Here is what I know.
From looking at logs and reported observations from the FTA's they see the radio rebooting. Immediately after they see the radio return they see the RIO so the belief is that the RADIO is the only think rebooting as the RIO takes longer than the radio and would not show up immediately after the radio if it was also booting.
Even so. The initial thought, before we found out the above, as that we had loos battery connections. We went over all our batteries and did find some that were marginal so we tightened ALL our battery connections regardless if they were loose or not. This did not solve the problem. The problem could not be duplicated in the pit no matter what we wiggled and banged on. We build a practice bot and had no issues with that all preseason. We had the radio from that along so we swapped it in and no joy with that either.
We pulled and re-seated all the wires in the weidmuller connectors on the PDP and VRM and tug tested. Again, no joy. By this time we were past our second match of elims and got subbed out. Not a problem, I would have done the same thing.
Before we bagged we replaced the radio power cable with the one we used on our practice bot and replaced the VRM with a brand new out of the box new one.
Have not had a chance to test since.
Does anybody have any idea what else we should try if this does not work?
Thanks

we had this issue at wpi 2 weeks ago, in all of our qualification matches except for two we lost communication we changed and checked everything, fortunately we were alliance captains, and going into our final quals match we simply decided to move the radio to a different spot and didn't have an issue with it after that something so simply cause suck grief .
