Hi, Randy It is definitely more then 1 sec now. About 3 sec, Short press for reset, 1 sec for tune, 3 sec for turn it off.

Hi, Randy That issue is not in the FW. Thats a hardware, interferences to the Oled controller.

I can only throw this into the mix; the only time I ever saw stuck pixels on the display was when I used my Apple Mac worksation to update the firmware. I now use a Windows VM and I've never had a

I have a new ATU-10 that mostly works great, but the static pixels, those that aren't updated on each transmission, randomly turn on over a period of time. I considered RF in the box and made sure I

Is there a place in the .hex firmware file to change how long you need to hold the tune button in order to turn the ATU-10 on or off? I would like to be more like 1 sec vs. 3 sec. If not, can this be

Hi From the text I assume that it is an ATU bought from the Chinese, with a built-in internal battery. The noise may come from the battery charging unit. If you can, isolate that unit and feed it

Hi. Replace that 5 volt regulator or check what is wrong with it. That is the interferences source.

My ATU-100 has all of a sudden turned into a noise generator.? It's spewing noise across the entire 3 MHz. to 55 MHz. spectrum so far as I can see by looking at the waterfall on my IC705.? It's not

Hi, Paul Ceramics type should be NP0 or X7R kind for ceramics capacitors or silver mica, 250 Volts or higher. The inductor should be with high Q on 30 MHz and does not have selfresonance in 0 - 30 MHz

the linked schematic doesent state the cap type,ie film or silver mica etc,any ideas what to use,ie type of caps?,cheers+73.

any idea what type of caps+ voltage rating?.

i want to mount my atu 100 on my mast,has anyone a schematic for a schematic for a bias t good for 100watt tx power?

LDG sells a balanced feedline balun, coax to balanced line, goodfor (I think) 200 watts.Not terribly expensive either 73 de W5ALX Alex Netherton http://blueridgediscovery.org

just make and fit a 1-1 balun.

Hi all I have a question: beside the unbalanced (sma pl) connector is possible to add a unbalanced connector?

Hi. A reset feature is the bypass or not ?
