I found a modification you can make to extend the transmit frequency range for the Yaesu FT990 and FT1000.
Mods for FT990-1000
-
Remove top and bottom covers.
-
Remove the top screw on each side that holds the front panel to the chassis.
-
Pivot front panel down slowly.
CAUTION: if you let it go, it will flop down rapidly and probably tear something loose. Behind the meter will be the CNTL unit. It has a metal cover of about 4 * 8 inches.
-
Snap the cover off. Look to the top of the unit. You will see JP-3.
-
Remove the solder connection on JP-3.
Modification is now complete.
***Note: I haven’t tried or verified this, proceed at your own risk.
A reminder – do not transmit outside of legal bands!
