Multiple participants in the 2024 CQ WPX CW contest that occurred on 25 and
26 May 2024 were impacted by deliberate QRM (DQRM). The CQ WPX Contest
Committee has collected observations on the DQRM and concludes that the
source of the DQRM is a single operator using multiple remotely controlled
stations located in the USA.
The following is a partial list of DQRM incidents. We are asking that
remotely controlled station owners review their activity logs to see if
their stations were active around the times and frequencies shown below. If
so, it is probable that their stations were used by the DQRM source
operator, and we request that the remotely controlled station owners take
appropriate actions to block future access by the DQRM source operator.
