Isn't there an ITU standard for callsigns?
AFAIK the Australian Foundation call complies with that standard.
Hi Onno,
where I say non-standard I mean within the constraints of the digital
source encoding used by the various modes in the WSJT suite of software.
That does not exactly align with all callsigns issued around the World,
to do so would greatly impact the efficiency, and hence the sensitivity,
of the various weak signal modes. In general the WSJT suite of
applications define a standard callsign format which is described in
their documentation (e.g.
https://physics.princeton.edu/pulsar/k1jt/wsjtx-doc/wsjtx-main-2.1.2.html#PROTOCOLS
paragraph 3), with some extensions to allow use of some other valid
callsigns by restricting message content or using hash codes to replace
callsigns in certain message formats.
