i did not however try as Kevin mentioned, tapping it in on point E, if I do try again, I will most likely go that route, but as mentioned, my contacts for chan 7 are most likely damaged, and to make things work I have to go with a mod I can pic the chan output on to get the most clean pic,, 3-4 DID work, but had a lot of RFI, most likely all the computers i have
so hopefully once I can get the IF setup ( mostly the 1st IF and traps ) i can use a modulator like this,https://www.amazon.com/fosa-Modulato...07G9ZYXW9?th=1
and find the best working channel
till then, I will use direct input, will try to get a better video tonight.
Speaking of computers generating RFI... everytime you bring in another modern signal processing device you'll more than likely be dealing with yet another switch mode power supply and micro controller generating even more RFI. Something to think about.
