VO1NA showing well this morning on the spectrogram,

It seems to be getting better and better.

The actual bearing to VO1NA is 280.1 degrees.

New E-field rx after the recent re-build,

Pre-amp on the left (AD823) slots into the base of the
antenna tube, and connects via 5m of 4-core screened
cable to the power supply (IP1215S), filter (TL071),
line driver (LT1010) and isolating transformer (OEP A262A6E)
in the IP65 box on the right.

Six days of cold dry weather coming up - perfect for
playing with antennas.  Will hopefully finish this
tomorrow and install on Wednesday, calibrate on Thursday.
