John, The KX3 has "dual watch" (up to +/- 15 kHz VFO A and B separation within the current band). But it does not allow the VFOs to be on different bands. (The K3 allows VFO INDependent in conjunction with the sub receiver, which also has its own front end filters, allowing simultaneous receive on two different bands).
To do what I think you require on the KX3, you could set up 160 m and 80 m for the desired frequencies, then hit BAND+ or BAND- to go from TX to RX. It's still just a single switch press. Regarding 475 kHz receive: My guess is you'll want to use the up-converter. The KX3's sensitivity and image rejection is optimized for the ham bands, and I'm not sure it will meet your needs at this frequency. 73, Wayne N6KR On Oct 25, 2014, at 4:27 PM, KB5NJD <jlangri...@sbcglobal.net> wrote: > Good Afternoon, > > I recently received my KX3 and its amazing. > > I am very active on the 630m band as a Part 5 experimental station and use > an outboard transmit downconverter with an 80m IF to generate a signal. > While I have RX upconverters that port to various bands, the native RX seems > ok so at least at first I plan on using the internal general coverage RX. > > I just ran into a problem, however.
