  Hello,

  My problem is no output power, not for tune nor transmit.

  My set up is:

  MacBook Pro - Catalina 10.15.7

  IC 7300

  WSJT-x 2.0.1

  USB Audio CODEC - CP2102 USB to UART Bridge controller

  
  
• my settings are as follows (from GitHub)
• 
  
• 
  
• Serial Port: /dev/cu.SLAB_USBtoUAR
• Baud Rate: 115200
• Data Bits: Eight
• Stop Bits: Two
• Handshake: None
• Force Control Lines: (Leave both empty)
• PTT Method: CAT
• Mode: Data/PKT
• Split operation: Rig

WSJT-X Audio tab

• Input/Output set to the 7300's USB device

WSJT-X Waterfall + Main Window

• Bins/Pixel: 4
• Start: 200-300 Hz
• N Avg: 2
• Palette: Digipan or to taste
• Cumulative
• Flatten: unchecked
• Ref Spec: unchecked
• Spec 30%
• Sliders on default/center except upper-right adjust to taste, usually ~30%
• Pwr slider 100%

7300 rig settings

• Mode: USB-D
• Filter Bandwidth set to widest possible (3.6k), sharp falloff
• Function menu: AGC, NR, NB, Notch, Preamps, Vox, etc all turned off
• Display typically set to waterfall + Meter
• Set -> Connectors:
  • ACC/USB Output Select: AF
  • ACC/USB AF Output Level: 10-30% (adjust as needed for band, noise level)
  • ACC/USB AF SQL: Off (Open)
  • ACC/USB AF Beep: Off

  • USB Send/Keying: All Off except Inhibit Timer

Macos Settings

• Applications->Utilities->Audio Midi Setup->USB Audio Codec 1: Left/Right both set to approximately -9.0db, adjust as needed while monitoring ALC levels on the rig. ALC should be at about 1/2 to 3/4 while transmitting. Some experimentation and outside verification (Web SDRs?) needed to make sure you're not overdriving the audio.
• Silicon Labs CP210x USB to UART Bridge VCP Drivers installed: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

If indeed you're using WSJT-x 2.0.1, download the latest public release as there have been a myriad of updates.

G'day Earle,

Just a thought but in your Mac preferences does WSJT-X have microphone access? Mic access is part of Apples privacy/security settings and access needs to be granted for each app as required. Learnt this the hard way when updating the OS one time.

Not positive, but I would suggest reducing the attempted connection speed to 9600 or so. As long as it matches the rig. Most CAT systems don't run as fast as you're set for. (Disclaimer - I don't know about your rig)
