I sent a suggestion to Les for the next round of tests that I think
would be pretty awesome, and that is very slow morse. I thought I would
bring it up here to get other folks opinions. Lets say a station sent
out a few 1 kHz tone-generated CW IDs during the DX Tests, say with 2
second-long dots and 6 second-long dashes. Maybe even switch between 1
kHz and 2 kHz tone CW. This would allow DXers, with minimal equipment,
to run their receiver audio through a program such as Spectrum Lab and
actually see the morse code in the waterfall display. Here is a dump
that I took from Spectrum Lab from this mornings KTMI DX Test:

I had my receiver set to 649 kHz, USB mode with 3 kHz bandwidth. You can
plainly see the traces 1 kHz above the carriers on 650 kHz, these are
the CW ID's KTMI ran during the test. These traces were even visible
when I could not audibly hear the morse code. Now imagine if the morse
code was really slow, per my suggestion above. The long dots and dashes
of the "DE KTMI KTMI KTMI" would easily be visible on the waterfall even
if too weak/QRM'd to get by ear.
Seems like this would also do wonders for foreign DXers monitoring these
tests. I really think it is something worth considering that would
provide a lot of 'bang for the buck' for DXers with minimal effort on
either the BTC or the station to implement.
