Everyone uses VCR's for the RF modulation on channel 3 or 4!
I can't remember the last time I used a VCR.
Both my 630TS and CTC9 Felton has VHF tuners, and there are no VHF stations in my area. I was honestly going to buy one of those RF modulator boxes, but use my satellite receiver for the time being. Most newer model RCA directv boxes output full feild color bar by pressing the menu and info bottons on the receiver at the same time, and it has RF output too. I'd use my UHF to VHF converter for off air reception, but I guess the only way to use it is if I connect an amplified antenna to it's input since it has no RF amp?
