Hi Lucky,

They would be talking about the AC level across 222 ohms; there wouldn't
be any DC there. If you do have any questions for me, it would be fine to
e-mail me directly.
There are quite a few knowledgeable folks on the NG, so it is good to
include all of them with these kinds of questions.

Hi there Pete

I was looking at the specs of the 150, and I see the audio output specs
for
the headphones jack is 4v 220ohms. Does the headphone jack put out 4v
DC??
I'd like to harness it for it's 4v of power. What woud be the best way
to to
this and have one hot and one ground?

You're completely misreading the specifications.

They are talking about 4V AC, measured across 220 ohms. That's the level
of
the audio coming out of there.

And newsgroups are for eveyone. If you are looking for an answer from
someone specific, and I think that's actually rude, then use email.
Hence there's no reason to address posts to someone specific.

Since the headphone jack is mono, where would the 4v be hot? On the very
tip
of the headphone plug?

If I stuck a mini stereo plug in the larger mono plug and plugged it in,
would one of the resulting wires coming out of the cut mini plug power
out
at 4v DC? What could I use for the ground {-} line? Surely it's not the
other mini plug wire? Just use the radio's case for ground?

Thanks one that sees thru radios

Hi Pete

I wasn't sure if I should e-mail you directly since you never gave me
permission to do so. Yes, I should of just posed it as an open question for
everyone to answer. I wanted run a LED off the power from the radio.

Right now I'm using a 3v w/wart PSU for a 5v super bright blue LED. In fact,
I don't need a resistor for it. Works just great but I was looking to make
it more compact and eliminate the PSU. I really don't want to go inside the
receiver to tap a line for it. But I might in the future.

Thanks
Lucky
