You lose out so much on the bandwidth that the tape costs would be exorbitant. FM trades performance across a noisy channel for bandwidth of the encoded signal. Audio-quality FM is wideband. Narrow-band FM is occasionally used in comms, but is just as susceptible as AM to noise (TANSTAAFL). The encoded bandwidth is something like 2B + D where B= encoding signal bandwidth and D= deviation Jeremy -- Jeremy Harris jgh@root.co.uk
