This is what I found with the FTM-400 and PMS scanning.
Using programmer version 5.00.47, I set frequencies in the Band A and Band B Limit Memories. I also set Step to 5, 25, 12.5, 50, 100, and Auto.
What I found once I sent the file to the radio.
- I could check the steps two ways....
If the step on the upper and lower limit were different, the radio scanned based on whether I started scanning on the upper or lower channel.
- put the radio into memory mode / select a PL channel / start scanning / touch SCAN again to stop scanning / verify that PMS appears on the screen just above and to the left of the frequency / turn the tuning knob for a or B band and watch the frequencies change based on the step.
- select the upper or lower channel / press and hold Setup to enter the Set Menu / select Config / select 7 FM Am Step / the step is displayed there (this is interesting especially when Step is set to Auto in the program. The radio automatically selects a value for this field.)
I could get each of the steps to work. I verified each both ways I described above.
