LF: FS measurements

[Dick Rollema <dickrollema@casema.nl>]

To All from PA0SE,

Today I made some FS measurements, using an untuned loop with a single
turn of 1 square metre, connected to a W & G SPM-12.
The loop is turned for maximum signal. This is rather broad, so I first
turn the loop for minimum signal, which is sharp, and then turn it over
90 degrees.

The measurements were performed in the attic shack. But I have found out
earlier that on these low frequencies the FS in the shack does not differ
from he FS outside the house.

0.22 mV/m

DCF 38          138.8
kHz            
2.25 mV/m

The station at 135.4 kHz is similar to DCF 38.

I have not recorded the FS of MSF at Rugby.

My location is at Leiderdorp,  52°  09'  37.21"
N;  04°  31'  23.52" E.
