Talkie Walkie Review of the Binatone MR600 PMR 2 Way RadiosJust prior our 2003 Devon holiday we bought a twin pack
Private Mobile Radio (PMR) system, often called talkie walkies or 2
way radios. Here's our review...

Off we go then Although they're often referred to as 2 way radios, in fact many users can communicate provided all the units are set to the same channel and CTCSS code. Unlike a mobile phone, only one person can talk at once, ie one way at a time. |
The holiday cottage
was just up the road from the local convenience store and our first use
of the talkie walkies was when Belinda, armed with a radio, received a
call from Mike when he remembered a shopping item (and it wasn't the
beer!). Without the talkies he would have had to use the mobile
phone, or get off the sofa and run down the road - and we can't have
that! Another occasion occurred when Mike 'disappeared' on the
South Devon Railway train and
Belinda called him up to ask where her coffee was he'd trotted off to
get. It turned out he'd got the coffee, but then got delayed
yacking to some steam buffs in the dining car! >>>
<<< On a hot walk round the South West Coast Path from Hope Cove Belinda took a breather at Thurlestone while Mike carried on towards Bantham. Here we began to realise shortcomings with the transmission range, as shortly after rounding the headland contact became patchy. Sometime later back home we did some range tests...
Above. The talkie walkie signal faded out once round the headland on the other side of the beach seen above.
Testing the talkie walkies 3 km range
Safely back from holiday we decided to test the actual
distance we could communicate with the 2 way radios. We started
off at our home, Belinda walked towards the village centre (picture
right) while Mike walked in the opposite direction. It wasn't long
before reception got patchy and we lost touch. On our return home
we plotted the distance
achieved on the map
and it turned out to be barely 1 km, a third of the quoted range.
Now, although built-up we hardly live in the great metropolis so were
rather disappointed with this. But to balance this we also took
the talkie walkies up our local hill on the South Downs, and from the
top we could comfortably hear our local garden centre over 3 kms
away. They use professional PMR446 radios, but we also heard
domestic signals from a similar distance. A check on the Internet
revealed that not all consumer PMR talkie walkies are created equal and
some perform better than others, despite government specified design
limitations (power limit, no 'gain' aerial, etc).
Testing other features of the 2 way radios
The talkie walkies have a VOX feature that starts
transmitting once it detects your voice. Three levels of
sensitivity can be set and we tried this in the car using the provided
hands free ear/mic cable. Ambient noise caused transmission on
the most sensitive setting, while the two lower settings required
shouting to make it send. Best forget the VOX function
then! Then again, it could function well as a baby alarm - just
need the baby now.
There's a scanning feature on the talkie walkie radios that continually scans all eight channels for a signal, and the LCD display illuminates briefly when a button is pressed. The display indicates when transmission or reception is taking place, battery charge state, channel, CTCSS code and volume level.

We found a slight delay apparent when pressing the PTT and when using the CTCSS codes which resulted in missing the first few words of a message. But we quickly adapted to this by delaying speaking for a moment after hitting the PTT. Speech quality was 'loud and clear', except when talking close into the mic, then it sounded 'breathy'. A flimsy belt clip is provided, but we don't trust this so we purchased a couple of suitable soft carry cases which allows the talkie walkies to be carried over the shoulder. << The talkie walkie fits comfortably in the hand with the required controls falling readily to, er, hand. |
Using
a CTCSS code isn't compulsory, in which case you may hear other users
on the same channel. However, using this code doesn't ensure
communication privacy and can cause reception to cut-out if a stronger
transmission is in operation on the same channel. The LCD display
indicates when a signal is being received on a channel, irrespective of
any CTCSS code and a press of the monitor button will make audible all
communication on that channel. We've seen some misleading
advertising indicating '304 channels' - gained by multiplying the 8
channels by the 38 CTCSS codes. Ohhh, naughty! At the end
of the day there's still only 8 channels!
In the following year on our 2004 Scotland holiday we found the
talkies to be a godsend in the cottage. The kitchen/conservatory
distance was beyond shouting range, so the 2 way radios were ideal
for Belinda to order a tea/wine/cider while Mike was slaving away in
the kitchen preparing the evening meal! A slight irritation is
the impossibility of standing the radios vertically owing to the
rounded styling and one thing we noticed after a year's use was minor
dust build-up behind the plastic over the LCD display.
Other uses we found for the talkie walkie radios include:
Other suggestions:
Any other points
The 2 way radios have a button lock, eg. to prevent
inadvertent channel change, and the key tones can be turned off.
An auto power off feature to save battery power if not used for a while
is available as is a stopwatch timer. It's possible to use dry
cells (or higher capacity rechargeable) in place of the pack provided
as the talkie walkies take four standard sized 'AAA' cells. In
this case it wouldn't be possible to use the drop in charger pod.

Overall conclusions
The Binatone MR600 two way radios (or three way, four way or however
many you wish) are a very useful communication method over short
distances. However, that distance is severely limited by the low
power and aerial constraints governed by the PMR446 licence free
regulations. While our Binatone talkie walkies are adequate,
there are undoubtedly better units around and if in the market again
we'd do some more research before purchase. That's about it,
Alpha Brava One over and out!
It's 2010 - so no updates in six
years?
Er, no. We've not seen a need to update this review as the talkie
walkies have largely continued to work as tested since our
review. If pushed we could report that the dust build-up has
continued behind the display, and the batteries don't last quite as
long between charges, but that's about it! No failures and
nothing's fallen off.
However, our Binatone MR600 talkie walkies have become a bit battered in use so in early 2010 we looked to see what's available to replace them... ...and came up with the Binatone Action 950 two way radios - see our review.
