Tom, I have been working almost all JT-65 over the past few months, but I have noticed a somewhat similar problem that can only be resolved by stopping and restarting PSDR 2.2.3 (Flex-5000 running under Win 7/32). The problem seems to cause receive issues as well. My problem normally takes much more that 30 minutes to rear its ugly head and I cannot seem to predict when it may occur.

After the radio has been turned on for some time the audio becomes very distorted. Sometimes, this takes the form of "motor-boating" and at other times it is more like a low freq hum on top of signals. This seems to happen after perhaps 30 minutes of on time. As soon as I stop PSDR and restart it via the "Start" button the problem disappears. I have experimented with all the combinations of buffer size and sample rate but to no avail. My computer is not the latest - about five years old - but seems to work OK in other respects with the radio. The CPU usage runs about 60% while using PSDR along with Explorer and Outlook running. It is a 3GHz dual core Pentium with 3 GB memory and running Windows 7. Probably a new computer in my future soon! Would appreciate any advice/hints as to a fix. Thanks. 73, Tom K1FR _______________________________________________ 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.flexradio.com/ Homepage: http://www.flexradio.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://kc.flexradio.com/ Homepage: http://www.flexradio.com/
