    Just remembered to look at Andrew s proposed calling freq. list and the new ARRL band plan list on my wall! Do these look OK for digital & SSB modes if one is

      Just remembered to look at Andrew's proposed calling
      freq. list and the new ARRL band plan list on my wall!

      Do these look OK for digital & SSB modes if one is
      limited to a 40KHz total range?

      Note: I want to be certain that at least part of
      each segment is in the USA General Class portion
      so I don't miss those ops.

      DIGITAL
      --------
      Band Low Center Top
      40M 7.035 7.055 7.075
      80M 3.575 3.595 3.615

      SSB/SSTV
      --------
      Band Low Center Top
      40M 7.180 7.200 7.220
      80M 3.780 3.800 3.820

      A quick look at the low cost crystals stocked by Digi Key give the following fits to the desired center frequencies and band coverage. 40m- 28.224 MHz crystal

        A quick look at the low cost crystals stocked by Digi Key give the following fits to the desired center frequencies and band coverage.
         
        40m- 28.224 MHz crystal gives center frequency of about 7.055 MHz with TX band coverage 7.035 MHz to 7.075 MHz
        80m- 14.318 MHz crystal gives center frequency of about 3.579 MHz with TX band coverage 3.559 MHz to 3.599 MHz
         
        40m- 28.636 MHz crystal gives center frequency of about 7.159 MHz with TX band coverage 7.139 MHz to 7.179 MHz
        80m- 15.0 MHz crystal gives center frequency of about 3.75 MHz with TX band coverage 3.73 MHz to 3.77 MHz.
