Help Needed: Audio Transmission Issue with WFVIEW Remote Control
Hello everyone,
I’m BG2CTX
I using the ICOM 7300 radio with WFVIEW for remote control and WSJT-X for FT8 decoding and transmission. My setup and basic configuration are as follows:
- Radio Connection: The ICOM 7300 is connected to a PC via a standard USB interface, with both USB drivers and sound card drivers installed.
- Software Configuration:
- Local PC (Server): Running WFVIEW, using the USB sound card for audio capture and transmission.
- Remote PC: Running WFVIEW for spectrum display, radio control, and audio monitoring.
The system used to work seamlessly, but recently, the remote PC has been unable to receive audio from the radio. Below is a detailed description of the problem and troubleshooting steps I’ve taken.
Issue Description
- Symptoms:
- Spectrum and Control Normal: The remote PC’s WFVIEW shows the spectrum display and can control the radio properly, indicating that network transmission and USB interface control are working fine.
- Audio Transmission Failed: The remote PC cannot receive or monitor the audio from the radio.
- Troubleshooting:
- USB Sound Card Hardware Verified:
- Using the Windows sound control panel to monitor the USB sound card’s recording input, I can hear the audio from the radio, confirming that the audio is successfully transmitted to the local PC.
- WSJT-X Error:
- WSJT-X connects to WFVIEW via the
EXTERNAL CONTROL
feature and can control the radio frequency, but it shows aSOUND CARD INPUT ERROR
, indicating that WSJT-X cannot decode audio from the sound card.
- WFVIEW Configuration Suspected:
- Based on previous experience, WSJT-X and WFVIEW should be able to use the USB sound card simultaneously without interference. However, this is not working now.
- Attempts to Resolve:
- Restarting the radio.
- Reinstalling the USB sound card driver.
- Checking audio device settings in both WFVIEW and Windows, but the issue persists.
Request for Help
It seems to be an audio transmission configuration issue. I am unsure whether it is due to Windows audio settings or WFVIEW settings, which may be preventing WFVIEW from properly capturing audio from the USB sound card.
