Re: Uploading firmware to ubitx

Another great tutorial video.

One missing piece: on my version of the IDE, you need to select the "ATmega328p (old bootloader)" version. I know that's caught a couple people.

Great video! Clear visuals and explanations.

One detail that probably would be good to add is about the side band inversion if the BFO is tuned "backwards".

Hi Ralph,

I bought a special one so I can use an android phone to do a reset of the nano using the phone if needed. It was an 18 inch USB mini to USB micro connector adapter cable; the mini connects to the phone and the micro to the rig. It was about $15 and they said if I wanted a 3 ft or 6ft one the costs jumps up to $50-$60 range. Not a common one for sure.

Re: RX #V6 quits working when ant coax braid is connected #v6

Andy_501 <andrew.webb.501.ve4per@...>
 

Not recently, but yes I did in late summer 2018. I am inclined to believe it was kind of a multiple associated hit of side forks from a main fork that struck all rooftop antennas (SAT TV, Inet Radio Link, OTA rooftop TV antenna and possibly a ham antenna) simultaneously. I don't think it was a full hit of a main lightning bolt because likely that would have set fire to my residence as well.

  It took out ISP's POE internet antenna interface unit, two HDMI input ports one each in two smart TV's, two wired ethernet NIC cards in two separate PC's , and two video adapter display output ports on another two PC's (network file share server and NLE editing workstation).

My main ham PC USB onboard interfaces/hub disabling the PC entirely (had to replace it) the main LR TV satellite TV receiver, a yamaha two channel USB audio mixer, a Yaesu CAT cable and a SignalinkUSB sound device and I suspect RF input to my FT857.  It took almost 6-8 months to find each of the failed components and replace them one at a time and get back to now where it is almost all, except for the possible protector block in the coax switch, to serviceable. Ham PC new one is a refurbished one about $275 Cdn, FT857 repairs $300 + shipping both ways, Yamaha mixer and Sat TV receiver were under warranty, SignalinkUSB was $175 + $75 for replacement PCB for damaged one (so I could repair it myself but didn't find out I could until after a replacement unit was paid for and shipped to me) .

I was sitting in an armchair at 3:00 AM reading when the bolt struck, and I could tell by the sound of it that likely something might be affected, but had no idea how extensive the final end effects were going to be.

Home network ethernet cables close by runs of audio and USB cables and because it was all close to the ham PC onboard USB hub and network cabling the one hit was able to be induced into so many places because of so many interconnections.

It was not apparent immediately that there was widespread damage to so many components but it did demonstrate how it's effects can be transmitted/induced in so many directions at once and being like a major static discharge any module with any CMOS components at all can be damaged and not show up for a long time.

I had worked in electronics and communications facilities for 35 yrs and never seen such widespread damage as this anywhere. Usually it was just replacing carbon protector blocks or heat coils in landline termination points and reboot a system to be back in business; no such luck in this case.

When I had the SAT TV dish and receiver installed the Bell service tech did not install a ground; I had to fight with Bell engineering management to get them to install one and even then they only put in a 40' run of #16 guage insulated hookup wire as a ground when it should have been in my opinion #6 bare copper stranded ground cable. But then who am I right?

Lightning is very weird, expensive and not a ham's friend at all.

Re: new V6 owner with a few basic questions on wiring and software #v6

Hi Tim,

1. There are diodes, but no fuses.

2. A scrap speaker should be fine

3. Nextion versions won't work with the v6 stock screen. You'll either want to grab Ashhar's latest or my latest code from github. Ashhar made a video about it today: https://groups.io/g/BITX20/message/76435

Re: Size and type of USB program cable

Go to your favorite internet search engine, type in "USB connector types", then select "Images" from below the search bar and look for the one that matches you connector. I don't have a V6 (yet), but you should see one that matches. (I think it is Type B).

Re: Small change, huge thanks to Ashhar

I agree that it's a good way to be, but it's been "fixed" for a while now. According to the git history, the ino/cpp change was done back in Dec 17, 2019.

He also mentioned the change to you specifically back in January: https://groups.io/g/BITX20/message/75176

Re: Small change, huge thanks to Ashhar

Jack, W8TEE
 

All:

If you are an early adopter of the V6 µBITX code, you may want to get the new download, too. Ashhar went through the trouble to upgrade the new version of the software to convert all of the old *.ino files to *.cpp files. This may not seem like a big deal, but it is! There are several benefits to the change.

First, while there has always been multiple source code files in his project, now only one file ends in *.ino. This means two things: 1) the project's ino file is the "primary file" in that it contains both setup() and loop(), the program's main entry point, and 2) the project's directory MUST be the same as the primary file name. That is, if the ino file is ubitx_v6.3_code.ino, the directory for the project must be ubitx_v6.3_code.

Second, the huge win is for those who like playing around with the code, since this new file-naming convention allows the IDE compiler to perform incremental compiles. For example, when I was compiling the 19-file, 11,000+ lines of code in the JackAl project, the first compile in the morning would take a little over a minute on a pretty fast computer (i.e., 3.8Mhz, 8-core with 32Gb of memory). The first compile clears the "dirty flag" in the IDE for each of the source files. Next I would start editing the nettlesome file that is giving me problems and re-compile the project. However, since I only worked on one source code file, only that file has its dirty flag set, so it is the only file that gets recompiled. The linker then merges this newly compiled file with the previously-compiled intermediate files to form the executable for upload to the Nano (or whatever chip). For me, this drops the recompile time from over a minute to less than 10 seconds. If I can save 50 seconds on each compile and a typical day produces 40 recompiles, that saves me over 30 minutes of thumb-twiddling each day! Do that for 19 months, and it's almost enough time for a two-week vacation!

This seemingly-small change by Ashhar simply adds yet another element to the µBITX for which we need to thank him.

Dean,

Forgot about the direct frequency input on the CEC/Nextion.  Much easier than all that dial turning.  Only issue is it is not available for the stock 2 line display version of the software.

Thank-you for pointing the shortcut out!

Hi Maurice,

I can't help you without more information.  What specifically is not working?

The video shows that it can work and does for me, V5, CEC 1.2 firmware and Nextion display.  I believe there may be a setting in uBitx memory manager to allow tuning outside the ham bands, but I don't have time to research it this morning.

new V6 owner with a few basic questions on wiring and software #v6

tim.schubeck@...
 

Hi, new owner and just received my uBitx V6 unit yesterday.

I have a few questions as most of the information is for the older versions.

1. power supply: Do I need to add a diode to the board for reverse polarity protection or is there already one on the board since the power receptacle is already surface mounted? (assume I do need to add an inline fuse, i'm using a 3amp 12v wall wart from a hard drive enclosure but have other supply options--but the wall wart already has the correct wired plug end so it's quicker).

2. speaker: I assumed the included baofeng mic would double as the speaker (like it does on the UV5R HT's) but it appears to have the 2nd jack removed and rewired for mic only. I have an 8 ohm 2 or 3 inch speaker from a radio or something I salvaged I plan to use, is that too much speaker? or would I be better off using one half of a pair of amplified computer speakers/

3. Software: I see a lot of reference to replacement firmware. not sure which one to use; it appears CEC_V1.200 is the latest? if so, not sure which version in the zip file I should use for the stock V6 display--is it the Nextion version or one of the others?

I have several Arduino Nano's, I will likely just program one with the new firmware and pull the original for safe keeping. i've only uploaded code from the Arduino compiler, but the other is HEX, I assume there is there a guide to uploading the HEX?

Thanks for any input, i'm looking forward to playing around with this over the next few days.

oh one last thing, is it normal the volume control doesn't stick out far enough to use the nut on the threads? since it is mounted on the board with the end of the threads flush with the display (ie. it is set back from the edge a good 1/8") there is no way to fit the nut on the face plate...

Thanks again,
Tim WB8IZB

Many people have asked for a video to show how to download, install the ubitx source code and upload it. It is quite easy and I have a video showing you how to do it.
Let me know if I have skipped anything.

I have made a video that shows how BFO and Frequency calibration works. You have to do both together. Watch the video. Let me know if there are any gotachs (I got the frequency of AIR wrong)
