[amsat-bb] Mobile Computer / Radio Installations
>> ... Most cigarette lighters circuits have a 15 to 20 amp fuse on them. That ought to work fine for charging/using with your computer ... That amount of current can/will destroy sensitive electronic devices. (20A??? That's more than what an Icom IC-706MKIIG uses at 100W TX power ... ) Personally, I would never run my laptop off a vehicle's charging system while the vehicle is running. You won't find many reputable laptop manufacturers recommending this. And all power feeds to my radio gear are properly conditioned and filtered. If I needed to run my laptop for extended periods on a 12VDC system, I would use nothing less than a ... Tripp Lite PVINT375 (although this model comes with a cigarette lighter plug, that connection has to be one of the electrically most UNreliable for what we are doing - so the plug gets whacked off and the unit is wired directly) ... or Astron Pi-250W 12VDC-to-120VAC inverter made for such circumstances. Wire it in to your vehicle's 12VDC system, and simply use your existing AC power supply. Immediate benefit is the ability to power/ charge other electronic items you may have using regular AC chargers. There's no need to know the voltage/current/connectors of the laptop. The laptop's manufacturer already did all that work for you when they supplied the AC adapter. Another downfall of using the cig lighter circuit for comms: very rarely is that line filtered for noise and such. I mean, who needs that line filtered to heat up a cig lighter? More intelligent cars do have filtered/conditioned "power ports." But I do not leave anything to chance, and make sure my equipment is properly protected. Then there are folks who run their 100W HF rigs through a cig lighter plug and swear that all's well with the world ... And so it goes.

Sorry to get defensive on Al's behalf. This thread just "feels" like a re-hash of an "engineer's view vs. real world results" argument. Like when I was told here - by engineers - that it mattered how I twisted my Arrow while working the sats. "Ya gotta take polarization into account, Clint - there's a 22db difference when you turn your antenna 90 degrees - a tremendous performance hit if you don't take this into account ... " Yet in the real world of demonstrating workin' the birds, there's no such performance degradation. I have hundreds of witnesses to this fact: Capture SO-50 and AO-51 with the Arrow and operate TX and RX while twisting the antenna in different angles doesn't change the great reception and transmission quality. If you are in the market for an Arrow, I simply suggest that you use it as offered to you. You will be pleased with its 2M and 440 amateur bands performance.

Even though the demonstration came before, and not after, the presentation I gave to the club - it all worked out very well ... It's one thing to talk to folks and tell 'em that you CAN do this ...

[amsat-bb] Presentation Feedback
I gave my presentation to a club back on September 3. They'll remain nameless - it doesn't matter who they were. At times during the show, I felt like Rodney Dangerfield - it was a rough crowd. I know my timing was a little "off" due to my wife's recovering from an emergency medical problem. But we did work AO-51 from the parking lot right before the meeting ... I had my club-specific trivia questions all prepared ... the presentation SHOULD have gone well ... Well, I just chalked it up to the law o' averages. I mean, Give the presentation, say, ten times, and there'll be one group that isn't as receptive as they should be (grin). I forgot about that night - until I received the email reprinted below last night. I am almost ashamed to post this. In my mind, I thought I had somehow failed the group. This post is not to glorify me and what I am doing - I mean it to be a "keep working at spreading the gospel of AMSAT" to all of us - no matter what silly little setbacks may occur. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Hello Clint Thanks for the great AMSAT presentation at our club on 3 Sept. 09.

[amsat-bb] New Board
Didn't see much excitement about the recent election results here. But you should know we're in capable hands with the following board members in place: Barry Baines, WD4ASW Drew Glasbrenner, KO4MA Bill Ress, N6GHZ Alan Biddle, WA4SCA Tony Monteiro, AA2TX (first alternate) In my humble opinion, we're in good hands.

[amsat-bb] Demo in Long Beach - With a Difference
Everything was proceeding marvelously last night at the Associated Radio Amateurs of Long Beach (CA) meeting. A few folks showed up early as we worked the 0053 GMT pass of AO-51 from outside the meeting room. We then moved inside for my presentation. Since my wife is in finishing a month-long trip to Tibet, I left my phone "on" in buzz mode in case she called or sent text messages. In the middle of my show, my phone buzzes. I calmly sneak a look at the phone, and was pleasantly surprised to see a QSL from XE3DX David Maciel - one of the contacts we made earlier! Oh, the audience was properly impressed! THANK YOU, David!

Unless an Arrow Antenna performance report beings with, "My Motorola test equipment - certified within the last year - indicates ... [such- and-such performance characteristics] ...

And messagegroup moderators should delete such undocumented tripe. Needless to say, I haven't read much of the recent "Arrow Performance" threads. Just aren't worth my time.

[amsat-bb] Worldwide Linking
An inquiry during my EchoLink presentation last night ... "Clint, we know the orbit of a specific satellite, we know its projected footprint, and we know its expected time over that footprint. Now if we had “X” amount of ham stations, RF equipped to talk with this satellite, and these hams were also equipped to communicate via VOIP EchoLink or IRLP and enough of these stations were lined up around the world within the orbital path, we would have continuous 24 hour, 7 day a week coverage around the world with this bird. "The EchoLink or IRLP stations would all be tied together via connection to a main conference server such as *SCARS*. This would mean that anyone worldwide could access the satellite day or night by transmitting and listening to the earth station that was in the footprint at that particular time. "I would see some things needing to be understood by the users, such as timing in regards to internet latency, repeater and or link delays, and the need to understand a pause would be necessary before transmitting, etc. " I have thought of this on a much smaller scale ...

Thank you, Mexico! Thank you, Northern California and AMSAT Patrick! Thank you, Texas! (That IS three countries, isn't it ???) I was invited MONTHS ago to show off AMSAT at the Victor Valley Amateur Radio Club's JOTA at the San Bernardino County Fairgrounds. It's an hour drive each way for me ... there ARE "closer" JOTA events occurring ... But Victorville was the first to ask ... We had a GREAT time. Arrived at 1PM for lunch, set up out informal table for the scouts to visit, and then had the wonderful pass of AO-51 at 5:55PM local time. I did NOT record the pass to initiate QSL cards - but will certainly respond to ANY of the 8+ contacts we made on both the special JOTA repeater and the "normal" V/U repeater. (That's INCLUDING Patrick, who I think had one foot in New Mexico and the other in Arizona ...) Wonderful kids ... supportive parents ... Elmers from as far away as San Diego (150 miles' drive each way). Even got my wife to go with me this time, right after her month-long trip to Tibet. Ya know when you can impress your spouse, you've accomplished SOMEthing! We couldn't spend the night, as both our horse and burro(*) called us to remind us of their regular evening feeding.

[amsat-bb] Tonight's Presentation
A couple notes surrounding my AMSAT presentation in Torrance, CA this evening. 1. THANK YOU to whichever AO-51 commander flipped AO-51 to V/U today. It was scheduled to go to V/U at 00:00GMT on the 20th - which was 4:00PM on the 19th my local time. And the pass I wanted to work was just 42 minutes later. And it was ON! 2. Don't know exactly how to explain it, but the pass today at 4:42PM Pacific Standard Time didn't exhibit the "normal" silencing, then faint voices, then stronger voices. It plainly BLASTED into discernible conversations, and we we were able to work it much sooner than "normal." We were not hidden behind foothills. It was a pretty clear shot South to AOS. It really floored me - in a most positive way. It was dramatic. 3. Thanks to KI6VBY Tim for showing up for the pass. He isn't a member of the club I was speaking to. But he follows AMSAT-BB, and has cruised my sat Web site, and wanted to meet me and work the bird together. Glad he got to meet Carl Gardenias, too. Tim's no "newbie amateur" - he has built several portable HF antennas for events, and has a great, analytical mind. He's also served our country in the military, and is working on advanced degrees in college. He had to leave right after the pass today, in order to get some school study time completed. When he has time, he'll be a valuable asset to whichever club he joins. 4. Another thanks to ARRL Orange Section guru Carl Gardenias, who helped me carry my bags to/from the meeting room. "I wanted to see your show in person," Carl advised. He said he only cringed once at my humor during the presentation ... That's it for in-person presentations this year. I still have two Internet shows lined up (EchoLink) in December. And a date in January already made. Thanks for a great year, AMSAT-BB folks!

I'll wager that I have more (a) licensed amateurs and (b) unlicensed abusers of ham and commercial bands here in Southern California than you do in your immediate area. The potential for illegal use and abuse is greater here - but (knock on wood) we have very little problems. I feel your frustration ... but I believe it can be solved with a methodical education campaign. I've contacted several illegal dispatch operations personally. I am not one to simply complain to our FCC and think my job is done. I'd rather visit and explain to someone why their ops are illegal, what the potential fines are (they range from US $3,000 to US$10,000 a day, plus confiscation of all equipment), and then show them how to get legal ... sometimes even using the equipment they already own. My methodology has worked on "problems" as large as a large commercial air carrier to small, mom-and-pop dispatchers. I have solved several problems in this manner. >> ... The only cure is to make the LEO satellite receivers less sensitive and use more EIRP at the ground station.no HT's my friend ! I think you are joking. I HOPE you are joking. One of my favorite ways to get fellow amateurs interested in AMSAT and satellite operations is to show them just how easy it is to work our LEO birds - with equipment most hams already own (dual-band HT and a better antenna). LEOs have a wonderful amateur radio public relations purpose. I am not sure how your country's department of telecommunications respects amateur radio.

I thought I read we were supposed to experience degraded performance from AO-51 since last week's re-orientation of the bird.

[amsat-bb] Re: AO-51 - After the Change
>> ... I think the handheld ops have less trouble with the polarity switching because tend to compensate more quickly with a twist of the wrist ... That phenomenon is not evident now - nor has it ever been - for me on AO-51. I know the engineers say I am supposed to be increasing or decreasing my signal strength by 22 or 23db by merely twisting my Yagi 90 degrees. But I have hundreds of witnesses during dozens of demonstrations who will tell you that when the Yagi is turned 90 degrees, there's no discernible change in the signal. This is not a scientific approach to the subject, of course. Just what my aging ears can hear. I have heard fellow AMSAT members describe AO-51's "signal fading due to the satellite tumbling in space," too. I am not using elaborate equipment, but have no idea what they are talking about. Just my firsthand observations. Guess I could be wrong ... we are a little different - I am told - out hre on the West Coast of the US. Clint Bradford, K6LCS ___ Sent via amsat...@amsat.org.

Art - What you wrote (and correct me if I misinterpreted) is that me - and others with mere handheld Yagi antennas - are achieving better results on the FM birds than those with more sophisticated linear antennas. Clint On Dec 6, 2009, at 10:31 PM, Art McBride wrote: Clint, Rotating a linear polarized Yagi in a circularly polarized field should result in less than a few dB of change, no change if the circular antenna is perfectly circularly polarized. When using a linear antenna ground effects including reflections will cause a larger change. Using circular on both ends will result in less fading from the ground effects and no change in signal for antenna rotation on the S/C side providing the S/C antenna has a good pointing angle. Losses of 22 +dB are reserved for cross polarization of antennas H-V and LH to RH. ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Portable Power for USB Devices
UPDATE 12/13/09: I have run the ZAGG spark portable power pack through a couple charge cycles. It is impressive. I am working on a deal where if you purchase one, $10 will be sent to AMSAT.

I will be creating a Web page with detailed information. - Clint Bradford, K6LCS - - - - - - - - - - - - - - - - - - - - - - - - - - Ever wanted more battery life from your iPod / PDA / cell phone or other device that charges via USB? Of course we have. The company name, ZAGG, might not ring a bell with you. But more of you have heard of the InvisibleSHIELD line they market - IMHO the best of the screen protectors for our PDA and cellphone screens. Well, ZAGG just introduced what appears to be the best of the "portable USB device power packs" available. Although the ZAGGsparq is marketed as being "able to charge an Apple iPhone up to four times," I see it being used for a lot more applications. Physically, it's 3.5 x 3.5 x 1" in size. Its Lithium Polymer battery pack is rated at 6000mAH - that's SIX AMPS in your little pack. Only the Amstron PP66S has that capacity ... but the ZAGG offers more features than the Amstron. ZAGGspark works with any of your devices that uses a USB cord for charging. Plus, it provides TWO USB ports for charging your mobile devices when plugged into an AC outlet. Weighs a tad over a half-pound. Four LEDs indicate the pack's power level (25% / 50% / 75% / 100%). I just ordered one, and will immediately put it to use. It's going to power my Verizon MiFi 2200 and Apple 32GB iPod touch. I'll report back how it performs. Clint Bradford 909-241-7666 ___ Sent via amsat...@amsat.org.

[amsat-bb] Another Bradford DUH! Moment
I am preachin' to the choir here with this post, I am sure. But since Southern California was under STORMWATCH again last night (we're expecting at least 0.03" of precipitation), I decided to build one of those cheap "tape measure 2M Yagi" antennas from plans seen all over the Web. I mean, I mention them during my satellite presentations as an affordable entry into high-gain ... I have a couple links on my Work-Sat Web site for plans ... I can see in theory where they should work - but I've never built one myself. So I stuck the PVC pipes together ... soldered the matching element ... straightened it all out, and took it outside for a test. OH MY GAWD. This is something that EVERY ham should do. What a dramatic increase in a handheld's performance a couple dollars' worth of stuff can accomplish! I heard a NOAA WX station (technically, out of range for this 2M Yagi) in San Diego that I have never heard from the house before. Every repeater of the six I immediately hit were received more clearly than with even the best of HT antennas ... and as good or better than my Cushcraft A148-3S (retailing for sixty bucks).
