RNI? - am I confusing that with "Radio North Sea International" (RNSI)? Anchored somewhere off Scarborough, I believe.

But a horizontal radiator such as a dipole produces a skywave only, in a lobe pattern that I think varies according to its distance from the ground. Probably a reflector would be needed to “point” the skywave in the right direction. But a horizontal dipole and reflector for MF mounted at say 0.25 lambda or higher would be rather a large array. Are or were there any such actually used for MF skywave broadcasting?

Wasn't it 675?

Laser used a T aerial and Caroline, after the tall mast collapsed, used the same. Laser always seemed to have the better signal.

turretslug wrote:Good AGC and synchronous demodulation? I suppose similar criteria as for good SW reception would apply, but image rejection and noise performance wouldn't have been as critical, so no need for the 2 RF stages and 4x ganged tuning of the classical behemoths.
