Hi Kurt,

You said "We already have specific emissions values, I just suggest
lower.", but I don't believe there are radiated emission limits below 30
MHz, just conducted emission limits below 30 MHz in the US.  If you
introduce radiated emission limits in the FCC rules for frequencies below
30 MHz then you do in fact risk overriding the protection we have with the
current "harmful interference" stipulation.

On the other hand maybe you're talking about reducing the "conducted
emissions" limits for frequencies below 30 MHz which would not necessarily
put the "harmful interference" stipulation in jeopardy.

Hopefully someone better educated on the current FCC rules will step in and
correct me if I've misspoken.

Just FYI,
Don (wd8dsb)
