There are two versions of the SainSonic AX-05B. The old one has the BNC connector and is the same as the non compliant CZH-05B which has issues. The new revised AX-05B is 100% legally certified for part 15. It has a TNC connector and filters. I even looked up the info and the ONLY difference between the revised SainSonic AX-05B and the Decade CM-10 is the type of antenna and the PRICE!!!. The SainSonic AX-05B has a reversed TNC and rubber duck and the Decade CM-10 has the telescoping antenna. I looked at BOTH transmitters and the circuit boards are identical. If your talking about that other website the transmitter they refer to is the 7 watt one which Amazon is selling inside hey sainsonic AX-05B box. The 7 watt and 5 watt are the AX-5c and AX-7c which according to James of SainSonic is NOT certified legal in the USA. Neither is the AX- 05B with the BNC connector. This Transmitter the SainSonic AX-05B with TNC connector does show up on the FCC website when you enter the numbers on the back of the transmitter. Plus talking to James the Tech Support of sainSonic asured me 100s of times this transmitter is legally certified part 15. Now saying certification for part 15 means nothing? Then how can you say your part 15 certified transmitter doesn’t go over and is illegal? Can you say every person with a Whole House FM transmitter has or is expected to have a field strength meter? Think not. So this brings up two possibilities. 1. The FCC has changed its stance and allows 500 mW Transmitter to be to be certified. Or 2. After the NAB’s crybaby lobbying many manufacturers are only using 10 to 25% of the legal allowance. I sorta believe both. But we will never know. What we do know is that certification should be trusted or we throw all our transmitters in the trash and give up on part 15. I choose to go with certification. The NAB trolls will purposely start start misinformation such as the Whole House fm Transmitter goes only 200 feet. This we know is a blatant lie I’ll take Frankenmuth Michigan and the Christmas Town as an example. I can hear that Transmitter quite clearly one quarter mile. So too they run this Transmitter 24 7. The range of the transmitter matches the 500mW revised sainsonic AX-05B. That in itself tells me I’m using the same exact strength. So I just want to clear up some blatant misinformation from an anti fm website that is clearly stated anyone running an FM transmitter is a pirate. Well if that’s true I guess we have plenty of pirates in America. Now you see it’s all the nonsense. Just like the car that passes inspection and as soon as you go outside the inspection tickets for non-compliance you have something to stand because you had intent on following the rules. That is what matters. I’d say keep your keep your manualsand keep your box. If the FCC had a problem they would have had ample time to pull the certification. But they did not so what does that tell you? Common sense tells me its legal.
