I used an FT 8800 for sats, I still do for my "dx-peditions", works great, listen to one freq, transmit on another,    (full duplex), great sat radio...

That's a good plan. Try a temporary setup where the receive Yagi is 15 or 20 degrees above the horizon. And don't over-do it with gain. I think you'll be pleased with 6-9db gain.

My 440 EggBeater from M2 is nice. Ground plane kit attached. But it sure isn;t as exciting as a handheld beam or Arrow/Elk setup!

I went through just what you are going through, and did the same thing you are thinking about. I have an Elk, I  eventually mounted it on a roof tripod, a 3 ft tripod, with a cheap rat shack rotor, and mounted it elevated at about 25 degrees, and It worked great. Most of the passes are at 45 degrees or less, so you will be able to work maybe 90 percent of the passes with that set up, maybe not the really low ones or the  straight overhead ones  full pass, but, try it, it is a big improvement over standing out in the back yard holding a  radio in one hand and an antenna in the other. Is that the world's longest sentence?
The other thing  previous to that I did was mount that tripod on a table in the back yard, so the antenna was at maybe 6 ft, mounted it same way, at 25 degrees, and all I had to do was twist the mast  along the azimuth, a big improvement over trying to  hold the beam and find both elevation and azimuth.  I love the Elk.
Good luck, 73 Bob wa7dxz dm33

Instead of having ALL the URLs and links from my presentations on a single page, I broke the topics/segments apart in a more traditional fashion.

And it's a lot less scrolling for visitors.

Doesn't match what my grandmother performed a few years ago. Hers was an eight-mile sentence. It was story after story after after-thought ... I was driving her somewhere, and I darned near had to pull over to the side of the freeway from laughing so hard ...

... love the Elk ...
Once one tries out an Elk or Arrow sat antenna themselves, there's no going back (grin).

Re: Preamp

K6LCS <clintbrad4d@...>
 

If you haven't already started that one ... how about building a simple Yagi instead?

But for the QST antenna, Ramsey has a low-cost kit for a 440 pre-amp ...

http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=PR-SERIES

It should "buy" you at least 10 degrees a pass on acquisition and loss!

Re: Preamp

Yes, it is the Parasitic Lindenbald antennia. I am in Indianapolis, Ind, and its kinda cold standing out in my driveway at 6am trying to talk to the Oscar 51 satalite. Who sells a preamp or where can I get a kit to make one? Thanks for any help.


Re: Preamp

K6LCS <clintbrad4d@...>
 

If it was the Parasitic Lindenblad Antenna for 70 cm earlier this year, then yes, you might need a pre-amp, because it has very little gain.

Where are you in the country? Do you have really bad weather?

Clint, K6LCS


Preamp

fejohnso
 

I am in the process of building the 70cm antennia which was in one of the QST magazines. It will probably be connected to my VX7R handheld as thats the only radio I have in that freq. Do I need to use some kind of preamp, if so, where do I find one?


Re: AO-51 Question-o-matic

K6LCS <clintbrad4d@...>
 

The PL information came from AmSat's page...
Right at the top of that page is a link to the Control Operator's page ...

Trust me: The latest AO-51 info is available right here and at work-sat.com. Honest.

Clint,
I had originally copied that set up, but had not revisited it in some time. It matches now.

The PL information came from AmSat's page...

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

Unless I'm misreading the information along the right side. I did not click on the schedule link, still learning...but just wanted you to know where I saw the PL info.

Thanks for all of your help,

Re: AO-51 Question-o-matic

K6LCS <clintbrad4d@...>
 

Have you programmed your radio per the programming chart on the tutorial at ...

http://www.work-sat.com

The chart is for the primary V/U mode - which AO-51 is in now.

NO Doppler correction for the 2M uplink.

Having the CTCSS on TX won't hurt anything ... But the "larger picture" is that if a Web site is stating it's necessary, then they are not interested in offering current information. We might turn the CTCSS requirement back on - to eliminate some interference problems accessing AO-51. You'll read about any changes right here, or on my Web site.

Clint,
Darn and blast. That means I was being heard (sort of), right? I mean, if I am using PL where it is not required then I still get through vs the other way around... Or am I mistaken?

I thought that was too easy of a reason. :|

Thanks,

Re: AO-51 Question-o-matic

We haven't used a PL on AO-51 for about three years now. So, whatever site you saw "Use a PL for AO-51" on is not providing current info to you.

Stick with us ... (grin)

I notice a different uplink for FM QRP (no PL), should I be using this
with my FT-60 since it tops out at 5 Watts?
If you go to my site at ...

... you can scroll to the bottom, and find a link to the AO-51 CONTROL OPERATOR page. THAT is the BEST-AVAILABLE information!

Here's what the CONTROL TEAM has for us ...

AO-51 Question-o-matic

CatzMeow
 

Good Space-Oriented-Folks,
Had a clean pass of AO-51 as I was leaving work today, so I thought I'd give it a go (my timing has been not-so-good lately and I've been stuck with 6 am passes so I haven't made much of an effort in a while).

Had some trouble lining up the signal, and never quite came in clear, but I did hear some voices and could make out calls so I tossed mine out there....nothing.  Waited for someone to inhale and put it out there again, faster this time (I'll show you fast-talkers)...nothing again.

So I figured either the other kids on the box had gills and could talk and breathe in at the same time, or my PL was off.

Got home and dumped the FT60 into Commander and pulled up the details on Amsat.  Sure enough, my PL was old so I switched it all to 67.  Here are my questions:

I notice a different uplink for FM QRP (no PL), should I be using this with my FT-60 since it tops out at 5 Watts?

It has the same downlink?  Won't we just be stepping in with all of the high-powered kids and their cooler mega-watty toys?

The AMSat summary page  for AO-51 has a different d/l for QRP (435.15) but the Echo Project Page  showed QRP and regular on the same d/l.

That's it for now, I'm sure I'll have more as I start working through my other memories.

Thanks,
Ed

... This is FUN ...
I still get a thrill working three countries on some West Coast passes (Mexico, the U.S., and Canada).

Did you see the reply to your Doppler inquiry? I added that URL to the "Links" area here - thanks for bringing that up!
