the 2 times i tried, I tried going in via the ant input as it said, after the 2nd try, I found that having the freq generator hooked up had no impact on the voltage level at the point being measured, nor did changing freq slightly.
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,

and find the best working channel
till then, I will use direct input, will try to get a better video tonight.
