All SID monitoring stations are homebuilt by the observers. Instructions for constructing the VLF receiver and antenna are available on this website under the SID Monitoring Overview section.

WebVery Low Frequency (VLF) communications transmitters use digital signals to communicate with submerged submarines on at frequencies of 3-30 kHz. The eighteen Trident submarines constitute about half the US strategic nuclear capability. The supporting infrastructure for these submarines includet connectivity links such as the Extremely Low ... WebA VLF receiver measures the field tilt and hence the tilt profile shown in figure 1 (Klein and Lajoie, 1980). Figure 1 also shows schematically how the secondary field from the conductor is added to the primary field vector so that the resultant field is tilted up on one side of the conductor and down on the other side.
