PowerSDR is not a digital mode program. There are no current plans to make it one since there are sooooooo many good programs available to operate digital modes. FLEXability is PowerSDR's first name. There is no need to reinvent the wheel.
"So, does one just pipe the audio bitstream to another program to do the decoding?" That is one way, and IMHO the preferred way to do it. You can also cobble together an external audio interface to a sound card in a computer in the traditional way you connect a transceiver to a computer for digital mode operation. In the first case, a third party program called VAC is used to create a virtual audio cable (VAC) between PowerSDR and the digital mode sound card program. In this configuration the AF between the two programs is kept entirely in the digital domain eliminating any noise or distortion introduced in the multiple A/D and D/A conversions. With VAC, PowerSDR "looks" like a soundcard to the digital mode program. See the following KB articles for more information: FAQ: What is VAC and What Does It Do? (http://kb.flex-radio.com/article.aspx?id=10475) HOWTO: How to Setup Virtual Audio Cable (VAC) 4.0x with PowerSDR (http://kb.flex-radio.com/article.aspx?id=10218) When you combine VAC with a virtual com port (vCom or Com0Com) to provide CAT support to the digital mode program, then you have a fully operational digital mode station. This will work for all digital mode programs except for the ones that require a specific sound card to work. In these cases, you will need to cobble together and external audio interface using the FLEX-5000 line in/line out (RCA connectors). -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian Lloyd Sent: Thursday, July 03, 2008 12:43 AM To: flexradio@flex-radio.biz Subject: [Flexradio] digital modes This is probably a silly question but I am wondering how one runs various digital modes with the Flex5000. I assumed that PowerSDR would provide the requisite codecs for various modes; e.g. psk31, mfsk, hellschreiber, etc.; but I didn't see it in the description. So, does one just pipe the audio bitstream to another program to do the decoding? -- 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/ _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
