I bought this to use as an In Ear Monitoring system. The plan was to plug it into my vocal effects pedal that sits on the floor and plug a pair of earphones into an FM radio. This did not work because the signal too weak to travel the 5 feet to my radio. I I had read about this issue and thought I could fix it with a mod as can be found on youTube. This was not so as the circuit board has been redesigned.
The other problem problem is that it turns off if no input is received for a short while. As I don't sing on every song, this was also a big problem.
The transmitter barely worked from the day I got it & got worse as time went on no matter what stations I tried to set it at . I bought one of these a few years ago & it worked fine , I emailed the department I bought it off & they didn’t want to help me out . So I don’t recommend the product & I don’t recommend Valuetech
