I have this problem in my station. I run three simultaneous stations
for RMS Pactor, RMS Winmor and ALE. I don't have a enough land to put
three antennas more than a wavelength apart, at least not at 80m. So I
put one active receiving antenna as far away as possible and use a power
divider to the
Thanks! Now I understand.

Drax,
It is not incoming conducted emissions that they are worried about, but the
local oscillator being radiated out of the receiver. Any heterodyne
receiver has a local oscillator located relatively close in the processing
chain to the antenna. If the receiver is not properly designed, then th
Should have read tune for the LO's to be less dated!

requirement in the FLEX-5000 with direct conversion, we need the preamp

What legal requirement is there [in Europe] to have a receiver above 28MHz
to be above a certain sensitivity level?

There is no downside of having the preamp on 6m.

"Warning External Preamp is required above 28Mhz to maintain CE compliance."
Since I'm not required to maintain CE compliance in the USA what is the
downside to using the preamp on six meters?
What is the "CE" trying to protect?
