hi Elijah, for correcting the display, look for the cells 7 and 8 on EEPROM. Try setting both to 0 (zero)... that may solve this issue. 73, Immo

can nobody id what type of coupler is in the pics i posted?,it is from an old avair 1000 swr meter that had an open meter movement,the coupler is from 1.8-150 megs,the uhf is a seperate item.

Hello Geoff and others. I successfully erased the protected chip and uploaded the new firmware with some corrections. It took me a while and numerous times of trial and error…but it at least turns

I've developed an extensive test framework for comparing both how fast and how well algorithms perform using a simulated matching circuit. I've commented the code for my newest algorithm to some

Hi Singleshare, I've just joined this group and your message solved my problem with an ATU-130 (similar to the ATU-100) that wasn't tuning. However, in my case it was operator error. I had plugged the

Hi, Chris, I don't think the Г shaped matching has multiple minimum SWR combinations. I think there is only one in ideal condition.

A word of caution. One can find the fastest match or one can find the best match. I suspect the two are not the same. It is possible for a tuner to have multiple combinations of L and C where a low

Thanks David Regards

Yes , the Chinese clone is a little bit better then original , so 3.5.

Dear all, I was thinking to buy a pickit3 and looking for it i've seen the pickit 3.5. I have not find info about it and my doubt is, Is the pickit3.5 compatible with the AT100 as the pickit3? Thks

Hi Roger, Thanks for your answer. I am very satisfied with the operation of the current Firmware of the PIC16F1938 and in general of the ATU1000. My interest in modifying the PIC programming is to

Hi, Its all on the Github page. Download the user manual, and look at the last few pages, where it tells you what cells do what functions. I changed the display settings, and the turns ration for the

I did some more reading and ordered a PICKit 3 this morning. I’m going to try and utilize the chip in the board but already have the chip and socket in my cart. I also found a document that

I've just done this. David helped with me understanding which cells to change. I got the 1000w atu from Aliexpress. They soldered in the chip, and blew the read fuse.I would suggest you cut the pins,

Elijah, you need to erase the PIC , flash the latest FW with corrected cells. Many people did this before, nothing special. I don't know why Chinese s manufacturer closes PIC, that is stupid.

Hi Please let us know how you get on with this tuner, Thanks Dave 2E0DMB

Thank you, I will keep looking in the group. I’m tempted to remove the chip and start all over from the ground up…but that is probably overkill. I bought the kit off of eBay from china and suspect

Hello gentlemen, I would also like to know your opinion about the ATU 1000, namely about how to correctly adjust that variable resistance, which exists on most kits and ATUs sold in China (and not

Hi. You have to change some cells according to tandem match ratio. You can use pick it 3 programmer and software you can find in the pinned messages. Cells description in the manual at the end.

What are the existing diodes?
