I'm wondering if anybody out here has built/knows details about remote extensions using the AC home wiring. For eg, I have seen ads for devices that can serve as an extension for the phone. The base unit of this device plugs into the phone outlet. Then an extension unit plugs into any 110 V AC outlet and lets you plug your phone into it, effectively letting you plug your phone into any power outlet. I suppose that the base unit uses the 60 HZ Power line as a carrier, and modulates ( FM /AM ?) the phone signal. The remote unit then acts as a demodulator. Doe anybody have any comments/ experience/ circuits/ sources /info for such a device ? /sundeep #############################***********************############################## <sundeep@caere.com> Caere corporation "me worry ? who ? me !!? why do you ask Dr Freud ?
