If this post ends up double I'm sorry I am visually impaired and didn't see my reply to an older post talking about the CZH-05B which that one didn't have 75uS pe emphasis. I tried to reply to:
I have seen the SainSonic AX-05B's image of the circuit board compared to the Decade CM-10 which costs twice as much. If the SainSonic too is certified part 15 as well as the Decade then I suppose that means that the SainSonic AX-05B is not a dirty transmitter that causes harmonic spurs am I Correct in that assumption? if correct then here is the thing. I did ask SainSonic by phone if they sell theirs with 75 uS pre emphasis and they told me that their transmitter uses 75uS pre emphasis instead of 50uS.
My setup is gonna be like this for my Album Rock (Progressive Rock, Deep Tracks), Classic Rock station http://thelegacy.shorturl.com which with the software NextKast which has a nice Audio processor with it that compaires with Breakaway Broadcast along side Radio automation. It has a prevision for a FM Transmitter which does allow for the second USB sound card to receive the same audio that I'll use for the Internet stream encoder. I'll pipe this into the transmitter using the 3.5 mm audio cable. All in all I hope this will work for me as I also looked at the Whole House FM Transmitter 3.0 but I think that one is made cheap. What is your teke? I know it might go a little past part 15 without the Attenuation as posted when ever anyone talks about this transmitter but again reports say it only went 61 meters on low power (Sometimes even high). Something to consider on youtube a man was advertising the Whole House FM transmitter 3.0 on the 50 yard line at MSU football field received on a analog Radio (Not Digital) so with a Digital Radio that range will double if not triple on something like a Rotel, Yamaha, Sony Elite. Part 15 can be useful just wish we could get field strength meters for more accurate detection.
