Re: ATU-10
Trent Trent
I want to have it so ove got some distance between the radio and the atu due to location of a setup and style of setup Also David is there any ppace where I can buy a original atu-100 from as I've had 2 from china stop workin for no reason On Sat, 19 Feb 2022, 3:14 am David Fainitski, <rolin791@...> wrote: Hi, Trent |

Re: Programming & compiling from github source code
Has there been any further progress ATU-10? on moving to Arduino IDE. ?
I wonder how hard would it be for those looking at this, to add an option for an 8x8 tune set, rather than current 7x7?? (I'm looking at adding the extra cap/inductor relay switching to my version of the ATU-10 PCB.) Or maybe David, N7DDC,? might look at this possibility in current Mikro-C code. Glenn vk3pe |
Re: #atu-100 Updating firmware can a USBASP be used?
#atu-100
See
The USBASP was made for Atmel AVR micros.? Not all Microchip PIC micros can be programmed, especially the fuse bits. |
#atu-100 Updating firmware can a USBASP be used?
#atu-100
I have a USBASP? V2.0 used to program chips in my QRP Labs rigs, can this be used to update firmware in my ATU-100's?? If so anyone know how to connect pins?
Thank you? 73? Emory? WM3M |
Re: ATU-100 Auto switch does not work?
#atu-100
Never mind, had very small solder bridge between the two pins, even under my strongest mag could not really see it.? But got it off with very small blade, works fine now. |
Re: #atu-100 Upside down display?
#atu-100
Appreciate the help.? I have not tried changing or doing anything with the firmware but will do some research and see if I can do it.

ATU-100 Auto switch does not work?
#atu-100
New build of ATU-100, works fine but Auto switch does not work, both bypass and auto show _ underline on the display and both turn it off but can't get into auto?? Any suggestions or help would be greatly appreciated.? Its a recently bought kit and its version 3.0.? Only way to get it to tune is to push tune button.? Thank you? 73? Emory? WM3M

Hi
You can do that by changing cell 01 with values 04 or 05 |
Re: ATU-1000 Assembly Instructions Needed
Sorry about the duplicates folks, thunderbird kept saying it couldn't send and was retrying. Good thing I rebooted or who knows how many times it would've retried!

Re: ATU-1000 Assembly Instructions Needed
I haven't finished putting it together yet, I got all the inductors done except the two for the SWR yesterday. Things keep coming up but I hope to get it finished this week.

There were two vendors on ebay that I saw with the same kit, one of them (hison) is or was in this group. Both have said that they're aware of the bad Chinese toroids and have switched to others. The one I got (not from hison) said he imports the cores from Germany, so I went with the ones included in the kit. If I have any heating issues with them I'll be ordering some new ones from either DIZ or Mouser. I haven't really looked into max power yet, although I did see some youtube videos where they were putting well over 1KW thru it. I would think alot has to do with the SWR of the antenna without a tuner. Supposedly the current units have the latest firmware, I guess I'll see that sometime this week too. That should actually happen before I put RF into it since I can power the PIC board without the tuner board connected. I also got your direct email so I'll be sending a separate reply there shortly.

Re: ATU-1000 Assembly Instructions Needed
Vince: It is a Chinese kit with the SMD already mounted. I would be very happy to receive the instructions! My email can be found on QRZ as W1LJ. Since you have built one, mind if I ask a couple of questions? 1) Did you toss the Chinese toroid cores and buy new US-made ones? I've read that the Chinese core materials are NOT the same quality nor the same permeability as the USA specification ones. 2) Did the unit work straight away after you built it, or did you have to upgrade the firmware, or do any other modifications to make it function properly? 3) How much power have you put through it ? I'd like to use it on FT8 at a maximum of 400W output. The general rule is that an auto tuner can handle approx. 1/3rd of it's SSB/CW rating when used on FT8. The later ATU-1000s were supposedly upgraded to a 1.5 kW SSB/CW rating from the original EU2AV design, which used less ferrite in the inductors. Any comment on that? Thanks for your help!?
