1. A method of selecting audio recordings of radio transmissions for static network storage, comprising the steps of:

  • receiving an intermittent series of discrete transmissions of audio content from a radio channel having a channel identity, by a radio terminal having a terminal identity, which includes a radio receiver, a memory, and a network file server;

    recording, and storing in the memory of the radio terminal at a location identified by a first network address, a first audio file of a first discrete radio transmission;

    sending a transmission report by the radio terminal corresponding to the first audio file, which includes the channel identity, the terminal identity, and the first network address, to a cascade server located on the network;

    querying a subscription database, by the cascade server, for a list of plural client terminals subscribed to receive transmission reports according to the channel identity, and then forwarding at least a portion of the transmission report to the plural client terminals, thereby enabling the plural client terminals for selectively requesting a copy of the first audio file from the network file server of the radio terminal according to the first network address;

    when the list comprises a quantity of plural client terminals greater than a predetermined value, sending an upload command, including the channel identity, to the radio terminal;

    in response to receipt of the upload command by the radio terminal, annotating the channel identity for static network storage, then recording a subsequent audio file of a subsequent discrete radio transmission by the radio terminal, and uploading the subsequent audio file to a predetermined address in a static network server, andsending a subsequent transmission report to the cascade server, which includes the channel identity and the subsequent network address, thereby enabling the cascade server to forward the subsequent transmission report to the plural radio terminals.
