Hi Ben, I think we're in total agreement. The way the FCC rules are written, there is always a baseline set of rules, with specific additional authorizations granted by rule. Section 15.709 grants radio emission permissions under very specific conditions. Anything not mentioned in section 15.709 is an implicit fallback to the baseline set of rules.
Section 15.109 of the rules specifically covers non-transmitting devices, and according to the FCC, non-transmitting devices are limited to a power of 0.000000012 Watts in the UHF band (which is the same as 0.000012 mW, or -49.2 dBm, or 200 uV/M @ 3 meters). This IS the FCC's definition of "off"; they had to pick a value, and this is it. Any channel not specifically granted an "on" power level in section 15.709 would implicitly be "off". The laws in most jurisdictions are defined this way, where all the rules are "additive". Anything not mentioned in a specific add-on rule would implicitly fall back to the more general rules underneath. I'm fine with there being an implicit "off" whenever there is not an explicit "on" contained within a message. Whether the DB communicates the "off" parameters to the device is separate matter. Best regards, Andy
