You're transmitting a 250kHz square source which is the summation of
all odd harmonics of 250kHz. I believe that is why you were told to
switch over to a sine wave which you would probably just see a single
tone.
Due to bandwidth limitations, transmitting square waves over the air
doesn't work quite as one may expect.

I am sorry if I am unfamiliar, but what exactly are you trying to
accomplish, and how do you expect to do it with a square wave?
