A look at some storm chasing vehicles presented this question. Some folks have so many radios packed into their tiny car's it's ridiculous. Now as gas prices are soaring, chasers are going to smaller and smaller cars. So what's the usual equipment? I'm talking about legitimate chasers, not folks that just see bad weather and take off after it, but researches/professional photographers/videoographers. I would imagine in a highly stressful weather situation, that fifteen radios blaring about would be even more disorienting. Obviously a ham radio, maybe a scanner for public safety, some weather monitoring equipment etc.
