Any electric gurus out there willing to help?

Ever since re-doing the wiring in my DG-300 last year, I get
intermittent loud static on my radio. *It seems to be connected to
whether or not I have ship's power going to my EW MicroRecorder. *The
odd thing is that I followed the Becker wiring instructions and made
sure to use a shielded wire for the connection from the Becker to the
remote speaker/PCB assembly. *I would love ideas on how to help stop
this! *Details below - any thoughts, see anything obvious that I'm
failing to do?

I've a Becker panel radio. *Last year it suddenly became unusable due
to loud intermittent "static" noise. *I finally tried turning the
squelch screw on the side of the case, you may have to remove your
radio to get at it. *That fixed it. *Have no idea what changed. *Has
worked flawlessly ever since.

That may make the symptom go away but the risks now is not being able
to hear weak radio transmissions.
The extra concern here was you described it as a "loud noise". If its
something that is breaking squelch with a large signal turning up
squelch to silence this is a bad idea.

If this suddenly started happening it could be something as simple as
a wire behind the panel moved closer to another, a poor connector or
break developing in a coaxial cable (cable flexed differently than
previously), etc. It it may be worth trying to diagnose the root
cause. Start with identifying what device is causing the periodic
interference. Start by turning down the squelch so that you get fairly
often occurring interference then poke around to make that better/
worse.
