These are the cleanest transmitters I have seen.

Subject: Re: [RFI] SO2R and 2nd harmonic
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.
