The effects of electromagnetic interactions on pseudoscalar decay constants are investigated. Using a compact QED and QCD action we are able to resolve differences of about 0.1 MeV. We obtain the preliminary results fpi0-fpi+/- =0.09(3) MeV and fD0-fD+/- =0.79(11) MeV for light and charmed pseudoscalar decay constants on a Nf=2 nonperturbatively improved Sheikholeslami-Wohlert ensemble.
