Becker AR4201 Radio Transmission Problem
Today, after curing a ground problem with the antenna end connector, we were able to transmit on frequencies from 127 to 136. So we know the wiring is ok, but the radio won't transmit from 118 to just below 127. According to another case, the radio is not at fault and the solution is to upgrade the cable and re-crimp. So this will be the next step.
Any suggestions are welcome. RMM

Becker AR4201 Radio Transmission Problem
Late this afternoon, we substituted with another antenna that is proven to be fully working. The same condition resulted. Below 127, the radio opens the transmission channel (the PTT click is audible and the radio displays a black triangle indicating transmission) but carries no voice. Above 127, transmission is fine. This leaves the radio as the place with a faulty part. Will call Becker first thing on Monday morning.
