The OT2m has a built-in solid state relay that's rated at 30 amps, 
though I wouldn't push it that far for very long.  I know it's been 
successfully used with the TS-2000 at 100 watts.  It'll transmit at 300 
baud and the code is out there for PSK31, though I don't think anyone's 
using it.  But you're right, the big problem is frequency stability.
