let me start from the begining. here is where i started. i started with the idea than when you are on the phone with some you have a created an ELECTRICAL circuit. I have understood this to mean that i can send more than just analog input through the microphone. now if in theory i can send more than just voice thru the phone why couldnt i say for instance take the output from a vcr which keep in mind is a minitur transmitter. so a tap being played is being transmitted thru either channels 3 or 4. now i want to state that what i send is not have anything to do with a PC. no mpg avi etc..... now what i am proposing is that since you only have a bandwidth of 400hz to 3khz then the only way i could transmitt information would be to use a tone from 400hz to 3khz. so if for instance the channel 3 frequency is 44Mhz. to send that signal over a telephone line and then into a tv i would have to modulate the audio tone at mhz. it is known that there is a bandwith 400hz to 3khz. there is nothing that i have seen that says i cant modulate or turn it on and off 44 million times a second is this your understanding too? does this hold water? now i know they have phones that can let you see another person. "but what i want to accomplish is sending the output from a vcr and through the phone line connect it to the input of a tv in another location"
