An opportunity for Manhattan’s new Freeview box
A
s Sky switches customers
from satellite dish reception
to online streaming, there is
a growing park of satellite dishes
ready, willing and able to deliver
free TV and radio via the Freesat
service – which is roughly equivalent to terrestrial Freeview. The
main difference is that Freesat has
some extra free channels (100+ in
all, with 35 in HD).
So now seems a very good time for
the industry to sell Freesat receivers
and recorders. That’s what makes it
so strange that Humax, one of the
pioneers in satellite reception, has
quit the Freesat market. But this
has created a big opportunity for
Humax’s main rival in the “Free
TV” business, Manhattan.
So it was no surprise that the
30-year-old British company recently announced a new Freesat
receiver/recorder to match its existing Freeview recorders. The S4-R
Freesat 4K TV Recorder is Manhattan’s fourth-generation Freesat
device. Conventionally, it has two
tuners to record two program channels at the same time from a dish
with two LNBs.
However, if the dish has a more
modern wideband LNB, as used
for Sky Q, the S4-R can ‘tape’ four
channels at once. This is possible
because a wideband LNB outputs
all the vertically polarised signals
via one dish feed and all horizontal
signals via a second dish feed. A
smart receiver/recorder, like the
S4-R, then decodes the two feeds
into four program channels.
Personally, I prefer to use the
original type of LNB, but with
four (Quad) or eight (Octo) F-plugs
(instead of the usual two). That
way, I can run separate satellite
feeds to receivers and recorders in
different rooms, with spare feeds
to check dish alignment by testing
signal strength.
As the name suggests, the new
Manhattan Freesat box can also
handle 4K Ultra HD, if and when
4K broadcasts are available, or
when streamed.
The current Manhattan model
has an onboard 500GB HDD, with
1TB and 2TB versions to follow,

giving 300, 600 or 1,200 hours TV
recording time. Live TV can be
paused for up to two hours and
rewound, too.
The user interface is clean and
clear, disinguishing between live
TV channels and on-demand
content from streaming sources
such as BBC iPlayer, ITVX, Channel 4 and 5. For copyright reasons, the streamed content cannot be recorded – just as Freely
streams cannot be (legitimately)
recorded.
(Tech literates will of course
already be aware of the low cost
HDMI-to-USB capture dongles,
which are widely and openly sold
online to connect a receiver to a
PC running free capture software
like OBS).
Pricing for the Manhattan TV S4-R
500GB model is £219.99, £249.99
for the S4-R 1TB and £279.99 for
the S4-R 2TB.
The box has both Ethernet and WiFi
Internet connections and an optical
S/PDIF socket for digital audio output to a soundbar or hi-fi system.
There’s a clear instruction book
printed on good old-fashioned
paper – not just a weblink to an
online manual.
I found setting up the Manattan
Freesat box easy and intuitive, with
no need for the manual. During
the process, I discovered a valuable diagnostic tool buried in the
interface.
When I plugged two dish LNB
feeds into the receiver’s two F-plug
sockets, the set-up screen warned
that there was signal from only one.
This suggested a bad connection or
open circuit in one feed.
But the screen also showed an
“LNB Overload Detected” error
message. I’ve not seen this before.
Manhattan’s helpful Help explained
that this message means the LNB
feed is drawing heavier than usual
DC current from the box, probably
because of a short circuit in the
feed cable, between the signal core
copper and outer braiding.
Armed with this simple clue, I
tracked the cause down to a short
circuit in one of the dish feeds.
Once this was repaired, the error
message disappeared and highquality pictures appeared.
I also had problems connecting
the box to my fibre broadband. A
different error message helpfully
told me that the box was connecting to my home network but not to
the internet, either via an ethernet
cable or by WiFi. But other equipment on the same network was
working normally.
It’s unclear why this happened.
It could be related to the IPv6 settings on my router. I’ll probably
never know because the problem
self-solved when I played the usual
trick of shutting down and rebooting everything on the entire
home network, to create a whole
new stack of dynamic IP addresses.
As the IT Crowd always initially
asked their helpline callers, “Have
you tried switching it off and on
again?”
Perhaps it would make sense if
all error message for all equipment
now routinely offered similar offand-on-again advice.
Bottom line conclusion: Even if it
weren’t one of the few Freesat boxes
left to buy, I’d be wholeheartedly
recommending the Manhattan S4-R.
Vape-powered drones
I’ve previously written about the
free source of lithium-ion rechargeable cells littering our streets. Every
discarded single-use vape contains
a good-as-new battery. As long as
you use a safe charger designed for
lithium-ion cells, several cells in
parallel make a very useful power
bank.
Since the sale of single-use vapes
has been banned, there have been
fewer and fewer discards to pick up.
But there are obviously stockpiles
of unsold vapes, and they are now
finding a good home
A workshop in Ukraine is ganging batches of around fifty cells
together to make a battlefield power
bank, or using smaller clusters to
fly drones.
The story is here to read, with
some videos which (hardly surprisingly) don’t reveal much about
the manufacturing process: https://
