Default RE: Spectra Module

True, the FCC regulations only apply to the USA.

Just amazingly stupid isn't it... The rules that is...
Like it would work any differently in a Futaba than a Hitec...
The governing bodies in this country are truly amazing... they'll regulate and rule
the hell out of something that makes NO difference, and something of utmost importance
gets overlooked... Sorry, just a quick little VENT!!

The issue is that is may NOT work the same in a Futaba vs. Hitec. Typically, the deviation (how "wide" the signal is, with regard to adjacent channel interference) is determined by the amplitude of the signal going into the transmitter, or the module in this case. As such, there is no guarantee that the signal level is the same into the module from a Futaba vs. a Hitec transmitter will be the same. This is part of what type acceptance by the FCC is about. If acceptance is sought, then a given configuration (radio set and module) are tested together to ensure that the levels ARE compatible. Also, due to type acceptance, a mfg. cannot change levels and such in a given radio without having to resubmit it for acceptance, so if it gets certified once, it is extremely unlikely that anything will change. Having said this, I am not saying that Hitec and Futaba are necessarily different in signal levels, just not formally tested, and POTENTIALLY
different, and as such the FCC rules take exception. Either Futaba or Hitec could submit for the appropriate certification on this at will, but then "Not invented by me" attitues and such start to come into play, and we, as consumers, inevitably lose.
