I apologise for not getting back to you earlier Laurence. 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!

Any noise from the USB psu/bus at LF Peter? I had issues up in Alaska within 
common mode/ noise at 137kHz.

Hi  Roger

I use a small notebook Archos 10 with Xp OS and a SignaLink USB box
which has a data cable to the the FT-817 to run WSPR (used mainly for HF
antenna comparative tests). The Archos is also used with with the
AIM4170 impedance analyser and another bit of kit for measuring and
displaying signal levels. The latter two items use the old RS232 port
but nevertheless will run with the Archos by using an RS232/USB converter.

Regards

Peter, G3LDO
