First off, "all amateur frequencies are wideband" is demonstrably false.

Second, what chirp calls WFM is 100kHz broadcast FM, like what is
available in your car or on several models with 88-106MHz broadcast

I just opened a new chirp page and put in 221.5MHz and it defaulted to
FM, which is 5kHz deviation, and what public safety types would call

See here for more details:


Are you seeing it default to something other than 'FM' for 220?
