Re: LF: Netbooks for WSPR and Spectrum Lab?

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!
