Hi Brian Congratulations on grabbing Larry the first night. I can't tell
accurately what it was like last night from the SXV plot, but it looks about
'normal'. Whilst the CME arrived on the 5th it could well be maybe 3 or 4
days later before any effect is felt in the LF radio sense. Certainly the
0300-0400z slot is usually a good one for the transatlantic path W<>E.

I'm glad the 100.030kHz  100Hz BW  filter has proved useful. I still have
some faulty ones if anyone wants to play (the metal can needs desoldering
with a blowtorch to get at the works)

I have also come across a small simple PCB by DJ8ES that has a Analogue
Devices log converter ( AD8307.....  90dB range 500MHz BW !!) and a LT
serial i/f  (I2C I think) A/D in VHF Comms. Not too useful if you want to
use the soundcard but handy for straight logging via the IF output. I dare
say this could be connected up on veroboard.

Cheers de Alan G3NYK
