On the
Mercury II, in edit channel, there is volume offset where you can lower or raise the volume of a particular channel.
This barely changes the volume. But some channels on some satellites blast out a very loud sound, others are very very quiet.
Then need to update the software for the Mercury II so the volume offset goes to 100 or -100 instead or 8 and -7.
Examples of very different sound levels...
Very very LOUD channel! DWTV - AMC 1, 3740/V/29270
Very quiet channel... AGHAPY - Galaxy 26K 11870/V/4168
FYI - I am using a 12 ft. wire mesh dish with a BSC621-2 C/Ku LNBF to receive these satellites for my Mercury II receiver.
