[Elecraft] 2M internal transverter stability

[vr2xmc]

I also experienced frequency drift in my K144V. The drift is worse than other multimode v/u radios.  However, it is ok to use k144v in FM.  I am awaiting product enhancement in k144v.  Having said that, HF of K3 shown good frequency stability.
