+And finally:
+
+Increasing FT8 usage on the popular bands 40, 30, and 20m means that
+the default 3 kHz sub-bands are often wall-to-wall with signals.
+Overcrowding encourages some to turn on their amplifiers, which only
+makes things worse.
+
+As a trial, and in response to numerous suggestions from around the
+world, we have added a second set of suggested dial frequencies for
+FT8 on these three HF bands. The new frequencies are 7.071, 10.133,
+and 14.071 MHz.  They will appear in your drop-down band-selector list
+only after you go to the "Settings | Frequencies" tab, right-click on
+the frequency table, and select "Reset".  Alternatively, you can add
+the new frequencies manually.
+
+When the conventional FT8 sub-band on 20, 30, or 40m seems too full,
+please try moving your dial frequency down 3 kHz!
