Receiving, identifying and decoding time signals is an interesting and sometimes challenging aspect of amateur radio.
Time signals have unique spectral 'foot print' which makes them very special!

List of active time signal transmitters, received in Australia (except for MSF, TDF and BBC which were received and decoded in Europe):

Time signals of BPM China received on 5 MHz:

Time signals of WWVH Hawaii and BPM China received simultaneously on 5 MHz:

Time signals of WWVH Hawaii, WWV Colorado and BPM China received simultaneously on 5 MHz:

WWVH Hawaii and WWV Colorado on 15 and 10 MHz:

Another strong reception of both WWVH Hawaii and WWV Colorado on 15MHz. Note very unique 'foot print' characteristics of WWVH.

WWVH Hawaii, received on 2.5 MHz:

And here is a snapshot of very good opening which occurred right on the local sunset: the WWV from Colorado clearly audible and visible. Frequency: 2.5 MHz. ERP: 2.5KW

Decoding of WWV 20MHz : Day/Month/Year Hour/Minute data 'extracted' from AM signal, recording.

Decoding of WWV 10MHz : Day/Month/Year Hour/Minute data 'extracted' from SSB signal, real time.

CHU transmits 3 kW signals on 3330 and 14670 KHz, and a 10 kW signal on 7850 KHz. The signal is amplitude modulated, with the lower sideband suppressed (emission type H3E). The same information is carried on all three frequencies simultaneously including announcements every minute, alternating between English and French. The CHU transmitter is located near Barrhaven, Ontario, Canada.

This is the fotprint of the CHU, as received on 7.850 MHz

Receivers: Perseus, GenesisRadio G59, Icom 7200.
Antennas: PA0RDT Miniwhip, multiband HF vertical.
Time signal decoding software: CLOCK by F6CTE. Spectral analyzer: Spectrum Lab by DL6YHF.
