Do you have antenna restrictions?

So, you are an amateur radio enthusiast. You just moved in into a new apartment and came to the conclusion that your neighbours won’t let you install an antenna on the roof.

Well, that’s ok. You are still excited with the new home, so you decide to just stick to your old FM handheld. You go close to the window and start trying to hit all the repeaters in the area. You don’t hit a single one. Already desperate, you stick your arm outside the window, set the HT to full power, and still, nothing. You can hardly hear a transmission.

Don’t dispare. You are not alone. This has happened to many other hams across the world. If you really like hamradio for the essence of having QSO’s with other hams and discuss about technology, you can still use the IRN – The International Radio Network.

This system is connected to several hamradio RF channels across the world and you can stay in touch with the community. All you need is WiFi connection, or a 3G/4G data plan and you are connected. Note that you need a valid hamradio license if you want to transmit on IRN.
It’s fun. It’s still hamradio! (unless you think that hamradio is only CW – Don’t let others tell you what is and what is not hamradio. Think for your self. Enjoy the hobby! We are not in the 60’s anymore)

Hamradio is what you want it to be!

Hamradio on a train

We all love talking to the hamradio comunity, right? What if you could keep in touch with other hams, when travelling with your handheld and without access to a local repeater?
Imagine a cross country, long train ride full of nice and relaxing QSO’s.
The other day, RedBull Air Race came to Oporto, Portugal. As I live in Lisbon, I decided to take the 300 kms ride by train to watch the race. I took my handheld network radio with me. It looks just like a conventional handheld transceiver. But it’s not. It is a cellphone with a PTT button. With TeamSpeak 3 installed and tuned into the IRN – International Radio Network, I was connected to my favourite hamradio Talk Group: The Guild QSO channel. I tell you… What a fantastic ride. Well, I must admit, I love a nice cross-country train ride. I just sat back, relaxed and enjoyed the views through my window, while talking to my ham friends. Luckly, this train offered free Wi-Fi connection, but I could also have used my 3G dataplan.
I know this is far from conventionl hamradio, but things are evolving. If for you this is not hamradio, because you are using a commercial network for voice transport, I respect you, but… The way I see it? A hamradio OM, on a relaxing train ride, with a cute radio-like handheld, talking to other hams, on the other side of the ocean. For me, this is nothing but “hamradioing“.
Enjoy your ride!

IRN – International Radio Network

What is the IRN?

The IRN (International Radio Network) is a VoIP/RoIP system using Teamspeak 3 (TS3) that allows radio users to TX/RX using RF around the World using  different devices (Mobile Phones, Tablets, Computers etc) for free.

The system also allows users to create private talkgroups for point to point or private group QSO’s.
If you would like to add your link, repeater or hub to the IRN system, please use the contact us section to drop us a line.
TS3 is available on Apple, Android, PC, Mac and Linux. The IRN has it’s own private server allowing hundreds of connections at once. There are different talkgroups (channels) within that allow users full RX/TX capabilities across different radio networks and systems from across the globe.
To make it more interesting, you can use PTT-enabled smartphones like the ones listed below. Most of the hams use PTT-enabled phones, so they can use the IRN with the same style as they use a handheld radio. The IRN talk groups can be accessed via GPRS / 3G / 4G / Wifi or RF (depending on the repeaters).

Is this still hamradio? Read this article.

Please note: This system is free to use for both non-licensed* & licensed hams. Live ham-radio repeaters can only be accessed by licensed hams.

*Non-licensed users must apply for membership of IRN in order to have a callsign generated for them (Don’t worry, it’s also free).

The following devices have a dedicated PTT button that will make your experience even better when using the IRN.

Zello in Germany – a great community

On the Kanal Zello Funk we are a great radio community.

Here, hobby radio operators, former and active radio amateurs, managers, housewives, taxi drivers and truck drivers, security and students meet. Everyone can join and be welcome on the canal.

The free app zello works on any PC, Android, BlackBerry or IOS.

Zello converts the mobile phone into a walkie-talkie. That is, the voice messages are reproduced directly in real-time at the call partners. All you have to do is press the push-to-talk button and you will be heard by the friends.

At Zellofunk, we talk about everyday things and have fun with each other. We are joking, laughing and enjoying the opportunity to reach zello radio friends all over the world. We also talk about serious issues and above all we help each other when necessary.

Zello while driving

Zello radio in the car

In order to facilitate cell use during driving and to make it safer, a Bluetooth PTT button can be used when using a mobile phone.

In the illustrated example, a Samsung Galaxy S7 was used with a “Auto Bluetooth Media Button” from XCSource.
Both devices can be easily coupled and work flawlessly.
The play / pause key has been defined as a send key and operates (depending on the setting) in PTT as well as in toggle mode.
Also, the volume buttons are in function and allow the adjustment of the mobile volume.

The included accessories allow direct attachment (by clip) to the steering wheel. The hand does not have to leave the steering wheel while pressing the PTT button.

Alternatively, the Mediabutton can also be glued at a suitable location (using adhesive tape supplied).

After the first tests, the combination of mobile phone with Mediabutton and integration into the vehicle media center (to increase the receiver volume) is a useful solution for mobile cell operation!
