While scanning some frequencies, I came across some digital signal in
the 166-168MHz region that I would like to identify.
The baseband signals are narrow (5/10 kHz) using an unknown modulation.
I had a look at the constellation diagram and all I could see is a quite
The spectrum at the beginning of the burst has 5 harmonics spaced by ca.
1.6KHz, and at the end of the bust it’s just a single spike (and the IQ
signals are almost pure sinus)
I would be grateful if someone could share tips about signal
