Re: [amsat-bb] Circular Polarization vs. Preamps

Hi Fred There is nothing better than circular polarization for fixed antenna systems. I have worked many satellites with fixed antenna in elevation (35 degrees) but only I could do well with the SSB. I can only work with FMs when installing circular polarization antennas with the possibility of changing their sense (LHCP / RHCP) and installing low noise preamplifiers (AR2) 73 to all Mike LU3EMB Obtener Outlook para Android<https://aka.ms/ghei36> On Sat, Nov 26, 2016 at 3:36 AM -0300, "amsat-bb-request(a)amsat.org" <amsat-bb-request(a)amsat.org<mailto:amsat-bb-request@amsat.org>> wrote: Send AMSAT-BB mailing list submissions to amsat-bb(a)amsat.org To subscribe or unsubscribe via the World Wide Web, visit http://www.amsat.org/mailman/listinfo/amsat-bb or, via email, send a message with subject or body 'help' to amsat-bb-request(a)amsat.org You can reach the person managing the list at amsat-bb-owner(a)amsat.org When replying, please edit your Subject line so it is more specific than "Re: Contents of AMSAT-BB digest..."

See my QRZ page for picture of how I have it setup outside when I operate. I am trying to put together a more permanent antenna system within my budget. I have been rather surprised how much fade is apparent in some of the birds which responds usually to some degree by twisting the axis of the Arrow antenna. So, my question is as follows: Would you rather have: A) The ability to switch polarization, presumably from RHCP to LHCP (or maybe even vertical to horizontal)? Unfortunately my research shows to date that this option is still rather expensive. Any suggestions on how to achieve this on a modest budget would be appreciated. OR B) A reasonable preamp on both 2 meters and 70 cm? (I have never worked with a preamp yet-though I have ordered the "Original Broadband Satellite RX Preamp? from the AMSAT store and plan on using that and switching it manually depending on what bird I am using into the receive side). For information, I will have about 70 feet of feedline. Assuming that one cannot have both. As usual, I really appreciate your time and input.

This is where the grid activations are really going to be weather dependent. First of all, I'm afraid I have to sacrifice FN17. It's in the wrong direction and the distances are too great. Tomorrow will be all about FN09, FN18 and FN19. To be efficient, I will try to operate from grid boundaries, specifically FN18/FN19 and then FN09/FN19 a little later. Hopefully, I can park on the side of the highway without getting in the way. If you look at it on a map, the highway (Hwy 109 north from FN18at) connects civilization with...well, very very little! Traffic should be very light. I have a long drive to my next hotel tomorrow evening, so I am finishing up with the AO-7's pass at 2021. I hope I have this right...AO-7 will be in Mode B tomorrow? If not, there won't be much to do. SO-50 isn't positioned well. The only opportunity we have tomorrow is at 1305. I was hoping to do better for the FM-only ops.

When AMSAT announced their 2016 symposium would be on a ship, you immediately tried to sink it. You were shot down by numerous, well respected individuals who have something you haven't got -- humility. When's the last time you attended a symposium? Ummm, never? http://www.amsat.org/pipermail/amsat-bb/2016-January/056856.html http://www.amsat.org/pipermail/amsat-bb/2016-January/056858.htmlhttp://www.… You have no idea what a symposium costs AMSAT. The meeting space, tea, coffee, etc. didn't cost AMSAT a dime on the cruise ship. Just because you don't like W5PFG, don't take it out on AMSAT. Your idiotic posts clearly demonstrate you can't tell the difference between a general meeting slide deck and the symposium event. You just have a bone to pick because someone out-did you, again. I like how you decided to bring the conversation to your personal domain (Yahoo Work-Scat) rather than publicly discuss on AMSAT's message forum, the AMSAT-BB. Petty and weak! While we are at it, why do you even care about AMSAT? A few months ago, you threatened them with legal action if they didn't "reign in" one of their most dedicated volunteers. That man, WD9EWK, happens to be one of the most generous and outspoken educators in the satellite community. You are not a team player and frankly I don't see why AMSAT didn't strip you of your "Area Coordinator" title sooner! Nobody cares about the "kudos" and "thank you" emails you supposedly get via email. Most of the time, you are talking to yourself on the self-promoting forum threads you scatter across the web. Intelligent people pick up on your silly auctions as a PR trick to get more website hits. Today you're promoting barbed wire antennas again on another forum. How silly? Barbed wire is not an effective material for constructing antennas. Because one guy did it as a novelty, you act like it should work for everyone in every situation. Face it, your advice sucks. Your frequency chart (which was wrong for a long time, BTW) is basically your one trick pony. Any videos of you working a satellite on YouTube demonstrate your novice skill level. I'm thankful this season that you are not a professional educator in any school system. _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

Scott, thanks for sharing. You can know if the satellite is sunlit or not in real time during pass. Try http://amsat.org.ar/pass.htm clicking HO-68. If it is sunlit a little Sun Icon will show top right close to the name. If it is dark then the Sun Icon will not show. This takes into account height of satellite and if sees Sun. 73, lu7abf, Pedro On Sat, Nov 26, 2016 at 12:54 AM, Scott wrote: > On the 00:47 UTC pass over the U.S., I copied 3 good CW transmissions, but > they were not complete telemetry sessions.

Xiwang-1 HO-68 report
by Jean-Pierre Godet 26 Nov '16

Hi my friends, With illuminated solar panels, the signal was better this morning than yesterday evening on this pass over western Europe at about 0830 UTC (orbit number 33392) and I was able to copy some whole frames. 08:28:20 UTC, full telemetry frame then silence ; 08:30:50 UTC, only the letter B then silence ; 08:35:35 UTC, two full telemetry frames and the begining of the next one (after that, silence). The record of these two and a half frames is here: http://f5yg.pagesperso-orange.fr/incoming/HOPE-1_orb33392_26nov2016.mp3 and the content here: BJ1SA XW XW AAA TTT AVN VNE ETT TTT TTT TTT TTT TTT TTT TTT TTT XW XW BJ1SA XW XW AAA TTT AVN A6E ETT TTT TTT TTT TTT TTT TTT TTT TTT XW XW BJ1SA XW XW AAA TTT AVN VNE ETT T channel 1: AAA ==> 111 ==> PA number 2 is the one working ; channel 2: TTT ==> 000 ==> beacon mode only ; channel 3: AVN ==> 139 ==> TX temperature + 39 deg.

AMSAT Symposium
by Clint Bradford 26 Nov '16

26 Nov '16

I sure hope you - the moderator of my posts here - allow this little rebuttal to the post from “Pablo” that you allowed earlier today. My bottom line remains: What can we all do to make AMSAT-NA survive. ——————————————————————————— Well - good evening to you, too, Pablo. >> When's the last time you attended a symposium? Ummm, never? I just love it when truly ignorant statements are made - as if the writer knew anything about what they are talking about. I attended an AMSAT Symposium when it was in San Jose, CA. I also accumulated one of the finest assemblage of raffle prizes AMSAT-NA has ever seen when I was prize coordinator for their symposium a couple years ago. Got a plaque signed by the AMSAT prez for that effort. I know exactly what a cruise costs. I know precisely what it costs to put on events. I orchestrated a city-wide event for Riverside, CA (population 300K) that had about 7,000 attendees. From parking to logistics to communications to placing a repeater atop a local hill to working with each and every vendor - I know what it takes. I also worked with the publicity director for a large regional newspaper. I have also been involved with several 501(c)(3) organizations with their fundraising and grant writing projects. I also orchestrated an ARISS contact for my City of Jurupa Valley - earning FRONT PAGE WITH COLOR PHOTOS coverage in California’s sixth-largest daily newspaper. Along with NPR interviews, coverage by other video outlets, video highlighted on the Bob Heil / Gordon West Ham Nation mediacast - I did it all for our students. So you have no idea who I am or what I have done. Yet you spout your venom ... A group in financial problems holding an annual event on a cruise. If you do not see how horrible that looks - from a public relations and marketing aspect - then you are either naive or just plain ignorant. I acknowledged on the AMSAT-BB list that you made good points. You are welcome. How I am “self-promoting” myself - actually “promoting working the birds” has proven effective. I am approached monthly by conventions, groups, municipalities, clubs - to find out more about working the FM birds. In that aspect - “spending the word” - I am tremendously successful. >> … Barbed wire is not an effective material for constructing antennas … Tell that to the Boy Scouts who used that barbed wire antenna to speak to an astronaut who was aboard the ISS at the time. YOU are just one of a handful that, apparently, just don’t get it. Working a couple of the FM birds is not something one needs to put a lot of money in to. Is using barbed wire the same as spending $500+ and using an M2 2MCP28? Nope. DOES IT WORK FOR THIS? ABSOLUTELY. >> … you act like it should work for everyone in every situation … Bovine excrement. Can one make an effective 2M/440 antenna and work a bird or three? Absolutely. >> … I'm thankful this season that you are not a professional educator in any school system … Sorry to disappoint you - but I still volunteer for NASA and am earned my registered ARRL instructor position. Clint Bradford K6LCS PS By the way, I don’t see any posts from you suggesting tactics to “save” AMSAT-NA from its current financial problems. At least a few of us are … But not you …

On orbit 33389 over Buenos Aires, on Nov-26 at 02:10z on 435.790 MHz strong copy of HO-68 CW Beacon. Just at that time, when HO-68 went dark, CW reception stopped. Seems Sun is needed to operate, congrats to recovery team. 73, LU7ABF, Pedro

Circular Polarization vs. Preamps
by Fred Castello 26 Nov '16

26 Nov '16

Folks, I have now finally become active again on some of the satellites with a handheld Arrow and my bulky but beloved Kenwood TS-790A. See my QRZ page for picture of how I have it setup outside when I operate. I am trying to put together a more permanent antenna system within my budget. I have been rather surprised how much fade is apparent in some of the birds which responds usually to some degree by twisting the axis of the Arrow antenna. So, my question is as follows: Would you rather have: A) The ability to switch polarization, presumably from RHCP to LHCP (or maybe even vertical to horizontal)? Unfortunately my research shows to date that this option is still rather expensive. Any suggestions on how to achieve this on a modest budget would be appreciated. OR B) A reasonable preamp on both 2 meters and 70 cm? (I have never worked with a preamp yet-though I have ordered the "Original Broadband Satellite RX Preamp” from the AMSAT store and plan on using that and switching it manually depending on what bird I am using into the receive side). For information, I will have about 70 feet of feedline. Assuming that one cannot have both. As usual, I really appreciate your time and input. Best, Fred-KF4FC Fishersville, VA

AMSAT Symposium
by pablomiel70＠yahoo.com 26 Nov '16

Clint Bragford K6LCS, Your posts amount to an epic fail. When AMSAT announced their 2016 symposium would be on a ship, you immediately tried to sink it. You were shot down by numerous, well respected individuals who have something you haven't got -- humility. When's the last time you attended a symposium? Ummm, never? http://www.amsat.org/pipermail/amsat-bb/2016-January/056856.html http://www.amsat.org/pipermail/amsat-bb/2016-January/056858.htmlhttp://www.… You have no idea what a symposium costs AMSAT. The meeting space, tea, coffee, etc. didn't cost AMSAT a dime on the cruise ship. Just because you don't like W5PFG, don't take it out on AMSAT. Your idiotic posts clearly demonstrate you can't tell the difference between a general meeting slide deck and the symposium event. You just have a bone to pick because someone out-did you, again. I like how you decided to bring the conversation to your personal domain (Yahoo Work-Scat) rather than publicly discuss on AMSAT's message forum, the AMSAT-BB. Petty and weak! While we are at it, why do you even care about AMSAT? A few months ago, you threatened them with legal action if they didn't "reign in" one of their most dedicated volunteers. That man, WD9EWK, happens to be one of the most generous and outspoken educators in the satellite community. You are not a team player and frankly I don't see why AMSAT didn't strip you of your "Area Coordinator" title sooner! Nobody cares about the "kudos" and "thank you" emails you supposedly get via email. Most of the time, you are talking to yourself on the self-promoting forum threads you scatter across the web. Intelligent people pick up on your silly auctions as a PR trick to get more website hits. Today you're promoting barbed wire antennas again on another forum. How silly? Barbed wire is not an effective material for constructing antennas. Because one guy did it as a novelty, you act like it should work for everyone in every situation. Face it, your advice sucks. Your frequency chart (which was wrong for a long time, BTW) is basically your one trick pony. Any videos of you working a satellite on YouTube demonstrate your novice skill level. I'm thankful this season that you are not a professional educator in any school system.
