[amsat-bb] Satellite Antennas
Good morning to all Well my wife gave me the ok to get some new base satellite antennas. I could really only find 2 manufactures of theses antennas in North America M2 and GulfAlpha.Is there any others,and also can anyone recommend something I would like to be able to use them for the FM sats and Transponders.

[amsat-bb] Re: Fwd: 420 - 450 MHz in Jeopardy!
This is a very serious threat as the current administration and current majority folks on the FCC are bent on making us all pay for what we get free now, that being broadcast TV and two way communications. I am in the broadcast TV profession and we just went through a transition where most every station in the country had to spend maybe a Million Dollars or more each to convert to digital broadcasting and in most cases change channels due to the spectrum repack. Remember we lost the whole of the 700Mhz UHF band to broadband and homeland security users. Now the FCC is pushing a Voluntary relinquishment of an additional 120MHZ of spectrum which would mean in large markets like Dallas, there would no longer be room for all the channels currently on the air. The thing here is that the broadband providers who will take over this additional spectrum will charge you the user for some of the same content that you can now get for free via the broadcast TV spectrum. They also want your money to communicate person to person. Now for 420-450mhz. since this is pretty much right below the 470Mhz start of channel 14. It is not at all inconceivable that in the next 10 years, as the spectrum crunch gets worse, that the whole UHF TV spectrum gets lost to broadband concerns. We are next door and don't have all the resources to fight it. So fight it we must. Even if we are secondary users, we are stakeholders and need to make our voice heard.

[amsat-bb] Re: Satellite Antennas
Hi Howard, Lucky you :) Here is my personal opinion from 20 years of operations--if you cannot change polarity, don't use circular. Linear works wonderfully. M2 yagis work great no matter what polarity the bird is in...I have installed mine vertically on a metal boom. No regrets. And they are quite a bit cheaper!! My last setup purchase included three M2 yagis, and I love 'em! http://www.m2inc.com/products/uhf/70cm/44018.html http://www.m2inc.com/products/vhf/2m/2m7.html http://www.m2inc.com/products/uhf/23cm/23cm35ez.html Price those, and then compare the price to circular ones with polarity switching on the 2M AND 70cm, and you'll see one reason I went that route :) Other reasons include quality, balance on the rotors, gain, length (around 10'), durability, and simplicity, etc. Add a 2' dish on a 8' to 10' horizontal metal boom and you're good for four bands, and the standard Yaesu G5500 will do just fine with the whole mess. Don't get me wrong---circular is more of the ideal, but it gets a bit more complicated with polarity switching (not easily done remotely for example!), not to mention the expense. 73, Mark N8MH On Tue, Feb 22, 2011 at 10:06 AM, Howard Kowall hkow...@shaw.ca wrote: Good morning to all Well my wife gave me the ok to get some new base satellite antennas.

[amsat-bb] Re: Satellite Antennas
I agree with Mark 100%. I've been using my 'terrestrial' M2 antennas on the satellites for years. The GulfAlpha Easy Satellite antenna I use for Field day is also linearly polarized, and works very well. Fades? Sure I get them, but most of the time it's only for a few seconds, and while a bit annoying it's not a show stopper. 73, Jim KQ6EA On 02/22/2011 04:11 PM, Mark L.

[amsat-bb] KB5WIA/P Mini Grid-Expedition Report (CM89)
Hi Everyone, Yesterday's mini grid-expedition to grid square CM89 was a lot of fun. I live in grid CM88 (between San Francisco and Sacramento), so CM89 was only an hour north of me and easy to get to. We drove up to Colusa in the morning, and I was able to get my QRP-portable equipment (twin FT-817ND's and an Elk antenna) set up at around 11:30am local time, just before the first of six passes. Satellite SO-50 came by first at 19:44z, it was a nice easterly ascending pass and I made around 5 QSO's with good sigs. I then had time for lunch, and the next pass was AO-27 at 20:38z with good signals as well; I made 8 QSO's on that bird. At 21:24z SO-50 came around again, this time to the west, and I was able to get a few more QSO's in. Next it was time for AO-27 to come around again at 22:18z, also to the west, and I made a couple of contacts there. At 22:33z FO-29 came by on a low easterly pass, and I had a super difficult time hearing my downlink on this one! One big problem was a huge POP a few times a second, which kept resetting the AGC in both the radio and the one in my ears! I only figured out after the pass that the noise blanker (NB) on the '817 did an awesome job at removing this popping noise. Another issue was my location, next to a local casino, turned out to have a huge amount of RF noise -- guess thousands of gaming machines tends to generate some interference! All in all, I made no contacts on FO-29, but heard a number of stations coming back to me faintly ... I just didn't have enough receive sensitivity between the pops and the slot machines to pull them out. Finally at 23:14z AO-51 came by, and I was able to make around 10 nice QSO's on that bird. Yes, AO-51 was crowded, but like others have said recently, no more crowded than many days on HF. With just a bit of patience, it wasn't a problem at all to make contacts yesterday on '51, even on a mid-day easterly pass. Overall, the day went well. It was fun to work the six passes in rather quick succession (about 3.5 hours from beginning to end). The weather was beautiful (sorry Patrick, no earthquakes, power failures, or lightning strikes), and it was a nice day to be sitting in the back of the pickup truck playing with the sats! Lessons learned: 1) Remember to double-check that tracking software is set for new grid square! 2) The noise blanker on the FT-817ND works wonders. 3) Plan to choose a radio-quiet location next time! For anyone that worked me and wants QSL cards, just send me one and I'll send you one right back. I'll head back out that way in another few months in case anyone missed me. 73 de Dave KB5WIA ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: Radios in carry on luggage
Hi John, I've done this a few times with an FT-817 and HTs. Usually I keep the radio(s) in a big ziplock bag or two and pull it out for open viewing as it goes through the x-ray machine. Lay it in it's own plastic tub even, though I usually just lay it on top of the backpack. Another habit I have is putting the big pile of cables/wires into another big ziplock bag and pull it out so they can see it in the plastic tub, too. In essence, I treat like a laptop and assume it's an item of interest to them-so show it to them! They've never asked or given me grief. 73, Mark N8MH At 02:27 PM 2/22/2011 -0600, John Geiger wrote: I am planning a couple of grid expeditions that will involve commercial flights, and wonder what experiences others have had with taking radios in their carry on luggage.

[amsat-bb] Re: Satellite Antennas
Another vote for linear antennas: I use a 20 element KLM for 70CM and 14 element Hy-gain for 2 meters. Vertical polarization. Mounted on an aluminum cross-arm with two U-100 rotors. This has been up for about 12 years, worked on every bird that's been up there, and does a fine job. Total expense: $40. 73, John, K6YK On Tue, 22 Feb 2011 18:56:34 + Jim Jerzycke kq...@verizon.net writes: I agree with Mark 100%. I've been using my 'terrestrial' M2 antennas on the satellites for years. The GulfAlpha Easy Satellite antenna I use for Field day is also linearly polarized, and works very well. Fades? Sure I get them, but most of the time it's only for a few seconds, and while a bit annoying it's not a show stopper. 73, Jim KQ6EA On 02/22/2011 04:11 PM, Mark L.

M2 yagis work great no matter what polarity the bird is in...I have installed mine vertically on a metal boom. No regrets. And they are quite a bit cheaper!! My last setup purchase included three M2 yagis, and I love 'em! http://www.m2inc.com/products/uhf/70cm/44018.html http://www.m2inc.com/products/vhf/2m/2m7.html http://www.m2inc.com/products/uhf/23cm/23cm35ez.html Price those, and then compare the price to circular ones with polarity switching on the 2M AND 70cm, and you'll see one reason I went that route :) Other reasons include quality, balance on the rotors, gain, length (around 10'), durability, and simplicity, etc. Add a 2' dish on a 8' to 10' horizontal metal boom and you're good for four bands, and the standard Yaesu G5500 will do just fine with the whole mess. Don't get me wrong---circular is more of the ideal, but it gets a bit more complicated with polarity switching (not easily done remotely for example!), not to mention the expense. 73, Mark N8MH On Tue, Feb 22, 2011 at 10:06 AM, Howard Kowall hkow...@shaw.ca wrote: Good morning to all Well my wife gave me the ok to get some new base satellite antennas.

If you don't like the FM satellites, instead of complaining that we need more linear satellites (like I have seen suggested), HOW ABOUT USING THE ONES WE HAVE??

[amsat-bb] Re: Satellite OPS9328 Launched 1967?
John. Initial defense satellite communications system...The first real communications system that the US military had. YOu can look on the web and get more information...but there is an amateur radio connection. The theory of the satellite constellation was that the satellites were dispersed about every 20 or so degrees in a almost 24 hour orbit which meant that they drifted across the sky, but slowly. This allowed multiple users by folks using different satellites and if one failed another was available. They were TRW satellites and the TRW amateur radio club got permission to launch a ham sat (Oscar IV) with one batch of satellites. Had IV got into the correct orbit it too would have drifted across the sky a few degrees every day. All the satellites were launched on a Titan III (a IIIC if memory serves) which had what was called the transtage which did the final orbit insertion and then deployed the satellites...in the case of IV the transtage failed and IV and a bunch of IDSCS's birds (and another test satellite) were left in an orbit that was highly elliptical and short lived. IV kind of looked like the IDSCS. Its great satellite history...the IDSCS satellites had a 7 year kill timer ( a chemical timer) but at least 6 of the kill timers had not worked. Robert G.

[amsat-bb] Re: Considerate satellite operations behavior.
Hi John, AA5JG You missed the point my friend because many of us extensively uses the linear satellites like VO-52 ,FO-29 and OSCAR-7 By the way they are LEO satellites but the serious satellite community need and pull for almost one HEO satellite to communicate for hours with amateurs in all continents like we did before years ago using OSCAR-10 OSCAR-13 and AO10 wich performance you cannot imagine and that you probably never tested before. I suggest you to read the old AMSAT-BB messages available in the AMSAT archive beginning from the early 2000 to 2004 when AO40 was alive and well.Here is the address: http://www.amsat.org/amsat/archive/amsat-bb/index.html Many of us remember AO-10, AO-13, and AO-40 and we missed those days. In addition many of those old satellite users and microwave experimenters are now disappointed and abandoned both AMSAT and the satellite activity. No projects for HEO satellites in the future ? No brilliant prospects for the Amateur Satellite Service if AMSAT-DL will be not able to find in short time a launch opportunity for P3-E ! 73 de i8CVS Domenico - Original Message - From: John Geiger aa...@fidmail.com To: i8cvs domenico.i8...@tin.it; Amsat - BBs amsat-bb@amsat.org; Vince Fiscus, KB7ADL vlfis...@mcn.net Sent: Wednesday, February 23, 2011 2:28 AM Subject: Re: [amsat-bb] Re: Considerate satellite operations behavior.
