Codan Chat HF Data Software

Codan Chat software provides fast, secure and error free peer-to-peer text messaging, file transfer and email over HF when used in conjunction with a Codan radio (text only) or Codan radio and modem.


The Codan Chat Console provides a familiar easy to use Instant Messenger (IM) style interface for typing messages. A quick message can be sent and the HF link closed or the link can remain open for a full chat session.


Short text messages can be sent using the Codan Chat Console from two radios each connected to Codan Chat using a PC and keyboard. All messages are logged for later review if required. Messages can also be sent from a radio using Codan Chat to a radio that does not have Codan Chat attached and vice versa.


The in-built Codan Console Mailer provides quick access to emails sent and received using Codan Chat and a commercial SMTP/POP3 client. The in-built Email composer enables you to quickly create an email, attach a file and send it or queue for sending later.


All data sent using Codan Chat can be transmitted in clear mode or encrypted with the inbuilt compression/encryption algorithm. When used in conjunction with a radios Privacy mode, text messages can
be sent securely from Codan Chat to a radio.
