The model FT-227R is a new synthesized 2 meter FM
transceiver specifically designed to provide high
performance for amateur VHF /FM communications.
The transceiver utilizes the famed Yaesu computer theory,
and is completely solid state. The unit has provision for
the operation of 800 digital Phase Lock Loop channels5" in 5
kHz steps between 144 to 148 MHz. An “optical coupling"
system eliminates rotary switches which always used to get
oxidized and noisy. The digital LED's -display the selected
channel in MHz, 100 kHz, and I kHz. The bright display lets
you easily read the frequency in the bright sunlight without
A memory circuit memorizes any channel out of 800 channels.
A touch of a switch brings you back to the memorized channel
In addition to a conventional ⅛600 kHz repeater split, any
transmitter offset frequency is memorized with a touch of a
push-button for ope ration on any ODD split frequency repeater.
The tone burst generator is built in for tone burst accessed
repeater operation, and is fully adjustable for pitch,
duration and level.
An optional tone guarded squelch (TGS) is provided for a
silent monitoring. Placed in the TGS mode, a tone guarded
signal automatically opens the receiver squelch circuit. The
tone frequency can be selected within 160 Hz to 250 Hz.
The BUSY lamp lights up if the channel is occupied by
another station when the tone guarded squelch is in use.
This also works as an alarm when the receiver volume is
accidentally set too low.
