Locked New to me computer set up today
|
D Lawson
I picked up a new (to me) computer today and had some trouble getting WSJT to transmit. I finally figured out the volume was turned off. Once I turned it on it worked. HOWEVER... when I tried to play a YouTube video to see why my WSJT contacts were not appearing in my Ham Radio Deluxe log everything went crazy. It seems like is was trying to transmit and I panicked.
I guess if I want to watch a video I better disable WSJT. While we are at it any idea on the HD log problemt? Thanks David KEØIOU |

What happened was that you have WSJT-X using the same soundcard
as the computer does for sounds. We hear this happening all the
time with computer 'dings' and even movie soundtracks being
transmitted. On 1/15/2020 6:25 PM, D Lawson via

This is why it is better for some people to use a separate sound card device like a Signalink to operate digital modes, especially for people who use their computer for many other uses. We all have probably heard music, Windows sounds, voices, etc on the ham bands. Using a separate sound device can minimize or eliminate this from happening. It also simplifies audio settings for digital modes, as you can usually "set it and forget it".

It is also better not to use VOX on the rig but control the Tx from WSJTX.

I am using a Signalink, that is what is so puzzling. Thanks KEØIOU David

Make sure your PC sound card is the system default, NOT the Signalink. Also ensure only your digital mode software is set to use the Signalink. Other apps may be set incorrectly.

Run a PTT line and avoid VOX. You’ll be glad you did. George J Molnar Arlington, Virginia On Jan 16, 2020, at 8:10 AM, D Lawson via Groups.Io <dlee58@...> wrote:

Don't forget the "panic" shortcut key: ESC will stop TX, abort QSO, clear next-call queue. See 10.1.9 in the User Guide. Cheers, Kai, KE4PT On 1/15/2020 18:25, D Lawson via

Windows may have set it as default.

Some versions of windows will change the windows
default sound device to the last sound device plugged in/added.
Additionally, the default sound device may be reset when windows
does a ( twice a year) feature update.

The key is the first part of George's advice to use the PC sound card for system sounds and the USB sound card for computer sound to/from the radio. Also FWIW, the SignaLink is not a great audio interface, and other lower cost units are better. http://k9yc.com/USB_Interfaces.pdf 73, Jim K9YC |

Not the cheapest interface, but looks to have a good chip and isolation. Native Linux support, as well. https://www.tindie.com/products/hb9zhk/digilink-nano/#specs

Any signals, such as transmissions from an FT8 Fox (they typically Tx around 300Hz), down at the lower end of the audio spectrum would be completely swamped by the LF noise generated within the SL-USB and therefore would not be decodable by WSJT-X. The second image shows the spectrum from a cheap (approx $30) USB audio codec device sold under the name of Ugreen. The difference between its LF noise and that of the SL-USB is self-evident. The third image shows the spectrum from a G4ZLP DigiMaster DataLink device; this is functionally equivalent to an SL-USB but as can be seen the LF performance of the G4ZLP device is far superior to that of the SL-USB. The G4ZLP device is also significantly cheaper than an SL-USB... Given this evidence, I can't see why anyone would consider using an SL-USB when even a much cheaper USB audio codec 'dongle' gives significantly better LF performance, and the G4ZLP device provides not only much better performance at lower cost but also equivalent functionality. -- Martin G0HDB |

Try XGGCOMMS.com ... interfaces for Yaesu, ICOM, and Kenwood.
Very reasonable. On 1/16/2020 10:47 PM, David wrote:
