Others have posted VG info already, won't add to that. I do know a couple "professional" storm chasers, they both have LMR licenses for their pursuits. Mostly so they can encrypt their radio traffic, so as to not have other chasers, especially those who take groups out to show off storms, their info.
An oldie but a goodie. That one's been hammered to death by the Hams, both Happy and Sad over the last couple of years. Yeah, with EchoLink or DMR/C4FM, etc., et al, I can talk thousands of miles on my handheld. But I prefer the old school nothing between me and the other guy than the ether...
E-1 pay in 74 was 397 per. ETS'd as an SP4 at the 505 per month. For those that care, my MOS was 98G2LAEK3/05H2LAEK3. But was also put on Temp as a 95B when I was guarding the SCIF as there weren't enough MP's with clearances to do the gig.
ARRL has log books. I have a mini one for the occasional portable no cell service ops. Never have I ever logged a GMRS or CBRS contact, but the fields in a log book can be modified to suit any radio service I would think.
