What would you like?

The original plugin tuned in 100 Hz steps. This was increased to 1000 Hz (1 kHz) per press, which is far more
practical for HF operating. At 100 Hz steps, moving 5 kHz across the band required 50 button presses.
Original:
radio.frequency + 100 / radio.frequency - 100
Suggested
radio.frequency + 1000 / radio.frequency - 1000

Or a user selectable step as a variable in streamdeck button.
