I've had this motorised setup for some years that I only used for Astra1 and Astra2 and everything was ok for just that.
So recently I started looking at other stations, in particular one called Nuvolari, which was on Hotbird at 13E and I received that fine, but for some reason it is no longer there, but is apparently still available on Eutelsat 12WestA @ 12.5W, which I can't get.
Technomate TM-6900 HD Combo Super, DigiPower SG-2100A motor, 80cm dish, Triax TQD007 Quad universal LNB.
The dish and motor are mounted off a south facing side of house on a pair of T&K brackets approx 5m up, and with a clear line of sight from probably approx 40E to 90W (if motor allows).
I have been up and checked, and adjusted the pole holding the motor so the motor bracket now (it wasn't before) shows as level (i.e. pipe is vertical in the east-west axis, as if you looked at face of dish when it is at 0degrees.) In the north-south axis it is fractionally at an angle. i.e. if you looked the dish/motor from the side. But only by a degree or two (as a guess), which I assume the elevation of motor should can compensate for?
My latitude is 51.5 degrees, according to the "elevation and declination angle table" from my motor it says I should set the motor elevation to 38.5 degrees.... I have tried to do this as best can... but the motor bracket has rusted and the original degrees markings have gone, I can only make out the 35 and 45 markings on the side.... I have tried a range of settings around that....
The manual says I should set the dish to 40 - declination angle of 7.4 approx .... i.e. approx 32.5 degrees ... BUT
Also I experimented with the LNB skew and have it set where I got the best results for Thor and Astra 2.
If I set the motor to Thor at 0.8W I can receive a max signal quality of 77% with dish angle reading 20Degrees.
If I then move the motor to Astra2 28E I do not get a signal, if I adjust the dish to 15Degrees I get a max quality of 90%
If I then move the motor to Eutelsat 12.5W I do not get a signal unless I move the dish to 23Degrees and get a quality of 74%.
As a compromise for now I have set the dish at approx 17Degrees. I don't know if this could help point to the issue(s) but I have made a note of the Quality % against some of the sats from the list "Strongest TV Transponders Dec 23rd 2014"
Astra 2F @ 28.2 east 10964 H 22000 Channel 5 78%
Astra 1L @ 19.2 east 12226 H 27000 Euronews 80%
Hotbird 13D @ 13 east 11137 H 27500 Bloomberg Europe 80%
Thor 6 @ 0.8 west 12418 V 28000 Al Jazeera English 57%
Eutelsat 5WestA @ 5 west 11591 V 20000 France 2 44%
Eutelsat 12WestA @ 12.5 west 11407 V 27500 KTO 0%.....
Question 1: Any thoughts on what I am doing wrong or suggestions on what I should try next?
Question 2: Even when I pointed at 12.5W and got the strongest signal for KTO (74%), the channel I wanted 12718 H 36512 was "patchy". The signal quality seemed to be "flickering" and change from something low up to I think I saw 51% but it was rapidly and constantly changing. So the picture was just "blocky". Is this expected, could I need a bigger dish to get that signal?
