Program version: 1.9.1 r8747
Operating system: Windows 10 Pro, 10.0.17134 Build 17134
Concise description of the problem: WSJT-X will place my Icom IC-7300 into 
transmit mode but will not transmit any data. Antenna connection is good and 
properly adjusted for low SWR. No data is transmitted on any band.
Exact sequence of steps required to reproduce the problem: Double-click on a 
FT-8 or JT-65 station received. BTW, the program is receiving beautifully. No 
issues. Try to contact the station. IC-7300 goes into transmit mode, but 
waterfall display shows nothing being transmitted, just a carrier. I have yet 
to make a contact, even with the strongest stations. I have checked the driver 
settings. The driver was downloaded from Icom prior to connecting the radio to 
the computer.
Driver is Silicon Labs CP210x USB to UART Bridge. On my system, it happens to 
be on COM5.  Port settings are 9600 baud, 8 data bits, no parity, 1 stop bit, 
no flow control.
Program settings are: Rig: IC-7300, CAT Control Serial Port: COM5, Baud Rate: 
9600, Data bits: 8, Stop bits: 1, Handshake: None, No DTR or RTS, PTT Method: 
CAT (COM5), Mode: None, Split Operation: None.
Test CAT: Green
Test PTT: Red
Audio Input: Microphone (USB Audio CODEC), Audio Output: Speakers (USB Audio 
Codec)
All other settings have been configured for callsign, grid square information, 
etc.
Radio settings:
CONNECTORS: ACC/USB Output Select: AF
ACC/USB AF Output Level: 40%
ACC/USB AF SQL: OFF (open)
ACC/USB AF Beep/Speech… Output: OFF
ACC/USB IF Output Level: 50%
ACC MOD Level: 50%
USB MOD Level: 40%
DATA OFF MODE: MIC,ACC
DATA MOD: USB
USB Serial Function: CI-V
USB SEND: OFF
USB Keying (CW): OFF
USB Keying (RTTY): OFF

CI-V Baud Rate: 9600
CI-V Address: 94h
CI-V Transceive: ON
CI-V USG - REMOTE Transceive Address: 00h
CI-V Output (for ANT): OFF
CI-V USB Port: Link to [REMOTE]
CI-V USB Baud Rate: 9600
CI-V USB Echo Back: ON

Again, everything in the program appears to be functioning normally except no 
data is being transmitted, but the transmitter is properly going into transmit 
mode, and the Test PTT test button is red and not green.

Thank you for your help. I have been trying to figure this out by going to a 
variety of Internet sources, but without any luck. Also, your Yahoo support 
group appears to be non-existent. I tried sending this issue to them in an 
e-mail, but it was returned as undeliverable.
