Another scooter CB progress report

Having fitted the earpieces and mic to my motorcycle helmet, I plugged the headset into the supplied cable wired for the radio and found a small problem.

With the cable disconnected from the headset, the PTT functions normally, that is press to TX, release to RX, however, connect the headset to the radio, all is changed, the Midland 42 goes into TX with no power, and pressing the PTT applies the power, this does not occur on my Intek MT-5050, which is a PMR446 set, and running mic-only with the Midland 42 does not eliminate the issue.

The headset is getting a trial run today to see how it handles an actual trip on the road, I may connect the Midland 42, possibly speaker-only, and monitor traffic on the CB gateway channel.

I also intend to connect up the car adaptor temporarily in order to ascertain if the TX issue is eliminated with the earthing of the scooter, if so, then I won't need to modify the headset in any way, otherwise I'll need to modify it as such so that a second switch is needed in order to transmit.

I will report back later

Due to past abuse and the ongoing issues that left me little choice to reduce time on twitter and IRC I have taken the decision to keep comments disabled indefinitely, apologies for this
