- Hello Everyone-
I just heard about and joined the group- thinking "well, what's the
worse that could happen?" I've been hearing the low hum on an off for-
well it must be years. Unlike the the hums that I have heard of in
the NM, this one doesn't seem to be on all the time. It's
intermittent and I hear it better when there's less background noise,
traffic, planes, etc. I'm in Miami.
