Portable Power

K6LCS <clintbrad4d@...>
 

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 InvisibleSHIELD - 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 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.

Re: First Satellite Contact

K6LCS <clintbrad4d@...>
 

OK. I did find a reference on a TX tone at ...

http://www.amsat.org/amsat-new/echo/index.php

BUT it also states - right above the frequencies -

"AO-51 Operational Frequencies- The following are the announced frequencies for AO-51. Please check the schedule before transmitting to AO-51 ... "

- and provided a link to the Control Team status page.

But I sure had to DIG to find that page!

If a visitor to amsat.org just looks on the left and chooses ...

Satellite Information
-status, frequencies
and satellite history

... they will be taken to the best-available info!

NO - We are NOT using CTCSS on AO-51. Haven't for almost three years. And if you find a site with that mis-information, please write the owner top advise ... it means they haven't updated their info for three years!

Hello Everyone,

Well I finally made my first satellite contact this evening on AO-51 using the FT-817ND and the Arrow II yagi.

I did find out however it definitely works best if one has the PL tone set for the uplink.....DUH!!

All I can say now is this satellite stuff is pretty doggone cool.

Re: Which BNC-to-SMA Adapter?

K6LCS <clintbrad4d@...>
 

As long as the adapter "mates" well with the radio's case, it will provide some protection.

I like the design and finish of the Diamond you cited - here's a photo ...

http://rfparts.com/diamond/bncj-smap.html

I'll keep on using Stephen's adapters, 'cause I like the guy (grin). AND because he has done his research and has different adapters for different radios for us.

THANKS for the tip, Ed!

Clint


Re: Which BNC-to-SMA Adapter?

ed palmer <flhtci97@...>
 

I have found another SMA to BNC adapter that works well with the VX-8R. It is the BNCJ-SMAP adapter from Diamond Antenna. I don't know how it would work for other handhelds so your mileage may vary.
 
The adapter is wide at the base and mates up well with the rubber gasket around the SMA jack on the VX-8R. The last half turn will require one to hold on to the rubber gasket around the SMA when tightening down the adapter to keep the gasket from spinning.

Please consider either a NCG/Comet HB-05 BNC female to SMA male 18-inch jumper, or the Stephen Gulyas adapter. Either will protect your radio's SMA jack and center pin from stress.

The HB-05 is available from fine ham radio stores nation-wide. Info on the Gulyas adapters available at ...

Great points - thanks!

Re: Which BNC-to-SMA Adapter?

I have Stephen Gulyas's adapter, and think it's pretty good for
mounting a BNC whip on the radio. I much prefer it to the straight
metal-only adapters. Highly recommended.

On the other hand, I think it is slightly inconvenient for adapting a
stiff or fat cable to the radio that has a BNC on its end (or perhaps
a UHF plug on which you've attached a UHF-BNC adapter). For that
situation, I'd probably recommend one of the short pigtail atapter
cables. The short length helps isolate the fatter cable's stiffness
from the little SMA jack, and is easier to attach and remove.

Re: Work SO-67!

K6LCS <clintbrad4d@...>
 

... How do I set my FT-60R up for SO-67?? Its only one freq isn't it?
Watch the sat's operating schedule for updates ...

http://www.amsatsa.org.za/

Last week, they had a cross-band repeater set up for many.

Uplink: 145.875MHz
Downlink: 435.345MHz
CTCSS 233.6

As with other FM sats, please program to compensate for the Doppler effect on the receive side.

Re: More Mods to Arrow Satellite Antenna

K6LCS <clintbrad4d@...>
 

... I have been using the Arrow and have been pondering such an addition, but I didn't have any design in mind. Now I do. I see you drilled a hole just behind the first element to put in a screw and wingnut. How far does the duplexer extend IN the handle?
You can actually slip the duplexer out and see ... There's about an inch if clearance 'tween my wing nut and the end of the duplexer.

AO-51 Performance 11/20/09 00:42 GMT

K6LCS <clintbrad4d@...>
 

I wrote last week ...

"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."

And AMSAT's VP of Operations replied ...

"The power on the repeater downlink is a bit higher than normal at 760
mw. It shouldn't be a dramatic difference from our recent 500-600mw, but
noticeable to a observant operator ... - 73, Drew KO4MA

Well, my aging ears cannot take the credit ... I was using my standard setup - Arrow Sat Antenna and FT-60R.

Better Whip - or ELK / Arrow Antenna?

K6LCS <clintbrad4d@...>
 

... I am considering either the Elk or Arrow sat antennas. Are they going to be that much better than the Smiley 270A?
It's a tremendous difference! You can experience the gain improvement by making a simple Yagi yourself. There are a few articles here ...

http://www.work-sat.com

... including making a Yagi out of a steel tape measure ... or an old umbrella!

A friend in Texas has over 9,000 contacts with his Icom IC-W32a HT and the Anli/Pryme AL-800 antenna ... So you can certainly stick with your current setup!

This reminds me of when I purchased my little FT-817 - INSTEAD of, say, the FT-857. I mean, ANYONE can make long-distance contacts with 100W TX power. But something about only having 5W appealed to me ... a little more patience and finesse is involved ... (grin). Same with these FM satellites: Definitely workable with an HT and Smiley antenna ... but more easily worked with the gain priovided by an efficient Yagi or log-periodic antenna.

USB Hub Suggestions

K6LCS <clintbrad4d@...>
 

... I have been running a FT-817 and SatPC32 and sometimes HRD. I now want to add my FT-857 and run dual radio mode. I am using a Vista laptop. with a USB cable from two radios and one from a rotor control. It is a nightmare every time I unhook the laptop. Can you recommend a USB hub to connect all of this stuff to or a proper method. I am no computer whiz!

I'd stick with a name-brand for reliability ... and one that has an AC wall wart, so your USB lines get all the energy they expect.

I use a Kensington K331118A ...

http://us.kensington.com/html/6495.html

Belkin also makes quality powered USB hubs.

Macally makes a couple models of external hard drive enclosures which I have found to be great - but I am not sure if they currently offer powered USB hubs.

New Ham Antenna on ISS

K6LCS <clintbrad4d@...>
 

ARISS US Hardware Manager Lou McFadin, W5DID says that all the
teamwork and effort to expand the ARISS amateur radio station
aboard the ISS were successful this weekend when the new dual
band 2m/70CM antenna was installed on the outside of ESA's
Columbus module.

Lou congratulated the team, "This is an example of what can be
achieved by volunteer hams working closely with a space agency.
This antenna project was funded entirely by AMSAT-NA and volun-
teers who built the antennas for both an ESA experiment and for
ARISS. I am very proud of all the teamwork and effort that has
gone into this project."

The new ARISS antenna is very similar to the antennas already on
the Russian service module. Once the antennas are in place the
ARISS team will be working to bring amateur radio to the Columbus
module.

In conclusion Lou noted the tremendous contribution from ESA for
the experiment, the launch and the EVA making this expansion of
amateur radio aboard the ISS possible.

[ANS thanks Lou McFadin, W5DID for the above the information]
