Hello Jim and all:
The signals from SAQ were at similar levels that
last year, around 42 dB(µV/m), equivalent to the Jim´s measurement but at 2100
km from Grimeton. The RF signal/noise ratio around 16 dB, using 200 Hz IF
bandwith filter.

Dear LF Group,
I made an estimate of SAQ's field strength, using
a loop antenna and SLM, which came out to 130uV/m. It is around 1000km to
Grimeton from my QTH, for which the ERP works out to about 340W - which seems
very low. Ground wave losses could account for a few more dB, but I'm sure SAQ
used to be stronger than this - I can't find any immediate fault with the
equipment or the calculation, and other signals come out about the right
level. Has anybody else found SAQ to be weaker than it used to
be?
Cheers, Jim Moritz
