It's about as big as a book, but a popular choice is the Yaesu FT-817ND and its replacement FT-818ND. Both are low-powered radios, transmitting only a few watts, but they cover all of the ham high-frequency bands, as well as the popular 2-meter and 440 MHz VHF bands. You can also receive aviation traffic and the FM broadcast band. If you don't need all-band coverage, there are smaller, lighter transceivers available.
