Codec 2 Over the Air

Some exciting developments this week with Codec 2 being used over the air for the first time!

Bruce, VE9QRP has written a script that allows Codec 2 calls over any IP network. He has tested it over the air using Laptop Wifi and is looking for people to contact him over the Internet.

Ben, VK6IC has tested Codec 2 on 145MHz using a home brew modem, all running on Windows (Ben’s work includes porting Codec 2 to Windows/MSVC). Ben had a contact with VK6UFO between Armadale and Ballajura (Western Australia), a distance of about 40 km. Ben has some off the air samples (including Speex at 8 kbit/s over the same channel) on his web site.

Sorin Cocorada has modified a Speex client to use Codec 2 and has been experimenting with simulated packet loss of up to 30%.

Fantastic work guys. It’s inspiring for me to see this level of interest in Codec 2. More discussion over on the Codec 2 Mailing list.

  1. Why not try Voice over CW, where your speech is transmitted as CW, and received by your software as CW , or speech and type ?
