To All from PA0SE
In a previous message I reported that SAQ generated a field
strength of 572 microvolt/metre at my location.
I tried to find the EIRP of SAQ using the propagation curves of
CCIR recommendation 368-7.
Earlier I have used the curve for "Land" (conductivity
0.03S/m; diëlectric constant 40), to find the EIRP of DCF139, 500km form my
location. That produced an EIRP of 45kW, near the 50kW specified for that
station.
I therefore used the same curve for SAQ. Not having the
locator for Grimeton I measured the distance on a 1934 map of Europe and found
about 800km.
Applying the CCIR curve resulted in an EIRP for SAQ of
6.5kW.
There are many uncertain factors involved so please take this value
for what it is worth.
