OK, so that exlains why I was able to get the NES to come in so well at the wrong channel (CH. 9 rather than CH. 3.)

It looks like what I need to do is set my converter box and RF Modulator to channel 3 hook them up to the TV antenna input and then fiddle with the local oscillator adjustments for channel 3 until it shows a proper image on the screen and then adjust the fine tuning knob (UHF Tuner Knob) and go from there.

I think other than the channel selector confusion I think we can call the Bugeye TV as good as fixed!
