Hi Leroy, When you place the rig in diversity, both receivers run directly off the main (VFO A) synthesizer, period. If you are in diversity and TX on your RX frequency, VFO B is not being used for anything.
VFO B remains independent so that such as split operation is possible. Having VFO B hard reset to the VFO A frequency going into diversity would blow up many common operating procedures. Operating diversity, or not, listening to an up 2 frequency for a TX operating spot can be necessary. In split mode with diversity on, a double tap to the SUB button has me listening to the TX frequency in the right ear, and a hold on the SUB puts me back in diversity, **without losing my TX frequency** on VFO B. It is possible to get K3 diversity to the audiophile's "sound stage" level, where the band noise spreads all around the audio "horizon" and CW signals come from point sources. Has mostly to do with the various RF, AF, PRE, AGC settings, and using RX antennas with deliberate varying patterns. When the pileup or weak-signal-plus-noise is spread around the sound stage, diversity is really neat, and amazingly helpful. That is at the point where you have fed enough and proper information to the headphones for your brain to separate everything out like a conversation in a noisy crowded room. This is not the same thing as diversity for the sake of not having both channels fade out at the same time. If one has not experienced a pileup on a K3 diversity sound stage, you haven't yet experienced what it can do. 73, Guy K2AV On Sun, Jul 3, 2016 at 12:17 PM, lmarion <[email protected]> wrote: > All of the RADAR and beacon systems I worked on before I retired from the > FAA > > used diversity receive.
