Convert to 12 Meter Band
 
Although this procedure hardly qualifies as a "mod" (too easy), it is certainly useful for the FT One series owner. Conversion to the 12 meter WARC band is as simple as replacing a crystal. The 12 meter xtal is replaced with a 30.52 Mhz 3rd overtone xtal in a HC-25/U holder as specified in the FT 101 series maintenance manual. No other modifications are necessary as the new band is close enough to the original that the current components work. To replace the xtal, remove the up cover and find the xtal board located at right front of the rig.
Xtals marked xxxx are standard while oooo are optional on some units. X5, for the 11m, band is an option and may or may not be installed.
