    I'm new to amatuer radio and am somewhat confused by band plans. I looked it up on the ARRL website and that confused me even more. For example, on one page it showed.
    **********************************************************************
    All Amateurs except Novices:
    144.0-144.1 MHz: CW Only
    144.1-148.0 MHz: CW, Phone, Image, MCW, RTTY/Data
    **********************************************************************

    Ok, that seems simple enough to remember. But then on another section of the ARRL website, it showed this:

    **********************************************************************

    144.00-144.05 EME (CW)
    144.05-144.10 General CW and weak signals
    144.10-144.20 EME and weak-signal SSB
    144.200 National calling frequency
    144.200-144.275 General SSB operation
    144.275-144.300 Propagation beacons
    144.30-144.50 New OSCAR subband
    144.50-144.60 Linear translator inputs
    144.60-144.90 FM repeater inputs
    144.90-145.10 Weak signal and FM simplex (145.01,03,05,07,09 are widely used for packet)
    145.10-145.20 Linear translator outputs
    145.20-145.50 FM repeater outputs
    145.50-145.80 Miscellaneous and experimental modes
    145.80-146.00 OSCAR subband
    146.01-146.37 Repeater inputs
    146.40-146.58 Simplex
    146.52 National Simplex Calling Frequency
    146.61-146.97 Repeater outputs
    147.00-147.39 Repeater outputs
    147.42-147.57 Simplex
    147.60-147.99 Repeater inputs


    Notes: The frequency 146.40 MHz is used in some areas as a repeater input. This band plan has been proposed by the ARRL VHF-UHF Advisory Committee.

    **********************************************************************

    There's no way I can remember that. So which is correct? Or, are they both correct? Hope someone can clear this up for me.

    Thanks,

    Mark

    The second one you list is just much more detailed. Print it off or bookmark it & refer to it when you need to. No one expects ya to remember all the divisions across the bands.. that's why there's charts of this nature.

    These are the guidelines by gentlemen agreements and do vary somewhat from area to area. Check with a local ham club to see what simplex and repeater frequencies are used in your area. They 'should' fall within these guidelines but I won't guarantee it...

    The first one is the FCC allocation for 2-meters.

    The 144.0-144.1 MHz: CW Only and 144.1-148.0 MHz: CW, Phone, Image, MCW, RTTY/Data is the rules as set forth by the FCC.

    The second bandplan is not an official (i.e. FCC rule) but is the agreed operating plan. There is nothing that says you can not operate simplex on a repeater frequency. That being said however, if you cause interference to someone else who is following the unofficial plan the FCC sides with the other person. Falls under the "good operating pratice" rule. The same holds for HF bands. While the FCC has set aside sub-bands for CW, RTTY, and Voice. There is nothing in the rules that says you have to stay on certian frequencies within the sub-bands. Here again just don't cause interference to others. Hope this helps.

    Thanks for the clarifications.
