Hi all: I have found a few more interesting problems with the Mac version of WSJT-X 1.80-rc2 r8069:
I am running a Mac laptop with OS X 10.12.6, and I installed the SiLabs USB serial port drivers. I am using an Icom IC-7300 via the USB cable, and after considerable tinkering, I think I have it to the point where the various levels are close to correct. Now as long as the computer and the screen don't go to sleep, WSPR decoding works fine. However, when I go to setup transmitting, things get odd: First of all, if I hit the Tune button, the transmitter will key, but there won't be any audio. If I go into Preferences -> Audio and set the Output Device to Built-in Output and then set it back to USB Audio Codec, then the transmitter will key and there will be audio at the radio's input. Now, once that is done, if I click on the Enable Tx button and then the Tx Next button, I will get a frame sent out during the next period. If I wait for another period or two, and press the Tx Next button, the transmitter will be keyed, but there won't be any audio again. I have to go back to preferences and "flip" the output device back to USB Audio Codec to get it to provide transmit audio again. Everything seems very flaky on the transmit audio side. Has anyone been able to get this kind of setup running reliably? A friend of mine, also using MacOS Sierra Version 10.12.6 and WSJT-X v1.8.0-rc2 r8069 but with an Icom IC-7410 reports the following: "I too experience the same problems with WSJT-X. I am hooking my Mac to my Icom 7410 with just a USB cable. The transmit audio is good for about 3 key-ups then it just goes to the computer speaker and NOT through the USB cable to the radio. I have no problem with either receive or transmit when running fldigi." "I’ve done some further troubleshooting and here’s what I have found. The problem does not appear to be related to Icom radios. It appears to be related to USB sound cards and the Mac version WSJT-X. To prove this I got out my SignaLink USB and connected it to the accessory jack on the back of my IC 7410. In WSJT-X configuration I selected NONE for radio and I selected VOX for PTT. I manually set the radio to the 20 meter frequency for FT8. I set the 7410 up so that data audio went in and out of the accessory jack for data. FT8 signals were received fine and an audio signal from the Mac/WSJT-X program was sent back through the USB cable to the radio and would key the transmitter with VOX for 3 or 4 times and then revert to the problem sending outbound (transmitter bound) audio to the iMac’s speaker (built-in output) when it was supposed to have sent it via USB to the SignaLink USB which would key the transmitter. I conclude the problem has to be in the software and not related to Icom or any other radios. The thing that I have not yet tried but I don’t see why it would work any better is to connect the radio or SignaLink USB to the Mac via a powered USB hub." "I happened to have a powered USB hub from another project so I tried it. The results are the same. The audio changes path after keying the transmitter 3 or 4 times. It’s what I figured would be the result of the experiment but I figured that I had to just give it a try anyway." Are there any references about how to build a "debug version" of WSJT-X to help figure out what's going on in cases like this?
