I'm working on extra features. I've got a codebase that builds/runs fine with MP-LabX / xc2.40. I've not pushed anything to git-hub, so will probably push something up on a website somewhere, I've

Hi, I have some modifications planned on the ATU100 to add an Arduino. I need to modify the source code to include an I2C master mode output to communicate with the Arduino boards. I've never

Hello everyone, I recently completed the eBay 1kw version of the kit and immediately realized the SWR bridge is extremely out of spec. I’ve tried adjust the potentiometers to no avail. The power is

It reminds me to the Tandem Match. Nothing wrong here, this coupler type is eassier to adjust, actually there is no adjustment, it should work properly "on the first good one". Bruene type coupler

so martin,what is the one i posted pics of?.

wrong! Correct schematics of Bruene (Warren B. Bruene, W5OLY (SK), initially used at Collins) and Tandem Match (Stockton GM4ZNX) are attached. Both have some pros and some cons. Two separate toroid

Tbh I don’t know. Hopefully someone else can help david M0TGC

thanks david,its for a homebrew L match atu ive built,i want to fit twin needle meters to it,ive built 2 atu-100 kits,so far both have blewup,ive given up on them and am using the homebrew lmatch,it

This: https://www.qsl.net/zl1an/Downloads/Bruene_explanation_V13.pdf shows two windings each connected to ground and winding in opposite directions. What is the project that it is for? David M0TGC

I am trying to build a dual bruene coupler for a project, All the ones i see use 2 torroid coils with about 12 turns on each with the main wire coax thru the coil center with one side of the coax

Have you tried changing the code and recompiling? I had a similar issue but luckily I found the sw vs SW issue which the compiler does not flag.? Until I changed the sw variable to another name it

Hi, David Thank you, but it is not a reasot to run it continiously. Technically SWR goes to near 1 as I can see on the transceiver, the question why the alogorythm doesnt wanna stop. With other load

One possible reason is in the routine: int testSwLC(char sw, char l, char c) { SW = sw; ind = l; cap = c; Relay_set(ind, cap, SW); Delay_ms(5); get_SWR(); return SWR; } The SW and sw variables are

Hi, Tom I tried your algorithm on my ATU-10 and my resistive load. With 200 Ohm load your algorithm goes by cycle continiously. I see on the transceiver display that SWR goes to near 1 but the algo

Thanks for the build DF. ?This first algorithm is really a proof of concept of the GitHub project testing platform I created. ?The test platform allows easy testing of tuning algorithms and

Hello, people Tom Court developed a new algorithm for us based on deep mathematic analyse you can find his job here https://github.com/tomcourt/tunetest Also, as you can know, I wanted to implement

Hi Tom & David Wow! This algorithm (tune2.c) works very well on my ATU100/1000! It achieves good tunes on my three test bands 40m/60m/80m, as good or better than my most recent algorithm (recently

It's gcc running on a Mac in a simulation (think a simplified version of SPICE) running a bunch of tests. The project is at https://github.com/tomcourt/tunetest It should run on a PC or Linux if

Hi Tom What compiler are you using for tune2.c? I have a minor issue of case sensitivity using mikroC concerning swr in the hillClimb routine .? It compiles now and making the wag arrays const has
