[Elecraft] KX3-2M module will work well for CW and SSB, even as an I.F. for higher-band XVTRs

[Wayne Burdick]

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.
