I tested Skimmer in EUHFC and intend to use it again in WAE mainly above 7030 kHz :-) Mine is 455 kHz IF SDR similar to DH1TW design but covering both FT-1000MP RX. Considering only 20 kHz passband available, sampling frekvency is on 466,667 kHz. This approach takes advantage of built-in wideband filter skirts on 8/45 MHz. 73 de Mario, S56A
