I got really brave and decided to test the SainSonic AX-05B on Low power as well as High. I wanted to bust the myth that the revised SainSonic AX-05B (With reverse threaded TNC connector) would be above part 15 (even at low power). I can tell you from my Own experience not by word of any anonymous experimenter this time around. OK lets get going with the results of the test. I switched the transmitter to Low power by Unplugging it and holding Power and plugging in the power cord to the jack. The Blue back lit display let up and said Hi. I pressed the low arrow and hit power to enter the data. Then it shows the high frequency 107.9 I pressed power to enter the confirmation. Then the low frequency 88.1 I click power again to enter data. Transmitter blinks and turns off with the word off in the display and the blue back light off. Now I turned the transmitter back on and set the frequency to 96.3 Mhz and started my journey to the great outdoors to see what happens. Before I even got that far as soon ans I left my room I heard fading. I walked down the hall to the next room and already the signal was getting weak. I decided to try and go the other way to my front porch and I had to put my hand on the tip of the antenna to pull in the signal. Down the steps I went already the signal was almost gone. Walked down the sidewalk to the driveway which is between my house and the neighbors and the signal was almost unusable at that point I had to hold my hand on the tip of the antenna to even listen. This is far less signal than the Whole House FM Transmitter 3.0 so your not gonna have any helicopters or FCC trucks trying to track you down here at this level. Its laughable at best a little better than the Belkin, but a whole lot worse than the C.Crane and Whole House FM Transmitter 3.0 at the low level. Now for the brave part. I then followed the same steps and switched to High power. The difference was great. I could walk around outside and go around 750-800 feet on my boom box and on a super car Radio in an SUV I was able to transmit 0.06 miles (less than 1/4 mile according to the GPS). So at High power it looks like it matches the Whole House FM Transmitter 3.0 at part 15 level on the SainSonic AX-05B's High power output. Still not 500mW no where near it. So there you go folks myth busted and anyone who has a newly revised version of the SainSonic AX-05B (With reversed threaded TNC connector) can feel good about the transmitter not causing helicopters to land on your roof or an FCC van to park in your driveway followed by police cars and a swat team saying "Hands up and hand over that FM Transmitter NOW!!" I'm sure you've heard all of this crap from HB but unless you have tested this transmitter like I did I don't know where they have got their information. If SainSonic is guilty of in this case is lying about the 500mW output which I think for some reason they never changed that on the manual or the website. But the transmitter's manual says for low power -48dbm which is about 15.8 nano watts. The Whole House FM Transmitter 3.0 from what I've read puts out 18 nano watts on part 15 setting. And BOTH transmitters come with a Rubber Duck Antenna. Its interesting to note too the Decade CM-10 at part 15 level puts out more than the SainSonic AX-05B on Low Power.
