As the head is smaller relative to the wavelength at lower frequencies than at higher, the shadowing is also smaller. Therefore there should be more blending of right and left below 1 kHz than at higher frequencies.

My problem only occurred when keying was done from an external keyer. This could happen when keying from e.g. the WinKeyer.
