OTA NTSC Picture Quality
Although my only roundy is a non-functional 21CT55 and I didn't watch the Rose Parade in SD or HD I still feel compelled to comment on this year's Rose Parade screen shots. The OTA screen shots on Bob's thread so far have been mostly taken from premium CTs which conform perfectively with NTSC WB IQ standards. These roundys were undoubtedly driven at their antenna terminals with quality ATSC to NTSC converters. It seems a shame the "pure restoration dictate" precludes chassis modifications which permit direct external composite video inputs at ther first video amp inputs. How many forum members are using ext-video to evaluate their CT's ability to properly demodulate composite video and process it to the CRT without the degradation of marginal RF tuner and limited bandwidth IF amplifiers?
My CTC2B chassis is not constrained by the "restoration" consideration and has never processed the deceased NTSC RF/IF programmed inputs. It has always performed as a pure composite video monitor, driven from DVD, Laser Disk, S-video VCR, C-Band Big-Dish and 4DTV Digicypher. At the time of its flyback meltdown, I was in the process of modifying it to accept Component Video which should extended its baseband luminance and chrominance to a full 5mhz or 400 lines vs the 3.3mhz or 264 lines of NTSC Composite Video. Now if only I can get a replacement flyback that would converge as good as my original CTC2B, I can proceed.
