Re: AO-51 Question-o-matic

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.

Preamp

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: 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


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 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 ...

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

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

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!

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: yaesu ft 8800r

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...

The Yaesu FT-8800 can be programed for "split freqs" (page 33 of the manual) as well as cross-band ops - it's a great rig for working the FM birds!

Info regarding which cross bander base to buy

Dear Friends,

De VU2SGW, OM Sai I am very much interested working satellites. I just wanted some info regarding which is presently best cross bander base to buy.

Waiting for your reply,

THANK YOU for visiting!

... which is presently best cross bander base to buy ...
It has been MY mission in life these past three or four years to point out to fellow hams that they probably already have the necessary equipment to work the FM amateur satellites.

Most of the dual-band handhelds and mobiles manufactured the past few years have the capability of transmitting on 2M and receiving on 440.

Please download my tutorial at ...

http:/www.work-sat.com

... and see what equipment is necessary to work the FM ham "birds." You probably already have a handheld radio that is capable ... and all you need to do is improve the stock antenna!

I agree. What some of us are saying is that it is nice, but not  necessary, to hear your own signal into the bird.  Full duplex is nice, but not necessary, son't let lack of full duplex keep you from trying it. I often make contacts where I  hear the other guy, he hears me, and I do NOT hear myself.
 
Others may argue the other way, you should hear yourself. Yeah it's nice but not necessary. I was with a friend in Fargo ND during the floods, and we rigged up his IC-706MkII,  to work the AO-51, . Worked super. Used his dual band mobile antenna, he made several contacts. Was it optimuim, no, but yes it worked, He just waited til he heard a loud signal, and called.
Most of us probably have what we need to work the birds.

213u coax

John Moncak
 

clint i have 100ft of 213u coax will that be to much loss on the recieve end i think im going to mount the elk at 20 degrees on my garage roof in a tripod and run the coax and rotor wire to the house or do i have to get lmr400uf ok thanks .this is a great group for inf and making new friends 73 ke3lb .just got my elk today the rotor and the ft8800r and now we are going to get a foot of snow tonite and tommorow but im making plans so when the wx breaks im ready


Re: 213u coax

K6LCS <clintbrad4d@...>
 

Naw ... RG-213U is rated at 7.6 dB loss/100' @ 900 MHz - so you'll have less loss at 435MHz. And making it up with the gain of the antenna!
