TSW (the Triumvirate Skonk Worx of W0EB, W2CTX and N5IB) are pleased to announce the immediate availability of an inexpensive plug-in adapter that will allow a PJRC.com Teensy 4.0 with a 600 MHz processor and lots of flash program memory to directly replace the NANO in a V6 uBITX Raduino!

We also have available (open source) software for same Teensy 4.0 that runs and looks almost exactly like the original factory V6 software except it's many times faster and with lots of program space, has a few extra niceties built in.?

The adapter kit is available now, and details on how to purchase one can be found on the TSW website - .? The software is also available in the "uBITX files directory via the link near the top of the page on the TSW website.

I have one running extremely well on an actual Version 6 uBITX (basic kit) that I received a day before Christmas.?

I built it up using a 3D printed front panel & base I designed using the factory supplied acrylic front panel template for dimensions.

One nice thing about using the Teensy 4 instead of the NANO aside from the display speed is that it eliminates many of the birdies associated with the various oscillators on the NANO board and I can detect NO tuning clicks when the encoder is turned.?

The only drawback is with the 3.3V max input levels for the Teensy 4.0, the Factory's keyer code had to be abandoned, R2 had to be removed and the trace that goes from input pin A6 to the NANO and the "KEYER" pin on the 18 pin right angle connector must be cut to use the adapter with a V6 Raduino.? If this isn't done, +5V gets applied to the A6 input pin on the Teensy and will destroy the ADC in the Teensy.? We tried applying 3.3V to the Vcc side of R2 but the voltage divider outputs weren't read reliably by the Teensy's ADC and the keyer didn't work well at all.? We re-wrote the keyer to use the A6 and A7(spare) inputs with A6 being the DOT input and A7 being the DASH input.? This also requires a separate jack for the paddles but makes the keyer really sing if the mods are done.

TSW also plans our own Raduino Clone for the V6 that will have pluggable jumpers to cover removing the voltages and will operate exactly as a Factory Raduino using a NANO or by setting the jumpers work with the Teensy 4/adapter in place of the nano without cutting any traces or removing R2.? This will be available as soon as the PC boards get here and are tested, possibly next week sometime.? It's dimensions will be such that with the 2.8" ILI9341 TFT display mounted, it will directly replace a Factory Raduino.? It will be offered only as a kit but the kit price will be reasonable.? With the kit, the display and Teensy will not be supplied as they are readily available via PJRC and other suppliers.

Good grief!? Okay maybe this cartoon wasn't imported everywhere (Charlie Brown).?

v5 is a very nice rig - its a v4 without the bugs I am dealing with.? enjoy the v5.? honestly I appreciate the work that went into my v4.? and the upgrades are part of the journey.?

building a board and shipping it worldwide is a big effort.? do the math it can't be a huge money maker.? appreciate we are invited into the build opportunity.?

I won't write off any real quality control matters - do politely work those.? HFSignals does not have a huge complex, nor any storefront at all.? if you prefer that kind of business - they are out there.?

meanwhile with every QSO I make, this ubitx rocks!? and I enjoy improving it - and having it 'my way' (which is functional and rather basic) - while others are having a blast making theirs exotic.? and we can trust some hams around the world are getting a rig when other options are beyond their means - particularly many youth is the world.?

enjoy your radiations!?

Good catch on the "F", K7OME. Looks like it should be an 0xE2 instead. Best thing to do there would be to do one (or more) of the following:
a) make the fix, and create a pull request for it (best)
b) create an "issue" on github documenting the problem (decent)
c) mention it in a thread here (as you did, which is okay, but not ideal :P)

FWIW I did make the correction to 17 meters and now it works fine.? While I was in there I took out all the CAT related code as I don't plan to use this radio with a computer and I figured that would save a little space for future enhancements.

This should probably be in a different thread but:? is there any info on the status of the Morse reader code?? Finishing that is more than I can handle but I did see that the 'F' was mis-coded as an 'L' ....

I have read on Groups.io that the Nextion editor does have an invert setting that will allow for mounting the display with the microSD card on the top.? It would require downloading, installing and then recompiling? and downloading the Nextion display pages, though it is doable.

FWIW

RE: ease of screen reprogramming, might one be able to invert the display in Nextiin Editor, mount the screen upside down, and then have access to the card slot? It's worth a try.

Sounds excellent. I may do what you did. I’m looking at ways to save on current and I really like the CDC code. If you remove the 5v from the display I assume the radio will still operate? With your hookup it would be easy to add a switch.

I use the CEC Memory Manager to set it on my rig.? I believe that the CEC software maintained the v4 type Calibration menu.? When you press the encoder a yellow rectangle with the stock menu items comes up and you roll through with the encoder to the Settings menu, press and then go back and select BFO.

Memory Manager can read the current configuration and save it so? you can try out a new setting, and always go right back to a prior one that worked. I used it for both of my Nextion display uBitx (v4 and v5).

All of the links for the CEC software should be on this page:

including Memory Manager.

Post back if you have any issues.

FWIW and YMMV

Dave,
Do not hold your Breath as you may turn a bit Blue.
The "Early Adopters"? like usual got the shaft by Hf Signals, my $209 DHL Express? package had no Bubble wrap on any item if it was not for the DHL sturdy plastic bag the cheap cardboard box that contained the "kit" would have been all over the shipping world, I looked at my original 40 meter BTX and the box was 100% sturdier and that went via India Post. And we only have V5 with a low slow color display that may not be salvageable
The Shock to me was? to? after find out after payment that the Firmware right out of the box has a bug dealing with 17 meters that requires a new load that I was not set up to perform .Disappointed at the Shoddy Packaging and Shipping protection..
I guess it was my mistake and assumption that a V6 radio would have all of the corrections of all of the previous versions but in reality is just a attempt by HF Signals to capture revenue before before the new year and getting a V5 board? cleared out and calling it a V6.
I guess with the add-ons of the ALC and other ones to come after full discovering? the China clones of the little? DSP? color screen "KX3" like? radio? are looking much better in the long run.
Best Regards.

Hi David,

I was describing the features of the Groups.io web interface.? I don't view groups using email because it doesn't make sense to me.? One misses all the other features of a group such as this hashtags feature, as well is the group wiki, files, and photo sections.

Yep Dennis, but I think many have yet to discover the advantages of the feature, also, since I don't access the groups via emails, I'm not sure how the feature works there.? Maybe one can type in the hashtags manualy but I'm not sure?

Mark.

I sounds?SO simple BUT, getting user to do this consistently is like Herding Cats!

funny.? thunderbird does not seem to have this feature.

Hi Bill,

Before the mod I checked each display’s datasheet to compare power consumption and ?both draws around 60 to 65 ma of current.

I didn’t actually measure the current draw on the raduino board 7805 regulator but it does feel hot with both displays, stock and nextion. May be it is a good idea to swap the heatsink with a notch bigger one.

I used the rig continously for almost 3 hours yesterday for qso’s and nothing smoked up so I think it’s surviving the heat ?:)

Hi John -?

Thanks for the reply.? I haven't seen that setting - is it in the CW menu or the Calibration menu?? I'll look for it tonight when I get back to the shack.

Hi everyone,

Maybe these are a bit new to some groups.io users, but hashtags are a very handy way to keep the list organized, to receive just the posts you want, and to search for relevant posts.? They are also very easy to use!

When you create a new post, there will be a box for a subject line at the top, and right below it, will be a drop-down box that lets you choose the appropriate hashtag(s) for your subject.? For example, if you had a question about calibrating your ubix v5 radio, you can choose the hashtags, "ubitx", "v5", and "calibration".? If you don't see a hashtag that you think is needed, and will be a good category for others to use, you can first go the the Hashtag link on the left of the page and down at the bottom of that page will be a box you can click to create a new hashtag.

As a list user, you can go again to the Hashtag page and mute any topics that don't interest you.? For example, if you are not interested in the ubitx40, you can just mute all topics related to that.

For searching, you also can use the Hashtag page.? Just click on one of the hashtags, and all posts that have the hash tag you chose will be listed for you!

Cheers to everyone and HNY,


Mark.

Interesting, but we still have lots of commonality.? Problems - well many of these are common between v3 and v4 - that owners may wish to still use and advance.? display and other upgrades may apply to all or several versions.? v6 is merely the new generation.? we also have different audiences for those enjoying a basic ubitx rig and one that is highly tricked out.? I think its best we stay together.? Be patient to be in community with all ubitx owners.?

enjoy your build and radiations.?

not entirely sure 'what' custom filter opportunity you are referencing - but 'board headers' seems to be a clue.?

I remember there are pad features to interface with a second crystal filter - this topic has certainly been on the lit.? if you seek CW - a good CW filter is best at a much lower IF than 12 MHz.? its easy to make from lower frequency xtals - designs abound.? the 'bad news' - need to to add some firmware instruction to retune the BFO when doing CW.? it needs to be proven (if it hasn't been) - but it is possible that the SSB 12 MHz and a say 4.9 or 5 MHz CW filter could co-exist in parallel without switching.?

other v4 filters of interest - well something to reduce mixer spurious at 45 MHz.? v5 adds an LC filter.? I tried it on v4, in itself it does not have enough Q - so I suspect its part of a set of solutions.? adding a second 45 MHz xtal stage is popular - as reported here I tried it, it greatly reduced my CW transmit output.? I have since added SMT inductors with some shielding on the primary 45 MHz filter, so possibly it will work better - when I try it again.?

for CW and narrower bandwidth SSB - I am using a NESCAF audio filter that I am happy with.?

Curt

Hi,

Yes for sure Bill.? Everyone should add a hashtag to their post based on the subject.? Most needed ones already exist. Just choose the appropriate one and it will be added automaticaly to your subject line.

Notice, if you click on "Hashtag" on the left, you can mute whatever topic you don't want to receive.? Easy!

Very nice! I wonder what the current draw looks like with the new display? I wonder if it’s more or less than the stock TFT??
