Also part of the "radio space" are Radio Eaters. Most normally viewed partially manifesting into our space via the appearance of will-o-wisp type phenomena near large broadcast antennas, the "domestic" Radio Eaters feed off of transmissions. While the domestic kind offer no danger, they may cause degredation in signal if they are not periodically removed. Far more dangerous are the radio eaters in outlying areas and areas without steady radio broadcasting, for these have a far less steady diet. Affected by hunter, rapid on/offing of a transmitter will cause them to manifest strongly and attack everything nearby. Their threat ranges, from significant in areas recently devoid of radio chatter, to weak in areas that rarely ever get any. Thus, radio outside of constant operation is generally a risky endeavor.
Due to the interference of radio elementals, this also makes it unweildly for military concerns. However, the adventuring community has found ample reason to utilize these devices. In addition to being able to have constant contact with a "base camp", there are a few magical devices that increase the utility of the communication. Charms that provide the surface with a view of whats going on, with upgrades that add magical enhancements, such as Darkvision, Detect Secret Doors, and other similar divinations. Also the Sensory Rod, which when wielded by a radio operator, transmits a plethora of data about where its being pointed (material, thickness, age, etc) to a set of runes which must then be deciphered to gain the knowledge
