How to install a SD card in Inrico TM-7 by N5MXI

1. Remove all external screws except the four on the bottom of the radio.

Remove the four bottom screws last. These free the bottom PC board the SD card slot is mounted on. Do not remove SIM screws.

2. Open the radio case as seen below showing bottom PC board and SD slot (red arrow).

3. Remove bottom PCB carefully so as not to damage attached wires and ribbon cable and lay on a flat surface with card slot facing up.

SD card slot cover is hinged. Slide cover in direction of the red arrow to unlock and open the cover.

4. Picture below shows SD card slot opened.

Place SD card onto slot with contacts facing down. Make sure side notch on the SD card matches up with notch of the card slot.

5. Close the cover making sure SD card remains in correct position.

Slide the SD card slot cover in the direction of the red arrow to lock in place.

6. Re-assemble case starting with the four screws holding the bottom PC board then all other remaining screws.

It’s all about Propagation by Chris G7DDN

While preparing a talk about Network Radios for my local club here in the UK, it struck me that the underlying issue about Network Radios and “traditional” Ham Radio is really one of propagation.

Let me explain.

Those of us who are hams or who have dabbled in Shortwave Radio for many years know the theory of long distance propagation. Radio waves reflect from the Ionosphere (or duct through the Troposphere in the case of VHF/UHF) and end up a long distance from their starting point. (There are other modes of propagation too, of course, but I’ll use these as a generalisation)

Natural v Man-made

The atmosphere is, of course, a natural phenomenon and we depend on it “behaving” in order to get our long distance contacts. For Network Radios, it is the Internet that is the propagating medium, at least at their end of the contact.

I can see certain similarities between the atmosphere and the Internet. The web is, in effect, a man-made propagating medium for signals – as opposed to a natural one.

Parallels in other hobbies

This got me thinking about parallels in other hobbies.

In rock climbing for example, enthusiasts climb on natural rock formations in the great outdoors – very scary – you won’t catch me doing that! But there are also many rock climbing “walls” indoors too and there are photos of these all over the web.

What strikes me from looking at these photos, is that the people climbing indoors seem to be having just as much fun as those climbing outdoors. The two experiences are different and yet peculiarly similar.

The outdoor rock (like the ionosphere) is natural – the indoor rock (like the Internet) is man-made. Neither stops the climbers having fun actually doing their climbing! Interestingly too, there seems to be a lot of youngsters doing the “man-made” climbing…

“Real” Ham Radio?

It is easy to dismiss the whole Network Radio phenomenon as “not real Ham Radio” but listening around, it seems there are plenty of folk enjoying radio (or radio-like experiences) without the “necessity” of transmitting on certain specific reserved bands.

As we go further into the 21st Century, I think we will see the lines between “naturally propagated” signals and “artificially propagated” signals blurring further.

As someone who enjoys CW, HF, VHF, UHF as well as D-STAR and Network Radios, I don’t see why that should be an issue, unless we as amateurs make it one.

Let’s keep what is great about the past of Ham Radio, without dismissing the newer technologies borne of the fantastic innovations that keep coming our way in the 21st Century.

Questions, questions, questions…

So, is the Internet any LESS valid as a mode of propagation for amateur signals, simply because it is man-made, rather than a force of nature?

Is all this a threat to Ham Radio as a hobby, or is it an opportunity?

Challenging questions and ones we can probably only answer for ourselves.

Perhaps the only question that matters is, are you enjoying your radio hobby, in whatever form it takes?

Download the the new Echolink version! It works great with Inrico TM-7. The PTT button functionality has been added and the screen UI has been adjusted to fit the specific requirements of the Inrico TM-7.

Tests have been performed with a Talkpod N58, Radio-Tone RT4, and obviously, with the TM-7. All network radios should work fine with this Echolink version, including the Sure F22+, F25, Inrico T298s and also the new Inrico T320.

If you want to run Echolink and Zello at the same time, please read this.

F22 in Summer & RT4 in Winter

If you have a valid hamradio license, you can transmit on the live repeaters around the world. What are you waiting for? Keep in touch with your ham community ANYWHERE on the globe! As far as you have internet connection, either by WiFi, 3G or 4G, using a network radio was never so easy to access a global network of amateur radio: The IRN – International Radio Network that combines DMR, Echolink, AllStar and analogue repeaters all together. This global network is growing at an incredible speed.

You will experience Crystal and loud sound, amazing looks, batteries that last for days. You can, for example, cross-country by, without ever loosing signal and worrying which repeater frequencies to use.

Picture below: Radio-Tone RT4 on a rainy day.

Not for amateurs

PTT4U is a state-of-the-art network radio service for professionals.

Relying on the GSM signal, our radios will be able to talk to each other without any range restriction. Each radio works with a SIM card (not included) and uses GSM/3G/4G and some modes even work with WiFi signal. This means you don’t need to spend a fortune on expensive radio infra-structures, repeaters, antennas or site rentals. All the network infra-structure is provided by the GSM carrier.

Private and group calls are available. Your team members can be in different countries and still within reach. Each user can check each other’s location (based on their profile), send messages and SOS alerts.

All you need to do, is to purchase our network radios, depending on your needs, insert your preferred carrier SIM card on the radios (a monthly data plan of 500MB will be enough) and subscribe the yearly PTT4U service. You will need one yearly $49 subscription for each radio. And that’s it! No more headaches.
