Setting up a cellphone to access live RF gateways across the world can be easily done.
Using a PTT-enabled phone will make it even more radio-like operation. And before the discussion starts, let me make a disclaimer. I am am ham radio operator (CT1EIZ) since I was 16 years old (I’m 42 now) so I tried most of the modes available like HF, VHF and UHF (FM and SSB), SSTV, ATV, Satellite, Packet, APRS, Pactor. I had large antenna towers, with rotators and all. But I also like Echolink, D-STAR and anything that is new. In my opinion, CW is nice but we shouldn’t stick to it and is not a shame to hamradio via a cellphone. Anyways, at this stage of my life, I am not able to install an antenna on the roof top. I have some gear on my sailboat, but during the average day I am happy by using my Radio-Tone RT3 PTT phone with IRN running on it via a 3G connection. Signal is always available and audio quality depends on the other hams coverage. The other hams can be using the same setup, or their regular radio stations.
Having said that, let’s learn on how to start accessing the IRN network.
1. You need to download “Team Speak 3”. It’s available for Android, iOS, Windows and Mac.
2. You need to add the IRN Server. Details are as follows:
Label: IRN CrossLink Server (or anything else you want)
Password: leave it empty
Nickname: CALLSIGN – Your Name (ex: MYCALL – John)
And you are done!
Once connected, you will see lot’s of available channels. After you have proven that you have a valid license, you will be able to TX, Before that, only reception is possible. Remember that besides the fact you are talking over a phone, your voice is being transmitted off the air via RF, so act as if you were using a repeater – identify yourself with your callsign, etc.
