During this time Very Low Frequency ( 3 – 30 kHz ) signals will be reflected by the D layer instead of the E layer, where the increased atmospheric density will usually increase the absorption of the wave and thus dampen it.

Frequency and timing of spawning may be related to the occurrence of rain.

* LFO-A Low Frequency Oscillator may or may not be voltage-controlled.

The result of these two factors is that the usable spectrum shifts towards the lower frequencies and into the Medium Frequency ( MF ) range during winter nights, while on a day in full summer the higher frequencies tend to be more usable, often into the lower VHF range.

This allowed Virgin's VHF ( Very High Frequency ) timetable to be progressively introduced through early 2009, the highlights of which are a three-trains-per-hour service to both Birmingham and Manchester during off-peak periods, and nearly all Anglo-Scottish timings brought under the 4 hours 30 minutes barrier — with one service ( calling only at Preston ) achieving a London-Glasgow time of 4 hours 08 minutes.
