Is the Acom 1200S frequency expandable? mars mod?

Can the Acom 1200S transmit frequencies be expanded? mars mod? I see the 600S is expandable by removing 2 diodes...

Found it!!! Same mod as the 600S. Remove diodes 202 and 203 on the cpu board. You can find it and pics on DX engineering web site. Works just fine.

Good morning Bob. How goes the ACOM 1200S after mod? Still working good? I need to mod mine for MARS ops.
