Must be getting close to a dollar by now....

I found that the AGC correction should only be applied to scrambled (suppressed/inverted sync) signals so a hardware approach needed to discrimate this as it seemed to degrade normal signals IE differences in brightness & general quality as well as only operating if the code had locked to the signal. My decoder quite happily locks to normal signals and the result is at least an inverted colour burst when it's not needed. The parts list kept growing so I used the SX as a big bag of reconfigurable hardware - the 'virtual' circuit. The Jerrold arrangement controls it using info from the data packet.
