      Add a new Packets(NULL) to show packets whose payload is truncated due
      to containing NULL characters.

      Count (but don't display anywhere yet) duplicate packets received from a
      station. This is needed to calculate an accurate unique-packet rate.

      Track (but don't display anywhere yet) the actual start time for hourly
      packet count buckets. This is needed to calculate an accurate per
      minute rate.

      Count "Oth" packets for any packet that doesn't fit a defined type.
      These are the packets that a type (t/) filter can't pick up from a
      filtered feed. These packet counts are display on the port status
      windows (right click in APRS-IS OK pane).

      Restore StationMemory diagnostic window if it exists when selected from
      APRS-IS OK right click menu.

      Restore including trailing spaces in CRC calculations used by duplicate
      packet detector. This may cause additional "Invalid" or "Too Fast"
      track points to be introduced by space-adding IGates.

      Add a "Busy Stations" option to the APRS-IS OK right click menu. This
      will bring up two windows that refresh every 10 minutes and show the
      highest (non-duplicate) packet rates (per minute) for Fixed (no tracks)
      and Mobile (has tracks) stations. If you see any abnormally high rate
      stations in your area, check aprs.fi's raw logs (or do a Control-G
      b/<Call-SSID> test filer) and see what's up. If it looks like they're
      not adhering to local APRS usage standards, give them a call. And if
      it's you're own station, you can toggle on Configure / Beacon / Why to
      see what's triggering the rate. Note: The first number is the current
      clock hour minutely rate. The () number is the previous clock hour rate.

      Make that THREE windows. I just added a Busy on RF window. For now, it
      gets created all the time. Eventually, I might detect if there's
      actually an RF port configured.
