Paul ,



 looks like a advance case of 'Asperger syndrome' ?



But on a more technical note , I did a little 'work' on propagation on 500 
last year,

with the help of the two excellent grabbers that have been providing a most 
useful

and consistent, window on the band since it was allocated.



My self and Gary, have made good use of the facility's during some of our 
combined experiments. Birmingham being some 75 miles by direct path and 
Shetland round 600.

I have never experienced, previously reported, conditions, where the signals 
from inside the Uk could not be viewed simultaneously, even the low powered, 
multi mode beacon can be viewed.



Interestingly, Though, the antennas in use at all three 'tx' sites are of 
the loaded short vertical format , which when modelled , are demonstrated to 
produce a very low angle of radiation , with very little skyward 'loss', the 
calculated efficiency may not be very high, but it's a case of



'its not what you have , its what you do  with it'



This is in stark contrast to  the somewhat gauche large wirer arrays , 
previously described , which by  ground coupling alone, fail to  establish a 
suitable wave front to  communicate over such distances , instead, radiate 
most effectively in a perpendicular mode .



The three carriers represent no more than 20 mW erp each are fed to a 35 
foot top loaded inverted 'L' , and can be seen to  provide an adequate trace 
for the purpose of the experiment

I'm sure either Gary G4WGT of myself, or others would be quite happy to run 
any experiment's you may want to undertake.
