Perhaps this is discussed somewhere in the thread, but I am surprised by the
lack of Flex SDRs in the mix. I would have thought at least a few would be
there for PR, if no other reason.
PR? What's that?
The K3 and KX3 are both SDRs with knobs. I'm guessing that you mean SDRs
without knobs.
My interest is primarily contesting, the subject was radios for
contesting, and rigs like the Flex products have made little headway in
the contesting community. I know of only two guys contesting with Flex
radios . One is K6TU, and the other is K6XN, who bought K6TU's older SDR
that is new model replaced. No, I don't remember which models were
involved.
However, several guys asked, so I've added all three SDRs that ARRL has
tested to the plots. I've also corrected a labeling error on one of the
plots, added a plot of phase noise for a 500 Hz bandwidth, and added
some text. It's all still at k9yc.com/TXNoise.pdf I suspect that these
plots will make it clear why contesters aren't thrilled with these radios.
By all means, before you consider one of the Flex radios, be sure to
study this work by Leif Asbrink, SM5BSZ.
