thing about filters... this is narrow band audio, voice, specifically Male on most streams... filtering too much 'low end' destroys the 'power', depth of the signal, and often results in 'tinny' sound. Some streams are quite 'tinny'. and can actually 'emphasize' the higher noise frequencies ... try to stream flat curve 100/150 HZ - 5000 Hz if possible... your stream will sound much clearer, we think.
the quick build ¼ wave ground plane antenna is very effective for marginal signals,
http://noaaweatherradio.org/howto.html#antOne of the biggest irritants is excessive or low stream volume...
Single biggest irritant is 'one channel only'... especially if volume out of 'range'.
streams go offline, audio stops... Anthony (Fox in the Wind) found a great utility for monitoring,
and we found another.... virtually no performance hit on device, and will send you an email if something fails.
http://noaaweatherradio.org/quality/monitor.htmlMerc lot of streams have some small degree of 'hum',... and as long as it meets the 'ear test' its fine... I checked your stream a few moments ago, and it sounded great.
Sometimes getting completely 'rid' of it is near impossible... My Owenton KY stream has noise, due to strength of signal and my environment... I probably could improve it some more, well, I know I could, but that will take a bit of work and a big 'roundTOit" served on a "Let's Do It Anyway" dish of will power and energy" ... partly because I use it as a reference at times, and partially because I'm just lazy.
