Re: Is it really working completely?
#atu-100
Hi John
I had a similar problem on the capacitor side of the tuner. I used my NanoVNA on SWR mode and stepped through the entire capacitance range using the test mode, this isn't measuring anything in particular but you will see if the expected result of a step is proportionate and in the right direction, this revealed several "holes" in the range. This was due to the following faults
1. Cracked and open circuit?
2. Relay not operating due to faulty driver FET
3. A plated through hole that was faulty.
With the inductors it's difficult to see if they are being shorted when they should be bypassed DC wise. I took out all the inductors (and cleaned off a bit more enamel) and checked out all the relays, then replaced the inductors.
Good luck, you've just got to be mehodical.

Re: Programming & compiling from github source code
MCC is an plugin for the mplab ide. It can be installed through the ide environment.?
It's pretty nice actually because it installs the required code plus headers when you select for example IO ports, Display, i2c etc.?
Through the MCC application you select what you would like to use. You select it's default configuration and when completed you generate the c and header files.?
It's here where you can for example create the alias for a pin. Including all possible usages as methods.
Best regards Onno
I am using the free MPLAB XC8 compiler from microchip.??
I am not familiar with the MCC tool.? Can you tell me where you got it from?? Is it MikroC?
Also, I'm still working on the DEBUG mode.? I am working on turning on the DEBUG flag so that the MPLAB XC8 simulator will display messages on the simulator screen when you enter functions in the code.
I am not familiar with stringtext29.??
Thanks for checking this out.? Together we will get it running.

Re: Programming & compiling from github source code
I thought I posted 2 xml files from the nbproject folder.? I'll go double check, and see if I missed anything.

Hi Glenn,
Exciting news indeed! Is it possible to get one here in the US?
Let me know.
On another note;
The board you sent me does not have the MCU. It looks like one
was installed but either taken off or somehow fell off (Which by
you soldering technique, is not possible). Was there a problem
or did you need to cannibalize it? Just curious.
I look forward to hearing from you as the larger spacing pitch
is much more preferable for these tired old eyes.
Or¡ Are Gerber's on the horizon?
Take care and thanks for your work. It is a valuable service you
are offering to the Amateur Radio community!

Hi All,
I made a pcb version that swaps all the 0603 sized parts on the
ATU-10 PCB to 0805's.?? Maybe still not 'big' enough to satisfy
those hesitant about smd work.
I received the PCB's a few days ago and have not loaded
one yet, but the Sch is identical to my previous
versions.
Details below, what is different
about the V1.31 ATU-10 PCB by vk3pe, over the V1.2 that I
released gerbers for.
- As before this
PCB is modelled on the original by N7DDC.
- All resistors
and capacitors are now 0805 size (were mostly 0603)
- 4 mounting holes
added if builders want to use a different case.
- PCB still fits
into three sizes of extruded aluminium cases. Ie 100x71,
100x82, 100x88mm.
- ? Alternate holes
provided for BNC sockets with 10.05mm pitch ground pins (Vs
6.6mm original)
- Top pads added
on unused Port pins of the PIC16F18877. (no current use)

Re: Chinese clones - not working as expected #ATU-10 but a great ending
#ATU-10
As someone mentioned, it sure looks like the kits are identical, at least for the most part.? So I have a feeling that 9 out of 10 sellers probably have no idea what they're selling - they buy in bulk and sell one at a time for a few dollars profit.? So identifying which seller is better than another is mostly impossible.? It comes down to how well they look after you after the sale, if you have a problem.? I learned this after my first ATU-100 purchase, which is still being dealt with several months after the fact.
I ended up buying a second unit from Hisonauto, who might be the same seller you mentioned.? This was after the first project I mentioned from a different seller exhibited odd behavior.? I exchanged a few messages with Hisonauto and decided that he has technical knowledge.? I wouldn't doubt he's also a ham.? His kit used axial Schottky diodes instead of surface mount and when I completed the assembly, it ACTUALLY WORKED!! ;-)? So I would agree that Hisonauto is probably a good bet when sorting through the many sellers on Aliexpress.? I would deal with him again.

Re: Chinese clones - not working as expected
#ATU-10
David,
I did touch up all of the relay solder joints even though I could not see an obvious problem with them. I noticed that the leads of the relays do not really protrude from the bottom of the board, so it would be easy to think you have a good solder joint when you don't. However, the tuner still does not work.
The screen lights up and the tuner will go through a tuning cycle, so the main PIC appears to be working. However, I can't load any test firmware because the tuner does not show up as a drive on my computer when I plug it in. I tried it on both a Mac and a PC.
I'm not sure what you mean by oxidized nodes of relays. If a relay is bad, replacing it will be challenging because the fabricator used lots of glue on the coils, relays, and batteries.
Unless we can show that there is a difference between vendors (which I doubt), I can't recommend the Chinese clones at this time.
73,
Scott

Re: Programming & compiling from github source code
I have? downloaded the WA1RCT code (Thanks David!!!). Unfortunately I cannot compile it and I expect something is missing. I have used the MCC tool to create the environment and with this the compiler works and I am able to program the PIC however no intelligence included on the actual firmware. Its just a test environment. I will try to copy the code to my code line to see if I get it to run however the references are very different.? Can you share more information David on your environment? Thanks Onno

Re: Programming & compiling from github source code

I couldn't find a way to open the project in MPLAB X IDE, Should there be some project related xml files in the nbproject folder?
Also, couldn't find im?lementation for the softI2C or isn't that needed?

I have created a git repo with my code.? ?This has NOT been run on HW.? So this is simply an early peek at what I've done.? It is located at:
I forked David F's code, but replaced it all with mine, in my repo (which does NOT touch any of his code).

Re: Programming & compiling from github source code
+1 what Onno said.
I have an AT1000 that I successfully upgraded to 3.2. Just make
sure you copy out your eeprom values before doing the upgrade.

Re: Chinese clones - not working as expected

Hi, Scott
Other people report about up to 3 not soldered properly relays in one Chinese atu-10.?
The problem is in oxidized nodes of relays, that is not simple cold soldering.
I will improve the test firmware soon to help to find those relays .

Re: Chinese clones - not working as expected #ATU-10 but a great ending
#ATU-10
Many people in this thread have gotten a defective ATU-10 from Chinese vendors on eBay/AliExpres/....? These have quality components but bad manufacturing (cold solder joints etc.). I too got one of these bum units from eBay.
BUT, here is the encouraging story: The seller hison-818 was absolutely great to work with. We went through and ruled out user errors, he understood my configuration in which I was testing the ATU-10 (Rig to ATU-10 to a known good Dummy load with plenty of power capacity). Within 1 day of triaging the problem, he dispatched a new ATU-10 after locally testing it in the same configuration. I received it yesterday (5 days later), worked perfectly. Last night i WSPR'ed on multiple bands with plenty of hearing k1jbd reports on WSPRnet. He did not ask for any additional charges, postage or even to return the old unit (which would be very expensive from US to china from a postage point of view).
Based on the above I can highly recommend hison-818, a honest vendor, who has excellent customer service and cares about the customer.

Hi
Finally have this faulty ATU-100 repaired... and what a mess it was!
The following is offered in the hope it will save others some time and energy.
The original fault symptoms which seemed to originate in the SWR detector bridge was due to a subtle disconnection in one of the sense windings which was resolved by rewinding the whole bridge.
The ATU would still not tune reliability, if I touched the output of the bridge with a multimeter probe the ATU tuned after a fashion. It appears the SMD caps C18 and C19 are either faulty or too low in value to decouple the bridge output. I replaced them with the only SMD caps I had to hand, 223's which seemed to do the job.
The tuner still did not tune properly, I used a NanoVNA to connected to the RF IN connector to establish that the capacitors C1 to C7 were not being selected in increasing order (using the tuner in TEST MODE)
Briefly the faults were as follows.
C6 470pf burned up on applying RF
C3 47pf? cracked and open circuit
C7 1000pf cracked and open circuit
Q9 faulty and not operating relay S12 to select C4 100pf
C7 not being connected when the relay S15 operated due to a missing plated through hole...replaced by a wire.
Combine this with the original faulty display and wires continually breaking off the front panel switches, it was a bit of a Friday afternoon job...literally!
A pretty poor show for a ready built unit.
I wonder if anybody has a source of the 47, 470 and 1000pf caps (silver mica 500v low loss)? I'm just using some regular small caps until I can find some replacements.
