APF Button stops working...Kills all signals when activated.

Ken - NM9P

When switching from band to band and mode to mode with one pan and 2 slices, I have had several occasions when the APF button stopped working, and actually killed all audio and all S-Meter readings on the slice flag.  Curious...

Close SSDR and reopen it and it works again.

I don't know if this is related to the previously reported AGC Sticking problem?

I had this occur today.  Activated APF and audio went dead.  Did you learn the cause of this behavior?

I have had it happen several times, but haven't been able to correlate any sequences that cause it. I am usually changing rapidly between frequencies using CAT via my logging program.

I will need some additional information related to how to cause this issue, as I can not reproduce it and it is difficult to investigate defects that we cannot reproduce.

I Will be away from the rig for a couple weeks. I Will run more tests when I return.

It seems to have happened when switching rapidly between CW, digi, and SSB when using narrow filters of 50 or 100 on CW and doing my typical DX/w1aw/p hunting on all modes

I notice that when this happens, the NB, NR & APF sliders all go to zero. When I click APF, all audio dies. I am directly connected to the desktop, no router, internet via wifi, running win 8.1 with an Intel i3 and 6 Gb RAM. Running latest SSDR release 1.2...

OK.  This sounds like an overflow issue with the APF filter.  I have entered this as a defect in the developer's bug tracker for additional investigation.
