MODIFICATION INSTRUCTIONS FOR THE ALINCO 110T/E,112T/E/EM,410T/E
 
A VERY SIMPLE MODIFICATION CAN BE DONE TO THE ALINCO 110T AND ITS SISTER
RADIOS WHICH WILL OPEN ITS TRANSMIT/RECEIVE TO 130-170 MHz, AND RECEIVE
ONLY TO 330-350 MHz AND 870-890 MHz. THE LATTER TWO BANDS ARE THE
MILITARY AIR AND CELLULAR TELEPHONE FREQUENCIES, RESPECTIVELY. THE FORMER
IS THE RANGE THROUGHOUT THE POLICE, FIRE, SPECIAL EMERGENCY, MARS, HAM
(2 METERS), PAGERS, MARINE, ETCETERA, OF WHICH THE ALINCO WILL TRANSMIT
AND RECEIVE (MAKE SURE SWR IS LOW ENOUGH TO TRANSMIT ON THE DESIRED
FREQUENCY).
 
THE MODIFICATION IS DONE BY A SIMPLE CLIPPING OF ONE WIRE WITHIN THE
RADIO. THIS WIRE IS YELLOW AND LOCATED DIRECTLY ABOVE THE VFO TUNING KNOB
ON THE TOP SIDE OF THE RADIO INTERIOR. SIMPLY REMOVE THE TOP COVER AND
LOCATE THE YELLOW WIRE, FORMED IN A LOOP, IN THE FRONT LEFT TOP SECTION.
CLIP THIS WIRE AND SEPARATE THE TWO ENDS. REPLACE THE TOP COVER (DUH!).
 
IN ORDER TO ACTIVATE THE MODIFICATION YOU MUST RESET THE ROM CHIP WITH THE
FOLLOWING PROCEDURE.
 
1:PRESS AND HOLD THE F KEY AND THE VFO/M KEY AT THE SAME TIME, AND TURN
OFF THE POWER SWITCH. NOW TURN THE POWER SWITCH ON AGAIN, WHILE STILL
HOLDING THE BUTTONS DEPRESSED.
2:RELEASE THE BUTTONS--FACTORY PROGRAMMING IS NOW IN PLACE.
 
IN ORDER TO SWITCH FROM BAND TO BAND, DEPRESS THE FMW KEY. ONCE IN THE
DESIRED BAND YOU CAN SLIDE TO THE DESIRED FREQUENCY RANGE QUICKLY BY
DEPRESSING THE MHz SWITCH TO FIRST TUNE THE FIRST THREE DIGITS TO THE
FREQUENCY RANGE, THEN DEPRESS THE SAME SWITCH TO FINE TUNE TO THE
DESIRED FREQUENCY. EXAMPLE--TUNE FROM 145.05 TO 155.45... DEPRESS THE
MHz (IN THE VFO MODE) AND TUNE THE FIRST THREE DIGITS TO 155, THEN
DEPRESS THE MHz SWITCH AGAIN AND FINE TUNE TO 155.450 MHz.
 
TO DATE, I HAVE NOT FOUND A SIMPLER MODIFICATION IN ANY HAM RADIO. I
AM STILL LOOKING FOR MODIFICATION PLANS FOR THE KENWOOD TS-700SP ALL-
MODE 2 METER BASE STATION SO THAT I MAY GO BELOW 144 MHz TO RECEIVE
WEATHER SATELLITE TRANSMISSIONS. SO IF YOU HAVE SUCH MODS, PLEASE ADVISE.
 
I APPRECIATE ALL COMMENTS AND SUGGESTIONS TO THE ABOVE TEXT. REMEMBER
THAT WHILE SCANNING POLICE AND EMERGENCY FREQUENCIES NOT TO KEY THE
MICROPHONE. IF YOU ARE MARITIME MOBILE, YOU MAY WORK THE MARINE BANDS
ON THIS RIG WITHOUT ADDITIONAL LICENSING. IF YOU ARE AUTHORIZED TO USE
OTHER FREQUENCIES, THIS CAN BE DONE AS WELL WITHOUT ADDITIONAL PERMISSION
FROM THE F.C.C.
