Hello Mark, LF, Finbar an I have a nightly sked, conditions allowing, at 11pm local on ~502.5. Recently been troubled by lightning static which has curtailed many QSOs. We've both also recently been testing home-brew Field Strength metering equipment for ERP verification and are attempting to stay within what our gear tells us is 100mW ERP. We may be over or under estimating, but should be within a dB or 2. At least we're trying to be scientific about things, rather than just turning the wick up "far enough". Make for interesting listening! Have a listen later. John
