I think I have the same issue with the transmitter only transmitting with 80. Since I exchanged fmtx with the modified 1.3 I have to have my phone much closer to my car antenna. Any clues as to why this is the case?


Edit:
When I plug in USB to charge the phone, reception by my car radio gets even worse. Shouldn't the modified fmtx transmit with the same power (120) all the time, regardless of USB or headphone connection status?
Btw. I'm using "fmtxd PR1.3" modified by Jacekowski from posting 3 in this thread.
