[CQ-Contest] Band Change Violation

[Walter J. Legowski]

The sponsors are apparently still using the same flawed log-checking 
software that they were using many years ago.  The software is unable to 
attribute which transmitter is running and which is mult-hunting, so you 
have to tell it (via the Cabrillo file) which transmitter is which.  In 
your case, with only one transmitter, this could be problematic.

We also received no response when we emailed the sponsors many years 
ago, and they apparently haven't fixed an error that was called to their 
attention way back then, by us and others.  Their "band-aid" fix is to 
require that transmitter 1 and transmitter 2 be identified in the 
Cabrillo file, rather than fixing the algorithm in the software.  We 
don't know how this could work with only one transmitter, and maybe in 
your case, it didn't.
