Re: [amsat-bb] FM Birds, New Grids, and Chaos

Les Rayburn
 

Those are good suggestions. I try to write down calls and grid squares by “reading the mail” on other QSO’s. Then I call that specific station. 

I rarely (if ever) just throw out my call. Sometimes when I’m up late at night I’ll do that, or even call CQ but only when the bird is dead quiet. 

I’ve got a TH-D72A, and an ELK antenna configured for portable operation. Just waiting on warm and dry days to give it a try from the backyard. This winter has been one of the wettest on record here. 

Do wish more operators would be more considerate when the bird is busy. My “wish list” would include: 

  • Make one QSO, then just monitor the rest of the pass—unless someone calls you. 
  • Check Twitter to see if anyone is activating a rare grid. If so, let them control the flow of contacts on the bird. This is especially true of Western grids. Often the pass is very short for those grids, and stations in the East have a limited time to work them. But the bird is often filled with Eastern stations working other Eastern stations during the whole pass. 
  • Resist turning up the power to “muscle” your way in. 

During one pass earlier this evening, I listened to a single QRO station make 5 or 6 contacts during a very crowded pass—simply by muscling other stations, talking over other operators, etc. 

We clearly need more FM birds because the demand is very high. Meanwhile a lot of the linear satellites are empty or nearly so.

You might look for a pass that is way east of you over the ocean.  Fewer people on at that time.  Also coming up from the south. There are operators in South America that you might reach.  But anyway, the less land in the visibility circle of the satellite, the less busy it will be.

Good luck and 73!

I’m meeting with the VUCC card checker this week to sign off on my 2 Meter VUCC. That took over five years, since I’m limited to a single 6 element Yagi in the attic. At least half of those contacts came via WJST meteor scatter.

Thought it would be nice to get both 2 Meter and Satellite at the same time.

Most of my contacts have come on the linear birds, with over 2/3 of them on FO-29. I realize that there is a lot more activity and grid activation on the FM birds—so I need to spend more time there.

But the chaos of that type of operation just doesn’t appeal to me. Plus the noise levels in the attic make it difficult for me to hear the FM birds very well. SO-50 comes in “pretty well” but the AO birds are often covered with noise and difficult to hear.

Any tips to improve my success rate on FM? Other than completely avoiding weekend operation! :-)

Not sure if you do this or not, but consider calling people you hear
rather than just throwing your call out.

You might also consider repeating every call you hear back in your
head so you can do the above more easily. Concentrate and keep trying
and eventually you will be able to surf the chaos. Wipe outs will
still happen. Sometimes you can hang ten.

Can you operate portable so you don't have to deal with the noise that
you pick up in the attic?

ARISS advises this is an “extension” of the same project, so if you have already submitted images and your application for an award, no “different” award is available.

STILL some fun, though!!!


Re: ISS SSTV - Let’s Do It Again!

Clint Bradford
 

As far as image submissions and awards, I will find out if this “extension” is a “unique” project. They are the same images as we enjoyed last weekend.

Bonu opportunity Feb 15-17

 

The ARISS team expects that a second SSTV transmission event will occur from ISS this weekend. 
 
ARISS Russia team member Sergey Samburov, RV3DR, worked with the mission control center flight controllers to schedule in ISS crew member time to configure the JVC Kenwood radio to support SSTV operations in the Service Module.  SSTV setup is expected to start around 8:45 UTC on February 15 and conclude around 17:25 UTC on February 17.  These dates/times are expectations and may vary.
 
The ARISS team wanted to give the community another opportunity to downlink the SSTV images we developed for you given the weak signal situation that occurred last weekend.  For clarity, these will be the same 12 images that were downlinked last weekend.
 
As a reminder, you can get the latest SSTV information on the ARISS SSTV Blog Spot:  http://ariss-sstv.blogspot.com/  Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php  And you can receive a special SSTV ARISS Award for posting your image. See https://ariss.pzk.org.pl/sstv/.  For simplicity, we have added a new tab for SSTV, under general contacts, on the ARISS web site www.ariss.org
 
For those that are asking, we are still not totally clear what caused the issue last weekend.  We believe it may have been either a loose feedline cable or an antenna switch that did not fully engage. Once the crew reset the system and checked the cabling and switches, the radio system started to perform nominally.
 
Enjoy!!

Re: SSTV Pass NOW

Fred Hillhouse
 

From Clint: “Image captured while mobile ... “

 

Hi Clint,

 

Was your mobile radio in wide or narrow FM?

 

The reason I ask is I was only able to get an image through my TH-D72 when it was in narrow band.

 

Some of the Kenwood TM-D710 radios had a problem with a filter and the way of quickly checking was to put the radio in narrow band. Although I haven’t read of any issues with the TH-D72, I am wondering if it has a receive issue.

 

I did manage to get two images: one through the HT and the other through my PC (SDR#/RX-SSTV). Even though the pass was different, the image was the same.

 

Thanks!

 

Best regards,

Fred N7FMH

Re: ISS Pass for So CA Tonight

That WAS exciting ... Captured the end of an image at only a degree or two of elevation, then snagged one right overhead - while watching the ISS ...


Re: ISS Pass for So CA Tonight

John Smith
 

On the last 2 passes here on the East coast I saw what appear like packet bursts on 145.825 MHz in addition to SSTV on 145.800 MHz. Should I expect to see packet and SSTV at the same time?
