2. Specifications
All measurements were made using a 14.0 V supply and 50-ohm load
unless otherwise indicated. Values are typical; your results will be
somewhat different. Specifications are subject to change without
notice. (See option manuals for additional specifications.)

2 The K2 can receive well outside the indicated bands, but this extended range
is not specified or guaranteed. Transmit ranges may be limited for export to
some countries. The K2/100 (KPA100 option) limits transmit from 25-27.999
MHz to 10 watts or less.
