CAT Control
|
I have updated my uBitx to 4.3 as I would like to use CAT to interface with wsjt-x. I have been unable to find any information on how to set this up. I would appreciate hearing from someone who is using CAT with wsjt-x. I'm sure it's a simple procedure to set up, but I just can't find any instructions. Currently I'm using a usb sound card and a FTDI cable for PTT. ? 73, Dennis W7DRW |

1. Attach USB cable between ubitx and the computer. Attach two audio cables for mic and speaker between the radio and the comp. 2. Select FT817 as the rig on. Wsjtx. There is a test button on the settings panel to check if it works. 3. The wsjtx offers a choice of wsjtx frequencies. When you select one on wsjtx, the radio will show the changed frequency.? 4. Adjust the mic level on the computer until the signal meter on the wsjtx stops showing overload. Now, your screen will start displaying the signals.? 5. When transmitting, adjust the speaker volume on the computer to output slightly less than full output of the signal. You are done.? - f On Fri, 8 Jun 2018, 07:09 Dennis, <dennis@...> wrote:

HI,
I'm running wsjt-x with CAT control of my uBitx on a Raspberry Pi. I simply plugged into the USB port on the Nano from the Pi.? In my case the serial port was /dev/ttyUSB0 and I set the baud rate to 38,400. I set the radio to a Yaesu FT-817. Set the PPT Method to CAT. And mode to USB. I wired the tip and sleeve of the USB Audio adaptor headphone out to the tip and sleeve of the uBitx microphone jack. Wired the tip and sleeve of the USB Audio adaptor microphone in to the gnd and high pins of the uBitx volume control. The audio level into the wsjt-x is almost prefect, but I might add a couple of resistors to lower it a bit.? The transmit level adjustment on the wsjt-x control panel, in my case, works best a about -12db. I adjusted the transmit level by observing when the transmit power did not increases with increased "power" adjustment on the control panel slider. Then I backed off the power some. I also looked at the spectrum with my SDR and noticed when more spurs started to showed up, and backed off the power from there. The SDR and power measuring method both came up with about the same setting. If you don't have a power meter, luminous resistors (light bulbs) work great for the purpose. I used a couple of 28v, 0.07a models wired in series. I connected those as a dummy load to test with, before connecting to my antenna.? Tom, wb6b |

Hi Ashhar,
Doesn't work yet. Pulled FTDI cable and replaced it with the usb cable connected to the Arduino nano. Set up wsjt-x as instructed - baud rate at 38,400.Test button fails for every combination possible. Went to device manager for usb Serial and it says the drivers for this device not installed. I have it search automatically for the driver, but it can't find one. Not sure if this is the problem or not. I am using a usb sound card for audio in and out - that seems to work fine. The USB connection should be ok as I used it to upload the updated sketch. 73, Dennis W7DRW |

The Nano clone that comes mounted to the stock Raduino board

Show quoted text
that comes with the uBitx and Bitx40 from hfsignals has a CH340 chip. All the $3 Nano clones that folks buy to replace a fried Nano have the CH340 chip. The original Nano board used an FTDI chip, not the CH340 chip,? but nobody here coughs up the $20 for that board. Your FTDI cable should have worked, if connected properly to D0 and D1 for the UART connection. Must connect the cable's RXD to the Nano's TXD (D0), and the cable's TXD to the Nano's RXD (D1).? Must also have a ground connection from the cable, and some way to power up the Nano (radio turned on is sufficient). Under Windows, you need to install a CH340 driver to use the clone Nano's. Under Linux, the needed CH340 driver is usually already there. Under Mac OS-X, some drivers don't work, there are forum posts about this. On a? Rasberry Pi, it can be done, my guess is the driver is already there for the typical Linux os install. Jerry On Fri, Jun 8, 2018 at 01:36 am, Tom, wb6b wrote: Hi Dennis, |

I'm writing this in case anyone else is having trouble getting wsjt-x to interface with the uBitx via cat control. ? So, continuing in my quest to get cat control working in wsjt-x (I should say saga). I decided to try to use the win7 machine having just about given up on the win10 machine. I downloaded a new driver for the Arduino nano, made sure baud rates were set to 38,400 and was able to set up wsjt-x with ease. Cat control and ptt work without issue. So, back to the win10 machine ( a laptop I want to use with the uBitx for field day). I discovered that the last update forced upon me by Microsoft changed the mic settings. Changing the permissions to allow apps to have access to the mic seems to have fixed the problem. So, cat works great on both win7 and 10. Yahoo!!! |
