Just to clarify, you grounded the "matchbox" part? And it didn't clear
up the noise? If so then that might be the best you can do. I would
focus on noise from some appliance in your house.

Yeah, I don't have the matchbox mounted yet, but I've grounded it to
all sorts of places, and no change.


It's still best to ground the "matchbox". It may not help much in
receive, but may make a difference getting your signal out during
transmit. And it -will- stabilize your SWR.


You're a genius tho,


Many here will disagree.


I solved my "powerline" noise problem at home! I
isolated the problem to a compact fluorescent lamp. Turn it off, S0,
turn it on, S3. My truck is 40 feet from the light too!!!! Have to
chuck this thing in the garbage.

As close to the fuel pump as possible. Just throw down a tarp. It's
worth the effort. You could also try using coax for the power line
from your battery (and grounding the shield), but that doesn't always
work.

Powerline for the fuel pump or the radio? That's a good idea for the
fuel pump, never thought about it. Radio... I question whether or not
the noise is coming from the radios power source.


If the noise is coming through the radio's power line then a cap from
positive to ground, as close to the radio (or 'matchbox') as possible,
should reduce the noise. Otherwise, the fuel pump is creating RFI and
transmitting it on -its- power line, and is being picked up by your
radio. In that case you need to cap the fuel pump -at- the fuel pump.
I would do both..... but that's me.

I never thought about running coax for the fuel line -- sounds like a
good idea. I'll have to try that sometime.


I worked at a radio shop in Albany in the late '80's and drove through
Portland on occasion when they were building all those highways......
gawd what a mess!!! One time it took me two hours to drive just two
miles! I hope it's improved since then.....

Doesn't take 2 hours to drive 2 miles, but it can. Usually an hour for
20 minutes... They designed the interchanges stupider than crap,


.....no kidding....


and so
those eat up 50%+ of your time at near idle speeds.


Yeah, I never could figure out if they were designing that freeway
system from plans or if they were just using 'the force'. Eventually I
learned how to sneak around the quagmire via Sandy. I remember
Portland used to have a Heathkit store..... what ever happened to
that?
