My theory was newer television tuners seem to be better at recovering from signal drops so since the 1609 was new maybe it would be better also. The 1600 and 2250 tuners give satisfactory results except when it is windy outside; I also have to have the antenna in the storage area (attic) else one piddled-off S.O.!

It is somewhat windy today and the initial testing displayed a rare minor pixelation with the two weakest stations whereas with the other tuners the signal would have probably been highly distorted and possibly unwatchable. What I need is a good storm to really test ? we?ll get one! I can also increase the signal strength by approximately 7 dB by removing a 4-way splitter that was feeding a pair of 1600 tuners and a 2250 tuner in the old Backend.

There seems to be no logic

I’ve an external yagi, powered signal spliier, am 25Km from transmitter.

I’ve used with varing degress of pixelation
Leadtech (usb)
HD homerun quad (network)
Haupauge Nova T (usb)

now using the new Haupauge Win TV (usb) and neary a block or stripe. Same setup. The worst was unwatchable.  
One would expect small differences between tuners not MAJOR ones. I’m now using 2 of these with same results so not a fluke.
