UPDATE 2136z: I managed to dislodge the laptop power lead, the battery was very low and the PC shut down, so no WSPR for some while. All now plugged in again and working. Initial results are very encouraging.

472kHz RX with a preamp
I am currently looking on 472kHz with the earth electrode antenna but with a preamp ahead of the FT817. Tomorrow I will check the sensitivity with and without the preamp at 472kHz using a signal generator. Already I have copied a couple of French stations at good strength. Overnight I'll leave the system running to see what I copy. I am not on TX overnight, just RX.
