Have had the 340/Pegasus set up for about a month now.
Biggest "con": no DSP noise reduction option!!
The Omni VI+ has a beautiful NR function, particularly
for CW, but nothing on the 340. Where I live, there is
essentially no "man made" RF noise to worry about, but
we are also a loooong way from any DX (Hawaii is the most
isolated QTH on the planet, nothing closer than a few
thousand miles). So, DX is often weak, lots of F layer
hops to get here, but bounces off the ocean help, hi.
Anyway, I wish for my Omni NR button back! Now, would
a Timewave 599zx substitute?? The 340 AGC, is wide open
on a dead band, and the audio noise output is very high.
Connecting to the dummy load, still a lot of noise out.
The 340 meter reads at the noise floor, - 135 dBm or so,
but the IF and audio gain bring it up loud.
The Timewave specs specify the DSP noise reduction is
about 20 dB. If I turn down the "RF" gain of the 340 20 dB,
I don't see a really noticeable noise reduction, but this might
not be the same thing. Don't know what the NR reduction
in the Omni VI+ using their algorithm might be; ARRL did
not test it in the 1997 review, nor is their any info in their
"expanded" test report about the DSP NR in the Omni.
So, is it a good idea to buy a Timewave to mate to the
