Gentlemen, 	

As the owner of the HCI domain at:	

http://www.w9wze.org	

I sometimes stretch the boat anchor laws of selectivity and get broad banded.
That is, we don't restrict the Hallicrafters Collectors International
forsale-swap area 'exclusively' to Hallicrafters devotees. You might consider
posting your want on the site.
