flex control

Joe Sartori

sometimes tuning doesn't work.  it may work for a few kc but then I'm spinning it and it doesn't move...  any ideas?

You have it enabled under the settings in SmartSDR, right?
Are you connected to the PC via a USB hub?

Joe,  you may have a conflict of com ports.  this happens sometimes with flex control.  try adjusting the com port for your flex control to a different port.  use a high number, say like com 55, something that is well out of range of the others.  This has worked in the past for some with this issue.

This sounds more like an issue with the USB port not keeping up (https://helpdesk.flexradio.com/hc/en-us/articles/202118458-How-to-Mitigate-FlexControl-Latency) or a shaft encoder issue.

well I changed com ports and buffers seems the same ….

Check the set **** on the knob. I had the same problem.  Rich  W3OT

Thanks for the tip! I never realized there was a setscrew for the knob and that was my problem!

Same issue but nothing to do with the setscrew.  Every so often the FC just stops responding for a few seconds to maybe 10 seconds.  There is nothing obvious in task manager details, CPU is at around 22 - 35% depending on what else is running.

It seems to occur randomly, not very often.  Mostly I use the FC when working contests and S&P, and of course, it will stop responding.  It happens when only SSDR is running as well as when DXlab and DAX, CAT running.  

I have changed com ports, buffers, etc yet it still stops responding.  It has happened for years over different SSDR versions.  I've read the link Tim referenced.  I'm going to do it once more. 

I think it has to do with port data not being captured and passed on to SSDR; no evidence though.
