Hi Wolf, Yes, I've seen similar signal on my Toshiba Satellit laptop. I can't recall the frequency though. I traced it to be generated inside the PC, and likely to be a battery charger sequence. No a

Hi Piotr, Nice to see your good work again. Do you think it would be possible to present the plot with a logarithmic distance scale. It might also be interesting to try dbuV/m for the strength axis??

Hello Piotr, Again thanks for your work. The comparison of the 3 bands is very interesting. If i include the reduced antenna efficiency it is anyway an advantage to transmit on lower frequencies, at

Daniele, the two carrier segments certainly look right! Only the frequency stepping at 11:20 and 11:30 has apparently been covered by noise. 73, Markus -- Original Message -- From: danieletincani@yah
