What have the Romans ever done for us?

by Chris G7DDN

Ah! The immortal line from Monty Python!

Well among many innovations, one that the Romans did do for us was to redefine our road system.

A revolution in road design

Goodness knows what roads were like before the Romans brought their new technology to bear, but it seems they may well not have even been very straight!

The Romans understood however that the quickest way from A to B was in a straight line; that is why the remains of their roads criss-cross Europe, whether or not there were hills in the way, so it seems.

He’s finally flipped!

Now what on earth is G7DDN going on about now? Has he finally lost his marbles? Well maybe you think I already have(!), but surprise, I see a parallel here with Network Radios.

Let me explain…

The Issue of Competition

When Amateur Radio was in its full pomp, the “competition” such as it was, was unimportant and even irrelevant.

Phone calls to foreign countries were inordinately expensive; Ham Radio was worth getting into if only from a financial point of view, but you also had the thrill of sending signals worldwide…

CB radio was, in the UK at least, first illegal, and then, once legal, limited to 11m FM and 4 watts output – hardly anything to be concerned about when the next door 10m Ham Band could transmit 400 watts of SSB or CW.

446MHz licence free radio at 500mW was no match for 70cms with 400 watts power and repeaters and satellites.

This is one reason Hams did not take their callsigns and procedures onto 11m and 446MHz for example. It did not make sense to do so.

The Path of Least Resistance

People naturally took the “path of least resistance” – a little like electrons!

The problem in 2018 is that there is “competition” for the hobby and it’s big gun competition!

The internet allows anyone, at no cost, to colour video call worldwide.

You can imagine your 14 year old child or grandchild doing this, while you might be sitting in your shack, grumbling about the lack of conditions on 20m or lack of activity on 144MHz.

Is it any wonder ordinary people don’t “get” Ham Radio in 2018?

What they do, like all of us, follow the easiest path to get the job done.

It grows and grows…

Now the growth of the Network Radios movement worldwide is astonishing, but on one level unsurprising.

It is, finally, with Network Radios, fairly painless to make contacts across the world, whatever the state of the Ionosphere.

After all if you are using the Internet as propagation instead, you don’t have to worry about things like the K-Index or the state of the sunspot cycle. (Fun though that is in its own right!)

And I am not decrying “traditional” Ham Radio by the way; I still use it regularly.

What I am saying is you cannot blame folk for travelling the “straight road”, the path of least resistance, if indeed what they want to do is communicate with like-minded radio enthusiasts.

It’s too easy!

After I gave a talk on Network Radios at a club recently, one gentleman remarked, “Well, this is all great, but the trouble is, it’s all too easy!”

True enough – but is that enough of a reason to dismiss it?

Sometimes, in any hobby, don’t we want things to be just a little easier?

Isn’t a 6 mile bike ride on your Dutch bike to see your friend on a Wednesday a nice change from that 80km sprint you do every Saturday on your racing bike with your local club?

The Convenience Factor

Sometimes, I like to chat with VK stations on Network Radios, rather than stay up all night trying to work them for a few moments on 80m.

Yes there is a thrill doing that that cannot be had with Network Radios, but there is also a satisfaction that comes with making radio friends in Australia with who I can regularly chat – and you don’t get that on 80m.

It is simply “horses for courses”.

‘Both and’, not ‘either or’…

No-one is suggesting that Network Radios will replace traditional Ham Radio – frankly it cannot do that.

But, you know, no-one I know is actually suggesting that.

Yes, it is new(-ish), yes it is different, yes it is convenient, and by gum, is it fun!

And, unless I am mistaken, people take up a hobby to have fun, above all.

And I cannot see anything wrong with that!

Hail Caesar!

What is PTT4U?

What if you could have a network of handheld and mobile radios with global coverage? Forget about expensive repeaters and licenses. Everything will work via the cellular 3G/4G network.

Either you want 1-to-1 or 1-to-many radio communications, this is for you.

No range registrictions. If you have cellphone coverage, you are connected! This means that each radio can be in different countries, and you are still in touch with your co-workers.

What distance do PTT4U radios cover?

There is no limit. As far as you have GSM/3G/4G or WiFi(Android models) signal you will be in reach. This means that you are only dependent on the cellphone carrier service, or a WiFi hotspot.

Why is this better compared to traditional walkie talkies?
Traditional two way radio will always be limited by distance and interference. As we work with a digital connection that relies on cellphones carriers, you will always experience loud and clear interference-free communications. Besides, you don’t need to invest in expensive radio infra-structures, like repeaters, towers, antennas or leasing sites.

Who can benefit from PTT4U?
Taxi & general transportation companies, law enforcement, private security guards, construction sites, logistics, box movers, agriculture industry, and anyone else how needs 2-way professional radio communications without range restrictions.

I need to cover a wide area and in multiple locations. Do I need a set of repeaters and antennas?
No. Our service uses the network of the GSM/3G/4G carriers. You don’t need to invest on any network infra-structure, besides the mobile or hand-held radios.

Does it work on any country?
As far as you have internet access (via 3G/4G or WiFi) then you can use our system, regardless the location.

Can the users talk between them, if they are in different countries?
Yes. Any user can talk to any other user, regardless the location.

Can I use my PTT4U radio as a normal telephone?
All our android based radios can make and receive phone calls and SMS/texts. The non-android based models can not be used as phones.

Can I use any SIM card?
Yes, you may use any GSM SIM Card. All our radios are SIM unlocked and compatible with any GSM/3G/4G/LTE Network.

Do you supply the PTT4U radios with a SIM card?
No. You should insert your own SIM card.

What comes with each radio?
Every radio package includes the radio, a charger, battery, antenna, belt clip and usb cable. The mobile radio still brings a mounting bracket, microphone and an external GPS antenna.

Do PTT4U android radios require a SIM card for WiFi strict usage?
No. If you just want to use a WiFi signal, then a SIM card is not required.

Can I use my own android smartphone with this service?
Yes. You just need to install our PTT4U application on your smartphone.

Can I use PTT4U radios with CDMA carriers, like Verizon in the US? 
No. All our radios require a GSM-based carrier. Our 4G/LTE radios can not be used with Verizon, because they require pre-approval of each device on their network.

Can I use the PTT4U radios with AT&T or T-Mobile, in the US?
In the US, our radios will work fine with AT&T and T-Mobile. In Europe, Australia and Africa will also work without issues.

Can I use PTT4U radios when I am off-grid, at sea for example?
You need an internet connection to use our radios. You may use a satellite hotspot like this one that will give you global coverage, even off-shore.

What happens if I don’t have internet?
If you can’t get 3G or WiFi then sadly it will not be able to connect to our network. However, you still might be able to use it as a normal phone if you get enough GSM 2G signal.

What is the function of the SOS button on the radios?
The SOS button will send an alarm to all users, showing the location of the user who pressed the SOS button.

How much data do PTT4U radios require in a month?
For a regular use, 500 MB data plan will be enough. In extreme conditions, where communications take place for long periods, 1 GB data plan may be required

Do you offer a dispatch system?
Yes, you can install our dispatch system on any Windows PC and contact any users, check their position on the map, speed, send personal messages, make private and groups calls.

Can I check the GPS location of the users?
Yes, you can check realtime location of all users and check their tracking too.

Can you define talk rights, and profiles permissions for each user?
Yes, all those details can be set.

Can PTT4U radios make private and groups calls to other users?
Yes, you can make both type of calls.

Can PTT4U radios send private messages to other users?
Yes, you can send private messages to any user.

Do I have to subscribe to any service to use PTT4U?
Besides having a data plan with your cellphone carrier, you need to subscribe our PTT4U yearly subscription.

How much do I pay for the PTT4U subscription?
Our yearly subscription price per radio can be checked here.

Why not just use a phone to talk to each other?
Our state-of-the-art network is almost instant, less than 1 second to the point of pressing the PTT on one radio to your voice coming out the other one or ones, plus you can talk up to 10000 at the same time, ideal for communications to field workers or patrol staff.

What happens if the server is offline?
That is very unlikely. We have 21 back-up servers, strategically located, hosted by state-of-the-art IDC (Internet Data Centres) in the North & Central America, Brazil, England, Germany, Hong Kong, Australia, Singapore, and other locations. In case of service degradation, you can count on our highly qualified IT Team expertise plus a decade of experience in the PTT over Cellular (POC) industry.

How can I pay the radios?
You may pay with Paypal or any credit card.

How can I pay the subscription?
You may pay with Paypal or any credit card.

Can I pay the radios and the subscription together?
Yes, using Paypal. We will provide you a recurring bill, where the first charge is the cost of the radio plus the first year subscription fee. You will see this detailed as “signup fee” on each product description. (the radio is included)

Do you offer other payment methods?
Not at the moment.

Can I become your reseller?
Yes, we are looking for resellers worldwide. Please contact us. You can check our list of resellers here.

I need a large amount of radios. Can I try before I buy?
Not at the moment. But you can buy one of our Startup Packages at a discounted price, before you invest in a large quantity of radios/subscriptions.

Can I get a free trial?
We don’t offer such program at the moment. We are very confident that you will love our system anyway.

I need 10 subscriptions or more. Can I get a discount?
Yes, see our discounts here.

If I order today, will I be billed today? And when does the subscription start?
You will be billed in the moment you complete your order. The 1 year subscription will start counting only when you receive the radios and ask us to activate the subscription. Like this, in case you fail the next recurring payment, you still have some time to re-active the subscription, without loosing PTT service.

Can I get a monthly subscription?
No. At the moment, we only offer yearly subscriptions.

Do you offer API access so I can use my own software to check user locations?
Yes, you can have access to an API to use your own geolocation solutions.

Do you offer full-duplex communications?
All our android radios allow regular phone calls, in full duplex. When using radio-like communication with the PTT4U, all communications will be simplex.

Do your radios have dual SIM?
Most of our radios offer dual SIM slot. Check the specs of each radio.

Do you encrypt the communications?
Yes, all communications are encrypted by a proprietary protocol and only the network admin of your organisation has access to the historical data.

I have a large organisation. Can I manage the platform myself?
Yes, you can manage all users, groups, talk rights, etc, accordingly to your own needs.

Is this for me?

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.

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.

My favourite Network Radios from 2017

I tried many network radios. So far, the Inrico TM-7 and the Talkpod N58 are my top choices! I have a feeling that in 2018, network radios will be the big hype of amateur radio! And you, which one is your favourite?

The Inrico TM-7 wins for its innovative mobile concept. A simple almost-obvious concept that is a hell of an idea! Robust and well designed. I must congratulate Inrico for their inspiration!

The Talkpod N58 was released in the last days of the year and I am already 100% convinced. First, it has a modern design. Second, the audio quality makes some Yaesu or Icom almost feel embarrassed. I doubt if a Motorola will sound better than this Talkpod. Bear in mind that these radios are targeting the professional market. The details, the design, everything has been built with impressive detail and high quality materials. It’s not the cheapest radio out there, but it is worth every single cent!

I am really excited with this new concept and, from me, you can always expect my passion on this job and my commitment and best efforts to give you an outstanding support. Thanks for all your trust along this amazing year!

I wish you a Happy New Year fulfilled with health, love and some money – to buy some radios 🙂
