I have an occasional audio drop on my K3 when closing my logging program - Log4OM. The problem is an annoyance more than anything, but is still frustrating. There is also another OM who is experiencing the same audio drop as I do with his K3S. The audio drop can easily be reversed by simply tapping the XFIL key or by only slightly moving the shift or width knobs. By doing that the audio pops right back up. I can also reload the Log4OM application and click on a cluster spot (maybe even same station) and the audio will pop back up.
I have spent extensive effort with the programmers of Log4OM and the developer of the OmniRig application used to send the band, frequency commands between Log4OM and the K3. I've captured many debugging files and trace files trying to come up with item that may be causing the audio drop. So far to no avail. I've worked extensively with Wayne and he has provided me with early Beta FW versions in attempts to isolate the problem. He is tending to think it is related to flash read errors, but we still have not hit on the key. My K3 is s/n: 9013 and was assembled in May-2015. Since that time I've added a number of upgrades and one included the KIO3B interface. I installed the KIO3B option in June-2016. I have been able to isolate the audio drop to a change in the K3 Firmware. The audio drops started to appear with FW V5.50 that I installed in July-2016. I've tried other FW Beta releases and am currently using FW V5.56. Sometimes the audio drop won't occur for a day or two and other times it happens each and every time I close the Log4OM application. Doesn't seem to matter if I'm using the USB or serial I/O for communications. What does help isolate the problem is that when I revert back to FW V5.38 the audio drop just does not occur at all when closing the Log4OM application. Certainly seems to be some weird anomaly in the FW and maybe there is a timing issue with commands coming out of Log4OM and OmniRig, but just have not been able to ID it yet. As I've noted Wayne has been working hard to help out, but we're still both a tad stumped. I'm just tossing this out looking for some out of the box thoughts for something I'm completely missing in trying to trouble-shoot. Again, this is not a huge problem rather just an annoyance, but it still bugs the heck out of me. 73, Nolan Kienitz - KI5IO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
