Team 1511 has experienced the OI/RC radio issues as well for the past 2 weeks. Same symptoms of cutting in and out for a period of a few seconds, as well as the master disable switch on the competition port NOT killing the robot as it should.

I contacted IFI over this past weekend, and spoke with Corey Chitwood, who was extremely helpful. We had a discussion regarding potential RF interference issues, internal vs. external antennas, and we tried a few of his suggestions. From our discussion on Saturday morning, there is not a mass recall or swarm of teams reporting problems (yet). He mentioned the teams who have posted above this, and said that they found and fixed a clear hardware problem on the very first team to have sent their radio back. At that time, he had not received the other radios that were RMA'd, and couldn't provide any additional info.

We tested extensively on Saturday and Sunday, both in autonomous and manual drive modes, and continued to experience radio cutouts. After nearly squashing a mentors foot with a speedy autonomous (and un-killable) robot, we reverted to last years radios. I obtained a RMA from IFI on Tuesday afternoon, and our modems ship out Thursday morning.

When we receive our new ones I'll post an update regarding their performance.
