[Elecraft] The "d" at 7038 is growing

[V Cortina]

I've been meaning to ask about this for months.  Not continuously, but consistently, there is a CW signal which just sends the letter "d" over and over, with an occasional other letter.  This goes on day and night literally at any time.  Now today at about 7038 I hear my old "d" friend, and now somebody else at nearly the same frequency sending "p".  Does anyone have any idea what the heck is going on?
