UncleYoda Posted Sunday at 06:06 PM Report Posted Sunday at 06:06 PM 1 hour ago, SteveShannon said: Are there any regulations regarding distribution and sale? I don’t know of any. If I’m correct, that would mean an addition of regulations. A person should never request more regulation. Yes. All the regs that refer to what is required for certification (bandwidth, deviation etc). (Assuming of course that no radio nuts are building their own GMRS radios.) Although it's the manufacturer that controls that, vendors have to sell radios that meet U.S. requirements. Enforcement against Baofeng radios targeted vendors or importers. Our responsibility is to just use certified radios and not modify them in a way that breaks the rules so we don't negate the certification . Quote

Please provide specific citations about distribution and sales. Certainly regulations prohibit operating non-certified transmitters for GMRS, but I see nothing in part 95 about distribution and sales. I might have missed it. Quote

But anyway, this is the most obvious and other sections supply details about specific requirements: § 95.391 Manufacturing, importation, and sales of non-certified equipment prohibited. No person shall manufacture, import, sell, or offer for sale non-certified equipment for the Personal Radio Services except as provided for in §§ 2.803(c)(2)(i) and 2.1204(a)(11) of this chapter. See § 302(b) of the Communications Act (47 U.S.C. 302a(b)). See also part 2, subpart I (§ 2.801 et seq.) of this chapter for rules governing marketing of radiofrequency devices; part 2, subpart K (§ 2.1201 et seq.) of this chapter for rules governing import conditions. [86 FR 52100, Sept. 20, 2021] And besides what in the regs, it's how FCC chooses to enforce some things. They did go after a vendor in Texas and I think an importer in California over the UV5R and similar radios, probably back around 2017 give or take. It even affected BTWR; they stopped selling them, then started back briefly and quit again for other reasons. Quote

Rugged Radio got a NoNo letter from the FCC for selling 6 different radios that RR advertised as being compliant and were not. Even with such gross disregard and massive exposure, they still did not get a fine. I don't know how bad you have mess up before the FCC gives a damn about GMRS violations, but the bar is obviously very high. WRTC928, SteveShannon and WRUU653 3 Quote

That's why I don't get worked up over anyone using a ham radio on GMRS. If they keep to appropriate power and bandwidth, I don't care what radio they're using. I'm not the radio police, and if FCC doesn't consider it worth enforcing, neither do I. (TBH, I don't get worked up over someone in the mountains of Montana using 5 watts and wide bandwidth on FRS 10 either. They're not going to interfere with anyone else.

Before I could get worked up about it, I'd have to be able to hear it Except for the people a mile or so away using their 0.5 watt FRS radios that’s getting hammered by your 5 watts. You can’t hear them, but they’re very likely can hear you. Does that still make it OK? You didn’t hear it. Given equal radio receiver sensitivity then range can be limited by the square root of the ratios of the transmitter powers. So 5 watts verses 0.5 watts could result in a range increase of 3.16 to 1 in favor of the 5 watt radio. SteveShannon and WRXB215 2 Quote

I have said many times that I think it's important to be considerate. I said I don't consider it my job to enforce things that don't affect me. My point was that someone using 5 watts in the middle of a 12,000 acre ranch in Montana isn't going to interfere with someone else. SteveShannon and WRUU653 2 Quote

I few years ago I tested my Yaesu FT3D and my BF-F8HP with an SA. On frequency, there were no side spurs on the BTech, but there was a pretty decent size spur on the bottom of the signal on the Yaesu. However, there were zero harmonic spurs on the FT3D compare to something like 15 spurs plus/minus the carrier frequency of the BF-F8HP. And several of the close harmonic spurs were at power levels close to the same as the intended carrier frequency. Like, within 5 or 6 dB. Quote

When i get back from camping I'm gonna check it on the Tiny Spectrum. My experience with some of the Baofeng's I've test is hilarious with with their harmonics. I've seen second and thirds just about equal to main carrier. My Hytera's are pretty clean. The DM 32 sounds good, I'm getting good reports with it.. I like the radio marcspaz and Lscott 2 Quote
