Channel bandwidth

The mention of 5 MHz channels appears incorrect.

APNG was an analogue system as stated in the Article.

Analogue systems used 3 kHz or 2.8 kHz channels spaced at 4 kHz or 3 kHz respectively.

The channels were derived by frequency-division multiplexing (FDM). Accordingly the 480 analogue channels in APNG were organised as 40 12-channel groups which were in turn organised into 8 60-channel supergroups.

5 MHz may have been the total 2-way system bandwidth?
