#57201 — Weird pulsating carrier on fm

SubjectWeird pulsating carrier on fm
Message-ID<s677jq$pki$1@dont-email.me>
Around here on 88Mhz exactly There is a silent carrier, on for a few 
seconds, then off again, with a decided wobble at on and off producing a 
high pitch farting noise each time. I have wandered around the locale and 
its very strong, stronger than the pirate station beneath it and wipes it 
out when its on.
 It has some odd bits of itself at lowered frequencies but I guess these 
could be mixing products because its so strong, I can even hear some on the 
4Mtr ham band.
 Anyone know what it might be? Normally when you are testing a transmitter 
you leave it on, not turn it on and off for  many days so far, but it may 
have been there for ever, who knows. I looked at it in am and using a bfo 
that is how I know its dead on the frequency.
 Mighty strange.

You've got to remember not all of us remember where "here" is.

Are you talking a small number of seconds, such as three to six, or more 
like 30 to 90? Are the on periods and the off ones about the same? Is 
the wobble AM or FM? (I presume FM as you're hearing it, presumably with 
an FM set.)

Ought to be possible to make a directional aerial - at least, with 
directional nulls - to help you hunt it. Might need to connect it to a 
receiver in a screened box if the signal is as strong as you say. 
(Obviously take care, including accepting sighted help if necessary, 
when hunting.)

Are sure that isn't the fundamental?

Depending on how accurate what you are beating it against is, of course.

OK Here is Chessington in Surrey or London depending on your view.
 Its less than ten seconds and does not vary. I'm using an Icom 
communications receiver so its pretty accurate.
 I've listened to it in am and FM, That is how I know there is a pirate 
under it, but weaker, as I had considered a jammer.
 The wobble is as you would get if you were powering something up and then 
turning it off, it eventually stabilises and there is very little if any hum 
in am or fm.

No the 88Mhz is far the most powerful carrier. I'm using a discone aerial, 
which has no particular preference in its receiving properties between a 
whole range of vhf frequencies, but may of course have some lobes  at 
different frequencies that you may not be ale to discern.




Its right on the edge or indeed inside the fm band, so is hardly going to be 
coms related, unless it is some spurii generated by some piece of equipment 
locally, but to have such a wide coverage it sounds like it has a proper 
aerial or it would be patchy. Trying it on a cheapo portable fm set its 
still present, so is not some artefact in the receiver either. I have proved 
its not in my place by walking some distance away down the back ally.

You could try ringing OFCOM.  In my experience they will deny its
existence and then it will disappear.  

I heard something around 144 Mc/s a few years ago, it was geographically
very widespread but could have been coming from a military area.  OFCOM
tried to tell me it was due to intermodulation in the receiver (an
Eddystone 770R on a poor aerial !!!) - it vanished the following day.

I would not know where to start for that one.
 Its still there this evening. I really need to take a portable with my when 
I go a bit further field we are on the edge of an industrial estate, so it 
could be coming from there.

You want to hurry up else it will stop and we'll never know.

Is it 24h? (If not, that might affect whether people can join you 
hunting it - it'd have to be on when they're free.)

>communications receiver so its pretty accurate.

As accurate as its various crystals; I doubt they're ovened, so - I'm 
out of touch, but from what I remember non-ovened will get you something 
like 5-10 ppm (before ageing). (Unless it's locked to a broadcast 
standard.) 10ppm at 88 MHz would be 8.8 kHz. Though this doesn't really 
matter for the purpose of this exercise.

If you really can't find someone to go DFing with you (I'd have thought 
it'd be quite fun, in this sunny weather): has your discone any nulls 
you can determine? Failing that, can you make up something - a dipole on 
a pole, if nothing else? Note that nulls are often much sharper than 
maxima, certainly with a dipole.

Inside: IIRR, band II starts at 87.5 MHz.

Can you put your "cheapo portable" in a metal box (old Christmas sweet 
tin, biscuit tin, etc. - at 88 MHz, the seal wouldn't have to be that 
good), and connect it to the directional aerial, so you can go hunting?

Could you go further - e. g. accompanied by a dog walker or similar, to 
help you with trip hazards, traffic, protection, etc., or is your health 
not up to that? All assuming you can't find a local ham group or similar 
who I'd have thought _ought_ to be very interested in tracking it down.

I found one interference source for the Radiocommunications Agency (I 
think that was their name at the time) by using a fairly basic hand 
scanner and driving around the area. When the signal got strong I took 
the antenna off.  I got to within a couple of houses.

(They had tried to find it but failed).

Maybe just maybe, you have a more anarchistic mindset;?...

Knowing where you might put such a device?..

It was almost certainly an unstable head amplifier on someone's TV 
receiving antenna.

The Gibberment agency would probably have just fired up a couple of 
their listening stations, not been able to get a decent location on the 
dials, and couldn't find their mobile rig, which was probably sorting 
out a problem for Her Majesty in Balmroal or wherever she was having 
trouble getting Corrie that week.

There is a remote aerial on the hillside for the castle.  I checked that it
worked many years ago.

Though with old police radio system, the repeater for their PRs was 
initially set up to Tx and RX the wrong way around.

No one at Northern Police realised that Scotland operated the opposite 
way around to England and Wales!

They do get out and about, this one was on Barra and they had been over 
but did not hear it whilst there.

Another case that I helped them with, appeared to around Stornoway and 
they had been there but again been there but not heard anything which 
turned out to be because he was in Inverness.  A friend heard a very 
strong signal there so they parked one of their trailer mounted 
monitoring units there (at a secure site).  They must have been able to 
DF because someone was charged with WT offences and theft.

It can be imagined that sometimes it can be someone in an area hundreds 
of miles across and that take a couple of days to reach.  With someone 
operating intermittently, it is very difficult to find them - the second 
one only operated when there were no clouds!

This is why they often find it useful to get help from people on the 
ground.

I found a hooting head amp in Kyleakin and passed the details on.  Worst
one was one of the "Home Office masts" sending a signal, that wiped out BBC
1 in Kendal.

Your job must have brought many moments of high amusement.

yes, but some other moments that were the opposite
