uBITX HF Tranceiver - Overview

[@N4GW]

I have a malamute SDR without a case. I saw this video and built a wood case. Thanks for the inspiration

[@jasonbrambach6957]

Thank you AB5N. I am an electronics hobbyist who recently became a ham. Coincidently, I have been taking a online Udemy course by Shawn Hymel about Arduino... so stumbling on to this video was wonderful. I had not even bought my first radio...until today! Now I can have the fun of combining all my hobbies into one fun project. I will get to start on the ground floor with QRP and can begin with CW (something I have been studying for almost a year). My call is ky9i...maybe you will hear me on HF in the not too distant future. Your videos are high quality. Thank you for your hard work and for sharing so much knowledge, Mr. Nagy.

[@robertnagy2163]

Jason- Welcome to the Ham fraternity! It's really fertile ground for networking and cross-pollination of ideas. There are SO many new facets of Ham radio right now to investigate. The uBITX will serve perfectly on the new FT-8 mode. You are global with 10 watts and a Dipole antenna. Check into the way that FT-8 is coded...very cool. Best of luck and glad you got something from my videos. 73's Bob

[@MatthewN8OHU]

For folks that are interested right now, I ordered one of the version units over the weekend and received it today via DHL to the US.

[@audiobrian1]

Great review Bob! I’m a not-quite-licensed newbie ham, but a lifelong EE analog/digital design engineer. I greatly appreciate your knowledgeable review of the cRF circuit design! I just subscribed to your KZbin channel, and look forward to hearing more of your videos! 73!

[@zzarkS]

Mine arrives Monday. Very excited! I believe the alternative firmware is from KD8CEC

[@chosesomething]

'Indian Standard Time' means the same thing everywhere wow! We thought it was infamous only here in India. Nice review btw. Hope I can get my hands on a uBITx someday. More than that, how does the electronics inside work, always fascinates me, a newbie electronics enthusiast

[@robertnagy2163]

Yash- I cannot give you a detailed description, but it is all on their website. It uses an Arduino...made into a Raduino.. a signal generating device. Indian standard time is only known to Americans who know Indian people! We have a lot of Indian Doctors, lawyers and others who live in HUGE houses and drive fancy cars. They are living the American dream. Happy people indeed.

[@chosesomething]

@@robertnagy2163 Yeah thanks I'll be going over their website for the technical. For those who don't know, Indian Standard Time (IST), is like that feeling when you're waiting for your order for like 45 minutes & you can't leave because it was prepaid, you're hungry, the order is 'just' coming and they are simply the best at whatever they make. It's a feeling that can only be experienced never described :P

[@robertnagy2163]

@@chosesomething Yet Excellent description!

[@KennethScharf]

I'm thinking that a surplus ammo box would make a nice box for the rig.

[@patriot9455]

I have an ammo box, sounds like this could be sweet "go box". I would look at a small AGM battery. There is a 4 inch tall 250CCA AGM battery that might be just the ticket, put charging post on the outside and a digital battery meter on it. Harbor freight here I come!!

[@boratsagdiyev3936]

Real good review, lots of info, and clearly very well thought out. Thumbs up.

[@JnJTrueOutdoorAdventures]

Great video and glad to see there are several options. I am planning on ordering one, just haven't bit the bullet yet. 73 Juddie WD8WV

[@whitefordpipeshandmadebymi7238]

Definitely gonna build one of these! Thanks ! Take care! 73 de ve3hip in welland Ontario Canada 🇨🇦

[@richardmolby9189]

Thank you for one of the best reviews of this rig. I am assembling mine now and hope to have it working soon 73 Rich K3OE

[@VE3FAL1Fred]

Robert what a great video, I have ordered one as well after looking at other radios out there. Very cool job Robert, I have joined your channel as well. Cheers Fred VE3FAL

[@igrewold]

Great review man, thanks a lot :) Good luck

[@malchaschwatrz5706]

Thank you . Great review and well done.

[@VE1XT]

Thanks for the video! It was a great review! - VE1XT

[@SevenFortyOne]

Thanks for the review...this is a very interesting piece.

[@igrewold]

Yeah, I wish I could get one but know nothing about Radio! :/ www.ti.com/lit/ds/symlink/ua741.pdf

i put a small shim so as to slip over the small shaft on a 1/4 knob 73 kg6mn

[@antennebuis]

Mine comes yesterday ,afher spent some hours for calibracion first BFO off course .But when i click on the ptt for ok the signal are always 2,5khz of the origenal .I dont see CW in the display also only USB and LSB .When i go in tx i see CW in the display but my tx signal comingout 2,5khz above so 7027 is 7029.5 in rx .Afther four hours there was smoke on the audio chip ordened 3 new pieces this morning on Ebay .I hope on a good end Thx for the video Bob 73, ON3MK Mor

[@jeromegrzelak8236]

Figured it out rotate knob to band of which you want then push countroller in

[@kn6bst349]

Great video. Thanks for the insights on the software. Many on YT suggest a fuse to the device. Where would you connect on on the µBITx? thx

[@robertnagy2163]

Just in line with the positive DC voltage lead - power cord. 3 amps would be good

[@kn6bst349]

[@tiboregedi99]

Szia! Honnan lehet megvásárolni ezt a rádiót?

[@VK2DMH]

Thank you, Robert, for a concise yet really useful review. Now I think I am now going to have to buy one of these HF rigs. It looks like my biggest challenge will be finding a suitable case. 73 de David vk2dmh

[@wadepatton2433]

Thanks Bob. I don't know my circuitry very well (yet) but I'm pretty good at making boxes. Your minimalism is great, but maybe the BLOB mic is pushing it (a little! 8-P ). FB 73 OM

[@2pi628]

Thank You Very much!!

[@KevinModerow]

Hello Bob, Great meeting you at Dayton. Did you do anything about the uBITX's power dropoff in the lower bands like 80m?

[@Yavor54]

Kevin- nope. He used really low-cost transistors in the final on the UBitx.. Upside is you can replace them for $3. Downside is power drop-off. It's a low-cost radio....and great meeting you too...looking forward to next year.

[@toddbu-WK7L]

With the cost of wood these days, that case would probably cost you more to build than the radio now :-(

[@k2icc]

I have seen the addition of a bigger touch screen display. Looking for instructions into build one now that a vendor in the states has them. Great stuff. 73. KD2QMZ

[@techguy9023]

There is a group online about the bitx 20 but covers this model too: groups.io, lots of good tech info there.

[@yeetboi962]

is it a bnc male or female connector.

[@haydenforarkansas6555]

Female

[@yeetboi962]

thanks

[@michelemazzilli8260]

Dove si può ordinare il m bitix

[@jeromegrzelak8236]

BOB i found my issue my program was ok but i was looking at someones advanced program other than mine

[@BarefootBeekeeper]

It seems to have doubled in price since then.

[@robertfleming5193]

NO so239 connector not pl259

[@Yavor54]

Correcto! Most people do not know that the female PL-259 is a So-239.

[@jeromegrzelak8236]

IM having trouble changing banda the easy way can you help oh i love my ft 991 tnx kg6mn

[@Yavor54]

You have to add a simple switch (push-button) across the main tuning dial switch wires. This way you can set the band- take your fingers off the tuning dial- and push the button.

[@ВладимирВеселов]

интересно сколько стоит аппарат

[@Yavor54]

Это стоит 380 долларов от китайцев. Сейчас есть новые модели, и они стоят дороже. Это все еще хорошее радио за 450 долларов. Я здесь первый год учитель русского языка!

[@martinryan5069]

Put the birdbox back 😁

[@gregmodder5439]

Yeah wow the KD8CEC firmware is far superior to what you have loaded... better look at that again.

[@Yavor54]

Yes, it IS amazing. One has to remember that the basic performance of this radio is....basic. No manner of display, software or additional arduinos is going to change it. It's a VERY rudimentary radio with marginal performance. Still, it is fun to put a top-shelf "face" on it.

[@jeromegrzelak8236]

sorry banda sb bands kg6mn

[@chrisn9140]

They have the option of DHL - Their cheaper shipping is through India Post. The same time frame is when you ship something from states to other parts of the world via USPS - commenting the shipping time and making fun of it as "Indian Standard Time" - is somewhat disappointing from a Senior like you.

[@Yavor54]

My Indian friends and I all laugh about "Indian Standard Time". Nothing derogatory.

[@duaneshuster6366]

My ears..... Ouch awful winey. SSB conversations more welcome. No explanation or naration ok.. but gives us the idea though. So crank up some good music and watch without tube volume people! So looks like a design your own S meter graph via the india-ware. cool inexpensive rigs I'm waiting for an all mode model no skipping AM FM extra $20 I pay tee hee. lol.
