[UK-CONTEST] Power Limitations

[Rob Harrison]

Hi Ray,

I find this argument re accuracy of ERP frankly poor. I've put this idea 
forward for consideration for VHF/UHF contests, but it would apply to HF 
also. I get the same old weak arguments against, when frankly the arguments 
for power only are weak too, as they don't take into account antennas of any 
sort, which is bizarre.

Everyone seems to be hung up with the Nth degree of ERP accuracy, surely we 
can agree on generic gain for certain antennas, we know the power out, 
feeder loss, it's relatively simple to work out a figure for any given 
station to within fairly accurate limits. Not taking antenna gain into 
account at all is utterly wrong.

It seems there is a reluctance to even try it, are vested interests at play 
here?
