Frankfort Weather.US provides 14 channels of VLF impulse data, using two types of receivers with various configurations. Normally, all H 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°.
1439 CURRENT H Config: "dual 90° + Horizontal C"

Sampled Raw Impulse VLF energy spectrum. Polled examples may not reflect the same signal across displays.
May be 'blank' depending on network, data activity extremes, server cache purge..
Additional 'real-time' "Server Processed' station and channel data can be selected at the "Server Signal' menu list below.

Controller Status
All systems operate in full manual mode: Relative Gain ADC computational reference trigger level of 100mv.
No 'automatic' functions. Those parameters would change ONLY under extreme conditions or experimental purposes.
