WebbSome particularities of the VLF and LF transmitters and the signal of which is sampled by the different receivers, are also reported in Table 1. Their location is also shown in Fig. 1. The list of the VLF/LF radio signals sampled by each European receiver of the network is shown in Table 2. Webbtransmissions can be selected in the VLF band from 10 to 25 kHz, or in the LF band from 60 kHz to 75 kHz. Reception is, therefore, not limited to one or two trans-missions as has previously been the case with "economy" model VLF or LF receivers. Some of the transmissions which can be received strongly in the United States are: NAA NLK NSS … coffee odds

WebbThe history of ELF/VLF research had its start mostly in audio recordings, since ELF and VLF studies fall in the 300 Hz – 30 kHz, the frequencies range the human ear can recognize. Early ELF/VLF researchers would simply play the signal received by an antenna straight through a speaker. Hence, we can listen to the data stream as if it were audio. Webbful generation of VLF-HF receivers which are top-end products benefiting from many years of experience in this field. All members of this family are based on the ¸EK890 basic model.
