With the motorcycle helmet headset not working as it should be with the Midland 42 I had an idea that might work to solve the problem.
Firstly would be to place a loopback plug into the PTT button connector on the wiring for the helmet headset and waterproof this with Sugru.
Next, create a new adaptor using a 2.5mm plug for the radio and a 2.5mm socket for the existing plug on the headset connector cable, this adaptor would contain a new connection point for the handlebar PTT, all the wire joins will be sealed with heatshrink tubing to keep them as water tight as possible.
Once the above adaptor is made, test this with both the Midland and Intek to ensure compatibility, then further test to see if it can be left in situ for use with PMR446 radios, it should be the case that it can be, if not this modification is designed to be removed easily, as Sugru is simply silicone it should remove as easily as silicone sealant.
This will be done this coming weekend, in the mean time I will be testing the CB's audio quality using the earpieces, I can listen to the CB gateway for this.
