USB RTS
Locked
 
|
I have had my K3S about 6 months and working with WSJT and DX Lab have used it with serial data for radio control plus RTS PTT with USB audio. I have tried several times to convert to just USB alone but I am always stymied when choosing RTS for PTT. I can use USB for Data and Audio fine but it is when trying to choose RTS is where the problem arises. The radio goes into transmit when RTS is selected as PTT. I can select DTR for PTT and everything works good but normally by convention DTR is used in keying on CW. I have gone through the USB.SAFE and UNSAFE variations. I disconnected all data cables, USB, RS232 and ACC Plug and still when I select RTS for PTT the radio goes into transmit. I have tried that with SAFE and USB.SAFE set. Again DTR for PTT works fine. All revisions are loaded and USB is selected under RS232 setting. Any suggestions.

Mike,
I know it does not fix it, but why not use DTR for PTT - or for data modes, you can use VOX or better yet PTT via CAT command - just turn that on in your software application. A data mode software that I am familiar with have provision for PTT via CAT command and I think that is the cleanest solution. It sounds a bit like the RTS signal is 'stuck on' at the output of the internal USB to RS-232 adapter chip in your K3S. Consult with the Elecraft support and tech folks after the 1st of the year. They are running with only a skeleton staff until then. 73, Don W3FPR On 12/27/2018 8:58 AM, Mike Greenway wrote: > I have had my K3S about 6 months and working with WSJT and DX Lab have used it with serial data for radio control plus RTS PTT with USB audio.

Have you tried this? Go to CONFIG:PTT-KEY
It's on page 67 of my manual. 73, John N1JM -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

This may apply you:
PTT/KEY USE WITH THE USB PORT IMPROVED: Some PC applications can control PTT and KEY at the K3S via the RTS/DTR signals of the USB port. However, use of these signals may also allow the PC’s USB port initialization to unexpectedly activate transmit at the K3S. 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 have my K3s in USB.SAFE John N1JM -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
