ERP was about 2 Watt (250W RF power), but I am not confident to run high power over night (unattended). My 500kHz antenna is surrounded by many trees and detunes by many kHz when these get wet. This time of the year the trees are wet in the morning, even when WX is dry (due to condensation). Antenna detuning will decrease the ERP, but will also reduce the PA efficiency.
