Subject: TS-140S TX All Freq Mod

To enable the TS-140S for transmitting on all bands:

1. Disconnect radio from power supply and antenna
2. Remove top and Bottom covers
3. Locate the control board (I believe it is on the bottom --NOT BEHIND TH
  THE KNOBS LIKE THE 440!!)
4. Cut D31 on the control board
5. Reassemble the radio
6. Reset the radio by holding the A=B switch while powering up the rig.

Disclaimer:  This Modification is for those who need it to operate MARS only.
