	The comments were a bit mixed weren't they. I wasn't too sure what to 
make of the devices themselves since discussion kind of degenerated into 
some people complaining about who knows what and who doesn't. There was 
little discussion of the devices.

	Impressive frequency range. That sounds like it goes from LW almost to 
cordless telephone frequencies. Some people were complaining about it 
being 8bits though. They were saying 12bits was supposed to be a 
significant difference. Still for an entry level piece of hardware...

	Any opinions on the other ones you mentioned? For me, I'd be looking at 
about $20.00 tops...

	I caught something somewhere which said because of the original article 
all but one of the suppliers were sold out.

	As I recall there were a couple of members of the Seniors Radio Club 
who are members of the MUUG. If they are no longer on the list, I know a 
couple of people.

	Like I said a couple of months ago, Don pointed me to a site on the net 
were I got the plans for a "Coat Hanger" digital TV antenna (just a 
regular UHF antenna). I could bring it to a meeting if anyone wanted to 
give it a try. I'm also looking at making a Rev0 Gray Hoverman antenna 
as soon as I can come up with the parts (just for comparison). 
Apparently this is better than the "Coat Hanger" antenna (and a lot more 
work). If it's done in time I could bring it in too. BTW, they are up to 
Rev2 now.
