Looks like I solved it.? For future reference: 1. I installed MPLAB X IDS 5.45 2. I connected the usb to power the chip. Note that pin2 of the ICSP is NC. Since that is where VDD comes in, you need

Tried MPE IDE 5.4 and 6, they can report a bad id for the the 1454, but are able to erase it. When I try to program, they come up with an error that expected byte didn't match. The IDE's both say

Hi, Marek. The ATU does not care what SWR at tuning process time. The minimum power should be 1 Watt and more for tuning .

Hi,wheres the best place to buy the ATU-10 from and also what wire length is required,power consumption and also is there any 5V relays for the ATU-100? Btw im in VK

Marek I can't answer all of your post as I don't know the tuning algorithm, but from my testing of the ATU-10 it requires about 0.9 to 1.2W to tune according to my watt-meter. vk3pe

Hi All, I am using ATU-10 with my homebrew mcHF QRP v0.6.3 which has SWR limiter setting to protect finals. I find that during tuning process actual SWR from ATU presented at mcHF exceeds limiter

I have two ATU-10's from ALiExpress. I don't think the seller matters. They all look like they came from the same manufacturing lot. The first one I got was DOA. The second one seems to be working,

Thanks, Dave, for your efforts! I've got the *microC for PIC* , will go on in the author's IDE.

I thought hison was in this group at one time. If he still is, maybe he'll chime in. Vince - K8ZW. -- Michigan VHF Corporation -- nobucks dot net K8ZW - http://www.hamradio.fun

Ebay. Seller hison-818. Yes pre-built. I looked inside. No way I'm getting in there with an iron, let alone my fingers. I'll send him the review...

I'm assuming this is a pre-built unit from aliexpress? Cold solder joints, apparently. /g/ATU100/message/871

Hello to the group, Has anyone with the unit seen it seem to not be able to tune out more than a 2:1 mismatch. Rather it just passes it through to the transmitter. So it presents 2.5:1 or 3:1 at the

Hi Ian, Great find.? Thanks.? ?It looks like I did not push the latest MPLAB project file, which lists uart.c as a source file for the project.? So without this, it doesn't know to include

Great work Dave, I had doing something like this on my project list for about the last 18 months!.. so it probably never would have happened..... I did have to add a?? #include "uart.c"? to?

Hi Ellis, I am interested in an ATU-10 board. Which PIC's are used on the board? Details of price please I have built the ATU-100 kit and have VK3PE BOM downloaded. Just got a QDX so will be ideal for

pushed bug fix, and added UART to normal mode, and moved uart to Auto button for WA1RCT mode

I have this variant of ATU-100. I was working all fine for a couple of days and suddenly it decided not to charge anymore. This model doesn't come with any dc power supply, hence I am stuck with the

OK Scott, My post was more in line with getting the 1st unit working. Glenn

FYI, I found a small defect in my code, caused by the MikroC compiler ignoring case, and in a subroutine with the passed in parameter being "swr", and in the code in some places they reference 'swr'

After taking another look at that schematic, they didn't show the wiring to the fets for the relays for pins 11-18 whereas the ATU-100-ext version does. You can safely ignore my previous comment :)
