Recently purchased this one and is actually an updated version of the Waio....in fact Waio and Broadcast Vision are the same company. Larger than it looks in pictures and plastic case yes but very durable. A bit more expensive but like the Decades is professional grade and made to last with very good sound quality. Comes with 5 year warranty.
This is FCC and IC certified with numbers on label. Works very well and range is like the Decade MS-100 and the Wholehouse 3.
Has indicators for low signal, input at correct levels and overmodulating...like the Ramsey that Carl built.
Has on board compression/limiting that actually works and is hard to cause distortion....still use with my compressor though and nicely gets to the volume of other stations. Stereo separation is great, listening in car.
These transmitters are sold for fitness centers etc
Only drawback is no on-off switch....on-off is plugging in adaptor plug but I could install a on-off switch and wire it in and mount to outside but I don't know what this will do to warranty so I will leave for now.
Get humming with the adaptor that they send so I just use my own and perfect.
Half the price of the MS-100 new and in my opinion just as good.
