I'm a little confused on 7.8000 MHz entering the mixer IC5. Especially as it goes thru the coil before it enters the mixer. Reference schematics do not look correct to me. Here is Rick Jackson's re-draw of the Cobra 148GTL. He has the 7.8000 MHz entering IC5 on pins 11 and 13 (where the 34.XXX MHz is entering) and has 34.XXX MHz entering IC5 at pins 7 and 8 where the 7.8000MHz is entering. Either way, I would like to know how that 7.8000 MHz is pushed thru the coil. Is it the AM TX +8v on one side of R191 that pushes the 7.8000 MHz thru the coil into pins 7 and 8? Can someone explain it to me?
