Professional Programmers

James Lawrie
 

Ive been on this group for awhile now and noticed posts from others in past that they were professional programmers and such. 

If this is true and you are proficient at programming for PIC, ATMEL, MSP430 series and or DSP MPUs using C or Assembly I would like to discuss a plan with you for a project I need help with that will be of benefit to everyone on this site. I can pay for your services but in the end it will be Open Software. I’ll even provide the parts, please let me know.

People might like a better option than what is already here.

Thanks,

Plastic vs Metal Cabinets

Mike Lichtman
 

I know that Farhan has recommended a metal enclosure for the uBitx but I see many people using plastic. Has anyone
who has a plastic enclosure encountered any problems with it so far? By the way, I ordered on 12/17 and received
an email that it was shipped today. 73 Mike KF6KXG

Re: Plastic vs Metal Cabinets

Thomas Sharka
 

Yes, the plastic enclosures are more prone to external RF. I'm using the popular chinese cabinet and have a TS-100 soldering iron powered by a laptop brick that puts out a rather large RFI footprint. It floods the uBITX receive while under temperature regulation. If the uBITX were in a properly grounded metal case, the interference would be considerably less. I can get within 1 foot with the TS-100 and cause the receive on the uBITX to be swamped. I'm currently looking into improving the shielding on the TS-100 to cause less of an RFI footprint.

bitx 40 cat and digital modes

R. Kuehn
 

Hi,

I know there have been some threads on these topics before, however I'm kinda interested what the current 'state of the art' is, so to speak.

Is there anyone using CAT control on their bitx 40, and how are you doing it? If you are doing digital modes are you using VOX circuit for the PTT, or via another method. Thanks!

OOPS, Regarding Clock 2, it will show the display frequency only in CW mode and only with the key down.

Re: bitx 40 cat and digital modes

Joe Puma
 

I successfully used FT8 modes and jt9/65 before that. I used a raspberry pi with a usb audio and connected mic and speaker to that. For PTT I used a gpio pin on the rpi and made a ground ptt circuit. Wsjtx did the rest. 

There is CAT control for the bitx40 and wsjtx has good CAT control support.

Re: uBITX Firmware (CEC) 0.30 released (Test version). #ubitx

Jack.

I am always thanks for your advice. 
I decided to follow your advice and work for about an hour and change everything to cpp.
For the time being, i will keep the existing .ino (for forked other source) and provide the converted source to .cpp when version release.

Hi Ian:

I think you should consider it, as you have lost all type checking across files by making them all *.ino files. Obviously, this has not been a problem, but might be in the future. Just a suggestion to restore type checking.

Thank you for your attention and advice.
I first used Arduino. So I thought that Arduino was this style.(I did not know.)
I also decided that it would be nice to keep the original name in order to share code in github. In fact, some or all of my code has been merged into someone else's project.
On the other hand, I received a pullrequest request from someone else and my code was modified.
But now I was wondering if I should keep this style with little or no original source left.

I released it to version 0.35 a few hours ago.It's got more features than I thought with the help of many great people. they has good idea and good suggestion.
I have put all the functions I wanted to put in, except to build in wspr. So going to release Major in 1.0 soon.
I think this issue should be reconsidered at that point.

Thank you again for your interest.

Hi Ian:

No pressure from me, as it's your software. However, I think type checking is a real useful tool, especially when debugging code. I think everyone will appreciate it.

Thanks a lot once more Ian for your very prompt response and guidance on split function.

I will upload 0.35 this morning and give it a try.

Thanks for using this firmware.

split mode is very simple implement. when TX start (CW or PTT), Change VFO, and finish TX, back to VFO.
It actually took less than five minutes to implement. Because it is so simple structure, there is probably no big problem.
Instead, I put Vfo to Channel, Channel to Vfo in v0.35. It is a function to put frequently used frequency into a channel and to call it as a VFO.
With uBITX Manager, you can using adjust Hamband, TX control, builtin memory keyer(autokey), adjust tune step... and Accurate CW Keying by entering precise ADC value input

I hav plan to change the version to 1.0 this week and work on the video and manual.

Thanks agian.

Hello Ian,

Thank you very much for the updated version (CEC) 0.34 which is the first that I have uploaded to my newly received UBitx.
It has greatly improved the way my trx operates.
I will be testing it for a while, but generally speaking what I've tested up till now works to my expectations. Congratulations.

One thing that it is not very clear to me is how the split mode works. Is there a link or video for it? It would save me some time from trying to guess how and it would be greatly appreciated. As you may figure out, I also like to chase some DX as a QRP station!

I would like to invest some time to some necessary hardware improvements, number one being adding AGC (testing at first the original schematic), and then adding the s-meter to pin7.
I hope I can also find some time to play with your UBitx Manager.

Taking this opportunity, I would also like to comment that you are doing a very excellent job with your version of firmware for UBitx, and we as users must feel very lucky for that. Please keep the good work.
 
Very sincerely,

Re: Diy oscilloscope #parts

I purchased this one. My radio tech manual shows test points up to 8v so I think this probe should cover it. The other one said 3v input max.

It's more likely to work, and you are more likely to get support if it doesn't.

Re: ubitx AGC?

Konstantinos Konstas
 

Hi there Alex.

Thanks for the info.
I am thinking of doing the same as AGC is needed with some QRO signals in the bands.
Based on the attached schematic that I use for reference I have a couple of questions.
C78 on the top schematic needs to be removed or not?
R253 needs to be changed from 10K to 1K as in the bottom schematic or not?
Of course C78 has to be removed and R70 replaced with a 2K2 one. This is obvious.

Thanking you in advance,

73 de Konstantinos, SV1ONW

The more I read about these FETs the more they seem to behave like valves/'toobs'. A symmetrical output stage driven anti-phase each side is a form of Class B. If there's a non-linear section at turn-off/on then bias above that towards the linear Class-A. That means a small(ish) 'resting' current at Class AB. I'd go for the 10mA/side 'static' bias. 100mA is operating each side in Class A - very linear but very inefficient (more heat!), fine for the Bitx40 but not the uBitx. Has anyone investigated the 'valve-type' transfer curve(s)? How much bias to get beyond the non-linearity into linear (distortion-free) operation for spectral purity?

Good morning, Bert

The project does not require a shield.
The 2.8 display plugs directly into atmega2560.
Others sizes of display will plug in as well

Hi DR fellows
Just asking if anyone is thinking to change the rotary encoder of the uBITX to an optical encoder due
the not good quality of the uBITX encoder. 
can it is possible?
I found this on ebay: https://www.ebay.es/itm/Rotary-Encoder-400P-R-6mm-Incremental-Optical-Shaft-Working-Measurement-5-24V-SH/252550089532?hash=item3acd288b3c:g:uVsAAOSwmLlX4i36

W0EB/W2CTX Latest uBITX software release #ubitx

Jim Sheldon
 

This software is for the original uBITX Raduino with a standard (NOT the I2C) display.
The zip file contains a complete, illustrated manual in PDF format that contains
detailed instructions on implementing this version of the software.


We have totally restructured the menu to make it much easier to use.  The Nano's CPU cycle usage has been optimized for vastly better CW (a minor front panel wiring change is necessary to use this software).  Split is working (you do NOT have to be in transmit to change the transmitter's frequency) and though not available yet CAT is being worked on. Not promising CAT anytime soon but we're trying to implement it and keep CW working right.  (Not an easy task with a Nano but we want to keep from having to change out the Nano for some bigger card). Due to an easy programming trick, the keyer's dash paddle AND the Hand Key/external keyer connection has been moved to the same wire as the SSB PTT on the Raduino's digital connector (the orange wire).  This is possible since we don't normally use the CW key or paddles when in SSB mode and we don't use PTT when in CW mode.  The menu item CW:Key or CW:Pdl selects whether or not the line is used for the hand key or dash paddle.  This requires a minor wiring change and either a short adapter cable to be built for the hand key/external keyer or a separate hand key jack be added.  Either way it's an easy mod.  This change gives the analog A7 input back to the guys wanting it for an "S" meter or power/swr metering.  The blue wire (A6) remains as the dot input.  Since we don't have to select a specific threshold voltage on A6 for dot/dash/hand key and just determine key up or key down, the 2.2K and 10K resistors are no longer needed and the CW paddles work MUCH better. 

I posted the ubitx_V2_00R.zip file in the files section yesterday but there is so much stuff there that I'm posting the software again here to make it easier to locate for those who wish to use it.  Feedback is always appreciated and we hope you find the program useful.
