I was a WRTC 2014 volunteer responsible for overseeing 4 different stations.
Of the 8 radios at these stations, 6 were K3s. Before the contest started,
we did have a significant issue with phase noise interference from one of
the K3s on 15M when that station was beaming toward the adjacent

If we reduced the K3 output to 30 watts, there was no problem. Fortunately,

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.

The West Valley Amateur Radio Association operating as K6EI and

CW, SSB and digital HF stations. We used K3s and KX3s
exclusively. Our antennas were arranged in a line to minimize
interference. We would often have CW, digital, and

I think that most are looking for something the K3 WRTC numbers are
not telling. I rather doubt that people went out and bought them for
the WRTC. With those kinds of numbers, the market had already made
its decision a long time ago.
I know some who borrowed K3 and/or P3 for the contest. That

Thank you. I’ve done this by eyeball for pairs of rigs, but this really helps.
It is a huge chunk of work to compile this.

Thank you for the graphs.
This is something the North Carolina PVRC group that did field day
together north of Raleigh already knew about K3's vs. the world from a
pile of experiences. We had five or six K3's available to us, and we
went purely with the K3's on HF in the 3A class. We had a
There were 1-2 Yaesu radios that did not have the after-market key click mod
and were causing tremendous unnecessary QRM to other WRTC stations. Those
radios were detected in the Friday setup period and swapped out to eliminate
the QRM.

I'm partial to the comments below. While I prefer Win-Test for CW (and SSB)
contesting, I strongly prefer WriteLog for RTTY contesting. N1MM Logger is
a close second for RTTY. At the same time, I have to acknowledge that the
current SO HP World Record holder in the CQ WW RTTY Contest used

Thank you. Very persuading comparison.
Could you possibly add some modern SDR based rigs to the comparison?
Hello Igor,
So far, I've not bothered to look at the older ones, having read this
work, and ARRL has not reviewed anything since the Flex
Hi Jim - will you be adding the spectral display graphs of transmitter
composite noise testing which appear in the various product reviews to
your summary?
If so, I will help mine the graphs from the reviews, if that will ease
some of the work load. I know that takes serious time.
I agree completely. The rig and logging software have very to do with the
outcome.
The #1 team probably has a sore back and sore arms, from lugging 7800s there

A little number crunching of the results (because that sort of thing appeals to me...

WE can rationalize this any way we like, but the fact is, 5 of the 6

I think that the rig is not very important. One tidbit to support this

I think you're correct Dave. Unlike all other contests, WRTC is
refereed and everyone uses identical antennas and power ... about as

Fred,
Not really. It would very much effect those individual stations in the
respective close area 'group' of the offending transmitter. And there were
three of four fairly large 'groups' of stations.
The other groups and the more widely spread stations would not be affected

IMHO the most of those participants who had to travel long way have chosen
the lightest out of the best radios. And K3 is unbeatable in that respect.
Unfortunately in WRTC2014, locations were much different and very often
that was the most important factor affecting the final standing.

P.S. In case others missed it there was a major firmware update (MCU 4.86

That's more lopsided (2/3 K3's) than the first WRTC after the K3 came
out (1/2 K3's).

P.S.
It appears the official report of transceivers and software is here:
http://www.wrtc2014.org/radios-and-software-used/
The K3 was used by more than four times as many competitors than rigs
from any other manufacturer (Elecraft: 75, Yaesu: 16, Icom: 15,
Kenwood: 8, Ten-Tec: 2).

Yeah, it all depends on how you look at it. Back in the 2010 WRTC it

as strong as this year.

However, the fact that a very large percentage of these top operators
