Frankfort Weather.US provides 14 channels of VLF impulse data, using two types of receivers with various configurations. Normally, all H field (m) channels operate in Vertical polarization mode, but 1439 may configure H2 (channel C), for Horizontal mode, while H0 and H1 move from Delta 60° to dual 90°.

Blitzortung receivers detect atmospheric discharges, but the network only attempts definition and location of Cloud to Ground lightning discharges.

Controller Status All systems operate in full manual mode: Relative Gain ADC computational reference trigger level of 100mv. No 'automatic' functions are normally activated. Those parameters would change ONLY under extreme conditions or experimental purposes. The following examples illustrate some systems information available only to administration
