Youtube hearted comments of Bond25 (@Bond2025).

  1. One thing that was popular int eh 1980s was "PIRATE TV". I bought a TV transmitter known as a "Video Sender" in the late 80s to transmit the output from a VCR around the house to TVs. I still have it to this day in a box and it still works! People would use them and then leave them on broadcasting films. You had to know about them or find them by chance when tuning around. There was someone local to me that did this at weekends and must have been using a computer generated test card. It was one film after another, no contact details. The output was only around 10-20mW on mine, so I suspect people were using amateur equipment for a bit of fun to amplify them. I never used mine this way as connecting it to a TV aerial wouldn't have got far, only at the back of all the other TV aerials ! In those days I knew nothing about RF, so nothing about UHF aerial designs and the Internet wasn't a thing then. It still does CH21-68 analogue with a video in and audio in plug. If I could have turned the aerial around to face everyone elses I might have tried it out. It was definitely possible to interfere with TV for a few houses nearby using the small telescopic aerial.

  2. The Lindenblad type aerial, awful things in my opinion. 4 dipoles in parallel at 45degrees means a huge MINUS dB figure and having to use fairly big power amps to overcome the loss and achieve a reasonable ERP. I really wouldn't waste my time with one as coverage is nowhere near as good as a stacked dipole arrangement or stacked circular polarised aerials. Why put 600Watts in, waste all that electric with much bigger power amps, splitters and coax and have less coverage than using 4 times less to get the same coverage for stacked circular polarisation aerials OR 6 to 8 times less through a single dipole! I've never understood why people want circular polarisation now anyway, vertical is how most people have aerials. Even horizontal has died out.

  3.  @RingwayManchester  When you returned from the toilet, your table had gone! Most people went at night when it was dark, but it still give great views. You can go further along the Strand in to the hotel and sit right at the top of it.

  4. There were two serving estates at the end of the M53, but I can't find the exact details. I think they were on the MB21 site. People were wondering why there were two TV aerials on a lamp post. One was a horizontal group C/D pointing at Winter Hill, and underneath was a vertical Group A pointing to two estates by J2/3 M53. This was analogue TV. Another filler repeater was by J1 M53 and outside a council tip on a lamp post, same arrangement, Group C/D horizontal towards Winter Hill and Group A vertical to local area or housing. The power output was only 1 or 2 Watts and 5 channels when in operation. Maybe anyone local can have a look or confirm this. The M53 J2/3 one was no longer required when the Storeton Transmitter (M53 J4/5) went on air. People could use that, including a lot of people in Liverpool who were line of sight and a mile or two away compared to Winter Hill. The only problem was they got S4C and not Channel 4 as it was installed to transmit to Wales, not Wirral and Liverpool. That might have changed now. Moel-Y-Parc still doesn't cover all areas despite it's presence. There were lots of these smaller TV repeaters about in the days of analogue, most not on big masts. One or two appear to have been unofficial, set up by people to help locals out.

  5. Good job they didn't know about people using amateur radio equipment to tx/rx... loads of people listened to police up until around 2004 around here. They didn't realise other frequencies were used and locals used scramblers. I had a kenwood th42e in 1994 that didn't only cover 430-440 if you voided the warranty and modified it. Imagine the chaos we would have now with all the cheap Baofeng radios.

  6. I can't tell you how much i dislike those lindenbladd type antennas! In my experience they are not efficient and can easily be outperformed by most other types. A few stacked dipoles outperforms them using much lower power. Circular Polarisation is not effective at VHF. Why have a massive minus dB gain and have to put 6 times the power up the coax, then have slanted radiation which just doesn't work well.

  7. There was a Merseyside MW station that saw DTI people and dropped an old fridge off the balcony of the flats! One station found that the door intercom on the block they were in was playing the station audio as the TX was around 100Watts on Medium Wave.

  8. I might have to mention another system you are probably not aware of that was given the project name "CELLDAR". This was tested in the mid 1990s and a Gov Dept using a company name of Roke Manor Research had various test facilities, including a large stately home. The basic idea was to do something with the reflected waves from high frequency transmissions emitted from cellular phone transmitter sites. The reflected waves built up a 3D model that was fairly crude, but showed anything moving within the space monitored as it interrupted it. It looked more like a waterfall display you see today on a SDR. The early tests showed a blob moving, not even the shape of a person, there was no real definition. The aim at first was to use it for passive aircraft RADAR, but it didn't work due to the frequency and downward tilt on directional aerials. Lower frequencies from broadcast and TV stations could never work. It had to be a short wavelength. It improved to a point of being able to detect people and vehicle shapes and worked in built up areas better. The project was stopped as the results could never be improved upon and would never give the definition required.

  9. It's obvious what the people that followed him were like, mostly supporting his vile and criminal behaviour as it has now been proved in court. Only scum criminals support other scum criminals.

  10. 4:54 that drives me mad, the aerial for Capital has been mounted upside down. It's changed in recent years as it only had one element and the power level was a lot lower. 378Watts is odd, maybe to overcome the length of feeder loss and the -dB gain that aerial has, they are horribly inefficient and I am not sure why people still use them. All that wasted power to radiate the same signal I can get from a mixed polarisation aerial with 100 Watts to vertical and horizontal.
