(tr)uSDX - Setup for DigiModes and CAT Control

[@pnowikow]

I watch a lot of these videos and I can't wait to buy one of these little guys.

[@vorteco7692]

I have the exact same settings. I have the driver installed from your web page. My PC recognizes the device under ports COM CH340. When I push "Test CAT" the radio clicks, powers off and back on. CAT test fails. What am I doing wrong? I've tried multiple PCs. Multiple cables. Multiple USB hubs. COM 5 is the truSDX and COM 3 is my digirig sound card on my system.

[@siehauf]

Any luck? I'm having same problem.

[@siehauf]

I got it working. Had to set COM rate to 115200 in Device Manager and in the program I was using (JS8Call).

[@ismiregalichkochdasjetztso3232]

I'd find it very convenient if it was possible to disable PTT in software, so I wouldn't need a special cable. But such a nice little radio, thanks for all!

[@jgaffney6]

Thank You I did purchase the radio and it is a work of art very professional and i enjoy you videos Jim K4YNA

Cannot wait to get on the air using FT8!

[@Heniek]

Do you not use any hardware interface and just connect both jack cables directly to the computer?

[@dl2man]

As mentioned in the Video: directly connected ! Dangerous, but: No Risk, no fun ! 73 Manuel; DL2MAN

[@dougtaylor7724]

Just found your channel. Great stuff! Subbed

[@southernexposure123]

Thank you for the video. I just got my assembled trusdx a few minutes ago and trying to get started. ALL my computer control panel settings are at maximum for my speaker audio volume according to several videos telling how to get high volume audio from my computer. Although there's a lot of videos I can hear even when I turn down the video volume control I still can't hear this video. Ooooohhhhh All the advertisements attached your video I can hear really good. Is there a video on the trusdx that's recorded a lot louder? Thank you.

[@dl2man]

Try this for comparison: kzbin.info/www/bejne/hqrHc2OYaJx8mNE I started using external microphone with the "NVIS" Video... 73 Manuel; DL2MAN

[@RobertEngel-v7d]

For the transceiver settings is it just SSB and USB for digital modes?

[@Inkling777]

There are adapters that let users get the mike/speaker from an iPhone. Is there any digital-mode software that works with iPhones (or Android phones) and gives CAT plus the digital modes. The combination would be far more portable than any system involving a laptop. And echoing that tiny (tru)SDX screen on an iPhone would be marvelous for those of us with aging eyes.

Vielen Dank für das Video und für die Entwicklung des (tr)uSDX. Ich habe seid Wochen probiert den (tr)uSDX an meinem Linux-System ans laufen zu bekommen, allerdings nur mit Problemen. Die CAT Steuerung hat sich nicht stabil aufgebaut. Beim meinem Windows-System war es kein Problem. Durch dein Video ist mir aufgefallen das beim Linuxrecher die Felder „Force Control Lines“ nicht ausgefüllt waren. Nachdem ich diese richtig eingestellt habe läuft es endlich Problemlos. Noch mal vielen Dank, ohne das Video hätte ich das wohl niemals gefunden. VY 73 de Peter; DL2PK

i've got comunication error with rig / connection rig is broken when connect my rig to ft8cn via CAT

[@Kd4jwf2024]

Team, just join the forum but I going to ask here, I had tried to follow the set up as you describe but it does not want to give me the green light ....it does key the radio when try to test but never goes green and give me an error about Omni-rig or timed.out while connecting to radio....it does work perfect with Winlink settings but not for JT8 or JS8Call.....what I am missing???? Using windows laptop

[@dl2man]

Unfortunately I´m not an expert in CAT Communication. I have no clue why some apps work and some not. But if you use the search function in my forum, you can find a lot about CAT from way more skilled people then me. 73 Manuel; DL2MAN

Hello I purchased ur tr usdx assembled from the Chinese vendor and noticed the tranceiver has a noticeable hum on 20 meters he sent me a new top board . I installed it and it still has a hum . Quite loud . Do not know what to do next. Any advice ? I would love to that great tranceiver for backpacking . Thanks. Rodney. Ki6pxv

[@dangermandave67]

In Direwolf, the options to use PTT are RTS or DTR. Would these work with the signals that (tr)uSDX is sending to the COM port? Which one would I use? Or should I just use VOX? What I'm trying to do is operate APRS on the 30m band. I don't know whether I can do that successfully with only 5w, but let's see. I was in a discussion with the operator of an I-gate in Seattle who received my APRS signals sent from Utah with a 10w radio and he said that they were pretty weak. Maybe I'm going to have to use Robust Packet.

[@dl2man]

I have no clue, what direwolf is, but CW can be triggered by RTS (independent from key line). For PTT (on any other mode but CW) you should use CAT Command. 73 Manuel; DL2MAN

[@dangermandave67]

@@dl2man Direwolf is an APRS software modem. It sends and decodes AX.25 packets through a computer sound card. It can use VOX, but the radio needs to have a fast circuit for this. PTT is best. 73 de K7DMJ

[@WA4NDR]

@@dangermandave67 check the direwolf user manual, section 9.2.9.4 for setting up PTT using hamlib. hamlib acts as a middleman to send the CAT commands to the radio and direwolf will use it instead. Looks like the model ID for a Kenwood TS-480 is 2028. Hope that helps.

Hello Manuel, Thank you for a good device and video. I have a question: What if I use standard unmodified aux cable? Will there be any problem getting (tr)uSDX on the air? I've seen couple other videos recently and people there are using aux cables which look unmodified, can you confirm this opportunity? I am going to use this Tx with FT8cn on android.

Thank You Manuel! Will there be an opportunity to illustrate how to use FLDIGI for Other digital modes… RTTY, PSK, CW etc… Will there be Mode and filter CAT commands available? 73

[@dl2man]

Hi Frank, Setting up FLDigi follows the same pattern as shown in this Video. In Fact I´m running that with (tr)uSDX anyway. Don´t know if a new Video will be made for that. Mode changes already work (MD cmd), and yes a subset of DSP filters can be added (SH/SL cmd). But I cannot give any timing for that. 73 Manuel; DL2MAN

I cant get cat to work I have installed driver ch340 but it does not recognize the (tr)uSDX when plugged in. Can anyone suggest how to fix this. Receiving all sorts of signals on WSJX. Would like to be able to complete setup!

[@dl2man]

Sometimes Windows block comports and hides it. In your device manager set it to "show hidden devices" and see if there´s any hidden com ports. If so: Uninstall them, restart your computer and try again. Make sure, you use only the CH340 driver linked on my Firmware page. We also saw problems with newer/older Versions. If you still can´t solve it, join my forum.dl2man.de and post your issue in the troubleshooting section. I´m sure you´ll get a lot of suggestions. 73 Manuel; DL2MAN
