INSTRUCTIONS ARE ACTUALLY IN THE ADVANCED FEATURES SECTION UNDER THE
HEADINGS SIMPLEX CHANNELS AND DUPLEX CHANNELS.  THE DUPLEX CHANNEL
PROGRAMMING DISCUSSION IS POTENTIALLY CONFUSING.  THE GUIDE SEEMS TO
ASSUME THAT YOULL BE SETTING UP A NONSTANDARD OR POSSIBLY CROSS BAND
DUPLEX FREQUENCY ARRANGEMENT.  AND IT IS IMPORTANT TO NOTE THAT
BAOFENGS DEFINITION OF DUPLEX IS REALLY HALF DUPLEX THE GT 5R CANT
TRANSMIT AT ONE FREQUENCY WHILE SIMULTANEOUSLY RECEIVING PRODUCT
REVIEW BAOFENG GT 5R DUAL BAND HANDHELD TRANSCEIVER REVIEWED BY
STEVE FORD, WB8IMY WB8IMY ARRL.  NET ACCORDING TO BAOFENGS ONLINE
ADVERTISING, THEIR GT 5R TRANSCEIVER DEPARTS FROM ITS PREDECESSORS
IN ONE PARTICULARLY IMPORTANT WAY 100 LEGAL VERSION WITH THE
COMPLIANT TRANSMIT RANGE AND SPURIOUS EMISSION, COMPLIES WITH FCC
EQUIPMENT RULE PART 15B AND PART 90.  BAOFENGS INTRODUCTION OF A
TRANSCEIVER THAT CAN ONLY TRANSMIT ON AMATEUR FREQUENCIES IS A
POSITIVE DEVELOPMENT.  STILL, THERE IS THE MATTER OF SPECTRAL
PURITY.  OVER THE YEARS, THE ARRL LABORATORY HAS REPEATEDLY FOUND A
HIGH PERCENTAGE OF BAOFENG TRANSCEIVERS TESTED BY THE LAB TO BE NON
COMPLIANT WITH FCC EMISSION REQUIREMENTS.  ACCORDING TO BAOFENG,
THIS ISSUE HAS BEEN REMEDIED IN THE GT 5R.  DID THEY SUCCEED?  MORE
ABOUT THAT LATER.  DUAL BANDS, AND MORE THE TINY BAOFENG GT 5R CAN
ALMOST DISAPPEAR IN A SHIRT POCKET, OR WITHIN THE PALM OF YOUR HAND.
DESPITE ITS SIZE, THE GT 5R OFFERS DUAL BAND FUNCTIONALITY AT OUTPUT
POWER LEVELS SPECIFIED AT 1 W OR 4 W SEE TABLE 1 FOR ARRL LAB
MEASUREMENTS.  THE FREQUENCY RANGES INCLUDE 144 TO 148 MHZ, AND 420
TO 450 MHZ, AND AS BAOFENG HAS STATED, THE GT 5R WILL NOT TRANSMIT
OUTSIDE OF THESE RANGES.  IT WILL RECEIVE BETWEEN 136 AND 174 MHZ
AND 400 AND 480 MHZ, BUT IF YOU ENTER A FREQUENCY OUTSIDE THE
AMATEUR BANDS AND PRESS THE PUSH TO TALK BUTTON, NOTHING HAPPENS
OTHER THAN THE SOUND OF THE ERROR BEEP.  THE GT 5R PACKAGE INCLUDES
AN 1,800 MAH LITHIUM ION BATTERY AND A DESKTOP CHARGER SEE FIGURE 1.
AN OPTIONAL 3,800 MAH BATTERY IS AVAILABLE.  ON A FULL CHARGE, THE
BATTERY SEEMED CAPABLE OF POWERING THE RADIO FOR MANY HOURS,
DEPENDING ON HOW MUCH TRANSMITTING IS TAKING PLACE, AND AT WHAT
POWER LEVEL.  THERE IS ALSO A BATTERY SAVING FUNCTION THAT CAN PLACE
THE GT 5R IN ONE OF FOUR SLEEP/WAKE CYCLES.  THE TRANSCEIVER WAKES
UP WHENEVER A SIGNAL IS PRESENT, THOUGH YOU MAY OCCASIONALLY MISS
THE FIRST SECOND OR TWO.  THE LCD SHOWS THE FREQUENCIES FOR THE A
AND B VFOS AS WELL AS BATTERY STATUS.  YOU SWITCH BETWEEN VFOS USING
THE A/B BUTTON.  THE DISPLAY IS SMALL AND MAY PRESENT A CHALLENGE
THOSE WITH VISUAL IMPAIRMENTS.  FORTUNATELY, THE GT 5R HAS A WELL
DESIGNED VOICE ENUNCIATOR THAT WARNS WHEN THE BATTERY IS LOW, IN
ADDITION TO IMPARTING OTHER BITS OF HELPFUL INFORMATION.  IT SPEAKS
IN CLEAR, UNACCENTED ENGLISH AND IS QUITE EASY TO UNDERSTAND.  AUDIO
VOLUME IS CONTROLLED BY THE SIZEABLE KNOB ON THE TOP OF THE CASE,
WHICH ALSO SERVES AS THE POWER ON/OFF SWITCH.  THE GT 5R HAS PLENTY
OF AUDIO PUNCH, BUT IT IS
