Re: INMARSAT C-Band Channels
Good to hear you are receiving C band data from 4F3,
Unfortunately I don't know of any continuous c-band signals on 3F5 - that would make life too easy, the 2 most active frequencies for me are 1533.81 and 1534.36 both 10500bps burst. There are other frequencies that have 10500bps burst but the data is infrequent so I tend not to bother monitoring them.
The laptop I use is not very powerful, if I try to monitor too many frequencies it tends to crash.
Remember these frequencies are approximate, exact values depending on your LNB oscillator frequency - with temperature drift these frequencies can change up to 30KHz during the day especially if we have a chilly night followed by a warm day - I think my LNB must be particularly bad for temperature drift.
If all else fails, make a small helix along theses lines https://uhf-satcom.com/satellite-reception/l-band and swap it for the LNB and align the dish with L band signals (aero on 1545.0 to 1545.3MHz for 3F5) theses are fairly strong and continuous so it makes alignment easier
Hope this info helps
