Is the K3 capable of dual receive with just VFO A and B ?
No. You need the subreceiver option to hear two signals at once. Please consider providing these 3 functions, especially useful for stereo diversity reception: 1. Option for the subreceiver settings (mode, BW, PBT/shift, AGC) as well as the VFO to automatically track the main receiver settings. AF/RF gain would remain independent. These are already either supported or on the list. 2. Option for RIT to change both the main RX and sub RX frequency. Added to the future feature list. 3. Single button press that would “push the context” of the main receiver to the subreceiver if the receivers are otherwise acting independently. Already present. There’s also a menu function B>A to push VFO B settings to VFO A. This is something you can store to one of the programmable PFx buttons.
