To get TV1 to run UHF, you need a 6.3 UHF/IR remote. Remove the blue tab. Inside you will see a sliding switch, slide that to the middle. Go to System Info screen on the box and press record on your remote. You should see the remote address for TV1 switch to UHF/IR and whatever code you have set.
Now, when you go to put the chip back in, it is going to slide the chip over, undoing what you just did. However, if you shave the fat side of the chip with an exacto-knife or a utility knife, you can get the chip to slide in without switching the dipswitch inside. An easier way is to buy the correct UHF remote key that has the green #1 and a black stripe.
