Hi Greg.

I have also noticed that FT4, while being less sensitive, is great for combating QSB due to its speed.

I have seen more FT4 activity on 40, 30 & 20 FT4, but, like you, I wish there was more.

Hi Alain,

on the IC-9700 the AF output level over the USB audio connection is controlled by the rig menu setting "SET->Connectors->USB AF/IF Output->AF Output Level". It is best to have all other level controls in digital Rx audio path at 0dB FS, e.g. the PC sound card input level (right-click the master level control in the sound card recording device properties to select a dB scale).

Bonjour cher OM,

 merci pour votre réponse, j'ai  changé de version de wsjt-x ,pour  la 2.1.2  la il n'y a plus  de curseur pour le reglage du niveau je pensais a une astuce wsjtx , avant de toucher au niveau de la carte son ce que j'ai fais maintenant , j'en ai dailleurs profité pour régler l'échantillonage a 48k comme conseillé dans wsjt-x.

encore merci,

cordiales 73s,

If you're operating your receiver with the AGC turned off, as advised in the WSJT-X user documentation ("It is usually best to turn AGC off or reduce the RF gain control to minimize AGC action."), then you need to make absolutely certain that you're not suffering from overload somewhere along the receiver chain that's causing the audio output from the receiver to become distorted.  A quick listen to the audio should give you a good feel for the quality of the signal going into WSJT-X; any distortion will cause havoc with the signal processing and consequentially an absence of decodes. 

As per the above quote from the User Guide, if you've turned the AGC off then it's necessary either to bring in sufficient RF front-end attenuation and/or to turn the receiver's RF gain control down until the audio sounds clean on even the strongest signals; it might then be necessary to increase the audio output level from the receiver and/or to adjust the computer's 'recording' audio level control to enable the recommended reading of 30dB on the WSJT-X 'thermometer' to be achieved when receiving only band noise.

Ryan,

the WSJT-X call "Lookup" button searches in previously stored entries, saved by the "Add" button. The retrieved data is the grid square. The functionality is designed for EME and other VHF, UHF, or microwave modes where grid squares can be critical to making a QSO. Particularly with EME, the grid square is needed to calculate the Doppler shift between yourself and a DX station. The function is not intended to do any remote lookup of information from web services etc..

locked Re: WSJTX with Softrock

Paul Coddington
 

Thanks to those of you who replied.
 
I have investigated this option in HDSDR and using this you can solve the problem in a somewhat bizarre way.
As you probably know when you swop the Rx I/Q channels in HDSDR you invert the spectrum around the LO frequency (essentially you change the positive and negative frequencies).
This means you need to treat any incoming USB signal as LSB, and when you do this you can make the wsjtx – HDSDR – Softrock combination work for both Rx and TX.
But it does look odd on the screen.
Also I can not understand why this has changed in going from W7 to W10.
 
Thanks again

Hi I am hoping someone can help.
 
I have been running wsjtx with various modes using the following rig combination.
 
wsjtx ---> HDSDR ---> softrock The link between wsjtx uses VAC cables for audio and CAT to HDSDR for rig control.
 
This combination worked fine for many years (since 2016) on a PC running W7 with many 100s of contacts.
Unfortunately having recently replaced my W7 PC with one running W10 it no longer works.
I have traced the problem to the fact that somewhere in the chain the allocation of the I/Q signals to the L/R audio channels gets swopped.
 
Now the reason for asking help from this group is that I do not see the same problem when going from W7 to W10 with other software combinations
eg Powersdr v2.4.4, fldigi ---> quisk
 
I know that this is an unusual setup but I would be interested if anyone else using a similar system has experienced problems.

Hi Paul,

in HDSDR on the Options menu (F7) you can select swapped I and Q channel assignments for Rx for sound card I/Q data.
