Hi Richard

If I had this issue (and I don't), I would look more at the computer and seeing if your DPC's are increasing.

It sounds like it might be related to computer hardware (hard drive older than 3 years and in a constant state of repair - sadly, there is no reporting way to tell, but it is a real problem) or something else is consuming a lot of CPU time.  In short, you are likely I/O bound (IT Term).

Can you answer the following questions?

• DPC numbers?  this tool can help show that https://www.resplendence.com/latencymon
• Is Windows 32 bit or 64 bit?
• How much memory installed
• Look in windows and see if you 'swap' space is increasing.  Swap is used by the computer to make your computer look like it has much more memory that it really has.  It does this by moving programs in Memory (RAM) to your Harddrive when they are not in use.
• Is your Hard drive light on all the time?

Based on what you have said so far, with N1MM and SSDR running at the same time, your computer is running out of memory and then the retrieval of the WAV from the hard drive is very slow.

Those are all good numbers so that should eliminate that part of the problem for the moment.  Thanks for sharing.   I assume those screen shots are from when you were having the failure?

Here is what happens when you push F2 in N1MM

• N1MM receives the F2
• Decodes the command and gets the audio recording from the hard drive 
• Asserts PTT via SmartSDR CAT (either PTT or CAT command)
• Plays the Audio recording on the TX Line in DAX
• Recording completes
• Radio unkeys

Can you test with K9DUR's voice keyer at all and see if you can recreate it?  http://k9dur.info/voice_keyer.html.  I'm not sure where to go if it works or fails.

Do think that maybe something got changed in the 6600M by mistake causing this delay and buildup?
