And how about setting up a separate e-mail address for such reports? I'm thinking that would encourage people to report bad sigs, and would serve notice to deliberate violators that a report is just a few keystrokes away. N1MM Logger makes it very easy to annotate a log with such reports, whether or not you work the offender.

I'm planning to do some SDR recordings in the next significant phone contest and see what emerges.

Randy,

How about adding a something in the LCR reports if you received an excessive bandwidth report or you received 3 reports. That way the station, if they are looking at the LCR's would have a heads up that hey someone said my signal was lousy at XXXXX time and maybe they would look into it......

I think we all know "excessive bandwidth" when we hear it. I.e., you can hear the splatter or clicks for many Khz before you tune on to the signal.

The CQ WW DX Contest issued a number of warnings for poor signal quality for the 2014 contest. We had the first disqualification for poor signal quality
to a station on CW.

The CQ WW Committee is not omnipotent. We don't spend hours tuning through the SDR recordings looking for bad signals. We rely on the participants to report signals that were causing problems on the band (with call sign, time,
frequency, and details).  We do follow up on all of these reports.

Not everything reported is objectionable enough to warrant any action. But, it is important that the contest community speak up about signal quality - not only to the sponsors but to the offenders as well. High power and wide signals are one of the biggest threats to our enjoyment and to recruitment
of new contesters into our ranks.

We would be delighted to receive serious proposals for a technical standard around signal quality. It should be something easily measured using an SDR recording. Until then, we will continue our function of serving as referees
that call them like we see them.

Will be interesting to see where in the results these filthy signals I
recorded end up.
I suggest that all this talk about excessive bandwidth will remain just
so much hot air until and unless contest sponsors define what they mean
by "excessive bandwidth" - with parameters such as maximum width at, say,
40db down for both CW and SSB.

CQWW was the first major contest to introduce an "excessive bandwidth"
rule, backed up (as claimed) by a worldwide network of SDRs and digital
recorders
- three years ago or so.  However, the rules make no attempt to define
excessive bandwidth, and I'm not aware of any penalties having been
imposed for this reason alone.  If I'm wrong, I'd be happy to be
corrected.
