Phase noise is quite low on 2 meters, since the LO for 2 meters is derived directly from the HF-6 meter synthesizer. We'll post measurements on this soon.
The 2-meter module can be used on CW, SSB, and some data modes once the temperature compensation is applied. It is not just an FM/AM unit. 73, Wayne N6KR On Apr 8, 2014, at 2:36 PM, "Dave" <d...@g0dja.co.uk> wrote: > That sounds OK, at first glance Wayne, > > But, what about the phase noise of the LO?
