Did anyone get past page 1? Here are all the tests that were performed (p6):
15.203 simply says the detector coils must be unique to the detector. Somewhere there is another rule that says all testing must be done with the largest available coil.
15.205 is a list of keep-out bands, mostly military.
15.207 is for AC plug-in operation. It doesn't apply to the detector but would apply to, say, a battery charger. Likely the charger is tested separately.
15.209 is for the actual detector operation.
15.247 is all Bluetooth.
15.215 is to ensure you don't generate interferers in other particular bands.
Here are the tests done for the Goldbug 2:
Same sort of tests. Usually detectors are also tested for unintentional radiation under 15.109, for example all the digital noise that is generated on the PCB. The Goldbug 2 uses a crystal and some digital circuitry (no micro) so it had to be tested for this:
I'm surprised this does not show up in the Manticore tests but it could be a separate document, as it is for the Goldbug. Or, it could be their test lab interprets the rules differently. Sometimes different labs insist on different rules, kinda like taxes and CPAs.
I don't know why people get all wrapped up in this topic as it's pretty irrelevant. But hopefully this sets the record straight once & for all, or at least until the FCC rewrites the rules.
