Frequency: 4625 kHz
Equipment / SDR Used:
KiwiSDR, Székesfehérvár, Hungary / Utrecht WebSDR, Utrecht, Netherlands
Observation:
During this short monitoring session, the normal UVB-76 buzzer was present on the local KiwiSDR in Székesfehérvár, but I noticed an underlying pip-like signal beneath the continuous buzzer. It was similar to the short pips transmitted by other Russian military stations, but distinct from the squeaky wheel tone.
To record the signal more clearly, I switched to the Utrecht WebSDR, where the pip was more audible, though still accompanied by the UVB-76 buzzer.
Notes:
No other unusual activity was observed during this session.
This observation may be of interest to others monitoring 4625 kHz or UVB-76 for secondary signals.
Questions for the Community:
Has anyone else picked up similar underlying pips on UVB-76 recently? Any insights into what this might indicate?
