[amsat-bb] RIT for FT-726R?

I realise this radio is getting quite dated, but it's what I have. :)

One of the biggest obstacles to me for working the SSB birds is that the FT-726R doesn't have a proper RIT function. Instead the thing has a "Clarifier" which is active during both transmit and receive, and disables the tuning knob. So, I was wondering if anyone has ever modified the Clarifier to function as an RIT? It looks like it wouldn't be too hard; perhaps with an opto-coupler and a dropping resistor. I didn't find anything on the mods.dk site.
