Hi STx, Yes Could be, that's what will happen, will Knock the power down, and close Radio 4 Mod, same as 162Kc...
Someone asked them, if they could rent airtime, on the existing 162kc Blank carrier, but they said no.

Any idea STx... If Alan B has done any Simulations? on the 5 mast array? with the directional problems you tested
Many many years ago, I did EZNEC Simulations for several FM VHF Antennas, Amazing program very good

The main problem, with doing the 'Model' for EZNEC, is the Ground type/ soil etc....
But for the 5 mast array, would be straightforward, as a fortune was spent on the earthing systems there...
It Had to be good, because of the high power it ran then

With the VHF Simulations, We did One 'Model', then copied it, and altered different things on each Copy
Suppose I ought to Email Alan, and ask, If he has done any recent simulations...
Last time I spoke to him, we were wandering about a seaside town, discussing antennas and SSDAB

I think Nowadays, there is better software available than EZNEC to optimise Antennas....
As if this was sorted, would be more efficient, and use Less Electric, for the same ERP Out
