Peter,

I hope the experts like Wolf and S= tefan can help.

Another question for Wolf etc: how would one use a s= ingle PC with two instances of SL running to (a) lock the soundcard to an 1= 8-22kHz MSK signal like GBZ one one instance and then (b) generate a (frequ= ency stable and locked)=A0 output signal for an 8.970kHz TX?

It is some months since I have used SL and I was never what might be ca= lled an "expert user".

73s

Hello VLF,
I like to do some local test here with Spectrum= lab=20 setings (and who knows, High ERP transmissions later=A0 :-)
I have here a notebook that generates a signal = with the=20 Signal generator in Spectrum Lab at 8970.1 Hz.
It has a Loop connected at the input and thats = how it is=20 locked to a GDO (HWU, FTA, what=A0is available)
I tried several, and that Lock wondow gets gree= n, but=20 output looks terrible.
To radiate the signal I use a pice of wire at t= he=20 notebook LS=A0output.
=A0
Below two grab's over the same periode of= =20 time.
My localy generated signal at 8970.100 Hz and f= or=20 comparison the signal of DJ8WX at 8970.022 Hertz.
=A0
Both grab's are made with the same Spectrum= Lab=20 task.
=A0
Why does my signal look like a widband FM trans= mission=20 ?
=A0
=A0
=A0
Best 73's, Peter - PA1SDB
=A0
=A0
