Tnx for the report.  I was playing about with the settings looking for
suitable sets of frequency span / pixel intervals for Argo, and decided to
leave it going at high power as conditions seemed quiet on the band.

It looks as if Argo on 3s dots is best suited for 20Hz span 0.15s pixel
interval. On the 10s dot setting 5Hz span and 0.7s pixels look about right.
Didn't try any slower modes as I didn't want to spend the whole evening
playing with it !

Haven't implemented the semaphore font yet.
