I'm a ham radio operator so most of my effects would be skewed to that so most likely I'd bring along things like a shortwave radio and handheld police scanner, perhaps a small laptop and a BeoFeng VHF/UHF HT. I have a Grundig G6 shortwave radio that goes from longwave to 30 Mc and can tune in SSB and that is the size of cigarettes. Who knows but I guess I'd be speding my spare and rec time tuning is AM stations from the KFS and so forth.
