[Elecraft] LEDs and RFI

[Dauer, Edward]

Many thanks to all who replied to my query about RFI and LEDs.  Very
helpful, as the group on this reflector always is.


I have just one final note, regarding the calculation of energy savings.
There is one variable missing in some of the posts on that subject.  I
think it is not economically rational to calculate aggregate returns on an
investment over a life expectancy greater than one¹s own.  On the one hand
that philosophy is sort of liberating; on the other; I am no longer laying
down vintage port.

Enough OT.  Thanks again for all the replies.

Ted, KN1CBR
