Re: [Flexradio] Band/ freq changes after shutoff
The short answer is that, it shouldn't matter if there is a long wait (several thousand microseconds) for a DPC to complete while PowerSDR is shutting down. The OS is what controls that. During the DPC, things are waiting gracefully. After the audio stream is stopped, the in-memory DB is written to the XML DB when PowerSDR shuts down. -Tim --- Tim Ellison, W4TME Product Management, Sales & Support FlexRadio Systems^(TM) 4616 W Howard Ln Ste 1-150 Austin, TX 78728 Phone: 512-535-4713 Ext. 223 Email: t...@flexradio.com <mailto:t...@flexradio.com> Web: www.flexradio.com <http://www.flexradio.com> logo /Tune In Excitement^(TM) PowerSDR^(TM) is a trademark of FlexRadio Systems/ On 10/16/2011 4:08 PM, W1AEX - Rob wrote: Hi Scott, A few weeks ago I noticed something unusual when stopping PowerSDR and shutting it down that might be related.

Re: [Flexradio] Band/ freq changes after shutoff
I do exactly the same procedure, except I normally press the START button to stop the application, then I close the application, and then I power off the 5000A and then shut off the 12V power supply. I just had it happen this morning. When I closed PowerSDR early this morning, the radio was on 75M. When I started the application later in the day, it was on 40M which is where I was using it on Friday. After seeing that, I shut it down and started it back up several times and each time PowerSDR came back up to where I left it. Go figure. I have learned to live with it as a quirk because the band hopping happens completely at random. While it may be annoying, to quote an old timer friend of mine, "it ain't the end of the world." de Rick, KN3C -Original Message- From: Lee Mushel [mailto:herbe...@centurytel.net] Sent: Saturday, October 15, 2011 10:41 To: Paul Delaney - K6HR; k8...@aol.com; k...@arrl.net; scott.wa4...@gmail.com; flexradio@flex-radio.biz Subject: Re: [Flexradio] Band/ freq changes after shutoff Years of both 3000 and 5000A and never had a "frequency change" with either and with all the PowerSDR changes.
