An annual ham radio festival that includes a flea market, prizes, and seminars.

A (usually annual) gathering of old, stinky, unwashed, and severely overweight men (with a limited number of women, usually of the same qualities) where antiquated and largely useless radio equipment is bought, sold, and traded, usually at exorbitantly high prices.

While some hamfests are useful for finding odd parts and rare equipment, many have degraded in quality over the years and are not worth going to any more.
