I'd first give a little TLC to my HAM group's mobile radio tower and then move on building the perfect HAM Go Box. I've had my eyes on the Commander 7200. An awesome grab-and-go.
That's not all!
I'd get an EX4000S Honda Generator and covert it to go old propane and a backup solar panel kit to charge a battery bank array.
Of course, 10k is a lot of coin, so I'd need to get creative. Perhaps outfit my cars with the perfect radios and antennas setup. I'd let the community decide that for me via an online survey, because that would feel like a surprise gift and of course more fun.
If any cheese was left, I'd pay off a few bills and buy my wife a step-up for her Jeep.
