Re: Should ATU-10 wake from sleep when RF is detected?

 

Why not power it with DC through the coax?

Hi, Steve
You can increase the time up to 99 mins or disable switching off.
The power consumption in working mode - 12mA, waiting mode - 170uA, power off - 37uA.

Should ATU-10 wake from sleep when RF is detected?

 

Hi Group,

I have an ATU-10 that is mounted remotely near the antenna. I can retune it to a new band by sending RF provided the ATU-10 is on. But after 30 minutes, I can't retune just be sending RF on a new band. I have to go an turn on the ATU-10 again. Is this expected? I would like to be able to wake the ATU-10 remotely with RF.

I understand I can edit a hex value and set the ATU-10 to always stay on. How long does the battery last if it is always on?

I am running the latest 1.6 firmware.

73,

Steve

Re: fider loss

 

so why not call it coax/feeder loss,instead of fider loss!?.

Re: ATU 1000 High Impedance antenna random wire

 

Hi. I would like to ask the seller for a schematic, but you can follow simple ATU-100 schematic on GitHub.
The biggest should be 4.5, smallest 0.05.
If you make this bigger it will work better below 7 MHz but worse above 14 MHz.

Hello David

I cannot still try manual mode , but the best SWR is about 3 worse 9,99

On 50 ohm load all work fine .

Now I've disassembled the inductors I should rewind them
which values I must use ? how much should the inductance be bigger, before I had 6.4, is okay?

Regards

NEX

Hi.
Did you try a manual mode ? Can you reach good SWR with it ?
What is the L and C values when you reached the best SWR ?

ATU 1000 High Impedance antenna random wire

 

Hello
In a previous post David advised me to check
?
1) Activation of all relays
2) Inductance values
3) capacity values
?
I followed his advice and changed the Stockton to a commercial one but still having the same problem.
?
The readings are correct but the tuningt is not complete, it always leaves a lot of SWR on almost all bands, but it's fine if I put a 50 Ohm load.
The maximum inductance value is 6.4 ?H for a total value of 12 ?H this value must be increased as the post below says?

Has anyone solved this problem?

Re: can someone advise me on this please?

 

hi Paul,
?
reading all your posts, I can say following:
You are using a functional setup for PIC Kit programmer. (Is it PicKit 2- ??)
You are using the actual firmware 3.2 for the ATU100 (checksum DFB6 is ok, config number 3FC4 1233 is ok)
?
To program the 16F1938 you should chose at??Tab Tools -> Target VDD Source -> Auto-Detect
So you don't have to care wether power of the ATU is ON or OFF.
?
Disable Code-Protect and Data-Protect (Ctrl+P and Ctrl+D toggle the settings)?so you don't see the confirmation in red color : 'All protect' or 'Code Protect'
?
You might take a look, if on your I2C-adaptor for the 1602 LCD-Display are no bridges soldered like Dave (Hello Dave!) showed.?
Then you have to load the hex-file to the PIC Kit and adapt the values to your choice:
LCD 1602 with standard I2C-bus adaptor: Cell 00 to 4E, Cell 01 to 01

?
Follow this: select the desired cell with left mouse click, it turns to blue background.
Enter now simply the new value and deselect the cell (by chosing any other cell)
?
You don't need to push the enter-button any time...

After this you can program (write) the PIC.
?
After the ATU is powered ON and only the background of the display is lit, you may adjust the contrast of the LCD by turning the poti on the adaptor-pcb. But do it slowly, the right point is quickly overridden...
Now you should be fine with your ATU.

(If LCD is not recognized, try cell 00 with 7E instead)

If you like, for additional knowledge look to my posts:

Re: can someone advise me on this please?

 

Hi Paul,

Have you checked that the 1602 display is working on another project such as the Arduino and if so what I2C address was it using?

What is the setting of the A0, A1, A2 straps on the I2C adapter board, since this will dictate what I2C address needs to be used?

Re: can someone advise me on this please?

 

heres a screenshot after programing,still a blank led screen tho.


Re: can someone advise me on this please?

 

Paul,
You need to
- Select the 7E and change it to 4E
- Select the 05 and change it to 01
Then write to the PIC.
73, Dave


Re: can someone advise me on this please?

 

dave,its the one too the left of where it says 7E on the pic you posted,the one that says 00,it just goes blue and i cant change it then,have you a pic of what it should be to work with the led?,so far nothing i tried makes it work with two 1602 led + ic2 boards i have,it works fine when i set the 7E cell to 78 but only with an oled,nothing i do seems too work with the led display tho,.thanks Paul m3vuv 73.


Re: can someone advise me on this please?

 

Hi Paul,
Just to check when you say "yes but when i click on the 00 cell it turns blue and wont let me do anything", you are selecting the fields shown in red below.

73, Dave


Re: can someone advise me on this please?

 

Hi Paul,
If you was able to change the values to 7E, 05, you should be able to use the same method.
Alternatively if you program the device with the original?atu_100_fw_EXT_32.hex is should have the correct values for the 1602 display.

Re: can someone advise me on this please?

 

yes but when i click on the 00 cell it turns blue and wont let me do anything.73


Re: can someone advise me on this please?

 

Hi Paul, I covered this in my previous response in your other topics.

For the PCF8574T and the 1602 LCD you need the following:
EEPROM Addr 0 = 4E
EEPROM Addr 1 = 01

heres a jpeg,hope its better.


can someone advise me on this please?

 

Hi all,i am trying to get my atu-100 going with an 1602 + ic2 pcb working? together,see the screenshot of the pic program and tell me if its ok please .
