Old black and white TV and digibox connections

In this case, it can only be made to work if you find a digibox that has
a built-in RF output ( modulator ).

This will put the digital channels on an RF channel, which the ageing
hulk can tune into.

On the digibox I have an " ant in" and a " TV out" pair of sockets aside
of the scart.
Are those any use?

It depends [TM]

Most (all?) digital boxes have "loop through" where they will pass
the RF signal from the "ant in" (from antenna, this is American usage,
in the UK we call it an aerial) through to the TV so that you could
use the TV's own tuner.

Whats an RF channel?

RF is radio frequency, this describes that part of the electromagnetic
spectrum used in TV and radio transmission. TV signals are transmitted
on certain frequencies and these are called RF channels. Analogue
television uses one channel per service. The output of some digital
boxes can be transmitted down the lead connected to the "TV out"
socket.

I still only have an aerial
socket on the TV - so only one way in to the TV.
How could it be wired up if I got the right digibox?

Plug in the lead and tune the TV to the output. You may need to select
a non clashing channel from the digital box's menu.

I think you need an external uhf modulator.

I am sorry , its me again. Totally unrelated to my new TV question and HD
ready. I read in a magazine that any TV , even a fifty year old b/w one can
be connected to a cheap digibox and made to receive digital even if it
doesnt have a scart socket.

How do you do this? I have an old Sony b/w portable TV from circa 1974 .
It still works ( or would if we had an analogue signal) . I also have a
digibox here ( Tesco's own about two years old) . How do I connect it
up? I cant see anywhere to put any leads in , even if I had leads. There
is no scart connector on the TV . In fact all there is as far as I can see
is an Aerial socket to put an external aerial on the TV.

Can someone tell me if I can convert it or if the article was wrong?
Thanks.

I realise it may not be a perfect solutions and somewhat messy under
the TV, but how about an old VCR? Scart from the freeview box into the
VCR and Coax out to the TV. That should work OK.

It won't be a messy solution if the OP already has a VCR and still uses
it to play tapes! I feed an old but very good 27" CRT TV from a VCR,
with one aux input connected to a satellite receiver and the other aux
input to a DVD player. Hence the VCR works as a scart switcher as well
as an RF modulator and video-tape player/recorder.

If I got such a box, how would that connect to the TV? Through the aerial
connection only?
There is absolutely no other place to plug anything into. It would be some
sort of wire with a aerial type connector on it?

Can I just check, you have a loop (or telescopic?) aerial effectively
hard-wired into the TV, with not even a small "plug" somewhere on the back?
Often the portable aerial ended in a small plug which you could remove to
reveal a bog-standard TV aerial socket, into which you plug your
modulator/freeview box.

If you DON'T have such a socket, then you will need to effectively unwire
the aerial and attach the modulator/freeview box through the cable, possible
via a balum to match the impedence (cue old-timers/experienced installed
like Bill Wright to comment as I'm sure they've seen this all before!).

My reading of the OPs remarks is he knows full well where his
aerial plugs in and (quote) "There is absolutely no *other* place to plug
anything into"
(my emphasis).

I think I saw some Freeview boxes in Tesco with modulators recently,
Not cheap, around 30 pounds IIRC.

Only a small number do, others can advise which models.
But what they didnt say , if I read you correctly, is that I need a
special digi box?

You need one of a few digiboxes that has an RF output (not just an RF
through connection,)

TVonics MFR-200 Black Digital Set Top Box. 532/1375 is one that Argos
do. £38.99 so not terribly expensive. The old On-Digital boxes also
had RF output if you can pick one of them up s/hand.

It would appear that the OP is asking simply because he 'already' owns a
cheap Tesco digibox and an old b/w TV, however I suspect that it's highly
unlikely that he would wish to spend around £40.00 on converting a 1974 14"
black and white television to digital when he can pick up a 15" flat screen
colour TV with built-in Freeview for under a £100.

Some digiboxes will output a signal via the aerial lead so can be used with
any TV.
The technical term you are looking for is one with an RF modulator.

But you do save about £60 a year on a b/w TV licence

Assuming of course that he doesn't have as his main TV a large screen colour
TV.

Unfortunately it's hard to tell whether a particular STB has such a beast...

Purchase a TVonics MFR-200 or MFR-300

http://www.tvonics.COM/digital-set-top-boxes/mfr-200.html

http://www.tvonics.COM/digital-set-top-boxes/mfr-300.html

Connect your TV antenna coxial downlead to the antenna input of the digital
coverter box, and then connect the RF coaxial output of the digital
converter box to the antenna input socket of your Sony portable TV.

Tune the Sony portable TV to the output channel of the digital converter
box (see instruction details for which UHF output channel is used),
and then use the remote control of the digital converter box to
change channels to the desired terrestrial DTV station.

Note that your picture will only be monochrome and the sound monophonic.
However, if you connect the audio output of the digital converter box
to a pair of powered speakers (or your stereo amplifier with speakers),
you will be able to enjoy the stereophonic soundtrack of the digital
TV stations.
