I don't understand the issue. If the people operating the remote station give their location as the location of that station then what's the problem? Propagation doesn't care where the operator is sitting. Neither does the ability of the operator to work a station.
That said, of course if the operator using that remote station uses their home call (i.e. me using N4XD while actually operating a remote station in EU) would be completely wrong and, I believe, illegal. And certainly,in a contest, unacceptable. If I were the sponsor of the contest I'd ban those operators for 3 to 5 years from entering my contest and make it public why. Its not possible for them to claim to have made a "mistake". It would have been done knowingly. Ron N4XD _________________ Topband Reflector Archives - http://www.contesting.com/_topband
