Russian Buzzer 4625KHz 2308 21 March 2022

(1/1)

JustGreg:
The Russian has a fair signal tonight.  But, in my waterfall, there appears to be another signal, maybe LSB.  Is anyone familiar with the Buzzer and is this just part of the normal signal.  Or, I am just seeing things.  Thanks in advance for any help on this.

Here is a screen shot of the waterfall.

Nomadiq:
I’ve seen it too. My feeling is it is a digital signal just up from it. The digital signal is sometimes seen in Europe but not as strongly so I think the digital signal is from North America.

JustGreg:
Thanks for the help, Nomadiq.  Take care in these strange times.
