Looking for New CNN Sat

[SkyWatcher57]

Scans in as S2 8PSK 3/4, just in case someone needs that info to scan. 11.5dB here, but solid. (dish mover might be out just a bit from the high winds over the last month or so). Was going to post the new coordinates, but y'all beat me to it.
Convenient to have these on 97W. Will have to do some editing on my main receiver/KODI setup though... Good to have to do this so I don't forget how!

Hi Cham, so your getting the CNN channel on G19? I just peeked out my 2 dishes, main was was off a little, signal quality came up some, also put on a better LNB. I'm hoping to get a 39inch offset dish and mount it up about 15 feet on a pole that's attached to the house for G19, should clear tree tops in that spot and retire the older 4 footer. Wondering if a better recevier is on order?
Thanks

Nice dish farm! CNN Newsource channels 1 to 7 are active now on 11796 H 30000 on 97W.

Get permission from this forum's administrator to access the "What's Up There" section. That's where all the information on satellites found is posted.

Hi Cyberham, ah, really, so I need permission to access this area?
yup, pretty cool getting signals from so far away, always a learning curve. The larger one is the G19 one, homemade feed assembly to hold the LNB, small one is my SES2, works great. Small grey one by the 5 footer is receiving the Imarsat satellites and the grid one is capturing the GOES 19 weather data and images. Thanks

Ah, got them now!, they weren't there last night on the scan, but just redid another scan since you said they were and an yup, there they are, all 7 of them, NICE !!! Thanks

If you must go that high on a pole, then it's necessary. But keeping the dish near ground level is SO much nicer for tweaking, adjusting, re-pointing. I used to live northeast of you in Nova Scotia and having my dishes near ground allowed me to eventually experiment and find satellites as far east as 3W.

Oh I know, I have a solid pole at the corner of the house now with a railroad antenna at the very top, and is attached to the house, solid attachment, that I will be mounting it off of it. Easy enough to get to it with a short ladder for any adjustments. Ya, my view is getting limited now. I started off back in the early 2000's with a C-Band 8 footer, using the same pole that the 5 footer one is on now. Just sent a direct message to who I think is an admin about that "What's Up There" section. Thx

No issues with 87 KU here either. Tuning all available feeds well with only a 76cm dish.

97 KU

Are you online? I was watching SES 2 up to about an hour ago, are you receiving it there? G19 is ok, thou on another receiver. SES 2, signal is 95%, 0% Video. If cut out a few times earlier, now nothing.

Yes they come in fine using a 90cm dish here, I don't think you "need" a larger one but a 1m (39") dish should get better signals than mine. Of course it was heavy overcast and light rain when I scanned these in, so the signal will be better when the sky is clear. Good to have 6-8dB headroom (signal to noise), but 2-3dB can work but maybe not with an S2 8psk signal. Most of the usual transponders on 97W are DVB-S that will work with less signal to noise ratios.

That wifi grid dish looks like it is pointed at the Clarke belt.. are you picking up something with it as well?

Cheers!

Are you online?

Usually

I've been in Ohio since Friday for a family event, but will be back home at the "dish farm" on Tuesday

Grid antenna, yes, pointed at the GOES 19 weather sat, 1.694Ghz, weather data and weather images.

By chance does anyone know the exact name/type of the dipole feed used on the grid/helicone antennas?
I'm also trying to get my feet wet receiving GOES. So far I made a 7 turn LHCP helical antenna for a Viasat dish as well as swapped the pin feed on a RHCP patch antenna to convert it to LHCP.

Inamrsat comes in strong. Both were made from online calculators and examples.
Lots of crash course reading and learning. And just added a nanovna-f v3 to my collection. More portable than my trusty old HP network analyzer.

Even though the helical and patch were made as accurately as the plans and calcs. showed. The nano arrived today and the patch SWR and impedance was 100 MHz lower than Inmarsat at 1541 MHz-ish.

The helical has a triangular impedance match strip. Its impedance was off for GOES freqs. Now I can fix it.
But. I didn't read well enough. GOES does use circular polarization. But like the grid, it uses linear also. And so. Even though the photos on RTL-SDR links shows the dipole mod and measurements needed to lower the wifi grid to GOES freqs. Nothing is mentioned on the type of antenna it actually is. I could whistle one up in a half an hour.
Another site I ran by even showed the top reflector dimensions and bend angles. Kicking myself for not bookmarking it and haven't found it it again. In a day my browsing history can get stupid long. Especially on projects.

Hey folks, been offline a bit, anything new out here? bit chilly today but got my offset fed dish moved to another "temp" spot and better view thru opening between the trees. Will see how it does once the leaves start sprouting. Got a little it locked on G19 now as well, and got a little better signal from it than my 4 foot one. Now have 2 receivers running, 1 per each dish. I did noticed that when I connected up to the SES2 Sat, all the signals were there again and strong. Wonder why they keep going off line and back on again? Thanks folks.

Hey Arlo, nice to see someone trying the GOES Sats too. I tried lots a feeds back long time ago, large dish, etc. Just started back up on them once I realized what you could do with SDR's these days, and some pretty cool Sat programs out there. Now I have a small grid antenna, feed and antenna bought from a vendor, and now get earth images and messages from the GOES Sats. And small dish with same type feed assembly for full Inmarsat reception. I think the feed is linear, there are photos of the inside of it. One of my received images. Frank
