Lyle, That's what I was looking for. I went to the hwnotes.rtf file to see the formatting.
I think it was in USB SAFE mode but will test it. Thanks, Lyle. 73, Jim N7US -----Original Message----- In cases like this, please check the firmware release notes for the radio. The info is often not found in the manual, which gets updated infrequently. I added the bolding... 73, Lyle KK7P *MCU 5.33 / DSP 2.86 / FPF 1.23, 8-3-2015* ... ** 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've lost track of the (menu?) setting that prevents the K3 or K3S > from going into TX when the attached computer is powered on. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
