[RFI] Here we go again

[qrv at kd4e.com]

Wes,

	As I recall a number of them tested clean when new but
with use, presumably heat-related, their filtering degraded and
the RFI rose.

	Given the preference for politicians and bureaucrats
vs engineers at the FCC it is doubtful that they are doing a
better job today than in the past.

IMHO, YMMV ...
