hi to all
Please comment on the overall plan pd detector with feritte antenaa.Based on bfo detector If sending signal by Ferrite antenna At the point where the metal is rapidly changing due to the sensitive nature of the ferrite core frequency This change in frequency can be based on the type of bfo metal detector was processed. Please give your opinion on this issue ![]() |

hi wm6
Do you have a schematic for this area.(For the transmitter antenna ferrite).please give. Such a system can be remotely discriminate between ferrous and non ferrous metals.Ferrous metals are low frequency ferrite core and And non-ferrous ferrite antenna frequencies high. ![]() ![]() Please comment G.L |

BFO distinguish between metals as on your scope pics is possible only in near EM field (direct target impact on the TX coil/tank) and not in remote RF field too.
