Nice thorough review, Chris!

How do you change the oil, or check the carb?

One of the major failings of this generator, which is well illustrated in the video, is it being a right pain in the butt when trying to start it. Mine used to take about 20 pulls before it would run. The basic problem is the level of the fuel in the fuel tank with respect to the carburettor. Because the fuel tank is mounted on the side of the unit, rather than above as most small genertors are, if the fuel level is anything but absolutely full then the internal fuel lift pump has to get fuel up to the carburettor before it will run. The lift pump is operated by crankcase pressure and one has to do multiple pulls to produce sufficient lift. If the tank is brim full then that problem is eliminated. I've done a small mod to my machine by fitting an auxillary high level priming tank made from a short length of 22mm copper tube. This primer is an airtight chamber with a screw cap. Because it is permanently higher than the carburettor, the engine starts no problem. My unit is several years old and when preparing to undertake this mod I discovered that all fuel hoses (rubber) were perished and leaking so they also required replacing.

What a wonderful chance to understand the bigger issues , as explained by a man I now recognize is not only a national treasure, but a world resource : Rob Sherwood. I got here because I wanted to set up the best weak signal 2m station I could with modest financial resources. The more I combed the specs for available transceivers, the more tweedle dee-tweedle dum I encountered over a 25-30 year span. Lots of new packages, and whistling bells, but no more meat on the plate came with the BIG price increases. Nothing explains why better than this video. As we look back now on the utter crap once sold to us ( horrid synthesizer phase noise) we will surely look back on these stagnated receivers and filthy PAs and wonder why so few stood up and squwaked. Bravo ! de W6WUH

I would love to see a video measuring the actual output from the the stator, voltage, frequency, how many phases etc.

Can you please send me a photo of the ignition coil and current amplifier in situ?

I love this little generator. So easy to use

Mr Richardson if you are reading this its Beau from Burnt Oak Primary School in Gillingham I have really been missing you since I left year 6 I hope you still remember Alder Class if you do see this I will be very happy do you remember What's The Crime Mr Wolf - Kind Regards Beau Whiting

Really interesting! Watched all of it, thanks for the upload!

When we were apprentices we all got meggered

I'm trying to pair UV-3R+ with the old Motorollas of my co-workers. I found the frequency and I can hear them, but when I transmit, their walkie-talkies are only flashing LED, without receiving my voice. What can i do?

What you up these days? Missing more of these presentations for HAMmers

Great Video! Thank You!

*100% best **Generater.Systems** I have used. A test for hurricane prep here in Louisiana: three AC units, 5000, 5000 & 8000, 3 fridges, 2 device power setups, 4 flat screens....AND I had 40% of the power meter to spare.*

Thanks

There's now going to be an awful lot of people who's situation means they are unable to ensure the public don't get close to their antenna - users living in flats and bungalows for example. Are they expected to give up their hobby?

good job.......... 👏👍

How much QRM does it make on HF bands? I bought one today as my old friend went SK and his widow is selling away radio gear. Cheerio.

Hell of a noise. Can't hear what you're saying. Please put subtitles on the video. Thank you.

Hey I have a uv-3r+ and It dose not have the 2.5khz step the lowest it gose is to 5khz do you know if there's a fix for this because I can't go to Certain frequencies

It`s a pity they don`t reply to e-mails. It's polite if nothing else.

The trick is not to just try and minimise your separation distances, but to perform calculations for the worse case scenarios. That way you can know your maximum operating EMF. As for proving that you don't use 100w to Mr OFCOM when he turns up at your door, they can't prove that Foundation licensees are operating at 10w with their 100w capable radio. I have a linear in my shack, but I never use it.. Mr OFCOM will have to take my word for it (It's not wired up anyway). so there is a matter of common sense to be used here.. This is not an exercise in absolutes. The aim of OFCOM is for people to pay attention to their EMF fields and to ensure that you mitigate risk against exposure to the public. Enforcement is going to be an issue for OFCOM, but if their attention is drawn to your installation and they turn up to inspect it, you will need to be able to demonstrate you have performed an assessment and have some documentary evidence. If you think you can get away with doing nothing, it is a bit like driving your car without an MOT.. are you going to risk it? Obviously nothing happens until you get caught, but the risk is always there. The RSGB calculator also has a 'boresite' option which allows you to input an attenuation level based on the transmission plain of an aerial.(The transmission lobe tends to be at the end of the aerial and there is a reduced EMF below that). It provides a more accurate assessment of Horzontal Yagi's. You can also calculate the gain of your own aerial and input that as a custom figure, however, if you have a doublet bent around the garden, modelling will note help you, you might as well just use the figures for a dipole. Plan for the worst, know your limitations and document what you do to operate with in the limitations, and you should be good to go!

Good presentation Leslie. Very useful in simplifying it and dispelling the fears many have about doing this. Have copied the link to my local clubs forum (Felixstowe & District A.R.S.) which is a useful addition to the training presentation our local Raynet training officer and club member did for us.

Nice presentation Les. Thanks for all the work you put into it.

In 2020, Lidl sold the PGI 1200 A1 generator - slightly different visual than the one in this video. I’ll have to research what the difference was??? My question was regarding the earth connection on the generator....when would you need to use that?

Many thanks for sometihng interesting on a "boring TV" night in New Zealand! Allan ZL1CO

Thanks Chris. I bought the similar one today £79 !!!!

I still use mine daily. I purchased in 2016. I like the UV-3r because I can remove the USB cable from wall charger and charge the transceiver in my truck or in the field via a solar charger or battery bank. These are solid little radio's. I use a 15 inch MFJ sma male antenna on mine.

Merhaba. 1 ve 2 kanalı aynı anda nasıl dinleyebilirim. Motorola cp40 da bu özellik var. Baofeng 3r de bu özellik varmı

too bad no relative comparisons to 991a are made

THIS IS EARRAPE

Very Interesting, Thanks for sharing Chris

За кратки разстояния е добро радио. Може да се смени фабричната антена с по- добра.

Best DX 73

Благодаря

Добро радио за парите си.

Theres also a dw (duel watch) setting.

VERY interesting talk. Thanks for sharing. I've been telling everyone who'll listen for ages that a 1KW amp with a P1dB of 1050W is NOT a 1KW amp. the clue is in the name of the P1dB measurement!

Is there a filter that will filter out contests? Who cares is dynamic range is 97 DB or 105 DB, as if someone can tell the difference.

Great presentation. Are these slide available?

I purchased one of these for power outages we have during storms and the generator is definitely not without problems. The noise level is abhorrent which can be heard from the video. A MUCH bigger problem is using the generator with devices that suck an awful lot of amperes when plugged in. This is called "inrush current". My 125W Whirlpool freezer either stops the generator or refuses to start (due to voltage drop for a few hundred milliseconds). What I have had to do is do a "hill start" with the fridge plugging it in before starting the generator. The generator starts with a bit of a cough but in most cases, the freezer starts and the generator keeps running. The freezer taking 10% of what the generator has to offer (1200W) you would think that you can plug in a laptop power supply (60W). Those devices, however, have a tendency to power up taking a huge inrush current as well (quite a surprise). So do the same you did with the fridge (the "jump-start"). Why the laptop power supply works like this may be due to some capacitor loading or some phenomenon with the transformer circuitry. The compressors in cheap/mid-price/old freezers and fridges are piston based (like Watt's steam engine) and getting them run the first stroke requires a lot more power than keeping them running. Some do have a "soft start" but I have not seen one so far. So if you are planning to buy a generator to run a freezer or a fridge you should consider purchasing a more powerful alternative. Anyhow, both of the problems I described are very common and you will find lots of discussions by Googling "inrush current inverter", for example.

it's a neat idea. I love it. I need one in my bathroom.
