Hi all, While Andrew Smith (VK6PDQ/VK6AS) is on holiday I have his SM1000 to play with. Nice piece of kit. (I added 4 feet to it, makes it stay on the bench - http://www.bunnings.com.au/madico-surface-protection-8mm-vinyl-rnd-clr-23260cf_p3979381 )
For an episode* of "What use is an F-call?" - I want to achieve the following: - Record some audio that has been transcoded using CODEC2, so that listeners get a sense of the difference between analogue and digital audio. - Record some digital - non-decoded - audio, so listeners can hear what CODEC2 sounds like on-air. - Record some digital - non-decoded - audio and put it as a "sub-audible" signal underneath some normal analogue audio, so listeners get two information streams for the price of one. I am unclear what audio levels come and go from the SM1000 and I don't want to blow up either ports on the unit or my computer. I have installed FreeDV onto a Debian Wheezy virtual machine. (Running on a Mac, so no "microphone port", just a "line level port". I also have a Heil headset and an audio mixer. I've been trolling the documentation, the wiki and other information, but I'm not clear on how to achieve this electrically. Any pointers would be gratefully accepted. (And when I achieve it, I'll document it, so I won't forget how to do it later ;-) I also came across instructions to compile CODEC2 from source, but I cannot seem to checkout from the repository. Not sure if that is because of the SF outage [ http://sourceforge.net/blog/sourceforge-infrastructure-and-service-restoration-update-for-722/], or because of a configuration problem at my end. Look forward to hearing from you. * Technically, "What use is an F-call?" no longer exists. As of a few months ago it's now called "Foundations of Amateur Radio", but the national news is about a year behind, so nationally this won't be heard for a little while. -- Onno Benschop ()/)/)() ..ASCII for Onno.. |>>? ..EBCDIC for Onno.. --- -. -. --- ..Morse for Onno..
