In my opinion, this growth of HF activity is a good thing. Often the use of these modes is a tentative to compensate for antenna and power limitations. There exists a general problem related to the band plans. Often there is to many space reserved for less used modes, while the allocated space is to small for more popular modes, especially digital modes. The 30 m and 60 m bands are good examples. Often, I'm asking me if the people which decide about the band plans are really QRV. We need more space for digital modes and more realistic band plans. Just my opinion.
