[Elecraft] PTT KEY CONFIG setting volatile?

[n9tf at comcast.net]

Hi Gary, 
  
Firmware 5.33 was the improvement for this. See below in my message. (posted earlier this morning). If you have Unsafe mode toggled these settings will not default back to OFF-OFF. 
  
Even in the Safe mode, I have noticed the rig needs to have been powered down for more than a few seconds/minutes to reset to OFF-OFF. A test I ran this morning was to turn off rig "first" then power supply off and kept off for 5 minutes each, SAFE MODE and UNSAFE MODE, powered up the supply first then the K3S, and found in SAFE MODE the PTT-KEY had reset to OFF-OFF, but not in UNSAFE MODE. 
  
  


"* PTT/KEY USE WITH THE USB PORT IMPROVED: PC applications can activate PTT and KEY at the K3S via the USB port's RTS/DTR signals. However, initial setup of the rig's USB port by the PC may cause pulsed or continuous activation of the transmitter. This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB SAFE" or "UNSAFE". Exit the menu and turn the K3S off/on. Applications that use PTT-KEY via USB but never send commands may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S."

I just checked on my K3s and after the multiple off/on cycles, the 
PTT-KEY was and still remains set to RTS-DTR and I'm using the latest 
firmware.
