Hi James,

I was hoping you could clarify your findings... Are you saying that the
1609 tuners are working better, or worse than the other tuners?

I am confused because  you say there was neary a block or stripe, but then
you say the worst was unwatchable....

I currently am using the Haup. 2255 tuners, but am thinking of upgrading to
the 1609 if it's really better, which a previous email on the list seemed
to indicate.

Thanks!

George
