I have a problem with my mb1
when I turn it generates a number of carriers which I note on my spectrum, and I feel even on my k3.
the carriers are seen up to 12 MHz.up to 5MHz it is very strong then drops in intensity.
over 12 MHz does not seem to present.the carrier seems to repeat itself every 743 khz around
the carriers are also present in the ham bands
Excuse Vasily if I have not updated anymore.
The problem has not been solved but I have identified the cause.
Is the communication cable cat.
If I disconnect, the signal disappears.
As soon as I have some time I will try to make it a new one or I will use ferrite
We recommend using CAT6 shielded Ethernet cables to minimize it.
Also some LAN devices like routers, PCs LAN-cards can generate these carriers.
If you'll add ferrite beads on top of that, it would be even better.
