Thank you!
I'd love to buy one of these!
Very cool. I'm a bit disappointed that I have the speaker buzz - and I just bought mine and it's r1.0 Still great device though!
Does anyone know if the flat top or button batteries are required? Some devices will allow either one, but not both. It looks like he is using flat top, but I see a good deal on button top batteries with charger, so I would like to know if they will work.
Ich schreib dir einfach mal auf Deutsch 😀Bin von Joe Vogel hier rüber geschwappt. Kann dir sehr die Videos von Gear skeptic zu dem Video ans Herz legen. Bin vor circa zwei Jahren auf sein Kanal gestoßen, als ich mich mit dem Thema Wasseraufbereitung auseinander gesetzt habe. Ganz viele Grüße aus dem ebenfalls Bayern! 😀 und by the way, sehr sehr gutes Video! Die restlichen Videos auf deinem Kanal werden ebenfalls noch angeschaut. Abbo haste schon mal 🙂
Great video! Can you say a bit more about the paddle used?
If i may ask. Where did the orange mic come from?

Love your videos! I have one of your radios. I haven't worked with it much. I will in the near future. Thanks!
Great information thank you
Just ordered mine from aliexpress item/1005003908457475.html .... they're saying they know you in the description! Fingers crossed.
Thanks a lot for the video. I’m using Katadin befree for filtering dirty water after using Grayl. Using them 2 years and after your video more satisfied with them! Subscribed!
I sometimes go portable and use UNUNs with FT240-43 toroids to handle 100W SSB or 30W FT8. Do you think the FT114-43 toroids will be able to handle this power level ?
The 114 probably not (for long) but 140s should be good to go.
Excellent investigation. Thank you for saving me a lot of time !!! It would be interesting to try and compare one more core: the Fair-Rite 2643251002 which seems to be gaining popularity. Perhaps you have already done this. I am subscribing !
Thanks Manuel. Can you tell me the total length of the wires for uhf and vhf. Thank you
I finally completed the 2m Moxon build today. SWR is 1.1 on 144.200 and 1.24 on 146.52. I'm very happy with it. So easy to put together. Danke schön, Manuel! If anyone has modified the center adaptor part I'd love to print various versions. Currently in need of one with a 10mm hole for a carbon fiber mast.
Hello.. Does it sort the audio out with this fw all ?? Hope so 🤞 Thankyou kindly 73z.
Thank you, Manuel! I've been using the (tr)uSDX for a year, and it's such a great little piece of tech art, considering its hardware limitations. Unfortunately at some point the SMA connector broke away from the PCB, along with some traces, so I had to replace it by BNC flange connector, externally mounted to the body, it works fine. 73 R1BNG
Hello Manuel, you were quicker than I could reply, I have now found the part. 73 DL9GAW
Hello Manuel. Unfortunately I have not found the correct version of the BNC socket for this Moxon antenna. Can you or another OM let me know here? Best 73 Gerd
If you follow the link to the print files, there´s links in the description to the parts, I´ve used.
I got one of those and it did not work untill i cracked it open and . fixed the mike circuit it had unusable audio .... i wish i would have found you sooner if i get another one of these i will get ahold of you first ! thanks for your work and keep up the good work
Thanks for your kind words. Unfortunately we could not prevent everyone from getting ripped.... Hope to meet you on the bands. 73 Manuel; DL2MAN
Printing several parts today. Very nice!
Thanks !
So I sold my 705. 😂 But I have a frequency counter. Am I looking for 14060KHz or 14660 KHz on the counter?
SImple answer: Yes !
I powered up my FT-817 and used the tuning tone, zero beat with that. RBN says I’m on frequency, that’s good enough for me! Thanks!
Thank you for these detailed explanations! 🙂 I recently heard someone suggesting that people who are new to ham radio (like I am) might want to buy their first transformers rather than building them on their own to avoid a potential point of failure. However especially with what you explained regarding how to check if it actually works I am encouraged to build one myself. 🙂Thanks again. Subcribed. 73 de DO1HNR, Henner
Thank you so much for the kind words ! This is the whole idea behind this channel: Take away the fear for the tech stuff ! It´s not rocket science, just radio stuff. Everyone can do it ! 73 and I hope to meet you on the bands real soon ! 73/72 Manuel; DL2MAN
Is this mod possible on the qcx mini 🎉?? Thankyou because I’m thinking of getting one ✅
With QCX Mini, uSDX was recognized by G0UPL. It has the mod made easier on board already: dl2man.de/qcx-mini-usdx-mod/ 73 Manuel; DL2MAN
In englischer Sprache tu ich mir nicht an!
Alles kann, nix muss ! Danke für den Kommentar. Das hilft mir für den TH-cam Algorithmus.
Hi Manuel, what budget RFpower amplifier do you recommend to use with the (tr)uSDX? I've heard you can get one with filters to avoid making a mess on the band but I don't know anything else about it, I think it provides an output of about 40W. Thanks. 73's. LW3EOV. M6BGG
Sorry, I have no recommandation for you. I don´t use a PA with (tr)uSDX anymore. I´have used a commercial PA in the past.
@@dl2man Ok, thanks, regards.
I used this exact method to zero my frequency, I even have the same dummy load. However I noticed the tr usdx constantly transmits even when the PTT button is not being pressed. It’s a very low output, but still visible on my 7300 waterfall. Is this normal?
This is normal with a direct conversion receiver.
As this video is 2 years old, is the information about the alternative band modules around 26:00 minutes still accurate? What band module is shipped by default in mid August 2024?
Still accurate. Low bands is the only option available assembled. Classic and High bands only as Kits.
Manuel. Love this. I can’t make out the cable you said you used and you didn’t mention the push connector used. Could you let me know it Thanks.
Cable for Balun is RG316. Coax Cable to connect is RG58. BNC Socket is this type: www.amazon.de/rechtwinklig-L%C3%B6t-Leiterplattenmontage-Schottverbinder-Kunststoffart-BNC-%C3%9Cberwachungsvideostecker/dp/B07X3KG3XT/ 73 Manuel; DL2MAN
Hi Manuel. Great design mod. Do you have the weblink for Sonny website

Vers good 😊
Truly amazing, thanks for sharing with all of us, the 70cm Moxon doesn't fit in my printer, could it be made in two parts? Thanks and 73
Probably could be , but I won´t provide the files for it. 73 Manuel; DL2MAN
Great Video, comes at the right time - thank you very much! May I ask what type (brand) of filament you're using? Your prints seem to look absolutely awesome! Think, you mentioned in a previous video, that you are using a Prusa printer? Again, thank you.
On this print I´m using "Das Filament" PETG. However, while I still have my old trustworthy workhorse of a printer "Prusa i3 MK3S+" it´s currently unemployed.... I switched to Babu Lab X1C.... One hell of a printer, that makes anything else look vintage..... 73 Manuel; DL2MAN
Would be great to see those bands alive again in SSB/CW. Unfortunately it can be very frustrating outside contests. But your / Davids design is great and hopefully will motivate OMs to become more active.
Manuel… sounds fair to me! 73 de KD6UYK (Tim).
Amazing what would that cost to produce?
Does the unit charge the batteries ?
No. That's a passive cell holder
Hallo Manuel bei der Programmierung ist was schief gegangen es kommt immer eine Fehlermeldung und wen man den tr sudx am Strom anschließt erscheint die Registrierungsnummer sonst passiert nichts kann man das Gerät retten oder ist der nicht reparabel vielleicht erreicht dich diese Mitteilung 73 DG6MGR
Normalerweise schon. Nach Anleitung bootloader neu aufspielen, dann firmware neu auspielen. Für troubleshooting -> forum.dl2man.de
Super Video, vielen Dank für die 3d Dateien
Hi Manuel Very much enjoy your exploits. You mentioned firmware re the hand held. Are you going to explore that further. Very interested in that. Kind regards Richard. VK2VD
Hi Richard, I have 4 devices here which were all flashed by myself with the new firmware. So it was already explored a little, or do you mean making a Video ? th-cam.com/users/results?search_query=quansheng+IJV Didn´t plan on that, but if your thirst could not be quenched on TH-cam, maybe I need to do it, to show it in practice. 73 Manuel; DL2MAN
Que precio tiene pir si express..lu5pam..73
Ich verkaufe nichts. Bitte auf meiner Seite nachsehen, im Bereich "Where to buy"
Very nice design but the horizontal polarisation will be less than ideal on VHF.
Don't ask my why, this has historical reasons, I can't explain but: 2m/70cm SSB and CW are always horizontally polarized, while for FM vertical polarization is being used.
KK7SWB- Hi Manuel- when i calibrate manually by just doing it through the menu, i am still one to two kHz off as i can see from my other radios- is this normal?
TNX Manuel, it is pure ham spirit to share your work and all the files you developed for free and encourage other hams to build a DIY version of this antanna. Looking forward to your next videos 👍😃,‘73‘s
nice design! tnx Manuel. Will build one as soon as Im back home from vacation :-) 73 de Jan, DG1JAN
Great great job Manuel !!! Thanks so much for sharing your excellent work with us . I definitely have to try that out. The small plastic pipes you use what are they sold as in German Baumärkten. Installationsrohr ? Bewässerungsrohr ? I’m going down to Germany in a couple of weeks and try to find some of these. Absolutely professional job Manuel. 73 from Sweden
Hi, I think they can be found in department for electrical installation. Or multi purpose material department, where you also find various profiles, like L-Shaped Aluminium rods. I bought it from Amazon (see link in the description of the print files)
Hi could I please ask what is the total length and width of the 70cm antenna as when I tried to put it on my 3D printer the file shows as being too long to print, as the model was off the edge of the printer bed, I have a creality ender v3 which has a bed of 220x220.
Longest length here is 245mm...just fitted on my P1S.
I'm in the same boat with my Ender v3. Bed is too small to accommodate the 70cm design. I will have to have a friend print it.
Great stuff, thanks for the files. Printing as I type this! 👍
Fantastic stuff! Thanks for sharing.
what is your favorite coax for portable operation like this on 2M?
RG58. Not because it´s the best, but because I have plenty of it in various lengths and it´s dirt cheap. Probably not the reply you was hoping for. But If I´d buy something specifically for VHF/UHF, I´d probably buy something in the size of RG58 with less attenuation. AT least for this ultralight portable stuff I´d not go about RG58 diameter. Plenty of options these days.... 73 Manuel; DL2MAN
@@dl2man no trouble! i just wanted to know. i also use alot of RG58, but now i found out about RG174 and its pretty OK for most things. it get expensive though.
@@Francois_Dupont I avoid using RG174. Instead of that I use RG316
@@dl2man is there something i am missing? i looked online and they both seem pretty similar except that RG316 has a slightly bigger inner conductor.
Mechanical stability ! RG174 is easy to break, while RG316 is way more robust for use in the field.
