I contacted Jim to see if he'd turned up the power, or used a Yagi. He replied that he was just using an extended double Zepp wire, with one of its lobes directed to Europe.
To put a +16dB signal into context, I can expect a signal of about that level from ground wave if I run a quarter wave vertical on 200mW, but only 9.5km away from my receiving vertical delta loop!
The plot below shows AJ8S/1 either side of the 'wow!' event:

| AJ8S/1 shows an unbelievable, transient signal strength spike. |
Here's how Jim was heard in general at the time. On this side of the Atlantic, the next strongest reception report was 10dB weaker than mine:

Incredible isn't it. One of those occasional occurances. I received AH2C from Hawaii on +2dB peak this morning on 60m, other spots were at a range from -12 till -22dB. 73, Bas
