I know the US version doesn't have a TV receiver video output (AM video carrier demodulator is disabled). Non-US versions output the TV tuner's demodulated video signal from an RCA connector. I'm aware of these facts, as they are mentioned in the manual for the device. However I haven't really been able to find out WHY it's disabled in the US version, only that it IS disabled in the US version. No documentation from ICom says why it is disabled in the US version, only that it is disabled in the US version. I have found one or two other sites that claim it's due to FCC regulations, but these I don't count as official sources. And none of these 3rd party sources of this info have actually stated which regulation it would violate, nor any link to an FCC webpage. While there are multiple FCC restrictions on radio transmitters, the only FCC restrictions that exist for receivers is that they must not receive cellphone bands, and they must not decrypt any encrypted government/military communications.
My hunch (if it actually has anything to do with the FCC) is that it has something to do with confusion over the 2009 switch from NTSC (analog TV) to ATSC (digital TV). The FCC now requires new TV transmitters to be digital, not analog. My guess is that since ICom is a Japanese company, the legal experts that ICom hired, might not be as familiar as they should be with the English language, and when reading the FCC's requirement that no new TV TRANSMITTER could be analog, they may have misinterpreted it to mean that all TV DEVICES (both transmitter and receiver) must be digital. But since their equipment design was already complete (all the circuits had been layed out and the device was ready to be manufacturered), they couldn't just change up the circuits and put an ATSC tuner in it (not that they needed to anyway), as the design was already programmed into the assembly-line robots and the manufacturing process was already underway. So they did what they could and re-programmed the one robot that was to connect the tuner circuits, to make it not connect the tuner for the US release, and just sold all the others that had working tuners to all non-US countries.
Well that's what I'm guessing at least. Does anybody on these forums have any idea about the actual reason? And how close is my guess to the actual reason?
