Galaxy 17 74West - US Feeds
-
01-10-2007 1:19pm#1In the past few weeks there have been reports from UK (feedhunters group) on a 1.2M of analogue feeds showing up on Galaxy 17 74W. As it's way out of footprint, it's probably a result of some weird sidelobe on the transmit antenna, so very difficult to predict reception, but interesting nonetheless if anyone has any luck with it.
On a 1.2M I can barely make out a bump for the digital transponder on 11733, H but I reckon the signal is being attenuated by trees in the way. No line-of-sight from the 2.4M unfortunately.
Reported Feeds:
11.740 V Tp 2-K Aud 6.20MHz. feed, American football, West Virginia v East Carolina.
11.820 V Tp 6-K Aud 6.20MHz. feed, talking head to camera.
11800 H. 6.2MHz audio. "abc 5" testcard.
11.882 H 6.2MHz audio, colour bars / tone.
11.840 H 6.2MHz audio, feed0

Wow indeed. :eek:
I've given up on analogue feed's YEARS ago.
Heres the KU footprint for N.America
This is very interesting indeed, but don't be surprised because if a bloke in Argentina can pick up Sky News on Astra 2 (though with a 5m dish) then you'll never know.
Maybe its the new satellite being more powerful than the others around it , its just enough to reach us or maybe the downlink antenna is shaped slightly different or I'll even but my neck out and say there could have been a slight damage on the antenna shape that could have occurred during or after launch....
Anyway, good find if its true.
P.S. I think its says WPSU TV0 -
In Limerick it's only an elevation of 6.5 degrees! In UK only 2 or 3 degrees elevation.
Not bad for a 1.2M dish, although in fairness, the original sighting in the UK was a bigger effort, considering the lower elevation as you go east. The lowest possible down here is 62East at 2.4 degrees, but the signal tends to fluctuate a bit. I think someone here posted about reception of 64E at ~1 degree sometime back.
Yes - I saw a testcard for Galaxy 17 at one point, but didn't have enough time to tape it. The feeds correspond to those reported in the US, so it appears to be a sidelobe on the sat, rather than some special europe beam, helped by the fact that the sat is new and operating at max power.watty wrote:Are we sure this is 74W?
No, not really until you hit the 2 degree mark. Avoiding trees and hills is a bigger problem.watty wrote:I had thought that anything less than 10 degree elevation that you needed to be on very high site to avoid "ground noise".
Yeah, that's what I reckon too : high power + dodgy transmit antenna!weehamster wrote: »Maybe its the new satellite being more powerful than the others around it , its just enough to reach us or maybe the downlink antenna is shaped slightly different or I'll even but my neck out and say there could have been a slight damage on the antenna shape that could have occurred during or after launch....
Right again - all 4 feeds were for college football, including WPSU TV. Reception is better than the pic above suggests. This is because it was originally recorded as NTSC to a multi-standard VCR, then played back and converted to PAL and sent over 20M of coax to a PC with a USB PAL tuner. Image quality suffered a little along the wayP.S. I think its says WPSU TV

Hi there can you give me the web address of the feed hunts forum you seen this on or pm it to me please thanks.In the past few weeks there have been reports from UK (feedhunters group) on a 1.2M of analogue feeds showing up on Galaxy 17 74W.

Some few weeks back, Horizons 2 was launched and slotted into 74W. At that time, Intelsat put in a request to the FCC (attached) to have Galaxy 17 shifted off to the 91W. They've recently put in a second request to boot it on to 123W - which is where NORAD tracking puts it. So I was sure that was the end to the fun with analog feeds - what were the chances that Horizons 2 would also have a weird sidelobe? Kept an eye out on the spectrum analyzer for an spikes coming from Horizon 2, and back in action last night.
