Re: ATU-100 spares

#1824

Previously I think the switch shorted or grounded a resistor. I tried to copy these connections across to the new board but I didn't get the same behavior?

?as before. Maybe a minor revision of circuit board?

I think I have some pictures of the original setup

Thanks

John

Hi John
Thanks for getting back to me
Yes i would put a switch on the battery wire, how was it done before ?
Thanks for the info, i have just cut out the front panel of my case for a large display, and i got a bit carried away when i ordered a battery for mine
i was going to just get a 18650, but i got a 10Ah battery as it is only 12.5mm 60x100 and should fit in the case that i am using,
Thanks Dave 2E0DMB??

Hi Dave

?

I don’t recall any RF noise with the old setup and as of yet, I have not re-wired the new board back in successfully.
I did try and wire it in using the same setup as before but didn’t appear to work as expected. I am thinking of adding an extra switch to power off the ATU by cutting the power from the battery rather than off the board.

Hi John
can you please tell me do you get much RF noise with this Board, as i have just ordered one to go with my ATU-100 that i plain on using with my clansman prc320 radio
and my X6100 when using a 45w amp,
Thanks Dave 2E0DMB

Re: Power and SWR reading are wrong on upper bands.

Hi YO8SEP
I know it has been some time
how did you get on with this, i had the same problem and it was the diodes that had been fitted had to be changed to BAT 41,
when i put this info on Davids's git hub, a few more users tried fitting the BAT41 then there tuners worked fine
Thanks Dave 2E0DMB

@ David: your'e so right! I forgot... (by the way: thanks for fine work!!)

@ Amanda:
and now from PC I add some pictures:

The connectur at the pcb (regard the colors!)

PIC-3 and his conector

How to put the prgramming cable to the PIC (regard the colors! Black is Pin 1)

During programming the power supply of the tuner has to be set off and the display has to be disconnected. The processor is supplied from PIC3 during programming.

Joshua, I bought my true uSDX from them. Sunny at diytech was very responsive and the build I received was very good. Did you receive your ATU 10? If so, your impressions and evaluation? I'd be using it with my uSDX. Thanks, Mike WA1MAD

does anybody have a simple description of which connections go to where with regards to connecting the pickit3 to the oled connector.

Hi, 
If it’s any help I bought a non working commercially built ATU100 off eBay, the toroids were adrift from the board at one end, after resoldering the unit was doing strange things, then I realised that the the input and output were labelled the wrong way round on the back panel. Something to look out for?

PCB Orientation of T1 T2 Binocular Core

#1807

Once the T1 T2? binocular core is wound, does it matter how the 10 turn wire ends are oriented on the PCB? (Please see attached YT screenshot vs my connections) I'm having problems with an AliExpress ATU100 kit not indicating the proper power output and SWR. The kit came flashed with V3.2 firmware and seems to go through the "Test Mode" and "Fast Test" without issue. I'm aware of the potential problem with some Schottky diodes and possible poor solder joints, so I inspected all solder joints under a microscope and they seem fine. Finally, what is "Fider Loss input"? and what it be set at?? Any help getting this working right would be greatly appreciated!

Hi, Stig

Disconnect the soldering pad jumper and try again with disconnected relays switches.?

Re: ATU-10 3x more DC Current in SLEEP & OFF ?? #ATU-10

#1805

Hi David.

Yes, on the jumper pins, the 12 mA with the display light, oís OK.
But in all other conditions, it is the same, as 37 mA.

Re: ATU-10 3x more DC Current in SLEEP & OFF ?? #ATU-10

#1804

In working mode 12 mA

Waiting mode 0.17 mA

Power off - 0.037 mA

You can meter a current between a jumper on the board and soldering pad jumper to recognize what is taking power MCU or switches parts.?
