well, we found the problem mostly
one of the CSA's at Milwaukee(Pete Thomas) a 706 past mentor handed us a new 5.5x2.1 barrel jack for the radio power and that fixed the issue until the last match of seeding matches. Had NO issues from the time we put in that jack to that last seeding match. Then it started happening again and we lost comms 2 times in the elimination matches. an explanation for that has not been found.
Our VRM is under(on the opposite side of a piece of aluminum sheet) and about a foot to 18 inches away from the radio. Cannot tell you how frustrating this season has been. Absolutely no comm issues on our practice bot for the 3 weeks we were able to use that then comp bot lets us down. Wired by the same meticulous student using all new parts. FYI the barrel jacks that we initially used were(on the comp bot the one in the KOP) and on the practice bot the one from AM with the screw terminals. Both caused radio reboot issues. we also swapped out the comp bot VRM with the well tested practice bot VRM.
Suppose we will just have to go with POE as we did for the last half of the Milwaukee regional. When we had the comm issues in the elimination matches we had dual power to the radio. The new barrel jack and POE.
Still had comm losses. grrrrrr
