I have dropped Harry an email about output power, im used to using the wsprlite which ive now sold if favour of the Zachtek desktops, mainly because they have built in filters, yes i could have bought a filter kit but I have glaucoma now so soldering is no longer something i could do. What i was wondering is the drop down output power or custom just for reporting what output power OR can you actually alter the output power of the unit. I can't see any reference to that in the manual. IF it does alter the power output what setting is max and what is minimum in dBm in relation to mw? Love the units though, nice to not have to watch the clock to push the button!
