Hi, Paul. This message is a pinned message, one of the couple other pinned messages wich are very important and helpful for nubies.

It will work with the 1602 display

I think it still only uses the top two lines and I think it may have to be 16 characters see https://www.youtube.com/watch?v=vWtbs4n4ewo

why is this always at the top of the page?

would a display like this work with the ata 100,ie four lines or does it need a 2x16

Hi, Rod Just in case the board has pads marked R , for reseting MCU but re-install FW is easier way to reset.

I decided to try reinstalling the firmware v1.6. Voila! It's back to normal. Is this a common occurrence with these devices, that there's a software glitch that just requires a reset

While tuning up today, my ATU-10 has frozen up, meaning the screen is stuck at PWR 0.00/SWR 0.00. The button will RESET the tuner but it then just buzzes quietly and goes back to the PWR/SWR

Aaron, Try pressing the Tune button until you get the SWR=Tune for the dummy load, then apply RF.? I believe the logic assumes you have the same antenna connected for a given frequency, so it does

Evan is awesome, he has saved my shack more times than I can count. I believe that I have it in TUNE mode. Now it says: PWR:9.9W SWR:5.3 ATN: 4.5W EFF: 84% I can hear a relay kicking in when I

Hi Aaron, I am not stalking you intentionally.? You are asking questions on the groups that I read almost daily.? I am retired, so I have a lot of time available and a lot of interest in

Hey Evan, are you following me lol I'm not sure what mode it is in

Aaron, Are you sure the ATU is in automatic mode?? If in one of the other modes, it may not tune regardless of the mismatch. 73 Evan AC9TU

hi Aaron, the use of a piece of coax of Z=50ohms to a resistor of 33ohms will result in SWR greater than 1.3 and should initiate a tuning to SWR better than 1.3. This a functional test for the ATU.

With a 50 ohm dummy load it is showing the exact same thing. I really don't understand what you want me to do with the coax.

hi Aaron, what shows the ATU if you send to a dummy? It happens that tuning fails if the SWR is too high and no match is possible with the existent components. For testing use some yards coax to a

Hey guys, I have a ATU QRP-40 ATU. It is pretty much the same as the ATU-100 but it maxes out at 40 watts. Here is my setup: Rig: uBITX ATU: ATU QRP-40 Ant: Endfed random wire 35' with 9:1 UNUN When

Bad soldering of the pic nodes, shorts on the path, wrong soldered button position. Disconnect the button and check shorts with multimeter, power is off. If no shorts, power on and check the voltage

i did. no voltage to the bypass one , and it goes to zero on the auto one when pressed. there is just no B+ coming from the pic , none at all for the bypass.

Thanks.? Got it. 73, Hugo.
