Folks,
I have been working on a semi-realtime band monitor
system, and there are some early results at
www.aa6e.net/aa6e/rfi/monitor.html. I am recording
what happens on 40 & 20 M in 2 kHz channels in my
particular environment.
Why would we want to do this?
-Learn a little about propagation conditions vs solar
activity, etc.
-Pick up (and record) RFI problems
-Get a baseline, pre-BPL deployment
-Too much hardware, software, and time available ;-)
Ed Hare actually suggests it's a bad idea to make
baseline recordings if you want to proceed against the
power companies with a BPL complaint. The logic is
perverse, but he may be right. See Ed's famous URL:
http://www.arrl.org/~ehare/bpl/measurements.html .
But as a frustrated radio astronomer and programmer, I
couldn't resist. Already, I see some interesting
"UFOs", but they're probably somewhere in my house.
The process needs to be automated more, and I will
have to decide if it's worth trying to make a
long-term record (months/years).
How could this stuff be made more useful?
73, Martin, AA6E
