVRC mailing list Home: http://mailman.qth.net/mailman/listinfo/pvrc 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

Re: lotw

i think band is 2m, 70cm, 13cm (which is for the rx frequency) mode fm or ssb satname is so50, ao51, ao27 etc prop mode is sat anything else have to be changed (i have only logged the rx frequency, not the tx frequency) 73...bruce Sorry but "BAND" is the transmit band and "RX_BAND" is receive band. The Transmit band is what is relevant to matching. I am afraid you will need to change the BAND to the uplink band, or the QSOs will not match. A Sat QSO is: CALL, QSO_DATE, TIME_ON, BAND, MODE, PROP_MODE, SAT_NAME Maybe this will help: http://www.arrl.org/files/file/LoTW%20Instructions/N5JB.pdf Just a note, my logging program (WINLOG32) does not handle satellite QSOs very well. I have resorted to using TQSL to create sat logs. At first I had all my sat QSOs in one file... then a bright idea hit me. I keep a separate log file for each satellite/mode, so after a pass, when I go to enter new QSOs, I just enter CALL, DATE and TIME... and click next. The rest is always the same. Much quicker than having to constantly change the band and sat name. Anyway, you can also load an existing ADIF file into TQSL and use the pull down menus to edit fields. You can step through QSOs one at a time. Don't know if that would be any easier for you or not. 73 es GL! Kevin, N4UFO (ex-AC5DK)

lotw
by Bruce 12 Mar '14

12 Mar '14

i have decided to try lotw again after using it in 2003 and having a miserable time with it. i need to find someone that i have had a satellite qso with that has uploaded their log so i can change that record or two and then see if i get a match before i try to modify each of my 6500 satellite contacts. it is going to take me a long time to go through and change each record to match the lotw criteria and will take me a long long time. want to make sure it is correct before i start logging new contacts. i have never found much use in lotw as all my contacts are confirmed by qsl card. not sure why i want to go through the exercise but what the heck. i think band is 2m, 70cm, 13cm (which is for the rx frequency) mode fm or ssb satname is so50, ao51, ao27 etc prop mode is sat anything else have to be changed (i have only logged the rx frequency, not the tx frequency) 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards ARRL Awards Manager (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

Re: Two hundred 437 MHz satallites launch March 16 + WebSDR
by Howie DeFelice 11 Mar '14

"Keep in mind that the downlink is not effected by usa rules...." This may be true if the owner of the satellite is not licensed in the USA or it is operating on some service other than the Amateur Radio Service. ITU recommends policy, it doesn't make or enforce law as I understand it. Before this gets too much further into the weeds, the purpose of my original post was to bring awareness that satcom is regulated by cooperative national authorities and is not the "wild west" of radio spectrum. This is true whether it is an amateur of commercial satellite regardless of size. Just because you can build it and get it launched does not mean it is legal. We all have a responsibility to be vigilant. I don't think too many people would intentionally put up a satellite in violation of the rule of law, but it is a complex issue. It never hurts to ask a question. - Howie AB2S

EM90,80,70, maybe EL79, EL89
by Andrew Glasbrenner 11 Mar '14

11 Mar '14

I'll be in EM90 tonight and tomorrow, then travel through EM80 to EM70 Wednesday afternoon to evening. I may pass back through EL79 Thursday afternoon, then EM80 and EL89 to home. If you need any of these grids, drop me an email. I only have my 817s and arrow, but should be fine on any of the sats as long as no one is hammering the transponder. 73, Drew KO4MA Sent from my iPhone

Is CDMA an authorized emission type for the Amateur service? What is the chipping rate/bandwidth of these? Don't the PRN sequences need to be made public so as not to be classified as "encryption" ? Detailed specs on the Sprites is in short supply. Has anyone done a link budget, seems like allot of spreading gain is required to hear 10mW form a 300km orbit which translates into allot of bandwidth in a part of the band usually reserved for narrow band modes. The lack of transparency on many of these projects that use the amateur bands seems to run against the spirit of amateur radio in my opinion. Howie AB2S
