Analog radio usually use lots more bandwidth, maybe that's why.
- philpem 8y agoNot always. 25kHz "wide NFM" is still common where licences have been grandfathered in, but 12.5kHz "narrow NFM" is becoming more common. 12.5k NFM has the same signal bandwidth as a timesliced (dual timeslot -- two virtual channels per physical RF channel) DMR or APCO P25 signal.
- jcims 8y agoInstantaneous use is the same but channel management does probably make P25 more efficient for a bunch of departments to independently operate in limited spectrum.
