the colorburst crystal surprises me, though. Is the colorburst crystal higher accuracy than a standard cheap 8mhz or whatever? The only thing I know of colorburst crystals from is that they are popular in 80m homemade CW rigs for obvious reasons.
I always figured that they were used as they were about the chepest crystals around. Every NTSC TV set needed one so they were made in the Zillions. Don't know if the Digital TV sets use anything like them.
look at http://www.futurlec.com/ICCrystalsMain.shtml and the TV ones are 30 cents while the rest are 75 cents.
Actually as they were working against a reference at 15725 Khz repetition, they probably did not need to be too accurate.
