inspiration.

The transmission from Dex coincided with the second night of
reception of Bob's signal.   I put the two bands together in
this image

Dex informs me he was transmitting 2014-03-02 17:00 to
2014-03-03 12:00 so I have only picked up part of the transmission.
Propagation must have taken the rest.

In USA does an experimental license have to be obtained for 8.27kHz ?

Maybe not. I would say, take whatever antenna you have and put some voltage
on it.  Recent history of VLF amateur operations is characterised by
pleasant surprise at how well a small ERP can be detected at long range.

And Mike and Markus too, with the latter currently carrying the distance
record I believe - I make it 6451.7km from Bob to Nuernberg.
Dex to Todmorden is 6196km but with less ERP.

As always, the pleasure of taking part in a team effort far exceeds that of
any individual accolade.
