In October 2018 I started using a Comtech 23cm transmitter for my ATV operations. Rather than use the 8-way dip switches to tune the transmitter, I decided to work on a project to develop a rotary LCD tuner using an Arduino Uno as the micro-controller. This article shows how I did it, including the code.
For 23cm Amateur TeleVision (ATV) I am using a Comtech 23cm transmitter powered by a 13.8V power supply.
This article tells why and how I replaced the voltage regulator.
On 19th January 2017, I started the process of making a printed circuit board for my 23cm amplifier project. I was extremely pleased with the results so thought I would write an article and make a video that shows how I did it.
In March 2018 I designed and built a multi-sensor, real-time temperature monitoring and logging system using Arduino.

In February 2018 I purchased a second hand Tennamast 10m tilt over Adapt-A-Mast complete with rotator cage, CDE Ham II rotator and CDE rotator controller.
Although I saw the rotator working I decided to check over the internals of the rotator, give it a bit of a service, refurbish the exterior and clean up the connection points.

Rawlplug is my new best friend! I will be using this to secure threaded studs in brickwork as part of my Tennamast installation.
In April 2017 I constructed a masthead pre-amplifier unit for 23cm ATV (Amateur Television) using a G8FEK low noise amplifier (LNA), two Tohtsu CX-520D coaxial relays and a homebrew PCB.
New wall brackets for supporting a pole and my new Yaesu G-450 rotator, WIMO SHF-2344 yagi for 23cm, EAntenna EA270ZB13 yagi for 2m and 70cm and masthead pre-amplifier unit for 23cm
Recently my Dad made me some custom wall brackets. I will be using the brackets to support a pole and my new Yaesu G-450 rotator, WIMO SHF-2344 yagi for 23cm, EAntenna EA270ZB13 yagi for 2m and 70cm and masthead pre-amplifier unit for 23cm.
