The WSPR setup was not connected up because I was using the FT-817 for something else. I dont have LF antennas any more but I checked for possible radiation from the USB psu/bus by connecting a short wire antenna to the FT-817 and wrapping it around the USB lead. No noise detected on the WSPR screen. Probably not a good test! Regards Peter G3LDO > Any noise from the USB psu/bus at LF Peter?
