YAESU FT-980
EXPANDED RF
THIS MODIFICATION IS VERY EASY TO PREFORM, HOWEVER DO NOT FORCE THE RADIO APART
!!!!!!!!!!
DO NOT PINCH ANY WIRES WHEN TAKING IT APART, DO NOT TURN ANY OF THE POTS ON THE
LEFT SIDE OF THE RADIO.
PLEASE, PLEASE USE A VERY SMALL SOLDERING IRON SO YOU DON'T RUIN YOUR VERY NICE
RADIO !!!!!!!
HERE GOES:
1) Remove the power from the radio.
2) Remove top and bottom covers.
THE NEXT STEP IS DONE TEMPORARILY.
3) Locate jumper location JW3001 (solder pads) on the display unit and solder
bridge the pads.
DON'T USE TOO MUCH HEAT
The jumper is on the left side of the display board next to the left most CPU as
looking from the back to the front with the radio in the normal up-right
position.
4) Reconnect the power.
5) Press and hold [PROC], [AGC-F], [IPO], & [ATT] and turn the power on.
6) You will now see 02 off
7) Rotate the main dial until the display shows ( 02 - on )
8) Press [PROC]. This will confirm and write the data to the EEPROM memory.
9) Turn the power off and disconnect the power cord.
10) Remove the solder jumper that you made in step 3 above.
11) Replace the covers.
AND AGAIN BE CAREFULL THAT YOU DO NOT PINCH ANY WIRES AND DO NOT FORCE IT
TOGETHER.
I HAVE TRIED THIS MOD AND IT WORKS !!!!!!!!!
BUT AS USUAL DO NOT XMIT OUT OF BAND OR THE RF POLICE WILL COME AND GET YOU
!!!!!!
