It can be done. K9DUR build a VoiceKeyer around the concept. In the Wave form, there are options for TX and RX listed as pre and post processed audio. A recorded wave file is a post processed audio file. You can play your wave file back as long as the TX option is set for post-processed audio.
I believe you can also use the K9DUR VoiceKeyer for transmitting MP3 or they may have to be wave files too, which may be easier to deal with. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of bobt Sent: Tuesday, June 01, 2010 12:07 PM To: [email protected] Subject: [Flexradio] Wav files again Hi to the group, I've searched all of the archives with out an answer to my problem. I understand that received and recorded audio/If is stored as a Wav file, and have successfully recorded and retransmitted received signals. I now want to take an mp3 file (containing interview/music material from a bulletin ) and transmit this. The group that I work with (rag chew) some have extremely good receivers/spectrum analysers and the honor of flex and my 5000A is at stake for the best audio TX (only two of us in the country). I have a couple of choices..the (easy) route of an rca connector into the back of the flex, and the holy grail of a fully digital route. Naturally the digital route is one that interests me ! is this possible ? I have seen references that mention the wav files are the I and Q files or axis. Does that mean the stereo bit of the wav file contains two different signals. And so could not be created from an ordinary MP3 or Wav file. I am using the virtual audio connections with DM780 to transmit psk31 etc. so something should be possible. Has anyone done it yet or is there road block somewhere The South African regs permit transmission of music for "test" purposes and it seems a good way of sorting transmissions.when you get back a snatch of music that you have just sent it does make things clear about compression and overdriving.
