I studied the front panel for differences and put red rings around them. The three to the upper left have to do with the new display bezel with silver instead of black screws, the S in K3S, a built-in marker for the VFO A knob, and a soft-touch VFO A knob.
In addition to the marking with OFS (offset) to the left of the RIT/XIT control, there are two markings that also reflect what my present K3 with the latest firmware does:
- APF instead of DUAL PB (Audio Peaking Filter - Dual Passband) - upper right
- New marker for DIV - Diversity reception - to the left of VFO A
It sure would be nice to get stickers with APF and DIV to put on mine!
