V6 display on v5

mm0bef@...
 

I ordered the v6 display for my v5 today. Once some people have had a chance to test their v6 could i have opinions on differences and ease of operation over nextion screens. Like the cec firmware but want to give the stock v6 firmware a go. Will also be looking into how much more complicated the firmware for the v6 screen is to modify.

Re: Raduino - what do I need to update (and learn to update) it?

Jerry Gaffke
 

John,

I suggest you get these Nano clones off of Amazon:
   https://www.amazon.com/dp/B0713XK923
Should be pretty much identical to the Nano that ships with the Raduino.
The header pins are not yet soldered into the board, this is important because
they will have to be soldered into the top side of the Nano so they can plug into the Raduino.
Normal people solder those pins into the bottom side.

Having these means that if you somehow blow the Nano on your Raduino,
you can replace it in a matter of minutes.   
Also, you can leave the working firmware in one Nano while experimenting,
easy to recover by just plugging the original Nano back into the socket
on the Raduino.  

There are lots of tutorials on the web for doing silly things like blinking an LED.
Play with some of those, see how the code works.

Anyways, you will also need a computer to
host the Arduino IDE, plus a mini USB cable to go from that computer 
into the Nano when programming it.  Make sure the USB cable works
to download pictures from a camera or something similar, many of those cables
are only meant for charging and cannot transfer data.

Next step is to figure out how to load the Arduino IDE on your computer.
    https://www.arduino.cc/en/Guide/HomePage
Another resource is 
    https://groups.io/g/BITX20/wiki/Raduino-Topics

And finally, get your computer to talk to the Nano over that USB cable.
This is where some people get hung up and start asking questions on the forum.
On some computers you will need to install a special driver to talk to the USB chip
on the Nano.  As I recall, Ubuntu Linux had no trouble at all, it just worked. 
 
 Good Luck!

They are both ARM processors.
But the Blue Pill processor is made by ST,  the Teensy by NXP.
Slightly different worlds.

Re: Cec v1.2 software question

Erwin Serlé
 

I just found and applied this http://www.hamskey.com/2018/04/improve-ubitx-receive-performance-by.html
and for me checking in uBITx MM software the IF function and then setting ATT=70 made a big difference in receive performance.

The number of FT8 signals received just exploded, at least doubled or tripled.

At the moment I am receiving WSPR and the system with the uBITx is better then my YAESU FT450D.

Of course they are on different antenna's

All this was after noting that my base frequency was allright, about 8 Hz different from FT450D (2ppm) on 80 meter.
And correcting the 'location' of my USB sideband, as this was too far away from the dial frequency.
I calibrated the BFO by carefully changing the big number in MM for USB calibration. In my case factory setting 11054600 and now 11056500. This took me 7 iterations watching the change in the 2 FT8 results: dial frequency and active bandwidth.

This started at 7.072.000 between 2300 and 4500 and ended where it should be at 7.074.000 between 300-2600.
Both VFO and BFO can still be improved I know.

Oh, I am currently using the latest CEC firmware 1.20

Nextion question from new member

Richard Lawn <rjlawn@...>
 

I just recently bought a ubitx kit from GigaParts and have not yet assembled it. I want to buy a case but before I do I wanted to learn more about the advantages of adding a Nextion screen as I want to be sure to purchase the right case. I like the electronic part of kit building but don’t care for building cases from scratch as I’m not well equipped for metal work. 

i wish I had known they were about ready to release v6. 

what other add ons are suggested as “must buys?”

Jack, you are correct.  Thanks for the correction. Roger Clark is the developer of the "original" STM32 toolchain ported to the Arduino platform. The platform most Arduino Blue Pill projects are still done with.

Maybe the work the people have done with the Teensy make it one of the best places to start, if you want to use STM32 and other more powerful boards with Arduino. As they are smart to focus on a set of boards that they build and have control over, and therefore can support with stable working toolchains and libraries.

Looks like the way they have kept their boards form being crushed by cheap clones, and afford to stay in business, is they have a special bootloader chip they keep proprietary.

I may buy some Teensy boards, do development on them, then when I want a new hair raising adventure I can try porting to a Blue Pill if cost is an issue.

Mostly I do my STM32 development with the STM32Cube tools from STM now. Great for the consulting I do, but still want to do some projects on the Arduino platform so they can be shared in the Maker/hobbyist, open source community. Mbed is another interesting developer platform that is meant for both professional and Maker/hobbyist projects.

Re: How to get rid of Local FM broadcast stations #ubitx

Anthony Gomes
 

Gavin,

As you said both the the station are 5 1/2 miles and they have AM counterparts. I am not sure if they are running the same shows on AM also because I feel you are picking up the AM signals. 
 
Since you are getting it everywhere and as Farhan said it could be getting picked up by audio circuit. I would have taken out the LM386 chip from the socket and check the pins make them straight and push it back gently into the socket. I hope that helps.

Gavin

hang in there a bit and solve this one, its quite unusual.  I assume that your antenna has to be connected to hear these stations?

if you happen to have any other power supply (even a gel cell battery), try to see if you still get interference. 

I don't recall you answered how close these stations are? 

As Farhan mentioned, check those connections to your volume control.  I think you mentioned these stations appear wherever the ubitx is tuned? 

I am also assuming you have successfully used that antenna (I have an EFHW here also) with another rig?  I can presume any antenna fault that would cause this issue, but asking anyway. 

In your photos - I see 2 very unusual coils of wire that maybe you made to try to neaten the arrangement.  I suggest straight runs of wire at the edge of the case - possibly you made yourself a transformer feeding this interference.  try touching each of these coils to see if it goes away.  sometimes careful use of your finger can help with troubleshooting - just don't do this in high voltage tube or AC power supply circuits.

Hi!

Are you sure you want to sell it instead of calibrating the BFO? :-)

BFO calibration takes about 5 minutes with a USB sound card on your PC.

Hi all,

I've bought a V5 board some months ago, I assembled it in a custom case with a good battery pack, connectors, etc etc.

I've well set up the frequency calibration (see there : https://www.tobeca.fr/f4ija/doku.php?id=ubitx:calibration)

But now I need to calibrate finely the BFO and I really have no time (we bought a house and I've a company to run...)
Instead of leaving this board unused I'd like to sell it to someone who wants a fresh start with an already assembled board.

The setup is working as I was able to make some contacts with WSPR and also FT8 but I really have no time to go further for now.

I propose the complete system with :

V5 board with stock LCD screen
the battery pack
the whole box (3d printed and CNC milled for the plates)
the connectors, etc etc.
the battery pack charger

You can see the project and the build here : https://groups.io/g/BITX20/topic/project_ubitx_go_box_with/33030891?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,33030891

https://www.tobeca.fr/f4ija/doku.php?id=start

I propose 200€ for this + shipping depending on where you are.
The price can be negociable, just please be honest and respectful.

Looking forward for your contacts !

V5 reprogram.

ronldt@...
 

I accidentally messed up some settings on my ubitx  when first setting it up. I want to reprogram to the factory defaults.
Where to I find the V5 software, and how do I transfer it from my laptop to the Arduino?

Retraction: Unfortunately, the nanoVNAs are not accurate frequency generators, sometimes as much as 10 kHz off.

I just checked my nanoVNA at HF. It was right on target. I must be remembering its performance at SHF.

I have yet to find a concise YouTube video or guide on how one actually knows when the BFO and calibration are both set correctly.

my guess is for BFO I’m looking for the setting where the “tone” generated by VNA goes away— meaning the frequency on the dial is now sitting right on top of what would be the carrier.  But I could be completely wrong.


but seriously, the descriptions of “zero beat” I read online don’t click with me...   this stuff is all just math... surely somebody can describe it that way.

Is your antenna resonant at the frequency you are listening to, or is it a random length of wire?

When first testing my uBITX v5 with a random antenna, I had all kinds of interference from local broadcast stations. Figured I would need to use a high-pass filter on the receiver. Then I changed to using my 40/80 m dipoles (parallel) and all the broadcast interference (BCI) disappeared. Ha! No HPF needed after all.

By the way, we are talking about AM broadcast interference, aren't we? Not "FM" as the subject line says?
