Een zo te zien erg leuk en informatief boek (Engels) over werken van DX op VHF/UHF. Gratis te downloaden in PDF-formaat op het linkje hieronder.
This is Roger Harrison VK2ZRH with a few words about signal strengths,
mirrors in the sky and Foundation operators accused of running more power

licensee complain about Foundation operators apparently running more power
than allowed because – quote – some of them are SO STRONG that they’ve
gotta be running more power than ten watts – end quote.
