Set up: FT-450D,  long wire off center fed, 100 watts, no rig control, Signalink USB interface.

I have used WSJTX for over 1 year with no problems until a few months ago. I have set up

the Signalink according to Tigertronics latest instructions at least 6 times, which did not help.


Problem 1: Unable to receive signals in RX window and waterfall. All settings appear to be correct

And WSJTX set for audio CODEC on input/output.

I can receive signals if I change the input from CODEC to “Realtec Array “


Problem 2: Changing input from CODEC to Realtec Array and copying calls I can click

on a call and the op comes back to me. When I receive his reply TX2 or TX3 shows it is replying

back to him but it is not keying the radio and the op gets no reply so I lose the call.


I also am unable to receive  using RTTY. But that is on hold. I think WSJTX and  RTTY  have a

audio problem but I can’t find it after looking for 3 months.


I have a problem getting to my station. I am a WW-2 Navy veteran and living in a Missouri

Veterans Home-Mexico (age 94). I live on the 1st floor and my station is on the 3rd floor. Due to

the virus  we are on a lockdown mode confined to our floor. I recently got permission to go to my

station 2 afternoons a week. It may take several days for me to reply to any information sent

to me. Any help appreciated.

Hi Dick,

using a SignaLink USB interface the USB Audio Codec devices are the correct devices to select for the WSJT-X "Settings->Audio" input and output devices. If you are not getting any indication of Rx audio input on the thermometer style meter at the bottom left of the WSJT-X main window; then something fundamental is wrong with your audio hook up. Check you connections between the SignaLink USB and your rig. Check you have the Rx level control turned up on the interface. Check you have the rig in USB-DATA mode. Check in the USB Audio Codec recording device properties in Windows that the master level control is set to 0 dB (right-click the slider and select decibels if it is not reading in dB). Check you have allowed WSJT-X to access microphones in the Windows Camera and Microphone Privacy settings.

Once you have Rx audio getting to WSJT-X then set the thermometer style indicator to 30 dB on quite band background noise using the Rx level control on the SignaLink USB interface. Then you can move on to setting up Tx audio.
