| 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. Brian -- This newsgroup posting comes to you directly from...

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. -- ~ Liz Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk

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.

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;?...

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.
