Strange Observation

Greetings Everyone,

Last evening (around 0000) UTC),I was walking around the kitchen here
in the apt., and then I stepped outside to check for a MW station ID. I
noticed that every time I got within a few feet of the telephone
connection box out back, I suddenly started getting a huge amount of
increased signal strength and clarity on any MW station. I'm seriously
thinking about trying to tap into this. After all, the box clearly
says "customer access" and is only shut by one little screw. I'll let
you know what I can find out on this as soon as I have the time to mess
with it. Obviously this isn't illegal because there's not a lock nor
seal on the box like there is on our typical electrical meters here. My
main concern is that it may overload the E-100 or the SRF-59. You guys
ever had this experience before?? I don't know for sure, but I might
accidentally be onto something pretty good here. Will try this tomorrow
and get back to you all on it.

*** What's occurring here is that the telephone wiring is serving as an antenna. Placing a portable near it creates an inductive coupling, much the same as if the telephone box were a longwire antenna or a loop.

I would NOT try to connect directly because you'll potentially get noise, unwanted voltage etc. Continuing to use it inductively is reasonable to do however.

Thanks Russ, I'm heeding your advice because you obviously have a
lot more experience in this department than I ever thought of having.
I can adapt to sitting in a rather weird area of the kitchen (just on
the other side of the T-box) better than I could handle screwing up
my radios! I certainly appreciate your feedback on this! 73 to you,
Kirk-

You've got a free passive loop. Enjoy it but don't hook up the wires.
Disaster could happen.
