<html><body><div style="color:#000; background-color:#fff; font-family:verdana, helvetica, sans-serif;font-size:14pt">Airband for voice is pretty much universal around the world. Voice channels are medium band. <br>The VHF airband uses the frequencies between 108 and 137 MHz.
The lowest 10 MHz of the band, from 108–117.95 MHz, is split into 200
narrow-band channels of 50 kHz. These are reserved for navigational aids
such as VOR beacons, and precision approach systems such as ILS localizers<br><div><span><br></span></div><div><br></div> <div style="font-family: verdana, helvetica, sans-serif; font-size: 14pt;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12pt;"> <div dir="ltr"> <hr size="1"> <font face="Arial" size="2"> <b><span style="font-weight:bold;">From:</span></b> Dan Smith <dsmith@danplanet.com><br> <b><span style="font-weight: bold;">To:</span></b> Discussion of CHIRP <chirp_users@intrepid.danplanet.com> <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, January 3, 2014 10:04 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [chirp_users] UV-5R Plus - Wide vs. Narrow Band<br> </font> </div> <div class="y_msg_container"><br><div class="yqt0926267788" id="yqtfd76800">> On the Chirp UV-5R Plus programing, on the channel tab there is a column<br
