OPERATION
1. Turn the power switch on.
2. When switching to 144 MHz band (or 440 MHz band)
transmitting mode, the power amplifier of this unit will
operate and a high power signal is sent out through the
antenna. Re-confirm the SWR and power at this time by
checking a SWR or power meter. Also, the band
switching of the transmission amp is automatically
operated by detecting the transmitting signal frequency
of the transceiver.
3. During 144 MHz band/440 MHz band crossband full
duplex operation, there may be some minor interference
such as noise trouble in some reception frequency spots
depending on the combination of TX/RX frequencies.
Select TX/RX frequencies that show no interference or
trouble. Especially in the 144 MHz band transmission
and 440 MHz band reception, select frequencies that are
not mutually harmonic.
