[RPG] Gear of the Ancients-

I am beginning to run low on standard hard-tech examples of Ancient technology without simply enhancing stuff we have in our present toolbox, while still preserving them in a 'useful to Player Characters' context.
--Unless I receive requests for specific types of gear, this is likely to be among the last of the HardTech doohickeys I'll present.

That said, here is the super-radio:

Gear of the Ancients-

KSkermAm ('Artifice - Radio - Portable')
* Type: High-power VLF Pulsed Laser-Phasic Radio Communications System
* Range: Line of Sight and over Horizon
* Power Requirement: 01 Unit per transmission to maximum range, less at shorter distances
* Weight: 4-6 Lbs.
* Frequency: M

:: Due to its Very Low Frequency waves and its pulsed nature, the carrier wave is capable of excellent transmission (wave propagation) over bodies of sea, brackish, and fresh water, while drier earth and dense jungles reduce the range to roughly 8.1 miles (at which point the curvature of Urutsk prevents LoS). However in such unfavourable terrain, other factors, such as the extensive and pervasive ionisation of the atmosphere can begin to degrade propagation as early as 4-6 miles.
:: While near instantaneous, there is a discernible delay at extreme ranges, such as from sea to sea transmissions which travel beyond the horizon. The data is compressed, with a multithread factor of 10, and on military models can utilise a ternary/trinary-qubit rough-equivalent of 16,384-bit encryption. Storage memory on most common models exceeds 100 Terabytes.
