Dave, My interest in the KX3-2M has almost entirely gone after this news about the frequency stability, and there is no way to lock it to another high stability standard. I have already completed the extended VFO temperature compensation procedure. I suspect that I will either rebuild my own 28 to 144 MHz transverter which was stable enough or purchase a more modern high performance transverter such as the HA1YA unit for driving my SSPA for 144 MHz EME and terrestrial DX, which only needs a few watts of drive.
I am interested in the PX3 however :-) 73 David Anderson GM4JJJ > On 7 Apr 2014, at 19:07, "Dave" <[email protected]> wrote: > > I'm hoping to use it with a 24GHz transverter, so I guess I'll be embarking > on the extended VFO temperature compensation procedure at sometime after > deciding on whether to purhase the KX3-2M unit. > > However, the more I hear and read about the KX3-2M, the more I'm thinking > that it's not going to be good enough.
