Thank you for bringing to the attention of the contesting community the
existence of contest operation interfering with ongoing emergency
communications. I'm sure we will all be more vigilant to avoid this sort of
thing in the future.
It does not sound like the interference in this case was willful. It is most
likely that the contest operator simply did not hear the net communications at
all. The incidental interference is regrettable.

As a US operator, the frequency of 14.122.50 is clearly in the CW / DATA
portion of the bands for us. It is by no means the "phone" portion of the band.
In fact, during CW or RTTY contests, this frequency is very likely to be used,
particularly when 20m is very crowded.
No doubt you may have chosen this frequency to avoid the US phone operations
from 14150 kHz and higher. If you have taken steps to avoid being in the
primary "phone" portion of the band, it doesn't seem proper that you complain
about other operators using non-phone modes in that portion of the band.

Technically, I would disagree with you. He was clearly not in the "phone"
portion of the band, although I don't believe Germany makes a distinction of
phone subbands.

Not at all clear that he could hear you. Your signal could be drowned out by
other stations he could hear that you cannot.

In CW contesting, virtually no one uses computer CW decoding software.

The problem with your suggestion is there is no clear CW sub-band defined
worldwide. By the US definition of the band, the frequency in question is
clearly restricted to CW and DATA communications. Those definitions may be
different in Canada and Germany.
I agree that the incident is regrettable,
