Offset satellite dish for QO-100 Es’hail-2 project

April 4, 2020 No Comments

In February 2020 my 1.5 metre prime satellite dish was destroyed by strong winds from storm Dennis. The dish was ripped from it’s mount overnight and I found it at the end of my garden bent and dented. Beyond repair I had no choice but to scrap it.

After a few weeks of searching I purchased a secondhand 1.5 metre x 1.7 metre offset dish.

This blog post contains pictures of the dish as it arrived. Soon I will be making modifications as part of my QO-100 Es’hail-2 project.

MiniTiouner V2 Construction Project

March 22, 2020 6 Comments

MiniTiouner hardware was designed by Jean-Pierre F6DZP and is a DVB-S/S2 USB receiver that works with MiniTioune software. It covers 143MHz to 2450MHz and was designed for use by Amateur Television (ATV) operators.

Like other amateur radio operators I want to use the MiniTiouner and software to receive transmissions from the Es’hail 2 QO-100 geostationary satellite.

I built my MiniTiouner (phase 1) in January 2019 but due to work commitments have just got round to using it.

Comtech 23cm Amateur Television (ATV) rotary LCD tuner using Arduino

November 30, 2018 2 Comments

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.

Checking feasibility of receiving and transmitting Amateur Television (ATV) between M0NWK QTH and Lincoln Cathedral repeater GB3VL

When I was thirteen years old, I remember hooking up an old Amstrad analogue satellite receiver to a homebrew yagi antenna to receive amateur radio television (ATV) from Lincoln repeater GB3VL. That was as far as I got with ATV until a recently.
