One thing I can't find.. Is possible to generate a PL or sub-audible tone to access a ten or six meter FM repeater?
Not yet from within PowerSDR. You can do it with a third party application and VAC. When the FLX-VU5K module is released later this spring, one of the software features will be the addition of CTCSS tones to PowerSDR. It may not be in the initial release of PowerSDR that supports the FLEX-VU5K, but since I want to work some LEOs that require tones to open them up, you can bet I'll be doing my best to influence the development schedule (BTW, I have little influence in that area. Greg keeps sending me to the PowerSDR product manager, Helen Waite.

You've been a great help. I think I've got everything straightened out now. Yes, I have a lot to learn about SDR and I'm eager to. I'll be sure to have many more questions to post on this forum. I've been using a Yaesu FT-847 for the past eight years since I got my license. The Flex makes the 847 seem like a regenerative receiver or something. I was listening to the big contest this weekend and holy cow can the Flex separate the close together signals! One thing I can't find..

Do not set the AGC to fixed in digi modes. PowerSDR has the most advanced dual attack AGC algorithm of any radio. The algorithm was developed based on Phil's paper on the subject http://support.flex-radio.com/Downloads.aspx?id=98 Refer to the second paragraph in section 1.1 regarding fixed AGC and distortion with direct conversion receivers, of which the FLEX-x000 is one. What ever you learned regarding setup on a traditional, legacy type radio is not necessarily how it works with a SDR. Case in point. The s-meter always reads the actual signal power integrated in the RX passband no matter what the AGC-T settings are set for. My Icom's s-meter changes with changes in RF gain. The AF control does not have anything to do with gain levels when running in DIGx modes using the VAC channels. _______________________________________________ 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://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
