The second file does seem to be hum free, but mine doesn't seem objectionable...
Listening at work running sound through Monsoon MH-500 speaker system...
I've got no problem trying to improve the sound quality, just a little crunched for time this time of year...
If we could agree on a specific time, I can plug in a portable CD player, and play some music to see if it has the hum, at least that would help narrow down the problem... then people "out there" could listen...
I can also use a battery in the radio for a period of time, although I think it will suck it dry very fast... I am using a cheap "multi" AC adaptor to power the radio, but I've had it plugged into 2 different outlets, and reversed the orientation, apparently to no effect... (uh, is that a bad sign that the AC adaptor doesn't have a polarized plug??
)
I can try listening on my HT system again, this time with both my 10" transmission line subwoofers running, powered by their own 250W amp........
, AND, sit on my couch which has 4 transducers attached, powered by a plate amp.... I'll report back on the hum...
LOL........ just messing around...
ncpilot,
This is really odd. If I reduce the bass on my system, the hum is much less. Maybe your home stereo audio system is somehow filtering out the hum.
Just as a test, here are a couple wav files to play. The first is your stream, the second is another NC stream. Let me know if you hear a difference.
