Just an additional note to clarify the usage of the extra channels. Note that some are Canadian and the other is depreciated.
Many NOAA Weather Radio receivers are also programmed for three additional frequencies; 161.650 MHz (marine VHF Ch 21B), 161.775 MHz (marine VHF Ch 83B) and 163.275 MHz. The first two frequencies are used by Canada for marine weather broadcasts. 163.275 MHz was used by the National Weather Service for earlier weather broadcasts and later for internal coordination in the event of a power outage but is no longer in active use.

ok Jim,
What in the world is the PA and number in the alpha supose to stand for. and adding the marine channels into the NOAA is confusing to others thinking there is new channels for NOAA on which those frequencies should be under the marine and not under the NOAA Alert. Just all very confusing.

I know this stock config was recently reworked (by "recently" I mean in the last year or so). I just did some quick research to validate the frequencies and alpha tags and the following is what I found. >From wikipedia (https://en.wikipedia.org/wiki/Weather_radio <https://en.wikipedia.org/wiki/Weather_radio>) <quote> The "official" NOAA WX numbering scheme does not increase in frequency order because the weather channels were created gradually over the years. 162.55 MHz was at first the only frequency (so was thus WX1), then 162.4 (WX2) and 162.475 (WX3) were added later to prevent RF interference. The others mainly came into use in the 1990s in less-populated rural, areas and as fill-in broadcast translators relaying an existing station or sending a separate, more localized broadcast into remote or mountainous areas, or those areas with reception trouble. </quote> The following is from the NATIONAL WEATHER SERVICE MARINE PRODUCTS VIA NOAA WEATHER RADIO page (http://www.nws.noaa.gov/os/marine/wxradio.htm <http://www.nws.noaa.gov/os/marine/wxradio.htm>) <quote> NOAA Weather Radio Frequencies 162.400 MHz (WX2) 162.425 MHz (WX4) 162.450 MHz (WX5) 162.475 MHz (WX3) 162.500 MHz (WX6) 162.525 MHz (WX7) 162.550 MHz (WX1) Channel numbers, e.g. (WX1, WX2) etc. have no special significance but are often designated this way in consumer equipment. Other channel numbering schemes are also prevalent. </quote> And also from the same page <quote> Many NOAA Weather Radio receivers are also programmed for three additional frequencies; 161.650 MHz (marine VHF Ch 21B), 161.775 MHz (marine VHF Ch 83B) and 163.275 MHz. </quote> So according to the above, the stock config looks fine to me.
