What you say would be correct, except unfortunately my testing
overnight, which I have just checked this morning indicates that UIDIGI
doesn't actually do as the doc's say. The settings I made per the
manual should have caused the no via posit to issue every 10 minutes,
and it did. The WIDE1-1 to issue each hour, and it did, but the
WIDE2-2, which should have issued once/hour with a 30 minute offset
actually issued every 1.5 hours with a 30 minute offset! So it's
implemented wrong, but maybe I can make it work to my advantage
somehow. However I will contact the author about this....

Ill go with identical beacon text, I prefer that anyway.

Ill contact Marco IW3FQG about implementing your suggested standard.
You may want to join the UIDIGI yahoo group, perhaps in web read only
mode to cut down on your e-mail, so you can follow this request to
Marco. You might want to chime in as well. Ill e-mail you an invite
directly just in case.
