'Twas a little switcher that was powering my Oak Hills Research QRP
Wattmeter giving it a convienient path to my attached 1500. It was
s9+20 at 14.015 on my handheld Kenwood thf6.
See the little bugger at:

Thanks for all the ideas and now the bottom end of 20m is useable.

Great radio, Graham.

Richard:
That looks like the signature of a switching powersupply. Are you
using a
"wallwart" or other switching supply
to power your 1500? I would start by changing power supplies.
Cheap switching supplies are notorious for emitting this kind of
garbage.

Does anyone recognise this type of noise?

I figured I'd ask before starting to unplug everything as I have
all sorts
of possibilities in my lab. I still hear it with a dummy load on
the
antenna of my 1500 but not as strong.
