What does a Hot Spot do and why do I need one?

 Reasons why you might consider buying or building a Hotspot

My MMDVM hotspot runing Pi-Star

The control panel

  • Enables reception in areas of the house and around it that may be poor reception otherwise.
  • Many people live in flats or cannot mount antenna due to housing or local council regulations, this provides them with a link, via the internet to multiple digital voice systems and talk groups.
  • Allows easy access to additional talk groups. Some repeaters may provide access to talk groups, possibly on a schedule. This is great but also can be limiting if your local repeater is dedicated to TG91 worldwide and you wish to use TG2350 UK. Having your own node allows you to be in control on-demand.


  • Allows Multimode operation from different radios. You can have a single node and select from DMR, C4FM/Fusion, YSF, P25, NXDN, POCSAG. The node is generally capable of switching automatically once a transmission has ceased for a selected time period
  • Allows mobile operation - You can set your mobile phone up as a mobile hotspot and link to the node from anywhere with mobile phone reception. This is also useful for operating, say from a work location without directly connecting to the internet at work.
  • You can talk to other Digital Modes operators, you will soon discover that every mode has it fans and because we are communicating via the internet the system becomes mode-agnostic. That is you can talk to Fusion (or anythign else) from DMR for example.

I have heard people say 'It's not proper radio', well it allows people to communicate and radio is generally involved at at least one end of the transmission, so I say the advantages outweight any prejudice if it allows more people to do radion!

Getting started with the Anytone AT-D878UVII Super, making a codeplug

I passed my Foundation Amateur Radio Exam and have been using the Baofeng UV-S9 for over a couple of months (the first month just listening). I decided it was time for a better radio as a lot of activity seems to be on digital channels and links like Echolink, All Star etc. and the Baofeng scan facility is limited to either all channels, or all frequencies in one waveband. So I pre-ordered the Anytone AT-D878UVII Super as this is the only budget radio that seems to have enough memory to download the entire DMR contact list which now exceed 200,000 registred users.  My new Anytone AT-D878UVII Super The Anytone can hold upto 500,000 so it should be good for a few years. When programming a radio like this people refer to a codeplug, it is not a physical plug, rather it is data that is specific to your radio's frequencies, repeater channels, DMR contacts and personal settings. It will also contain your DMR Id so beware of exporting the data plug to other people without first removing

The Trident multi Band aerial for scanners and sdr reception and transmitting

I wanted a Discone type aerial, they look great! Then I read some reviews and people said that a dual band dipole worked better. I also wanted to be able to use it for different bands. So on YouTube I found the best dual band aerial design I could. Then I found this 2M ground plane aerial/antenna . why not combine elements of both? So why would this work? Well, when an antenna or aerial is resonant it's impedance falls to around 50 Ohms. When it is outside resonance the impedance rises to several thousand Ohms and becomes irrelavent as it reduces the signal. So when you are on 2M the other tripod elements are ignored and you can achive good power transfer and gain. The same is true for each other band. I have seen this on other aerial designs too. It does work I promise you! Antenna vs aerial, what is the difference?  An aerial is to receive radio signals only, there are other design considerations but an Antenna has to cope with high voltages and heat. An antenna is designed to

Welcome to TekMaker

TekMaker is a channel designed to help people of all ages and abilities to learn about and build projects for Computers, Electronics and now Amateur Radio too. Having witnessed many poor quality and badly informed channels I decided I could do better. I previously worked in Electronics for 25+ years including design work and been involved in computer servicing, networking and programming for over 20 years. I hope to produce projects and videos and instructions that are simple enough for any age or ability. That said some projects are main voltage powered and should be built with extreme caution and supervision. You do this at your own risk! Rather than just making projects to use once and then put on the shelf I will endeavour to make projects that will connect or work together and for useful things if you want to set up an electronics or single board computer lab at home.
