The press release indicates that they're using RadioSAFE:
http://www.theradiosource.com/products/radiosafe.htm http://www.theradiosource.com/products/radiosafe.htm
> RadioSAFE Broadcast Systems have the capability of staging hundreds of preplanned safety messages that can be selected locally or remotely at a moment’s notice and updated minute by minute. Programming can be performed at the station or remotely via telco or UHF/VHF transceiver or by LAN/WAN if optioned. Redundant levels of message control are provided in the RadioSAFE design.
An antenna upgrade is offered:

> 300 Watts, 470-1800 kHz, 20+ Mile Radius Range
Various warnings are noted about requiring an FCC license beyond certain transmission power thresholds.

- AWildC182 7y agoThat's one hell of an inefficient antenna. At a ~1MHz center frequency it's basically just a dummy load (resistor) that happens to radiate a little. 300 Watts at those frequencies on a long run of speaker wire with a matching transformer/unun at one end could get you 100s of miles during the day and 1000s of miles at night.
- floatingatoll 7y agoSpeaker wire generally degrades in sunlight, so that might not be a valid comparison for the "disaster-resistant permanent installation" market.
