T-230-1A 'Mahovik'
From Signal Identification Wiki
T-230-1A Маховик, "Flywheel" in Russian, is a PSKPhase-Shift Keying based mode that can transmit both voice and data. It is transmitted from a Russian T-230-1A radio transceiver. From the signal, it seems to support at least BPSKBinary Phase-Shift Keying (1 bit per symbol) modulation.
The current invasion of Ukraine has spawned several of these signals.
