Running pi os, dw 1.6 and dw-start 1.3 on a pi 4 I can start dw-start.sh from a terminal window. When running from crontab, the following shows up in an email: /bin/sh: 1: Syntax error: Bad fd number

Have a look at FLARQ http://www.w1hkj.com/FlarqHelpFiles/ Danny K5CG

Keith,Are you asking me?Or are you just replting to the wrong part of the thread? I have never had an issue with PTT being stuck when using USB to TTL serial converters.I have used the DTech FTDI with

I use Gpredict to track the ISS and a couple of other satellites. My version doesn't seem to support the 99

Hmmm...what HAMLIB version are you using? Also, are you using feritte cores on your USB cables, rig properly grounded, etc?? If not, the RF from the rig can produce unpredictable operation. K

PTT /dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00C98A2F-if01-port0 does not key the radio. PTT

Also, since you're wanting to use this for ISS, Gpredict has a really nice feature for tracking lots of satellites, including the ISS.? I've used it to constantly adjust the downlink frequency to

Keith provided the specific line for the radio and how it should be configured for the virtual ports..I was working off physical serial port devices that I have used for PTT.? I have used different

Seems to be? usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00C98A2F-if01-port0 for tty/USB1. I have used /dev/serial/by-id before when I was using an IC-718. I don't use flrig because,

The only thing that should be using ttyUSB1 or 0 is whatever ham software I am running at the time. They are virtual ports generated by having the 991a plugged in to the USB port. Thanks

. . . PTT RIG 135 /dev/serial/by-id/usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_00A06B06-if00-port0 . . . Works. (check your port ID on your system and change if needed). Just

Are you using ttyUSB1 for anything other than PTT? If you have ttyUSB1 set to hardware flow control, that may cause problems.I think you can do this with the stty app.You can check the settings with

Thank you Robert. PTT /dev/ttyUSB1 RTS ... now keys the radio on startup of direwolf, but doesn't unkey. PTT /dev/ttyUSB1 -RTS ... also does not unkey.

If your working PTT port for (WSJT) is /dev/ttyUSB1 and it uses RTS, then the line in Direwolf.conf should read:????PTT /dev/ttyUSB1 RTS unless PTT is active low, then it would be:????PTT

I have been doing HF. I want to do VHF to communicate woth the ISS. WSJTX and fldigi? alway use U SB. I am most definitely NOT using flrig. fldigi is using hamlib. I believe WSJTX does too. PTT port

Hello Yishuai, There are three ways to interface with Direwolf: - pseudo serial port to connect into the Linux AX.25 stack - TCPKISS where you can write your own program to send KISS encoded packets

Hi David, Thanks for the reminder! I'll check my local coordinator's band plan to see which channels are for digital simplex. I'm stuck at physical layer i.e. didn't manage to convert any byte into

Hello Yishuai, There are lots of factors for sure including the robustness of the mode, noise floor of the frequency, width of the passband, the regional legality of symbols/sec of the transmitter,

Hi David, I currently have FM over VHF/UHF. I suppose the modulation and frequency limit the transmission rate. Are there other factors that are affected? I plan to start with RTTY, typing on one

When using Fldigi or WSJT-X, what mode is your radio in? What band are on you on? This can MATTER as some radios will have different PTT settings per mode (SSB, DATA, CW, etc), RF band (VHF, UHF, HF,
