I got the ATU100 kit from china and put it together. When I use it on either ~60W or when the SWR > 5 the mode seems to change randomly as I transmit. Not sure if its RFI or a software issue. I have a

Mike, if I think so, this is the one-button Chinese version of the ATU-100. They put this little panel in them, I don’t recognize what it could be. A few notes: *if you see a USB connector, you

Well, it looks like the 8 pin IC took the easy way out.......burnt up! I just bought the device and plugged it into a 12DC supply using the front mini-usb port. I have been pouring over the schematics

I have the exact tuner. No charger came with it and it will not charge with ac 12v charger. Don't see any responses..... Mike

Hi, Have on order one of those ATU-100 "kits" from Amazon (Malahit ATU-100 7x7). I read where c1-c7 are ceramic instead of the original silver mica 500v and there was some concern expressed by at

Hi Onno, where i can find pcbs or gerbers files for ATU1000 ? Thanks, 73 Luca IK2LRN

So an update here.... The ATU-10's OLED stay lit until I drove the battery down to about 3/4. Then it started acting like specified (oled turns off after 5 min, quick press to re-light, after 40

Buonasera, ho assemblato anche io un atu1000, e non ho il firmware 3.2 lcd, l unico che funziona correttamente è la versione 2.7 riportata sopra, chiedo aiuto a qualcuno piu esperto di me in merito,

Hi Kevin Jo may be right.? Read the pic (program and eeprom) and then see what the config bits say.

OK I've found a solution, using X IDE, see attached for details. Hope this might help others struggling to use the PICKit4. Kevin - M0KHZ

You might be able to do that with a TL866 It doesn't work with all chips. Which one is it? Jim ? G4EQX

Hi Jo I'm sure my config bits are set correctly, see attached... What every I try to do the eeProm data is not being changed, I'm probably doing something really stupid but X IDE and PicKit4 is all

Hi Kevin Isn't the eeprom write protected? This means you will have to clear the PIC and data first and then re-program it with the protection bit unset. 73 de Jo PG4I

Update This method doesn't work after all.... Still working on this issue ..... Kevin - M0KHZ

Hi All So I now have PicKit4 editing the eeprom data, I had to change the project configuration to disable re-writing of the eeprom data, see attached screen print. So the full sequence is as follows:

I’m currently building the 7x7 PIC16F1938 version. I am using a PicKit4 for programming, and have no problems programming the latest firmware. However I can’t edit the EEPROM contents. Within X

I guess the Ukraine boat has sailed for me and others, oh well, snooze, you lose... Just have to rely on the ol' AT-1000 Pro II. My intent was to put the ATU-1000 at the base of my 43ft vert. John

Thank you, Dennis, you just saved me some cash, I've been hesitant to pull the trigger on this thing, now I won't. Thanks again, John VE7KKQ [email protected]> wrote:

Ah yes, John...sorry! So very dense of me to not figure that out! If one scrolls way far down...the assembled version is down there. A word to anybody buying the Chinese tuner: the powdered iron
