CONVENIENT: As the transceiver has 10 satellite
memory channels, once set, desired satellite fre-
quencies can be recalled instantly.
NOTE: As the downlink (MAIN band) signal is ap-
plied to the SUB band unit in-circuitry in satellite
mode, an optional FL-133 c w n a r r o w f i lt e r is nec-
essary to operate CW-N mode.
