Like last time, there are two parallel threads about this on this Forum alone. https://www.vklogger.com/viewtopic.php?f=31&t=14088 This only fragments discussion and hinders effective coordination. A bit like the the endless splinter groups on social media. https://i.pinimg.com/564x/10/1b/21/101...

Found this elsewhere, and is too good not to share more widely. Terry Gaff Aug 12 #13225 Hey all, After a few mins tracking some sats, via my K3NG controller (not the issue BTW), or manually, the elevation will not go down... but it will however rotate upwards. Up to this point, after I wait for may...

Following on from the previous bug report, one issue, easily overlooked by those not entirely familiar with the Nextion display, has been identified that can easily cause grief, Along with creating fonts with iso-8859-1 encoding, make sure when setting up your Nextion HMI project in the Nextion Edit...

Thank you for your interest. I get email queries about this every week. I'm sorry, but experience has taught me not maintain a waiting list for anything! It becomes extra work maintaining that, contacting others, and with too little time available. I did maintain a list for the IC-910 MultiSend kit ...

This video shows how you can get the degrees symbol ° on the K3NG Rotator Controller's Nextion touchscreen.

It's a simple matter of editing four lines of code in the main .ino file.

Get you Arduino programming leads out!

It appears Icom (Australia) aren't running adequate virus protection!

Yes, definitely broken somewhere.
Come back tomorrow.

Hi all The K3NG Rotator Controller project is aimed towards Arduino Mega 2560 or similar hardware. Standard ADC resolution on many of the Arduino boards is 10-bit, however the Arduino Due, Zero, and MKR family and Teensy 3.x family have 12-bit ADCs. So if you’re running this hardware (I'm using a Te...

Alan, W2AEW, continues his series on using VNAs, and specifically the NanoVNA. Why a VNA needs to be calibrated | how to calibrate a nanoVNA This video describes why a "user" calibration is needed when using a VNA (vector network analyzer), what systematic errors it corrects for, what is m...

A Yaesu G-800DXA rotator is being used for azimuth satellite tracking being driven from SatPC32 via a K3NG rotator controller interface. https://vk4ghz.com/wordpress/wp-content/uploads/DSC7335_800.jpg The factory fitted trimpot is only a standard single-turn trimmer, which was awkward to set to a pr...

K3NG Rotator Controller for satellite operations. Anthony, K3NG, has done a fantastic job with his Arduino rotator controller project.
