Hi Graham, LF,
Well it has taken me 25 minutes to get a decode, it is not obvious how to set the Rx & WSJT.
I have the Rx on 501.670 KHz, USB, 400 Hz filter which places the signal base-line at the zero position on the waterfall screen & bingo I got text. 
(copied from save decoded file).

Hi ..All

Running , JT65-A  Beacon on  503 Khz
(ish bit hard to  define)
Tx bandwith looks like   502.95  >  503.15
Tx Dial frequency   501.7 Khz
mode  USB
My  Tx  in  'odd mins'

Rx is active
I am using the 'WSJT6' software , but there is now a second system , part of multipsk , 

http://f6cte.free.fr/MULTIPSK_TEST_06_03_2008.ZIP
The multipsk unpacks and runs with very little fuss , has a usefull close in mode .
NB , you dont need to tune 'onto' the frequency as long asits in the spectrum plot 
it will resolve ... had me condfused for a while ...

Reports welcome

Tnx

Graham
