Audio System
Radio Frequencies
Your Honda's radio can tune in all
frequencies in both the AM and
FM bands.
Those bands cover these frequen-
cies:
AM band:
530 kilohertz to 1,710 kilohertz
FM band:
87.7 megahertz to 107.9 megahertz
Radio stations on the AM band are
assigned frequencies at least 10
kilohertz apart (530, 540, 550).
Those on the FM band are assigned
frequencies at least 0.2 megahertz
apart (87.9, 88.1, 88.3).
Stations must use these exact
frequencies. It is fairly common for
stations to round-off the frequency
in their advertising, so your radio
will show a frequency of 100.9 even
though the announcer may call the
station "FM101."
