Thanks for the feedback gents. I would have thought seeing that CHCJ is relatively close both distance and directionally to CHCH which is 110% rock solid that I wouldn't have any issues with CHCJ. Could be I have a null in my antenna reception pattern, or some other anomaly causing this. I doubt my changing the PCB baluns on the DB4e's external 300/75 ohms type is the cuplrit (as they helped with most other channels). I will also not re-aim to get CHCJ better at the expense of Buffalo. Maybe adding a dipole to catch CKCO consistently may be an option for reliable CTV coverage. My CM7777 is the old style with seperate VHF/UHF inputs. If I can get my new (Kijiji buy) RCA TVPRAMP12E (see post #4406 in the Signal Amp/Preamp Thread) working I can try out the overload theory.
