Network radios

A network radio has been owned for several years - 5 to be precise! Mine looks just like a 2m or 70cm handheld complete with PTT and antenna. It has been used on Echolink, and on DMR with an app called Droidstar.

The phone is essentially an Android smartphone, so it can run all sorts of apps too.

I'll be honest, I prefer "real" radio where the link is open to the variations of the ionosphere or troposphere. I can see they have their place where conventional RF radio is not possible such as in hotels or care homes, or where external antennas cannot be erected. At the depths of solar mimima, I can see them having a place too.

DMR and network radios

Many people have no DMR radios, but have Android phones. This was the case with me. I had a network radio that was hardly used.  I found an app called Droidstar that enabled me to access the DMR network and thus worldwide contacts with a handheld. It has not been used often, but at least I can use DMR if I want to. I have found it more interesting just to listen.

What is working DX?

"Each to their own", as they say. These days, the boundaries are blurred and it is a long time since working DX meant HF bands and QSB. An example is DMR which allows users to talk with others around the world on their VHF handhelds.

In the depths of the last sunspot minimum, many of us bought network radios that used the internet as the backbone. Mine looked and behaved just like a VHF handheld complete with antenna and PTT. With it, one could connect with repeaters on the far side of the planet.

I never enjoyed mine and prefer to work stations the "old" way. Now the sunspot numbers are climbing, this is more possible again.

Now, I am not saying one is any better than the other.  As they say, "each to their own". Ours is a hobby of self training. I am sure there is as much to learn from DMR and network radios as from working DX the "old" way!

Echolink

It is a while since I have tried Echolink. With Echolink on your phone or PC, you can access repeaters on the other side of the planet, often used by locals to talk to others on VHF or UHF handhelds. You can even buy network radios that use the internet as the main bearer. 

I have an Android handheld with PTT that looks and feels just like a VHF handheld. I have to admit it is not used often as I prefer experimenting with "real" radio! 

If you cannot have big antennas or amateur radio in the conventional way, this may be a way to keep in touch.

Network radios

It is becoming an increasing issue that some amateurs can no longer enjoy their hobby as they are not allowed external antennas or because their noise floor is too high. 

For some, the answer may be network radios. These use the internet as the main propagation mechanism rather than the ionosphere. All that is needed is a wifi or mobile connection such as 3G or 4G. 

With these, and systems like Echolink, distant repeaters can be contacted and, via these, handhelds on the far side of the planet. They are often mobile phones with a PTT and antenna, looking much like a VHF handheld.

I find these somehow dissatisfying.  Maybe in 10 years time I shall think differently.  At the moment I get more fun from experimenting with "conventional" radio. I know amateur radio is changing and we should embrace all forms of communications such as DMR and network radio.

Network radios

One of my Facebook memories today was about network radios. These look like VHF handhelds or mobiles with PTT and antennas. 

They use the Internet as a backbone and are basically Android phones. These are available from several dealers. I suspect dealers see the future with fewer radios sold, many of us getting older and frailer, more of us in care homes and unable to access conventional radio. 

They are ideal for Echolink and similar. I have one, but find it oddly unsatisfying. In 20 years? 

See MLS for typical examples.

Network radios

A few years ago, I bought a network radio. This looks like a 2m handheld but uses the internet to connect to distant stations using systems like Echolink. It works over WiFi or mobile phone networks. 

Since I bought it, I hardly use it. For me, network radios are just not satisfying. It has a PTT and is very similar to a VHF or UHF handheld. One of the fun things is working stations via distant repeaters e.g. in the USA or Australia.

Personally, I prefer "real" radio, although for some these are a good substitute.

Network radios and Oscar 100

I suspect many who get network radios or use Oscar 100 are/were concerned about poor conditions and are/were looking for a reliable means of chatting with people a long way away.

Certainly my own network radio has hardly been used. I bought it 2 years ago when we were on the way towards sunspot minimum. At least with Echolink I could access repeaters on the other side of the planet. Likewise Oscar 100 should open up DX to a good proportion of the planet at any time without fading. In many ways you might consider Oscar 100 perfect. Once the gear is set up and the dish(es) aligned there is nothing else to do. No neighbours to annoy, no big towers or beams to worry about....and yet.

Yet, for me at least, neither satisfies. I prefer "real" radio where every contact is a challenge. After about 60 years in the hobby I have found that the changing nature of propagation is what gives me a buzz.

Different people enjoy our hobby in different ways and the world would be a sad place if we were all the same.

Maybe my network radio will get used.

Network radios

About 2 years ago I bought a network radio. We were entering a time with low solar activity and this, at the time, seemed a good idea.

The handheld has hardly been used. I prefer "real radio". Echolink contacts are strangely unsatisfying to me.

In these odd days other people may think differently.

Basically these are Android phones with an antenna and PTT. They use the internet but feel just like a VHF handheld. In many ways you would think they would be more popular.

Network radios

At the moment we are at sunspot minimum and conditions on the higher HF bands are poor. If you look, there is still some DX there, but it is much harder to find than a few years ago.

Conditions will soon start to improve, but in the meantime some will turn to network radios. These look like typical 2m or 70cm rigs, but use the internet to connect.  They can be useful to connect to distant repeaters via Echolink.

Portable network radios have antennas, PTTs and batteries and look and feel like conventional radios. Although I have owned a network radio for over a year, it hardly ever get used. They may appeal to some.

PTT Androids

It seems the big retailers are pushing network radios hard.

See www.hamradio.co.uk

MLS are selling a couple of new Android PTT radios as the next best thing since sliced bread. Maybe they look at the amateur radio demographics and think many of us "oldies" will end up in care homes and will need network radios to keep in touch? They can see an end to their traditional businesses unless they adapt? As I have said many times before, in 20 years time, our hobby is likely to be very different.

Network radios have certain advantages. As well as access to many repeaters by apps such as Echolink, they also support other services link Zello and the usual apps like Skype and emails. Agreed, this is not amateur radio as we knew it, but it serves a purpose. Personally, I still prefer experimentation at the frontiers, but I also see some benefits from network radios.

Network radios away from home

When away from home is a classic case when network radios are useful, especially with a low cost data SIM. Not only does it allow access to things like Echolink, but also access to emails and the internet.

More network radio

Up to now I have just used my Inrico T320 network radio on Wi-Fi. Somewhere I have a Virgin "pay as you go" SIM with some credit, I think. Maybe I should put this in. If I remember correctly this lasts until the credit expires, which could be some while in my case! I need to check what Virgin charge for data on "pay as you go".

Excellent Moonraker service

Well, I succumbed and decided to buy an Inrico T320 network radio from Moonraker. The first unit had faulty software loaded. Without quibble, Moonraker despatched a replacement unit and collected the first unit. I cannot fault their customer care and I am very inclined to use them again. Well done!

Some are very sniffy about network radios saying this is not real amateur radio.  They use the internet (via wifi, 3G or 4G to connect with Echolink or similar services). Basically they are Android phones with a PTT in the style of a 2m or 70cm handheld. The beauty is they have full Android functionality as well (like BBC News, GPS, camera and email). This is not the same as traditional amateur radio, but I have already had great fun with mine. My first QSO was via GB3SD near Weymouth, Dorset.

I still prefer "traditional" amateur radio, but these have a definite place. One thing is very apparent: repeaters the world over have fewer stations using them. I am still exploring.

PTT over cellular radio - NOT amateur radio

With 446 radios at ridiculously low prices and PTT over cellular radios available, I am wondering how "traditional" private mobile radio companies survive. On the face of it, PTT over cellular (i.e. network radio) offers international coverage or very local coverage.  For example, lorries could be tracked internationally, and drivers contacted as if they were in the next village.

446 or similar radios offer basic communications well suited to pop-up events or occasional use.

Between the 2, most PMR use is covered at sensible prices. PTT over cellular often has GPS, photos and big data capacity too.

Network radios abroad

I guess a network radio would be useful on holiday as long as you have a roaming SIM or wifi access.

Network radios

Both PW and RadCom have articles in recent editions on network radios.

These look like conventional mobiles or portables with a PTT and an antenna (in the case of portables) but they connect to the internet, usually as the units are Android devices. They link to apps like Zello and Echolink, so can link to repeaters and amateurs elsewhere on the planet e.g. a mobile in Australia.

In reality they feel like conventional radios on 2m or 70cms. They can use 3G or 4G cellular networks or wifi. Apparently data only SIMs are very low cost. Not having used one I cannot comment.

With worsening HF conditions, these may appeal to many. Using the internet means that QSB and local noise are not problems and big antennas are not needed. Purist will ask, "is this real amateur radio?".
