[RFI] SO2R and 2nd harmonic

[Kenneth G. Gordon]

Excuse me, but I firmly believe that there is one very important factor involved here which, 
at least so far, no one has mentioned.

And that is the horrendous amount of broad-band noise almost all modern transceivers 
output. The only modern transceiver I know of in which this issue has been addressed 
directly by the designers and dealt with properly is the Elecraft K-2 and its cousins.

A recent study on this issue by, I believe, a German ham, proved conclusively that ALL 
other modern transceivers output a terrible amount of broadband noise, and any "good" 
linear amp will make this problem far worse.

I will attempt to find that study and post a link to it here as soon as I can.

I believe he showed that this noise output significantly raises the noise floor, even far from 
the location of the transmitter itself.

Perhaps this is an important factor in this so-called "RF flooding" issue. At any rate, I 
believe it should be investigated.
