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.

73, Dick, PA0SE
