Ed,
Listening on a TH-D72 on about 137MHz, yes the noise from the P3 is indeed
loud. However, by the time I have more than a metre or so separation

Good morning all
I raised the issue of noise coming from my P3 several months ago.
It is noticeable on 2m, using an EME array that is about 50ft from the
rig. There is a combination of azimuth and elevation in which the array
looks directly at my shack and under those

It seems rather unlikely to be a radiating EM field launched directly
out of the panel cut-out of the P3.
I tend to agree with Ian's advice, and with that you received from
Elecraft. Following up on it -- suitable RF chokes for 2M would be Fair

This morning we had a very good opening on 6 meters to the east coast Maine
down to Florida from the PNW,
When the band died, I thought it would be a good time to go out and snoop
the neighborhood for the line noise source that bugs me, So i got out my

Ed,
Listening on a TH-D72 on about 137MHz, yes the noise from the P3 is indeed
loud. However, by the time I have more than a metre or so separation
between the P3 and the handie, the noise drops below the handie's squelch
threshold, so for me at least, it's a very localised phenomenon.

I am using a K3 with an XV144 to a TE brick, to a 5 el beam at 35

noise level at the K3 listening on 50.100 when the P3 is on vs. off. I
also have an ICOM 910H sitting about 1.25 feet from the P3, and

Sorry, but your test is a test that has NO meaning whatever. Does a
tree falling the forest make a noise if no one is there to hear it?
No, it is considerable meaning. The question was, is the P3 a noise
source? The test I described is a good way to
