[DXBase] Band plan mapping

[Jim McDonald]

I wondered why a needed CW spot on 1832 didn't show up in my DX Info window.
I found that I had selected only CW on 160 for alerts.  I doubt that I had
ever looked at the band plan mapping (under Tools | User Options) before.  I
changed some of the defaults, including 160 to reflect the current DX window
which is 1830-1835.  I also inserted PSK31 on 15 and 10 and widened the RTTY
ranges.  You may want to tweak yours too.
