Hello and thank you for the comment. I am interested in the "5G radiation shielding blocking hat spring knitted" and it could have been good to buy one, just for the laugh. Of course it would be completely sold out. If you want instructions for making a classical tinfoil hat then I found this link on the web: ruclips.net/video/Zr8u7br5V3Y/видео.html I am sure that the human race is obsessed with circlular motion and have been so for 10,000 years. Your comment on Don Quixote finding an (unsuccessful) use for them was interesting. I must do a bit more googling, probably have more to learn. "Is the history of human civilization spinning in a spiral?" Very probably. At the moment we live in unstable times and history seems to be repeating itself with growing violence and wars. But perhaps this is a soapbox I should not climb on. Thank you very much for taking the time and trouble to respond to my videos. I really do appreciate this. Very best regards from Harry Lythall, Märsta, Sweden.

Thank you very much for the positive response. I really do appreciate your comments. It is also nice to know that you are a follow of HHH :-) I have two more videos ready to publish and they will probably be up tomorrow morning (Monday): RF Safety parts 1 and 2. I have many more videos in the pipeline, and not all are related to RF. Very best regards from Harry

Nem Bruno, obrigado pelo comentário. Espero que tenham gostado do vídeo (c). A Nike quer ouvir notícias de Portugal. Atenciosamente de Harry - SM0VPO Hi Bruno, Thank you for the comment. Hope you liked the video(s). Nice to hear from Portugal. Very best regards from Harry - SM0VPO

Thank you for the comment. It is always nice to know they are appreciated. Very best regards from harry - SM0VPO

Hi, It was a little experiment, and I wondered if it may look a bit silly, but it seems to have worked. My studio is a bit small so I have space restrictions. I am really pleased that you liked the video and took the time and trouble to leave comments. All comments, positive or "constructive" are always welcome. Very best regards and I hope you have a Happy New year - from Harry - SM0VPO

Hi, I suppose a lot depends on the minimum you expect from an analyzer. The analyzers I used professionally were in the region of $40,000 to $100,000, but they worked up to the 50GHz regions, and could decode 5G Cell-ID, SSB, and get stable level data. As soon as you talk about constellation diagrams and >10GHz the prices seems to rocket. For my own lab I chose the Siglent SSA3021A analyzer with a range limited to 9kHz to 2.1GHz, and has no signal analysis, other than the basic SA features. It also has a good clean tracking generator that I use regularly for filter design and testing. Yes, for $200 you can get a simple and effective instrument. I have a Raspberry-Pi with a colour display and an SDR dongle. It makes a great OTA monitor and QRM-hunter, but it is somewhat limited on the workbench. Measuring down to -120dBm is a lot to ask, but the Siglent can do it. Anyway, thank you very much for taking the time and trouble to respond. I really appreciate your comments. Sorry if I was a bit verbose with my answer. Very best regards and I hope youhave a Happy New year - from Harry - SM0VPO

Thank you, I am so glad you like it. There will be more to come. Very best regards from Harry Lythall - SM0VPO

@@harrylythall3486 we can’t wait 😌

Hello Jexx7373 The next video will be "RF Safety", but I intend to have a bit of fun, shooting down myths and tinfoil hats, as well as being serious. It will be a bit funny, but it will cover everything in the radio spectrum. The storyboard is already written, I need to record it, then spend a couple of weeks clipping: that is the bit that takes the time. Thank you once more for your comment. All comments are greatly appreciated. Very best regards and I hope you have a Happy New year - from Harry - SM0VPO

Hey up lad! Watter? Dunno, I 'aven't tried watter. Good comment though, water could be really good - no burnt stuff to poison you. I have loads of empty vapes here so I may just give it a try and see what happens :-) Thank you very much for the suggestion - really appreciated that you took the time and trouble to leave a comment. Have a nice day - Harry - SM0VPO

Hi George, Thank you for the info and taking the time and trouble to leave a comment. Yes, I feel it is a sin that these are simply thrown away. I have loads of them, and the guys at work used to give me their old vapes. I will see if I can find your channel and take a look at your videos."Make Do and Mend" sounds promissing. It will be interesting to see what you have been doing with them. I once read that men over 65 years old use 3x more super-glue than men from 20 to 65. That tells a story, the older you get so the more you fix things ;-) Very best regards and 73's from Harry - SM0VPO

@harrylythall3486 My youtube is called George and Jane Motorhome Adventures. I have also re-used gas bottles that are scrap for Cavity Filters for uhf repeaters. Videos in my Ham Radio playlist. George 73's

Thank you very much for the comment. I am so glad you found the information useful. I have a question for you, do you think it would be a good idea to make a video about charging LiPO cells when they are series coupled? Without using a "special" charger? Or was your primary interest in refilling e-cigarettes? LiPO cells are notorious for burning, if the charging is not properly done. For example, many of these 12-Volt drills/screwdrivers use NiCAD or other cells, series connected, without charge balancing, so after 6 months you have to buy a new battery pack. I have developed several techniques to balance cells without a "special" charger. Do you think this be a good idea for a follow-up blog? Or were you happy with the vape-video? Very best regards - Harry

Hi Harry, I think your idea to make a video on how to charge vape batteries without a special charger is interesting. Vape batteries are a little treasure that are lying around everywhere and can be effectively used in our daily lives as a portable source of electrical energy. P.S. I am 62 years old, I smoke tobacco, cigarettes and cigars, drink gin and whiskey and use traditional swear words in my speech.

Ok, you are not the first to suggest this, it was not actually my own idea, but a suggestion from a friend. I think I will go ahead and make such a video. My studio mic uses two cells, so I used a DPDT switch for the ON/OFF switch. It switches OFF the amplifier, but also re-wires the two cells in parallel: - the audio jack GND is the battery -ve and the +ve terminal is connected tot he isolated switch chassis so I have access to both cells for float-charging @ 4.2V - no need to balance - If one cell has a lower capacity, then in parallel, the cell with the highest potential will float-charge the other so they become balanced I also use two miniature relays in my Hamradio Transciever so that all three cells are in parallel and I can charge the radio with a 5V USB (which energises the two relays). Unplug the USB and the 12V to the radio is restored when the relays drop out. No cell voltage balancing needed. In my (cheap) battery drill I put a darlington transistor and voltage divider across each cell, so now each (NiCAD) cell is overvoltage/charge protected with just 3 components. The cells are now charge limited. I deleted the in-built obsolescence! I have lots of ideas. Ok on your personal circumstances - I am 73 years old, recently single, and I stop smoking regularly. I love a nice single malt (speyside is my favourite) and I also use "traditional language", but in moderation. The Swedes often have problems understanding "coloquial English" and typical English sarcasm. Thank you for replying. Have a nice day - Harry

I suppose it does count as a QSO. QSL? So glad you liked the video. I am working on two more at the moment, but I keep getting distracted with other things, such as getting snowed in 100km North of here, shopping/washing ... I often wonder how I had the time to go to work.

Thank you for the comment, I am always learning more, but the problem with knowledge is that you have to be old to get it ;-) It was my old radio teacher at RAF Locking (Mr Horry) that gave me that snippet of information. He said is was Shellac. Really appreciate all comments. Best regards - Harry - SM0VPO

Hello, and thank you for your feedback. I really appreciate your comments and I am so pleased that you liked the presentation. I worked with multimedia for Ericsson for over 10 years and they used me in more than 650 videos. They thought that a Northern English (Yorkshire) voice sounded more friendly than an American accent, and living in Sweden I learned to explain things clearly using more simple words. Very best regards from Harry Lythall - SM0VPO (Brit in Sweden)

I am so glad you liked it. I am already working on the next video "What is RF?". Thank you for taking the time and trouble to leave a comment. Best regards harry - SM0VPO

Thank you Steven. Forgive me for asking but I am still new to this and it is not easy to make a video that is informative but concise. There are also a few bits of side information. I cut out a lot of "off track" information to get the video down to the current length. But thank you for response. TÍ am really grateful. Best regards - Harry - SM0VPO (Sweden)

Thank you very much for the feedback. I am so please you found it interesting. Please tell your friends, the more likes and followers I get so the more videos I can produce. Question for you, what did you like the most about the video? What was the best or most interesting information you got from the video? Very best regards and thank you for taking the time and trouble to respond to me. I really appreciate it. Bery best regards - Harry - SM0VPO (a "Brit" in Sweden)

Hi Jim, That is an interesting thought. I already have some knowledge of the development of millimetric wave and Jagadish Chandra Bose sounds like a good topic. I shall look into it. Thank you for your comment. Really appreciated. BR Harry

Hi, so glad you liked the video. I used to do this sort of thing professionally between 1999 and 2010. I wrote mqanuscripts for over 800 similar films and I presented over 750 of them. At the moment I am struggling to find a decent video editing program, but I am using OLIVE. I have about 8 or 9 videos planned. The next video storyboard is complete, the filming has been done, and now it is about 60% clipped. So glad you liked the soldering videos. They are on my list to update and present in a better HD format. Unfoirtunately they are hidden from me - RUclips cannot be convinced that I am me so I have no access to them. This is why I have the new RUclips channel. Thank you very much for your comments. It is nice to know that people are watching my first of many to come. Very best regards from Harry - SM0VPO

Hi Dylan, Many thanks for the response. Yes, I was taught a lot about "THE" history of radio, but with recent research I found that which we are taught in school is not always accurate. A dentist making the first wireless transmission is not really acceptable to many, A russian who first used oscillations did not go down well with my radio teachers in 1968, and Marconi getting patents because he had the best lawyers may not be so ethical, but history has a nasty habit of being "revised". In the millitary radio school they pounded into use that light was magnetic waves, but after asking why light is affected by gravity and therefore has mass, was told to shut up. No explanation!! I do not want my videos to become political, but I will present as much information as I can and see if I can enlighten people. The first video took a lot of research. Thank you for your comments, all comments and constructive criticisms are always welcome. Have a nice day and best regards from Harry - SM0VPO

Thank you Adam, I have already recorded the next, but now I need o clip it and insert explanatory pictures. The next will be better, slightly longer (23 mins), better qualioty video and sound. Thankls for the comment. BT Harry

That is the most common interpretatiojn, but I will tell you in the next video 🙂Thank you very much for taking the time to comment. Hope you enjoyed the video - Harry

I had to come back. I lost my job in January, so I was forced to take early retirement. Now I have more time to do this sort of thing. Renovate parts of the house, build a 3D model RC boat, build a video studio, you name it. I do not want to sit on my bum waiting for death. I produced about 750 training videos for Ericsson, so I think it is fun. Thank you for taking the time to comment. est regards - Harry

Thank you very much for the comments. Flattery will get you everywhere 🙂 Maybe I don't look so bad for a 73 year old? The previous videos I made were more a "spur of the moment" occasion, and they looked amateurish. Now I can make videos properly there will be more to come. I think I need to smile more. Best regards from Harry - SM0VPO

I intend to do just that :-)

Hi Steve, Thank you, that is praise indeed. hope that you will see more of me on RUclips. I have already written 1/2 the manuscript for the next video film. I really want to promote my channel, and make more professional videos. I also want to try to prove several "well known" facts that are wrong (like Marconi invented radio). I never promoted my RUclips channel much before so now I have to work at it. I hope that you will find the next video (with better sound) as interesting. There are some surprises planned to provoke comments. But thank you so much for commenting. Really appreciate you taking the time and troubls. Very best regards from Harry Lythall - SM0VPO

Hi Dick, Sorry I missed your comment (the only comment of ths video). Now I am retired you may see a lot more of me in other videos. I have buil a studio in my home and started to produce (what I hope are) interesting videos. I published the first of 9 planned videos only today. BR Harry

With every job in the house I ALWAYS seem to need a "YAFT" (Yet Another F'in Tool". This takes some practice, and the offcut is always smashed to smithereens, but if you get it right it works. Not always perfect but a sanding block can usually fix that. I was lucky that the previous house owner had left 100's of spare tiles, but I got the job done, without buying a YAFT.

You wrote "Have you worked out which containers aren't suitable for making jelly yet?" So you know me well. You have heard of my "jelly in a milk bottle" error? I will never live that down.
