Let's not overlook that SNFM does not use 2.5 kHz steps - it uses 7.5 kHz steps/channels in the PS world and the bandwidth is 11.0 kHz.
Only SSB would use a "2.5 kHz step". I have a scanner that does 7.5 kHz steps, but it does not support SNFM. So, you're on the correct frequency but still on the wrong mode (still on NBFM). Joe M.
