Keep us updated on any progress (or pitfalls here). I just installed our new MicroSemi S350's a few minutes ago;) and pulled a couple TS2100's out of the rack. We would like to update these and have one of the Heol GPS units on order. Ours have OXCO's already, so it should just be the GPS.

I'm giving the entire rebuild a try including the Ace Trimble III clone form Heol Design. I'm not sure it is practical but I like the idea of keeping an old unit running. I read the post you mentioned which does a nice job of discussing the firmware settings. I was hoping for some practical tips on removing and reinstalling the oscillators. Is it a straight forward desolder/resolder? Is there an insulating pad (thermal or
electrical) under the OCXO? Any pitfalls?
