Greetings:
I wouldn't think this (above) would make me "_extremely_ lucky", just
*VERY*
cautious! I NEVER connected the 50ohm 10b2 into the 75ohm CATV network!
Both
"networks" are self-contained, or atleast the PC network is ;)
Based on your observation, YES combining both networks should not work at
all!
A friend of mine told me one of infamous "school-of-hard-knocks"
war-stories
about doing this exact same thing... Aaa-ack!
Sorry, I did not clarify this better!
