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.

Thanks,
