Dan,

Thank You! Eliminating the terk power supply did the trick. I was even impressed to discovered that when the Sony DSS receiver is turned off, it is still sending DC current to the terk, keeping it active for the TV tuners in the house. It took a little experimenting, but now I've got both OTA from the terk and DSS coming in thru one cable to the bedroom. In the attic, I split off one leg of the terk thru a DC block into a 4way splitter. The splitter then sends OTA signals to four cable jacks scattered thruout the house.

Technology is wonderful... when it works!

Thanks again, Dan.

Dave
