If you're using a multiplier of the I.F., then yes, you will need better stability than we can provide within the constraints of the KX3's hardware. I'll add this to the FAQ for the 2-meter module.
If on the other hand you're using mixing to get from 2 meters to the higher bands, the KX3-2M will work just fine for you in CW mode. 73, Wayne N6KR On Apr 8, 2014, at 4:48 PM, "Dave" <[email protected]> wrote: > Erm, yes, and yes. > > I think that you need to think about what I said that I wanted to use the > KX3-2M for before you try to reply to my complaints that it wont do what I > want it to do. > > I'm not using WSPR or any other data modes, other than CW, and that seems to > be where we are getting confused... > > Dave (G0DJA) > > Dave (G0DJA) > ----- Original Message ----- From: "Wayne Burdick" <[email protected]> > To: "Dave" <[email protected]> > Cc: <[email protected]>; "Elecraft Reflector" <[email protected]> > Sent: Tuesday, April 08, 2014 11:28 PM > Subject: Re: [Elecraft] KX3-2M module will work well for CW and SSB,even as > an I.F. for higher-band XVTRs > > > Dave, > > Are you using a frequency multiplier *applied to the I.F. signal*?
