OK. I have done my homework and here's what I have found. It took some time to find the appropriate code sections, but I have experience searching through CFR's related to my laser hobby. I didn't mind doing it since, as previously posted, I am working on my amatuer license, so I took this as a learning exercise.
In a nutshell, I can do what I plan to do with this module without the need of any further certifications or licenses beyond that which the module already has. At least as far as the FCC is concerned.
It needs to be noted that the regulations I found are the same regulations that permit us to buy and use existing
2.4 Ghz radios such as those made by Spektrum and Futaba. Only one regulation I mention below is specific to making the radio yourself.
The AMA may have its own requirements, but since I do not currently fly at AMA fields* or AMA sanctioned events, it's a non issue. Should that change and I desire to use a DIY radio I would of course consult the appropriate AMA authorities in advance.
(*)I have access to a large private field with permission to fly there.
The RF module in question operates in the 2.4 Ghz band and is compliant with part 15 of FCC regulations as a class B digital device and has been issued an FCC ID. This ID is issued by the FCC upon verification of the devices compliance with FCC regulations. I verified the the validity of this ID # through the FCC website.
The manufacturer specifications state that the device works on 2.400 to 2.4835* Ghz at 100 mW of power, using frequency hopping spread spectrum across 16 discrete channels.
47CFR2.106 allocates this frequency band for amateur use under the rules of part 97.
47CFR97.215 allows the use of amateur frequencies for the control of model craft limited to 1 watt of power.
47CFR18.301 defines this frequency band for ISM use (industrial, scientific, medical).
47CFR18.203 describes the requirements necessary for a device to be granted this designation by the FCC.
47CFR part 15 governs devices which may be operated without a license.
47CFR15.247 permits and describes the use of spread spectrum frequency hopping on these frequencies.
47CFR15.23 states that authorization is not required for home built devices for personal use that are not marketed or made from a kit, although they are still subject to the rules under 47CFR15.5 dealing with interference.
(*) The online documentation actually states 2.400-2.485. I have informed the manufacturer of their typographical error. I verified the frequency range with 47CFR2.106 and checked the FCC statement in the manual of my existing
2.4 Ghz radio which states 2.400-2.4835.
