Are you gonna send postcards? Seriously if this is your first FTA receiver the problem is most likely configuration. I have found FTA receivers to be akin to Linux. If you were not there with the early development years doing things may seem very difficult. This is not a DSR922!
As previously posted you have not provided any information which any of us might find helpful in resolving your issue. If I remember correctly you are slaving from a DSR922. So first things first. To be able to watch anything on a H polarity first your dish must be pointed at the correct sat. I have found renaming the sats in the
Mercury to match your DSR922 works quite well. Now that you have your dish positioned properly you must also have the 922 on and on a H polarity channel.
Next on the list FTA receivers are far more touchy about alignment than the DSR922 is. Could part of the problem be alignment that is not quite right? Not bad enough to keep the 922 from locking but bad enough to cause problems with the FTA receiver? A little trick I like is to go to menu on a live tp and watch the quality as I bump the DRS922 until I reach peak signal.
Are you aware the Mercury has a channel backup feature? QWhen used and you perform a master reset as you did the other day you can load all your channels back in? Do you understand the menus when you go through them? Have you been to the Fortec site and looked through their online material concerning setup and usage?
Is this your first attempt at doing anything like this?
