This is a video hosted by the Leicester Radio Society on the MMDVM software created and written by Jonathan Naylor G4KLX

In this video I go through the Xiegu X5105 unboxing and first impressions for those looking for a QRP rig with many features.

Fitting an N type male connector to coaxial cable.

The effect of a 1:1 balun on a resonant dipole

Advanced Exam training video on potential divider question from an RSGB mock exam...

Working through answers for the RSGB Advanced Amateur Radio Licence mock test 2 tutorial.

Advanced mock question work-through q58 tutorial for amateur radio, mock 2.

This is a more detailed explanation of the FM modulator and how the varicap diode is used.

This video shows you how to install QSSTV on a GNU/Linux system which includes Raspberry Pi running Raspbian

In this video I show downloading, preparing and running Xastir on Raspbian Buster/Linux systems.

YAAC (Yet Another Aprs Client) is a very easy and clean APRS client that can be downloaded from the internet.

In this video I demonstrate how to connect a TNC to YAAC and use it for APRS, messaging and more!

Continuity testing coaxial cable after connectors are fitted.

Fitting heat shrink over coax cable connector n type or pl259

Fitting an N type connector

Fitting a PL259 UHF connector on RG213 coaxial cable

In this video I demonstrate how to connect a TNC to Xastir and use it for APRS, messaging and more!

In this video I am describing, demonstrating and setting CTCSS on amateur radio, in particular, on the Yaesu FT-8800 dual-band FM radio.

In this video I show how to set up a radio for crossband repeat. In this example I use a Yaesu FT-8800

In this video I show how to set a radio up to work "split".

In this video I demonstrate setting up a Yaesu FT-8800 radio to operate with a crossband split

Coaxial cable radiation when feeding a tuner with a balanced line without a balun

In this video we look at how to use Jitsi for video chats. This is an easy, free, no-registration programme that is simple, efiicient and feature-rich!

Here’s a video on how to calibrate an MMDVM (Multi Mode Digital Modem) using an RTL-SDR dongle and SDR Sharp as a spectrum analyser.

This video describes why a "user" calibration is needed when using a VNA (vector network analyzer), what systematic errors it corrects for, what is meant by a measurement plane or calibration plane, and finally an example of how the calibration is performed on a nanoVNA.

In this video, with some experiments, we shall see the meaning of "unbalanced" and "balanced" regarding transmission lines and their practical effects.

In this video I show how to install powerpole connectors to the positive and negative cables. These are great to fit on the wires of your battery or power supply and your radios so you can swap the radio quickly and easily. They are robust, reliable and they cannot be connected the wrong way around.

In today's video I demonstrate how to Install a Yaesu FT736R CW filter to improve selectivity and to cut down on the background noise to make listening more of a pleasure.

Hi guys, today we will show how to set up and use Radio Mobile. Radio Mobile is software that predicts radio frequency paths between two points or more on the Earth. It can also show RF coverage of an area. This can all be determined by inputting the type of antenna, its height above ground, the gain of the antenna, the power of the radio etc. Really useful software! Check it out...

YAAC igate - Setting up YAAC as an igate

This presentation talks through the etiquette for amateur radio particularly for contesting and getting involved in a contest. Robin covers this in really helpful detail to help less experienced amateur radio operators get their feet wet!

In this video I go through the Xiegu X5105 unboxing and first impressions for those looking for a QRP rig with many features.

In this video I measure the RX current on the Xiegu X5105 QRP radio.

In this video I go portable to Yorkshire and demonstrate how to programme memories into the Xiegu X5105.

In this video I demonstrate how the receiver sounds on the Xiegu X5105. I have tried adding the DSP and the noise reduction. I will do a separate video of the two features but on this initial trial, I have found them both very effective!

In this video I show that the graph that is used while operating the CW decode also does show SSB signals when listening to voice too.

In this video I demonstrate the CW decode ability. If you have an X5105 yourself and know how to get this working more consistently, please leave details in the comments below!

In this video I have recorded a QSO with members of my club in Nottingham using the Xiegu X5105 - I was camping near Ripon, Yorkshire and the signals were excellent - not bad for 5 Watts!
