... had better luck on the lower passes than the ones which go almost overhead ... maybe the polarization coming into play ...
I have yet to have to truly experience the phenomenon of "circular polarization" while working the FM sats with my Arrow Antenna.

On EVERY demo - and during every personal/private pass - I'll twist my Arrow 90 degrees. I won;t announce it to the group. I'll just do it. And there is NO discernible change in TX or RX signal by doing so.

Oh, I know the engineers here can SHOW me on paper that the phenomenon is there. But in real life - for ME - it just doesn't happen.

I had one audience member tell me he experiences it during loss of signal more htan at any other time during a pass. And I have to believe him. But please do not let this issue "make or break" any attempt to work an FM bird!

Clint:  For me, I have had better luck on the lower passes than the ones which go almost overhead.  May be the polorization coming into play.  Otherwise the info on Heavens Above has been very accurate for me.  Also the info on Iridium flares has been very accurate. Just my opinion.

I have found most software's "footprints" to be really conservative. I mean, we can work the FM says well "outside" that circle.

I am going to post the portion of my presentations where I "decipher" the numeroc data that the AMSAT site gives. Always good to have a second opinion ... And once you see how easy it really is to work with the AMSAT data, you will enjoy/like it more.

Clint

P.S. - With low power, start with 20 degree or better elevation passes. As you progress, you will work passes a little lower.

thnaks Clint, of the ones Ive tryed heavens Above seems to be the one i like the most. Plus I use Rador tool kit for real time radar and wacth wacthes and warning for Skywarn. the program already has a link to heaven above. So that kinda cool and makes things easy for me. I reg. with heavens above found A0-51 and am tracking. Cool last step. not just have to pick a good pass.
 
when heaven above tracks by you long & lat. are passes it s list aways in the footprint of the sat? So my QTH will be within the foot print of the dst if Heavens abocves list it as a pass right? I hop than makes sence. LOL also the min AZ I would want to try would be what like 30 degrees or somthing? I thought i read that somwere but dont remember were.

I have been "with" Heavens Above for several years - nothing to worry about by registering: I have never received any spam that could be traced to them. You register just so that the system knows your lat-long when you check in!

AO-51 is named "AO-ECHO" in their lists (if I remember correctly).

Jimmy:  When you go to Heaven-Above, log onto the site, then go down on the left hand side and click on the Radio Amateur Sats and you will get a listing for your site for All the Sats for about 6-10 days.   Go down to AO-51 and click on it. Go to All passes and ckick on that, you will have just the Ao-51 passes only.  Click on one of those, and it will show you the pass close up.  Hope this helps.

I wanted to try heavens above for tracking. well I gi there make a acount so that my QTH is in there when I log in. its all good LOL
 
so I try to rack ao-51 I cnat find it on that site, what up maybe it because im new to that site.  I cant find Ao-51 on the web so so does somone have a link?

AO-51 Recording Request

pfarcon
 

Hello all! I was testing with a new handheld today with the voice recorder in hand as well. I made a few contacts that were new on the just completed pass of 20:54 - 21:09 UTC, May 22 through my area. Would anyone have recorded any portion of that pass during that time frame today? I must have inadvertantly somehow not started the recording for I have no record on the digital voice recorder. Any assistance would be greatly appreciated. I am still somewhat new to this and working like many toward a VUCC.

Re: new to sats & this group

Jimmy c <kc9pxz@...>
 

your right the IC 28H is a 2 meter rig, I git mine used all the boards and that were in this one. If  somone bought it new in its day i think they had to buy the need board extra
 
yep it is a classic the HTX 202 I been lokking for a while I would really like own its 440 brother the HTX 404. I found on amsat and your site a write up a cheap homebrew yagis I thought i would either home brew a 440 yagi or use the one Im trading a ham friend for. the dimound 510 is a 17 foot verical daul band ant. think on put a yagi up on the tower with it.
yep i saw the link I read about them im sure i will try them aswell. yep I think a yahoo list like this is a pretty good idea.

new to sats & this group

Jimmy c <kc9pxz@...>
 

Hi all
just wanted to say hi. I was send a link to K6LCS's web page and found the link to this group. I have yet to work my first sat. right now what i have to use is
a ICom ic 28 HT 2 meter
a HTX 202
a hand held VHF/UHF scanner for listen to the downlinks
a dimound 510 on my tower & and a tri band whip aswell as a home brew 3 element yagi. I working on getting a yagi from a friens his not use 4 elment.
a old camera tri pod to mount wicth wver yagi I use.
 
right now im using gsat for tracking, but that will change Im trying to find tracking software I like.
 
SO im thinking out of that list I cam make somthing work to get my fet wet.

AO-51 During Eclipse in Southern Hemisphere

K6LCS <clintbrad4d@...>
 

Please Do Not Use AO-51 While the Satellite is in Eclipse

After a brief outage on May 16 the AO-51 Command Team has turned the repeater back on on AO-51, including the 67 Hz PL mode. The Command Team has a favor to ask of our Southern Hemisphere users, including those in South America, Southern Africa, Australia, and New Zealand:

Please avoid using AO-51 while the satellite is eclipsed.

Most tracking programs indicate illuminated or eclipsed states, and it can always be found by whether the footprint of the satellite is crossing or in contact with the footprint of the sun. Generally this is occurring when the satellite is south of 30 degrees south latitude at present. AO-51 eclipses are predicted to reach almost 20 minutes by July 2010.

AMSAT-NA VP of Operations, Drew Glasbrenner, KO4MA said, "I realize this is a large favor to ask, but the alternative right now is moving to a scheduled type operation, which I would like to avoid. Please pass this to your friends, other users you know, and your national satellite email lists and forums."

For this summer eclipse season, the eclipsed periods are while AO-51 is over mostly unoccupied Antarctica and surrounding areas. This means when the batteries alone are supporting the transmitter there are not likely to be any users. The power management software combined with the PL, should mean the satellite's batteries can be protected from over-discharge, while still providing the strongest possible downlink signal and highest possible availability.

Observations from the southern hemisphere while entering and leaving eclipse are very helpful. Post your reports on the AMSAT-BB or e-mail your report to the AO-51 Control Team. AO-51 operators also monitor the Live OSCAR Satellite Status page. Analysis of AO-51's Whole Orbit Data (WOD) files shows the distribution of the satellite's users.

If the eclipse periods get too long too fast the repeater may shut off due to a low battery voltage watchdog. If this happens, please email Drew directly.


AO-51 Mode Change

K6LCS <clintbrad4d@...>
 

Hi All,

You can expect the mode change on AO-51 from S-band to U/V to occur around 1120 utc tomorrow (Monday, 5/17).

Re: New Kenwood HT TRUE Full-duplex? Not known ... yet.

K6LCS <clintbrad4d@...>
 

Well, AvMap Don writes that the new Kenwood HT is, indeed, true full-duplex.

Let's just wait until at least Kenwood submits their unit and docs to the FCC ... (grin)

Re: New Kenwood HT TRUE Full-duplex? Not known ... yet.

K6LCS <clintbrad4d@...>
 

No - the Kenwood TH-F6a is DUAL RECEIVE. But you cannot hear Band B when you TX on Band A.

I know - although preferable, it is NOT *mandatory* that we work the FM amateur satellites in true, full-duplex mode. But it would be nice to have another rig - in addition to the Alinco DJ-G7 - on which to use this operating mode.

New Kenwood HT TRUE Full-duplex? Not known ... yet.

K6LCS <clintbrad4d@...>
 

Just has a conversation with N0BVE, Don, via his EchoLink setup. Don is at Dayton. Don walked to the Kenwood booth, and asked the Kenwood rep directly (well, they heard me asking on Don's radio), "Is this unit true, full-duplex - where we can monitor the sub-band while transmitting on the primary band?"

The Kenwood rep answered too quickly - after just hearing the word, "duplex." Unfortunately, marketing terms and ham terms are not always carry the same definitions. When I re-asked the question, the rep was not sure.

Don, although using a Yaesu VX-7R at the show, knows Kenwood radios (and remembers his TH-78a - which WAs a TRUE, full-duplex radio). So Don grabs the new Kenwood HT, and tries to program "our scenario" for working the FM satellites: monitor 435.000 while transmitting on 2M. He couldn't get it to do it - but that was because the radio needed to be reset, after so many messing around with it.

SO, we really do not know. We do not have a preliminary instruction manual. We do not have a submission to the FCC for certification. GPS/APRS features look intriguing. But we still do not know if this is a TRUE, full-duplex unit.

I know - although preferable, it is NOT *mandatory* that we work the FM amateur satellites in true, full-duplex mode. But it would be nice to have another rig - in addition to the Alinco DJ-G7 - on which to use this operating mode.

Re: To Arrow or Elk - Which is better?

K6LCS <clintbrad4d@...>
 

You will enjoy the Elk!

Just FYI, Arrow does have a couple dealers who will ship to Canada.

Let us know when you receive, assemble, and first use your new Elk!

Re: To Arrow or Elk - Which is better?

Group:

Thank you for all the comments regarding the Arrow and Elk. It sounds like each antenna has its own merits. I have decided to go with the Elk, simply as it is available locally (Edmonton, Alberta) and it is the best price here. Arrowantennas.com will not ship to Canada (I spoke to the company directly). Radioword.ca, which sells the Arrow in Canada, makes the 146/437-10WBP about $80 more than the Elk 2M/440L5 once shipped.

Once again, thank you for all the comments.
