In my (subjective) listening before and during the contest, I couldn't tell much difference between the stations on 40 and up, but I did notice big differences in their signal strength on 80m. On 80m some were easy to copy here, and some down in the mud.

It would be relatively easy to equalize transmit signal strengths however:

Have each station transmit in a set sequence like the 14.100 beacons. Then a receiver (probably on another continent) with a calibrated s-meter could measure the relative strengths. Do some averaging, and repeat for each band.

>From this, work out the required power output for each station on each band to equalize signals. It would be then very easy to use a wattmeter to monitor the power output from each station and for example disable the PTT line to the amp if the maximum allowed for that location/band is exceeded. A similar function  is used in several wattmeters to disable the amp if the SWR is too high. The LP-100 wattmeter for example could probably do it easily with different settings on each band (frequency is automatically measured by the meter).

There might be problems with obstructions/hills affecting one direction. Also,
equalizing locations for receiving (local noise) would be much harder.
