Subject: PTT MOD FOR FT-411
HELLO, A FEW DAYS AGO I WAS USING MY FRIEND'S YASEU FT-411 AND FOUND OUT THIS
NEAT TRICK!!! FIRST, A LITTLE BACKGROUND... AS I'M SURE SOME OF YOU KNOW, YASEU
CAME OUT WITH THE POPULAR 411 A FEW YEARS AGO. JUST RECENTLY, THEY CAME OUT WITH
AN "ENHANCED" MODEL, THE 411-E. THE ONLY FOUND DIFFERENCE IS THE FREQUENCY LOCK
OF THE RADIO. THE 411E HAS A FEATURE THAT LETS YOU LOCK THE PTT AS WELL AS THE
FREQUENCY.
TO ACTIVATE PTT LOCK ON THE 411:
--TURN RADIO OFF
--PUSH THE 6 BUTTON, HOLD IT AND TURN ON THE RIG WHILE YOUR STILL HOLDING IT.
--NOW, PRESS FM 6, YOU SHOULD SEE "L".
--PRESS FM 6 AGAIN, YOU SHOULD SEE "PTT"(BOTH L AND PTT WILL APPEAR IN THE
BOTTEM LEFT CORNER OF THE LCD DISPLAY.
***CONGRADULATIONS*** YOU HAVE INSTALLED PTT LOCK IN UR RIG. TO TURN IT OFF,
JUST REPEAT THOSE STEPS.
