[NCARC] FOLLOW UP Fw: potential RFI source or defective unit?

[Rod N0RC]

>From reliable authorities (ARRL/FCC):

"...Under the rules, they need to Verify that the device meets the
conducted emissions limits and then put the label on the unit or in
the owners manual.  Verification means that the manufacturer needs to
have the device tested, either by its own staff or by an external lab,
and keep the results on file in case asked by the Commission or its
representative.

Of note, the legal limit for conducted emissions is high enough that
an S9 signal could result to an 80 meter dipole located 100 feet away
from its wiring....."

So it looks like that's the way it is, unless NiteRider chooses to do
something (I did write to them). Until such time, I'll use the charger
at work to top off the batt before riding home. At home I'll use a
very quiet Maha.

Riders: Don't shy away from NiteRider because of this, the light is
very good. Just take note and find a work around for the charger as I
did.
