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

I built the controller without the optional SWR metering. I'm wondering if it wouldn't be possible to modify the code to display the SWR and power output from CAT on the radios that support it. Has an

Has anyone tried swapping out the dc motor for a stepper and running this with the tuner? There are already limit switches on the chassis so assuming the thing is geared down sufficiently I think this

Does anyone know if boards are still available? I've emailed lofturj@... twice but have not gotten a response. I did get one in September of 2021, but am looking for a second board. Perhaps he has mov

Hi All, Running loop controler with Icom IC 705. Has someone experienced this problem ? no data transfer from serial port to radio when pressing the tune button (SW 5). Been looking for a solution wit

In case anyone is having trouble with the connection between the 7300 and the loop controller (1) Loftur's cable diagram is correct - the jack socket on the 7300 has no connections internally for the

I remember in the days of the google group someone explained how to use a rotary encoder as the limit switch for a VVC.. My setup will be using a 11.5 VVC that goes from 54 pf to 1015 pf it is driven

Hello Gang, I am trying to help a couple of hams using the VE2LJX/TF3LJ firmware and having a bug when using ICOM 705. You don't need a 705, just ANY ICOM radios will do fine. would like to do a TeamV

I'd like to have the antenna tuner monitor the frequency of the radio while at the same time have my computer monitor and control the radio. My question is can I tap the TX RX lines of the serial conn

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

How did you guys manage the stepper driver controller temp? I've noticed mine gets VERY hot when it's been turning for a while and while it may not turn the capacitor all the way very often I did just

Hi there. Just finished building my Loftur LoopController (using the new 2021 v12.02 PCB) plus the SWR Bridge v1.3 PCB. I wanted to test it on my new ICOM IC-705. Unfortunately, that didn't work out w

Hi all I have a friend that is trying to make his loop controler work with his ic-705 He use a BT to CI-V adaptor and he can tune the radio and the tuner will follow. But when he try to start a tune f

Hi Jack. I have a HL2.0 and a Flex3000 that would love to be able to work with my loop controller. Have you ever been able to do a bit more than just the frequency communication? (witch is a hell a lo

I would really like to start building this controller but I cannot find any source where I can buy a Teensy 3.1 or 3.2 and I understand the code is not written to be working with the 4.x Teensys. At l

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

I just finished putting the controller in the chassis and did some testing. It seems when I push the menu button it powers off. When I release the button it comes back on. My thought is a short, anyon

Guys My 3D printer mounts and home cut CNC butterfly plates. All can be shared on Tinkercad, and conversions for Fusion 360 if needed. Regards Barry

Hello Group, I need help with this controller ! I have build the controller with the DRV8825 and turn with a 128 ppr optical encoder from Oak-Grigsby-Rotary-Encoder. The board works as it should, but
