You guys crack me up!!! Here you are arguing over whether or not these guys are using amateur radio and NO ONE has bothered to check to see if any of these guys are hams so I will do your homework for you:
TIV Team:
Sean Casey - Name does not appear in FCC database
Ronald P. Nagle - There is one KC2LHD in Brooklyn, NY. This could be the one in the show, but if this guy is a die-hard storm chaser, why would he live in NYC?
Byron Turk - Name does not appear in FCC database
Dominator Team:
Reed Timmer - Name does not appear in FCC database
Joel Taylor - There is a Joel Taylor in WA, CA and SC so one of these could be him.
Chris Chittick - Name does not appear in FCC database
Vortex2 Team:
Josh Wurman - Name does not appear in FCC database
Herb Stein - Name does not appear in FCC database
Scout Team:
Danny Cheresnick - Name does not appear in FCC database
Aaron Rupert - Name does not appear in FCC database
TIV Doghouse:
Brandon Ivey - Name does not appear in FCC database
Matt Hughes - There is a Matthew Hughes in VA, WI, TX and KY so one of these could be him.
Team Twistex:
Tim Samaras - There is a WJØG in Lakeland, CO
Carl Young - There is a Carl Young in NV, TX, FL, CA, TN, WI and MT so one of these could be him.
Tony Laubach - There is a KWØLFF also in Lakeland, CO so it is very possible that this is our guy.
So given that fact that most of the guys on the show definitely do not have amateur radio licenses and the fact that a handful of them had name matches but with no actual proof that they are the guys on the show, it is highly unlikely that they are using amateur radio - CASE CLOSED!
