Tropospheric Radio: Broadcast #01

I’ve been super busy of late with normal life things but I have recently (under  the ever ‘unreliable’ banner of the National Tropospherics Commission) launched a new piece of broadcast art via the diverse and quite wonderful Basic FM.


The premise is as follows (taken from the NTC website):


At 02.35 (EST) on the morning of 23rd May, 2014, during a routine scan of shortwave bands our field agents are known to use, one of our automated remote listening stations near Exton, PA picked up a transmission on a frequency usually devoid of activity.

While we occasionally observe stray interference across our private frequencies, it is generally easily identifiable as such. In this instance the sustained nature of the transmission suggests something intended rather than the result of atmospherics, a stray carrier or other phenomenon.

Lasting exactly one hour, the transmission, as per standard NTC protocol, was captured and sent for analysis which has, as yet, proved inconclusive. Exactly two weeks later, at the same time, a second broadcast was received on the same channel, lasting the same duration and this bi-weekly occurrence has repeated with different content up to the present. This pattern suggests some conscious attempt at communication.

We have as yet been unable to determine the origin and nature of the broadcasts and have therefore requisitioned airtime on Basic Fm and temporarily declassified these transmissions in order to retransmit the anomalies in the hope that they may be decoded or debunked.

As long as the pattern continues, we will re-propagate each transmission in full until such a time that they reach their intended recipients, are decoded or the channel goes dark again.

Retransmission begins at 13:00 (gmt) on 17th of June 2014, on basic fm, and will repeat at the same time every Tuesday and Friday. New broadcasts will be aired bi-weekly for as long as our listening post continues to receive them. Please feel free to follow @TropComms and @basic_fm on twitter and visit for show info.


You can catch the next broadcast as it goes out this coming Tuesday at 13:00 (repeated on Fridays at the same time) but in the meantime, you can stream the first broadcast below.
