Hello VLF,
I like to do some local test here with
Spectrum lab setings (and who knows, High ERP transmissions
later :-)
I have here a notebook that generates
a
signal with the Signal generator in Spectrum Lab at 8970.1
Hz.
It has a Loop connected at the input
and
thats how it is locked to a GDO (HWU, FTA, what is
available)
I tried several, and that Lock wondow
gets
green, but output looks terrible.
To radiate the signal I use a pice of
wire
at the notebook LS output.
Below two grab's over the same periode
of
time.
My localy generated signal at 8970.100
Hz
and for comparison the signal of DJ8WX at 8970.022 Hertz.
Both grab's are made with the same
Spectrum
Lab task.
Why does my signal look like a widband
FM
transmission ?
