Well believe it or not I am using the HEAR IT INLINE MODULE from
http://www.gapantenna.com/hearit_inline.htm
I took a listen to your feed this afternoon, and I'm impressed with the sound quality (clarity). Then again, I don't know what it was like before you added the DSP.
I do notice pops at times. Is this due to the level/gain on the DSP being up higher, whereby the higher it is, the more pops there are? And what setting(s) do you have your's set at? I also notice that some transmissions are, although nice & strong, they're so muffled that they're unreadable. Maybe that too is due to the level that's set?
All these questions ..... I know.
Actually, I'm pretty happy with the reception that I'm getting, with very decent signals out to 200 miles, where most of the aircraft transmission start & end. But I don't mind spending the $200+ cost of one of these little critters, if it would improve my sound quality somewhat. Landed (item, plus shipping & duty) will put it over $300 ..... awful expensive if it doesn't improve my feeds' sound quality.
I've Google'd this device to try to read more details on it, but there's not much out there.
If it's not too much trouble, perhaps you could take a listen to my 2 feeds (around midday) some time, and once you hear the sound quality that I'm having now, perhaps you could advise me if you think one of these critters would improve things for me, or not. And I realize that if I do decide to go with this device, that I'll need 2 of them - 1 for each feed.
And don't worry ..... any recommendation that you make in favor of me getting one, if it doesn't work out, I won't hold it against you.
Thanks in advance & have a great weekend.
