COBRA 2000 GTL AM carrier issue

Ok. I have output from that Cobra 2000 GTL now but I am still missing my 7.800MHz input to pins 7 and 8 of the mixer (IC5). I have the 7.800MHz coming out of the crystal filter up to one side of R63. After R63 I don't have it. I know they say a picture is like a thousand words...so here you go. These are the voltage measurements I made along with the frequency counter probe measurements. Oh where oh where is my 7.800MHz lol...IMG_4592.JPG
