$10 is probably about the average cost of a build in sound cards in the average computer and they work just fine. I've run into more issues with the higher end build in cards and having to disable all the crazy DSP options. I had one install that upon receiving MT63 it would only get about the first 30 characters and you'd see the waterfall signature rapidly dim.
It wound up that there was a noise reduction setting I had to uncheck by accessing the sound card icon in control panel. The card thought MT63 was unwanted noise and just decided to automatically lower the level until it heard no more! -Dave, KB3FXI --- In digitalradio@yahoogroups.com, "John Becker, WØJAB" <w0...@...> wrote: > > Jeremy > > Maybe the fact that it was 10 bucks may have something to > do with it. > > > > > At 02:24 PM 6/5/2010, you wrote: > >Hello, > > > >When purchasing a new radio this last week I decided to also set my > >computer up how it should have been long ago.
