ZollyMonsta: Congratulations.. you also likely have now broken the Terms and Conditions of your contract.
SteveC: Good points all - thanks for the warnings. I find it a strange irony that we have this cable technology, first designed in the 1950s (???) to deliver TV signal, which has evloved to extent that it is dangerous to plug a TV into it!
Two questions - for anyone who might know offhand:
* Why do TelstraClear broadcast unscrambled content on the cable, if there is no ligit reason for people to need it?
* The cable from my house goes to to a dangly thing hanging between power poles that, I think, converts it to digital signal on the fibre part of their network. Presumably that limits the potential for RF interference?
Humm ... the insatiably curious might learn more by reading this paper: http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?tp=&arnumber=729851&isnumber=15750
Be warned that if you do cause issues you will be found (there are people who monitor the network for spurious noise).
