I believe 6474 kHz probably falls within the definition of the 40 meter band on the K3. (I'm not home now so I can't check.) So when you jump back to 7050 the P3 does not use the per-band start/stop frequencies stored in EEPROM (since you haven't changed bands) but instead uses the algorithm for changing frequencies within a band. The algorithm prefers "even" start frequencies, meaning frequencies divisible by 100 kHz, 50 kHz, etc. I probably should tweak the algorithm so that if the band edge ends up too close to the K3 VFO frequency it moves down a bit to center the VFO better.
