MW/AM 1KHz-2KHz off frequency with 10KHz steps #12

I'm Using an ATS-25 running 3.4.

Being that I'm in North America and tune in 10KHz steps the frequency range (522KHz-1701KHz) doesn't really do well when you continuous tune (going from the bottom of the band and loops to the top of the band when you keep tuning down), you'll either be 1KHz off frequency, or 2KHz off frequency depending on if you're continuously tuning down, or continuously tuning up and loop around because it either loops up to 1701KHz, or loops down to 522KHz.

I'm new at this, so modifying the sketch is out of my comfort zone right now, looking at the sketch is about as far as I'm comfortable at doing.

I was thinking of possible solutions to this issue.

  1. Creating 2 MW buttons, a MW button for 530KHz-1700KHz for 10KHz stepping (for North America/South America), and one MW button for 531KHz-1701KHz for 9KHz Stepping (for Europe, Asia, Africa, Australia, New Zealand). Maybe call the buttons MW10 , and MW9 for their respected stepping and frequency ranges.

  2. The tuning bottoms out or tops out and doesn't allow you to loop around continuously (I like being able to loop around as it gives you a quick way to go from the bottom of the band to the top of the band without having to manually type in the frequency).
