Hello from Australia. My built radio purchased through an approved supplier arrived today! Thank you very much for building a radio at a price point that allows me to listen, attempt to establish contacts and learn about the hobby. VK3FSMB
Absolutely fantastic. Well done, Manuel and team. You all have and practice the true spirit of ham radio, a hobby I have been very happy with and active in for over 50 years. Thank you!
You build it, like you designed it! Marvelous, beautiful indeed! My compliments Manuel. I can’t wait until my group buy team is ready. 73, Robbert, PA3AP.
Perfect!!! I bought a kit for high bands and classic bands, so I really only needed the RF board part of this video, and man, you made it look easy! So I now have the confidence to build the other two RF boards so that I can have all bands! Great work, and so glad that you took the time to walk us through this whole process, you thought of everything!!!
Very well thought-out design. It's fun to watch the video and makes you want to build.
Thanks, You made the kit build look doable even for us large handed hams.
この動画を見て (tr)uSDXキットを組立しました
各バンドのフィルタ調整もして完璧に動作しています
とても参考になりました
ありがとうございます！
from Japan
Working now, after correcting some mistakes (properly removing insulation from coils; mounting both 13-pin connectors correctly)! Looking forward to meeting you on the band(s). FB!
You sir are truly amazing, du bist sau clever ;-) I will make one of these soon, along with the rest of my radio club here in the uk. Thank you so much.
Congratulations Manuel! Well done! 👏🏻👏🏻
Wow, such an amazing work! Congratulations! I am now jumping to the forum to search for a group buy!
Where did you obtain the housing?
The housing is locally 3d printed
My old electronic teacher used to go crazy cutting pins after soldering, as it could cause shock/damage to the components. This video just brings back those memories, definitely interested in this project...
thanks for nice info. I have uSDX, and love it
Put a dot of solder on that iron tip and those SMT caps will slide right off immediately. I learned long ago that component removal required substantially MORE solder than the assembly did.
A solder sucker will not only remove most of the solder, but the capacitor itself.
Artistry! Thank you!!
Excellent ..... Try a small amount of double sided tape for the speaker and then a " donut" of medium density ( or whatever you have handy) foam around the speaker and microphone to improve the audio quality.
Amazing project
Das war gut den Zusammenbau mal gesehen zu haben. Vielen Dank dafür! Liebe Grüße, Matthias DL1NDG
Danke für das Lob!
@@dl2man Ja, das ist wirklich wichtig. Das finde ich echt toll.
Nun könnte man hier immer wieder nach-schauen.
Liebe Grüße
Matthias
Thank you !
Really nice…
I'm currently building mine, started last night, and finished the main board. Only problem I had was the 2mm bolts & nuts for the oled, I changed the nuts for some I had in stock, they were fine.
Great kit! Only bummer is that it doesn't come with the extra header pins for the oled.
👍👍👍👍
There is also x2 smd devices to do on reverse of rf board right? Hope so, I just bought 50 of them!
The 2 smt devices on the backside of the Rf board are footprints for alternative RF MOSFETs. They can be placed INSTEAD BS170s but then filters need to be adjusted. Those footprints are for future applications only.
WELL DONE The User Indonesia Amateur Radio Support of IT BEST 73
I just discovered! How do I get a complete kit? Yes, I need a leg up ;)
fantastic. I seem to have blown an/the output transistors, are they still using the bs170s?
Low Bands Version uses 3xBS170, Classical and High Bands using 1x FDT86256. All documented on dl2man.de
Awesome! Why did you disabled the internal charge pump of the oled?
Because it created audible noise. OLEDs are very noisy, and this is the way to get around that.
Hi, the pin header I have that connects the 2 boards are different than what you have in the video. I don’t have longer pins on one side compared to the other. I’ve tried moving the spacer with no luck. It won’t budge. Is this ok to solder in? Also, the break away pin headers for the OLED. Where are those? They don’t seem to be with the kit. Thanks for any help! Mark - W7MMG
คุณช่วยแสดงวิธีพัน T1,T2 ให้ดูแบบชัดเจนได้มั๊ย Thanks you.

Hi Manuel
Did you ever do the programming video ? I can only find a very old video before usb…
Did you see this ? ua-cam.com/video/K_oj9025o9M/v-deo.html
I would like to change the microphone that comes with the radio for something better, would you mind telling me what is the impedance of the mic, so I can try to get a better mic. The one constant comments I get on the qso's is that my sound is very low.
This is the one I use. Please check Data Sheet for the Numbers you need: datasheet.lcsc.com/lcsc/1912111437_INGHAi-GMI4527P-2C-40db_C233329.pdf
May I ask what mode the nanoVNA is set to when you are adjusting the toroids?
I have a special Video about Tuning the FIlters: ua-cam.com/video/qN7hHsvcNMM/v-deo.html
Hi, I'm JJ0TUC. I have assembled uSDX. However, I am having problems with "! V3.3=1V" and the screen does not proceed. the version of the PCB is JA2GQP with 74HC4053, Arduino NANO and the version of the firmware is 1.02w. Can someone please tell me how to fix this problem?
22:15 Do you also have a list of the needed inductance values? I all manuals I only found how many turns but not how much µH What be nice to have and check with the LCR meter
Hi, Inductance Value is dependent of the frequency, you´re measuring it with.... So probably less accurate than the amount of windings. But if you look at the dl2man.de/2-trusdx-assembly/ page, you´ll find the theoretical values for 3xBS170 in the "alternative Bands" Section.
@@dl2man Thank you, my EE DE-5000 has several options for frequencies. I'll check your link out
Danke! Manuel...do you have STL files to share for the enclosure you 3d printed?
Tnx de Arnie W8DU
Never mind...I found them on your website. Thank you again!
Hello all,
First of all Kudos to DL2MAN and associates.
now the real hurdle: I was able to buy 5 sets of PCB with some components on them.
Currently I find it hard to source the following components:
SI5351A-B-GT
TCA9555PWR
IRLML2060TRPBF
any equivalent is well received for SI5351A-B-GT the back order is around 02.2023! which is kind of disappointing
Why didn´t you follow my advise on my page and have the MS5351 places instead by JLC-PCB ? Si5351 is out for almost half a year now, and you can only buy MS5351 from China or buy Si5451 evaluation Boards and try to unsolder them.... TCA9555 can be substituted by PCA9555 or CAT9555YI and IRLML2060 is not needed on the (tr)uSDX. Please read my instructions and ask in my forum if something is not clear: forum.dl2man.de
Hello Manuel, I am assembling a kits (tr) SDX. In the video you indicate that the transformers T1 and T2 are the same (P7 t. / S1 t.). In the specification sheet that came with the kits it indicates for T2 P 21turns /S 3 turns. ? Which one is correct? Thanks for your time.
Please have a look at this: forum.dl2man.de/viewtopic.php?t=395
@@dl2man Thanks Manuel! That was very helpful!
Wish you had zoomed in the camera when you soldered.
You are absolutely right about his. In this Video: ua-cam.com/video/hLCFsNNDZUg/v-deo.html I show more details, especially regarding the OLED Modification.
Donde compro su trabajo terminado? tienes algun link?
Ja schön, dass Du auf ein englischsprachiges Video auf spanisch antwortest, so dass ich einen Übersetzer brauche... Lass miich Dir die gleiche Freude bereiten, und in meiner Muttersprache antworten: Ja, auf dl2man.de findest Du alle Informationen, die Du brauchst.
I am assembling this kit now... my OLED does not have a U2 spot for the jumper do you know which spot to solder the wire? I was guessing O1 because it looks sort of like it...
Whatever on the OLED is connected to VCC Pin can be used instead of U2. But Watch out for the right display ! There are Versions where VCC and GMD are swapped ! 73 Manuel; DL2MAN
Thank you for taking time to respond. I am having fun building your kit. I took a photo of the OLED with the jumper it was Q1 to C6 if you would like I can send it to you in case anyone else is wondering.😀@@dl2man
Nice hobbie that's great i like that
Manuel....have you done the programming video yet? I would sure appreciate it!
73 de Arnie W8DU
No, not yet. But the written instructions are available: dl2man.de/3b-trusdx-firmware/
How and where do I buy or order this nice project build ??? I am located in Denmark (EU).
Gibt es ein Diagramm zum Hinzufügen von SWR und Wattmeter zu usdx?
Nein, das wird nicht möglich sein, da beim uSDX Ein- und Ausgänge dafür fehlen. Die Software ist auch nicht kompatibel.
Gibt es das Gerät eigentlich auch mit RTTY-Decoder?
Nein, dafür haben wir keinen Platz auf dem kleinen 8 Bit Microcontroller. Über PC aber jederzeit möglich
Hi Manuel, why don't you do something for those of us who want to buy it and we can't find groups, a complete kit with a certain part number where all the necessary material is included. It would be less complicated for those of us whose English is not so fluent, everything you need including pcb case, components and the pre-assembled smd as what you show in the video
Thanks for your comment. Answer is: Because I´m a developer, not a seller. I have limited time and resources, so I´ll leave the logistics to someone else. There will be official and approved Kit and even Radio Suppliers in the near future. Subsribe to my channel and hit the bell, to get notified about any news.
Kann das Ding auch auf 45m ( 6.675 MHz ) senden ????
Theoretisch ja, praktisch müsstest Du das entsprechende 40m Filter dafür abstimmen.
Are there step by step printed assembly instructions?
A user broke down my Video Assembly Instructions into this:
forum.dl2man.de/viewtopic.php?t=204
use it in conjunction with the iBOM´s on my page:
dl2man.de/2-trusdx-assembly/
Manuel, really fantastic video. Looking forward to build it. 73 de Neven 9A5YY
Where can I get the kit ??
right now there are open group buys available on groups.io/g/ucx/topics
Так и не понял, как изготовить трансформатор Т2
dimana saya bisa membeli nya
Ich versuche, auf alle Kommentare zu antworten, aber ich spreche Deine Sprache nicht. Um ein möglichst großes Publikum zu erreichen, mache ich alle Videos und Kommentare nicht in meiner Muttersprache Deutsch, sondern in Englisch. Ich bitte Dich, Deine Frage ebenfalls in Englisch zu stellen, damit ich sie Dir beantworten kann. Vielen Dank !
The 3D printed casing just looks a bit flimsy, maybe a machined aluminium case would be better, give it the protection it deserves.
The license of the housing is CC-BY SA (changes allowed, give credits and share under the same license) and the Step Files of (tr)uSDX are published on my page from the beginning of this project. So if you or anyone else likes: You can design ,produce and sell a metal housing. I felt finished, when the 3D printed housing perfectly represented the "maker flair".... 73 Manuel; DL2MAN
Super Manuel, dank dir für das Video. Habe sehr großes Interesse. Würdest du mir ein zusammengebautes Gerät verkaufen? 73 DL1EAR Andreas
Das wäre unbezahlbar.... Warte noch ein bisschen, es sind schon Chinesen dran, die ein "offizielles" Gerät anbieten wollen, welches dann von Guido und mir geprüft und freigegeben wird.
T1 and T2 inductors - in the video it is not clear how to solder it. You point the holes but not clearly. Please point out which winding goes where. 73

Hi Manuel,
I'm in Germany - Can you point me to a kit supplier?
Thanks,

Hello Mike, right now there are open group buys available on groups.io/g/ucx/topics
your hands are shaking
Correct. And how does this information help us ?
