[RFI] Horrific Ugly Noise Found and stopped...

[Diane & Edward Swynar]

Hi Dave,

Don't hold your breath expecting that the replacement lighting system will
be any better...

...And don't hold your breath expecting any relief from the federal
authorities, either: the pro-China lobby has many well-placed friend$ on
high both here in Canada & the USA. The concerns of a few radio geeks like
us hardly matter to them.
