Let's get with the times online and on the swap and no longer call it the MARS/CAP/60 Meter mod.
Let's call it what it is! "TX Inhibitor Removed" is one suggestion.
There are no modern rigs of which I am aware that have a specific modification for MARS, CAP or 60 meters. Most times, a zero-ohm 'resistor' is removed from one of the traces near the CPU.
Even on most older rigs, a discreet wire or diode is clipped, disabling the TX Inhibit function.
