Good kit supplier for Europe ?

 

Hello all,

I am a bit confused by the dozens of offers one can find on internet for an ATU100, is there a "trusted seller" that you would recommend ? Alternatively, are they all good or are there suppliers to definitely avoid ?

Also I want to double check, is it OK to operate the ATU remotely ? It is to put on a boat so the ATU will be below deck where the antenna exits which is hard to access, the plan is to simply switch on the power supply before operating and to let the ATU do its work.

Re: Chinese clones - not working as expected #ATU-10

 

I’ve spent too much time on fixing them. The problem is caused by cold solder joints. The first one I ordered had cold solder joints on the relay of L3 so it could not bypass L3 to achieve low swr. Another issue is the pcb is too wide for the case so it’s extremely hard to attempt to fix. A few weeks ago I almost fixed all the issues to make it work perfectly, then ESD destroyed the MOSFET of relay for L7 so it became useless. I then ordered the second one. Today the second one arrived. Unfortunately it had similar issues. Swr is 5+ with 50ohm dummy load. The seller told me he tested before shipping so I think it’s cold solder joints again. I think the seller/builder doesn’t know how to do proper soldering. It’s a such a pity as the seller seems to be sourcing high quality components for building it.?


Re: Programming & compiling from github source code

 

Hi Dave!

This sounds great and I really look forward to this project!

------
The approach really depends on one very important thing. Approval from the repository owner who wrote the software. I assume it is David F. but I am not sure about it.
------

I have experience with assembly and pic controllers. GitHub I am using almost daily for my work developing java backend applications. Programming with C is not a normal environment for me but I expect it will come back pretty quickly.?

I have a pickit 4 and I installed the ide and ice application. Both work well on Linux. Also installed the MCC plugin which is a great help to built a C template for config and pin assignment.?

Regarding git we could clone / fork the project or create a new branch from master to another branch with a name representing the work. Latter permission is needed as far as I remember using a public repository.?

I just want to make sure we have the approval from the owner of the original code first.?

Best regards Onno

I agree with David F that we will have to replace the library functions.??

Question for David F:? Would you be interested if we did this in a way that allowed the sources to be built under EITHER tool chain?? And then we could avoid forking the source tree (based upon the tool chain)???

While I agree the MikroC version would work 'as-is', it costs $250 just for the assembler/compiler/linker.

Re: Programming & compiling from github source code

 

Onno, Dave & David F.,

I was thinking of implementing the code for STM32 and Arduino. Especially?STM32 is close to my heart but Arduino would give a very easy development with no programmer needed. Arduino framework is also available for STM32 cpu's.

So would it be beneficial to try to port the code to plain C that would compile in many environments with some preprocessor magic?

Hi,
I made a 1500W tuner according to the EU2AV scheme (PIC 16F1938 processor).
David N7DDC firmware based on old version 2.7.
Question for David,
is it possible to do it on software version 3.1 or 3.2 and display the correct power value?

Re: Bypass mode behaviour & high SWR on 6m

 

Hi David,

OK, understand the string length, can you reveal where it can be changed ?

RR re SWR on 6m , I fixed mine? - I found the one of the SO239s on the back panel was slightly loose.?

thanks

You can change the prescription ATU-100 trough a hex changing but you can not add any symbol more in that string.
To All - 1000 W version is much larger physically , has different relays and has larger own L and C values so SWR will be larger too .

Re: Programming & compiling from github source code

 

Hi David,

I understand it's easier to use microc ide because that's the environment used for the original program.?

Unfortunately the cost associated is high. Combined with a pic 4 programmer I would arrive at around $350 and that's a lot for a small hobby project.?

I have used pickit 2 in the past and wrote assembly to program pic controllers. At the time I also looked at microc and learned it only worked on windows which for me was another showstopper. I don't have windows.?

Best regards Onno

Hi.
You have to change some specific built in functions like Button , ADC, Conversion.?
Also pic configuration and ports settings.
Nothing difficult but it can take a time.
Better use MicroC IDE.

Chinese clones - not working as expected #ATU-10

 

So,
? ? ?after reading about this particular design i stumbled over various stores selling supposed clones of the design. As it suited my needs and my price point i pulled the trigger and ordered one. The device itself seems to be well constructed however it simply does not work as you would expect and fails to tune well even with a resonant antenna. Now I should stress I am not a constructor and my soldering skills are not of the highest quality so I would have no clue how to diagnose the problems with the units. However I have ended up with two of these and would dearly like to get them working. If there's anyone in the UK who might have the skills I'd be happy to send you my two units (yes I've got two of them) to see if the issue can be determined. In return I'd be happy to let the other party retain one of them for their own use.?

If anyone wants to take a look let me know.

thanks
Adam. (photos attached).

Hi

You probably need to give more information. It's often difficult to diagnose remotely, any electronics.

At least what PCB are you using, software, what exactly is the problem, etc.

Re: Programming & compiling from github source code

 

Ok understood. So the code relies on embedded functions as offered by the microc compiler environment. Unfortunately this makes the code difficult to use with other compilers.?

I will check if I can write similar functions such as button debouncing and using the i2c interface. Most is provided by microchip ide too but I need to search and learn first.?

Or i strip of all the button and display stuff since I am going to use it for remote tuning only.? Simplifying the code for it's purpose.

I am grateful this tuner got developed and code has been provided through GitHub. It gives a good start to learn.?

Thanks and regards,

Re: Bypass mode behaviour & high SWR on 6m

 

I don't have such high see on 50 MHz.

Bypass relay is normally closed and with power off swr is 1.1:3. When power is connected and unit switches to bypass the relay is closed too.?

Tuning on 50mhz also works well with a random wire about 10 meters long.?

Perhaps I have a different version.

Hi David,

OK, thanks - the Russian 1kW unit purports to operate to 6m and it does tune there nicely but the through SWR is higher than it should be.

A question for you... Where in the hex is the string "ATU-100" stored ?

I'd like to change mine to "ATU-1000" to match the tuner if possible.

Tim

That is normal behavior, because on my tuner this position of C switch relay gives better SWR.
Please keep in mind, ATU 100 tuner works well on 3.5 - 28 Mhz only .
