Yes, Alpha amplitude was logged at the same bandwidth during the test. The average amplitude of the central 11904.761Hz component during the 90 minutes analysed was 11.6fT, but there is probably 50%
Hello Paul, do you know the difference (signal strength) between Stefan's signal and the 11kHz Alpha signal at your place? This would give me (and maybe others) a target for my 8.97kHz RX setup. 73,
