Lost bike to bike comms

[The Heff]

Hi all

I have an Autocom Pro 7 Sport which is connected to a Kenwood TK3201 and a Garmin 660. Been using it without issue for some time but recently I have been losing my bike to bike comms. The Autocom becomes live when the side lights come on. On start up I can talk, but after a short time I can only hear my mates but not talk to them. Music works fine from the 660

It's not the headset as I have a headset in another helmet, same problem.

I've checked the push to talk button, all seems fine there. The red light comes on, on the 3201 when the button is pressed, so all seems good there too.

I've changed the extension leads between the unit and helmet, no change.

Checked and cleaned all the cable join points with electrical spray cleaner, no change.

No visible cuts or breaks in any cables

So, could there be an internal intermittent fault in the Kenwood, or is there something I can do to test?

Any help would be appreciated

Have you tried swapping out the radio ?.

Had a similar prob last year . The culprit was the PTT red button , it had worn and wasn't quite connecting to the switch on the inside , so opened up the casing , put a small peice of foil between the two ...hey presto ! Did this on the advice of Sam at chainspeed ( autocom God ). He then sent me a new red PTT button .

Hope you get sorted
