I propose that "we" start calling it what it is:  Removing the TX inhibitor.  or, if that doesn't suit, making your HF rig into a General Coverage Transceiver.  There are very few, if any, "MARS/CAP" mods that simply unlock the MARS or CAP frequencies.


With almost any modern rig, you are simply disabling the circuitry that activates the TX INHIBIT function of the CPU.
