I took some time recently, based on a GRM article about the SRC helmet microphone kit (http://grassrootsmotorsports.com/articles/wiring-up-an-in-helmet-radio/) to wire up my helmet.
Part of the reason I did it is for HPDEs where I may start instructing. However, it appears that Chatterbox has done everyone a favor and re-designed the connector on the Tandem Pro Duo... to yet another nonstandard connector.
According to the gent I spoke to at Chatterbox, it uses a "standard" 3.5mm connector, but it uses non-standard spacing.
I can't seem to find any pictures of the connector, and I'm not about to order a unit only to have to return it if I can't figure it out. Does anyone have one of the new Tandem Pro Duo units and:
1) Have you used any other mic/earphones with it? 2) Could you measure/photograph the new connector?
Thanks!
