[QUOTE="mbasko, post: 584581, member: 4485"] Pretty sure the spread spectrum transmitter quoted in the FCC licensing will be relating to the 2.4GHZ WIFI band of the Minelab protocol transmitter or possibly Bluetooth too? (like the Equinox). Bluetooth uses frequency-hopping spread spectrum (FHSS) & other WIFI protocols use direct-sequence spread spectrum (DSSS) i.e. cordless phones, home wifi etc. For other audio protocols like Minelab's own proprietary system it's likely FHSS to reduce interference. As an example the above quoted frequency range is 78 channels (2402.0 to 2480.0MHZ). Bluetooth is usually 79 channels I think. FCC Rule Parts 15C [/QUOTE]
