I've also done an NJ2L (he's now K2UA, btw) mod to a Realistic HTX-100
ten meter monoband rig.  That radio is now at N5XU, the club station of 
the University of Texas Amateur Radio Club, and is hooked up to a DEMI 
222 MHz transverter.  Even though the HTX-100 is a very mediocre ten meter
rig, at best, that combination performs as well or better than the 
Yaesu FT-726R does on 144 MHz into a very similar antenna at an almost 
identical height.  If the DEMI transverter was attached to a Kenwood TS-850,
it would be a superb combination.
