Today we’re testing an analog modulator (TDA2030 + 2SC5200).
Audio sounds pretty solid to our ears at around 90% modulation depth.
We’re keeping the bandwidth tight at about 10 kHz.
You can sometimes catch us on the 90-meter shortwave band, right around 3280 kHz.
Transmitter filter dialed in at 9 kHz — looks like we’ll be on the air today.
Catch us on the 90-meter band, frequency 3280 kHz.
Tx power is 15 watt. Amplitude modulation, as always! ✌️
@msv641 Yes, it may have been our signal. Our playlist does include several songs in Russian. If it’s not a secret, could you share roughly what region you were receiving from and what equipment you were using?
Ahoy! Broadcast today, 5 march 2026, on 3280 kHz, 90m shortwave band. 25W transmitter. Check your antenna, tune your receiver, and listen for the signal drifting through the ether. Free radio lives!
