Hi Eddie,

I didn't realize you are the author of the web page that I mentioned in my message below :-)

My compliments also for the very nice grabber page.

Regards

D.

Hi Daniele / Chris et al

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 try 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 screen have a local origin. I am just curious about their source.

 

Following web page http://g3zjo-radio.blog.co.uk/ mentions 11.7Hz as one of ELF carriers visibile at the author's location ("At my urban 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.

Hi all - ZEVS transmitting on schedule from 0800 UTC this morning.

Eddie, Daniele - I don't have an 80Hz carrier 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 (93.72Hz), etc. Does anyone know about a possible origin of these 11.7Hz-spaced carriers (or harmonics)?
