If you are aiming to US sats, you better hope that it has a strong transponder and that there are no sats on either side of it that have signal on similar frequency (doesn't have to be same frequency since a transponder with high SR on adjacent sat can over flood bunch of frequencies with smaller SR on sat yuou are pointing too).
Some transponders are so strong that you can be pointing 2-3 degrees away from that sat and still get the signal in because beamwidth is so wide. |
Hi VJ...
Thanks re SR not important thing. What you say after that may have been related to why I thought SR might be a factor though. Ie recently I was scanning G10r, and scanned in a narrow transponder from IA13. The one narrow transponder was the only channel from the adjacent sat that scanned in, ie I didn't scan in ANY of the high SR transponders. I did a spectrum scan of IA13, and the narrow channel wasn't really stronger than the other transponders on the sat. I'm guessing that when aiming in an area with 2 deg spacing, that the odds of seeing a weak signal without interferrence is better when that signal is narrow, and a high SR transponder is much more likely to see interferrence and get wiped out.
However over the atlantic, where there isn't as much likelihood of adjacent sat interferrence, perhaps it doesn't matter whether the signal is wide or narrow.
Interesting.
