I have one for UHF that came w/ the ATI card... But that doesn't help KQED on channel 9... Even KNTV that is the only station in the area that broadcasts their ATSC signal on VHF works perfectly fine w/ a set of rabbit ears layed flat (and pointed twards the tower)...

Now that the tv season has ended, not much need for a third tuner... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
