I am thinking we are coming at the matter of 'unclear instruction' from many angles.? The instructions provided by HFSignals do address wiring up the uBITX.? Much of the confusion described by builders relates to installation into a particular kind of case.? While I confess to having had my own issues, the data is around to address each of them in assembly.? Since the product is 'intended' to be installed or applied in different ways, its not possible to provide clarity in them all.? Some folk may have been expecting behavior like a commercial rig or ease of assembly like XYZ kit - but neither is intended by the venture.?

There are some fine assembly videos now on line.? The community has contributed greatly on lots of fronts.? I am thrilled to be part of the community as we continue to advance this rig.?

Thanks for the file but it won’t download? When I click it it’s just numbers in the browser. Unless i’m missing something....

Hi, I have built the nano I2C Signal meter from hamskey but I can't find the HEX file to upload to the second nano anywhere?? Can someone point me in the right direction please?

Note to thank Gordon (KX4Z) for the collection of interesting and informative articles recently linked to in another post - APPRECIATED!

Perhaps not everyone will derive benefit or every article topic will be of interest but nevertheless thank you for sharing.

I will start by documenting Windows and Linux source code builds of

Folks seem to have issues with that stuff.

I am also fortunate to have a Spec An, so happy to re-run all tests
again to provide some newbies more information on what the difference
is between a spur and a harmonic etc.

Right now busy prepping for the amplifier project while I wait for the
Amps from Hans to arrive.
I need to now go look at what Steve shared

Wow Steve, that’s an extraordinarily impressive set of documents! I’m going to send some of that to our local club and show them what incredible stuff your club has been doing!!!

And you’ve got spectrum analyzer photos that suggest the daughter board relay solution worked quite well! Why did I even need to buy a spectrum analyzer?


Is it possible you could show us a photograph of the physical way that you built one of the daughterboard systems? I did mine pretty crappy, you might have had better lead dress or something that is important for people to know

Thank you so much for taking the time to write all that up!

My two cents worth:

There are many folks out there that just aren’t content with life so they try to make the rest of us (me too) look lazy. They are the ones who after a long day at work teach a class, write a book, Elmer, etc. I have just met another one recently who retired and is busier than ever with the above. We have two of them in our radio club who recently retired and moved to our town and now are talking on major projects in our club. Love those folks. This discussion just might stimulate one of those folks to write that book about the Bitx and uBitx. I would pay for one.

Another thought. Don’t buy a Bitx or uBitx kit unless you have a local guru to bail you out when there are issues (note: I did not say “problems”). I gave my Bitx40 away to another younger smarter (more educated in the field) ham who is building it step by step and the receiver is now working. My frustration level at my age is too high so I stick to small kits with Heathkit like instructions..... like the QCX. I still have the uBitx with a beautiful case that someday I may tackle but the QCX is more rewarding for me.

Nuff sed. SOMEONE please write the book. Again, a big thank you to those retired guys who are writing the books on Arduino.... I still am struggling with that but there is hope. I at least see the tunnel.... the light at the end will have to wait a while.

As far as I am concerned you as well as most people here are great and helpful.

Have a total of 280 dollars in our 3. Have worked all states with mine on phone. They are not toys but serious radios and work pretty well. I usually get reports about excellent audio quality.

I have told many that they should not have a ubitx, many need the radio that is all put together with all the settings finalized. and a thick manual. If it isn't right you send it back to the store.

The ubitx is not just one that you buy plug in and use. Although my first one was nearly that.

If you are really done with your junky ubitx send me a PM. Let me know your terms. If agreeable I'll take it off your hands.

Hi Dan,

I loaded UBITXV5_CEC_V1.122_16P.hex into my v5 and it works great.

Hope you have the same results.

But I am still trying to get my 3.2 NX display to work right - it leaves about 1/2 inch on the right side.

but for now I just use the 16 x 2

For our club build, I sent Gordon's gerber files to JLCPCB and got 20 boards back in about a week for less than $40. Parts came from Digi-key. We are installing the relay board on top of the LPF section of the uBITX board, supported by a metal stand-off at the corner, and a nylon stand-off at the opposite corner that just rests on the uBITX board. I had good results just using hookup wire, but ultimately went with coax for all RF inputs and outputs for extra harmonic suppression margin. This mod is working well to make the radio compliant relative to harmonics.

A second mod is required to reduce the spurs appearing below the transmit frequency, when using SSB on the higher bands. We are having good luck with an additional 45 MHz crystal filter mod right before the final mixer. Unfortunately any change in that portion of the uBITX circuit aggrivates a resonance near 7 MHz that reduces CW power on 40m to about 2 Watts. Just removing C22 causes the 40m CW power drop. I have not spent much time exploring this issue. Rewinding either T1 or T2 may resolve it.

this is what we are using --



it works nicely.? but no one that I know of is kitting it.? it's a small board that can be mounted in the corner above the main board. it is connected to the main board by 5 little pieces of coax and 5 wires.? essentially it replaces the input side of the relays.? You will recognize the designer from the list.?

perhaps someone will decide to do some business on this - would be nice if a kit would be available on each continent.?

full disclosure this is a major help, but not a complete cure.?
