  I have finally found the time to get some (radio) work done here and 
got my 2nd tower finished and I erected an inverted L, 10m vertical and 
30m top rising to 15m at the far end. I still have the "earth antenna" 
which is just a length of wire laying on the ground 80m long and 
terminated directly to an earth stake and laying roughly in the same 
direction as the top wire of the L .
Comparing the two gave some very interesting results.

10 MHz  CW                L = S7    earth = S1
7 MHz CW                    L = S9    earth = S3
R. Bristol 1566 KHz    L = 0    earth = S2
Donebach 153 KHz    L = S6    earth = S8
DCF77 77.5 KHz        L = S3    earth = S5
MSF 60 KHz                L = S4    earth = S8

All very non-technical I know, neither antenna was matched or tuned in 
any way and was all done about 13:00z.
There was no noticeable difference in the noise level but when I tried 
it before the earth antenna was very much quieter after dark. I will try 
and repeat this tonight and see what the difference is then.
