Has anyone ever been able to get Xeigu x5105 to talk to the Loop Controller? I sure could use some help figuring out how to setup the controller for the Xeigu x5105 and how to connect the controller t

Hey, all. I have collected most of the parts to begin the controller. But the Teensy has been elusive. I'm not too hopeful for the timeframe given by PJRC for their return. Would anyone here have an e

Hi all, I am trying to compile version 4.10 but get the error message Compilation error: stray '\302' in program. After searching in Google I found out that this message appears if there is a weird ch

Hi, gathering all the parts in order to build the loop controller. As the 64-128ppr encoders are quite expensive I started thinking is it really not comfortable to use a cheaper 20ppr encoder? After t

I hope this is not too far off topic. Does anyone know if the Ukranian/Russian KPI Vacuum Variable Capacitor shaft bearings can be cleaned and lubricated? Mine is very stiff and I doubt a small motor

Hello, I am planning to build the loop controller and a magloop antenna for 20-17-15m, max 100W with an air variable capacitor. To reduce common mode current etc., what kind of ferrites would you reco

Just wanted to show off the completed unit. Thanks to all of you who gave input and support. The controller works great as long as I can keep RF out of the unit. Took a few days to overcome RF issues.

SOLVED (I think): Seems my voltage regulator was over heating, dropping the voltage to 3v. (It gets very hot.) I added a small heatsink and the voltage has yet to dip. I'll order a more robust heatsin

Group, I have purchased a Teensy 2.0 question is however is this the right hardware version? It seems compatible with the pin layout on the pcb but now it comes down to downloading the right software

I've build a controller for a loop covering 40-17m and a small air-spaced capacitor. A 36:1 gearbox with spring loaded gears provides a nearly backlash free coupling to the 200 steps/rev stepper. The

Hi, Simple question about firmware / hardware compatibility. I am resurrecting an older Loftur controller with the 4975 chips to operate an MFJ loop converted to a stepper. The firmware is version 4.0

I had originally proposed this idea in another useless thread so decided to start this thread to gauge interest. As currently coded, the magloop controller doesn't play well with some of my rigs which

Hello All. I built the controller PCB, probably about 2016, it’s marked r2, 2015-01. I completed it and checked the basic functions but never actually connected it to a loop. For one reason or another

Hello, I have building the MLA controller and I hurting against an issue> I am using firmware 4.10. Normally ( I think so) when going in Auto Tune a command has to be given to the FT817 via the serial

If anybody is interested in using Loftur's excellent loop tuner to automatically control the varactor tuning voltage on Rick Karlquist's (N6RK) also excellent tunable shielded loop antenna, it is easy

Hi, I am trying to compile the ML_v410 code but getting an error message, can anyone help please: Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "Arduino Uno" ML_v410:61:10: fatal error

quite obvious that teensy 3.2 is a major issue! for what I can ready here! I saw Teensy LC and Teensy 4.0, LC looks like totally different hardware format, what about 4.0 can it be used to replace dir

Hello All, I have a Yaesu FT-891 and wanted to get it working with Loftur's Magnetic Loop Controller, and I need to thank Jonasson Loftur VE2AO, and Joe Street VE3VXO for all your help. Joe recommende

Just wondering if it is absolutely necessary to insulate the VVC shaft from the stepper motor shaft?
