Welllllllllllll
Three days work and all for nowt
Let me explain
I live close to a factory estate, and in the various units they use all sorts of gear.. Electroplating baths, welders, BIG lathes, electronic packing gear, automated robotic assembly lines... You get the picture....
All this means that I am close to a vast array of interference... So much so that back in the day when I took it all sooooooo serious, I would pack some gear in the motor, drive a few miles and set up a 'portable' radio station as it was, and still is, the only way I could receive any stations that were not giving a really strong signal

For those who may have used CB radio ( or indeed are short wave listeners of hams ) the 'noise' level ( interference ) is always S7 to S9 on the meter ( for those unfamiliar the meter in question show the strength of the signal you are receiving.. It goes in steps, 1 to 8 and then there is a section above the 9 showing the strength in dB relative to an S9 signal
As you can imagine, a base level of interreference reaching an average of S8 severely impeded my ability to receive signals except from really strong stations

It has always been the accepted wisdom that vertical antennas are less prone to man made ( what is referred to as QRM ) interreference
Seems I have proved without a shadow of a doubt that it is not always the case

Spent the morning fine tuning the antenna and was quite pleased with the result ( an antenna's length is critical and has to be adjusted to 'match' the frequency it is to be used on ( again, those who have used a CB radio will be familiar with this concept as at some stage they will have come across SWR.. Standing Wave Ratio, which ensures what you transmit goes OUT and is not bounced straight back in to your radio )

Ran the coax up to the radio shack and in to the radio
On every band the received signals were exactly the same as those received on my existing antenna ( G5RV for those interested ) but the noise levels ( interference ) rose !!

So sadly, as I said, it was all for nothing and I will be adding a rather posh multiband vertical antenna to the for sale list :(
Just a thought (from a one time Radio Operator) an old friend of mine was a keen radio ham, unfortunately his house was at the bottom of a dip, he bought the biggest aerial he could get but that didn’t improve things much, he suddenly struck on an idea, as he was ex RN he decided to purchase a flagpole & a Royal Ensign, he put the antennae at the top of the flagpole & enjoyed a much better reception.

Not all antenna benefit from height .. A vertical requires something called 'ground effect'.. This is usually achieved by having radial wires spread out on the ground to 'counterpoise' the radiating part of the aerial
For instance, a car aerial requires the body of the car to work properly, which is why fibreglass cars are sometimes problematic
Yes, my G5RV wire antenna would def be better higher, but realistically 30ft is the highest I can go without seriously peeing off neighbours !

Started some more of that welding/making stuff game and guess what .......................... that brand new not very cheap welder went pop after a 3 inch weld I am absolutely raging :mad:

All I can say is its a good job it was an online purchase as no local shop is going to want me in there "complaining" at the moment

Only if it is used for a flag. I obtained an open certificate that allows me to erect any 'reasonable aerial structure for experimental use' many years ago
I am also on the local councils list or coms locations in the event of a disaster ( proper double edged sword that is too ! ) even though I am NOT a member of RAYNET

phoned up parcel force again as my parcel hadn't arrived again, it seems something called Christmas is causing the problem

Did a walk with friends, then coffee

Yesterday :

Audit meeting at work with a chap from near Cappoquin - I'm betting Squag1 knows him :)

Today young lad hit the car driver's door mirror when I was parked. Unfortunately it's cracked part of the plastic retraining clips built into the housing so the glass/motor aren't broken but won't clip back in properly.
He did stop, has offered to pay directly and sent an email accepting liability and undertaking to pay repair costs.

I won't be able to look properly in daylight until Saturday. It's possible that the clip is part of the rear cover so it could end up being a really cheap fix.

On that subject, can you give me the number for the complaints department at Thetford Council..... I'd like to lodge a formal complaint regarding the shadow it casts over our house.

Well, I couldn’t bring myself to take the pup back to the dogs home as I can’t stand the thought of stressing him out further and him losing more weight that he really can’t afford. I phoned them and asked if it was ok if he had a sleep over and they’re as happy as we are*.

He went through a total of 900g of dog food today (Gia is on 500g/day), half of Mrs P’s cheese buttie and a quarter of my Marmite PB toasted buttie.


*Mrs P isn’t happy right this second; she’s sleeping on the sofa in the lounge with the two of them in the room. Gia sleeps in there anyway but we didn’t really want to put the pup in there just yet but he won’t settle upstairs on the landing. Twat.
