Hi Jim. whist it involves a change in "usage" from our end it would not seem
unreasonable to ensure that the US stations have a chance of hearing us
without nearby swamping. I think this is an interesting development becasuse
it now seems that Frtiz is extending the experiment to intercontinental
tests/qsos.......an activity he discouraged earlier....due to the terms of
the original application and grant I believe. I have to admit my opinions
carry very little weight as a "non-active operator" :-)) But maybe it will
stimulate others with differing opinions to voice them to you.

Best wishes
Alan G3NYK
