I will take a good look at  the ZEVS= breakfast code in moment, I have a burst of noise covering the start bit.=

OK on the 11.7Hz Daniele, I will take a close look there too to tr= y and establish if it is a received signal. These cariers are too stable= to be from local devices I think.

Hello Chris,
 
I have no doubt that that 11.7Hz-spaced lines on my SpecLab scre= en have a local origin. I am just curious about their source.
 
Following web page http://g3zjo-radio.blog.co.uk/ mentions 11.7H= z as one of ELF carriers visibile at the author's location ("At my urb= an location there are several carriers visible, 5.9Hz,8.8Hz,11.7Hz= ,16Hz, 23Hz and 32Hz") but it does not tell anything about= the possible origin.

D.

Hi all - ZEVS transmitting on schedule fro= m 0800 UTC this morning.

Eddie, Daniele - I don't have an 80Hz car= rier here at IO92vf. I'll look out for the others.

Sorry Daniele no idea 1.7Hz and multiples.
Both Stefan and I have an 80Hz constant carrier, I am also pretty sure= about 16Hz 32Hz and 64Hz being received signals.
Perhaps the growing= band of listeners can confirm these as also received elsewhere.

I see a constant trace at 82Hz, but it appears to be 7 x 11.7Hz, as= I see other similar traces at 6 x 11.7Hz (70.28Hz) and 8 x 11.7Hz (93.72H= z), etc. Does anyone know about a possible origin of these 11.7Hz-spaced= carriers (or harmonics)?

Daniele
