TRANSMITTER OFFSET FREQUENCY
This transceiver allows you to store the frequency,
and offset direction in Memory Channels 0 — 9, and
A —b, or you can select these functions directly from
the keyboard.

The TM-221 A/321 A have been programmed accor­
ding to the standard ARRL Band Plan, regarding
transmitter offsets. Please see the enclosed charts
