3985 kHzKiloHertz (kHz) 10^3 Hz is a broadcast frequency so this could also be a test transmission from a broadcast station. Carrier can be seen on 3985 kHzKiloHertz (kHz) 10^3 Hz and the spectrum is symmetric on the both sides, typical to AMAmplitude Modulation. In this case, there would be steady tones and occasional frequency (audio) changes. Emcbro (talk) 21:47, 13 July 2024 (NZST)
