If you use a carrier from AM or CW you wouldn’t have to say RRRRRRf 😂

"Bode plots" are mentioned a few times in this video, pronounced with a silent 'e'. However, the correct pronunciation is the way their inventor, Hendrik Bode, said his name, as "boh-dee".

Good video ty

In Germany, the switched off about all of the MW radio stations some years ago. Was that the case in the UK, too? Maybe it worked better back in the 70s just because of a more comprehensive set of radio stations?

I seem to remember being pleased with mine, the kit spent most of its time with this circuit. But likewise, it did work better after dark too.

Really enjoyed watching today's video. A three transistor radio that I built back in the day was from the take 20 series number 9. Really worked well. It used three BC169 transistors with good volume. Cheers Bill.

Bill, I don’t understand how you managed to misspell that companies’ name, but you managed. The company in Holland that it’s products are known in America (and possibly elsewhere) as “Norelco” has, but one “L” in it. They now sell many products under the Philips name also.

My parents gave me this brand new kit as a boy and I built many of the projects. They all worked flawlessly. This MW radio impressed me the most as it worked so well. I remember being very unhappy that I had to take it apart to make something else. My version of the kit was totally original and came from Philips in the Netherlands. It appears as if there is more than one version of the kit, which may explain the disparity in the results.

I remember doing that circuit and being able to receive MW radio quite well. What surprises me is that my Philips EE kit was from '71 and the transistors were all PNP germanium (two AC126 and one AF116), not silicon as in yours from '69 which is quite odd. Also the diode was a germanium OA90. It seems to me quite strange that an older kit sports newer technology than what was in mine...

Yes I had this set too and the two extension kits as well. I remember making that radio and yes it didn't work. I spent my whole life in electrics and antenna design. I'm now 68 and retired. But I'm still at it. Best 73 Paul G0MIH, HS0ZLQ.

On the 2D72 the software update time is inexcusable! Even after upgrading to the latest firmware using Hantek's DfuSe tool. The software will crash under some Time/Div settings. Absolutely horrible. Too bad I bought it years ago, so its impossible to return, lol

Thank u.

Great review sir! I already purchased 2 of these due to the good reviews and simplicity for my lower level HVAC/R service technicians, I still use my fluke 378FC that I have used for years. The Kaiweets multimeters look good and work well too. I have not been able to get/find support for my Kaiweets 602 meters I just purchased and brings it to why I have reached out to you, I am looking for A magnetic mount for this meter?? It looks like Kaiweets is A big up to date meter manufacturer so they must have one available or can at least suggest one that works with their products. Any pointers would be greatly appreciated, Thanks in Advance, Andy's Heating & Refrigeration.

SO, how much level does it need to work as a frequency counter??? I couldn't get it to read the oscillator in 2 short wave radios.Probably not enough level. It was about a $5 kit on Ebay here. Thanks.

Thank you very much. You made my day..!🙂

I paid $60 with one extra probe from Chinese taobao site. You can't beat its price. Years ago, a 50Mhz probe cost more than $100!

Great video! Thanks! Any recommendations on how to create the negative supply rail?

Finally, I've found a video that explains CLEARLY the basics of how to use this!!! Well done, you've helped one oscilloscope noob at least :-)

A very interesting video again Bill. Looking forward to the next part. Many thanks.

I haven't purchased one of these FY6900 units yet, but I am VERY close. Some interesting ideas for doing frequency sweeps for filter and Bode plot measurements. The FM modulation idea from fredsmith5473 looks promising. I was wondering about another idea... Let's say you set up a sweep on channel 1, for 10kHz to 100kHz, with a sweep rate of once per second. Then, on channel 2, you set up a square wave, with 1 Hz frequency. If you display both on a scope (triggering on the square wave), how will they appear relative to each each other? Will they drift relative to one another? Will they stay locked? Will the edges of the square wave be at some arbitrary position relative to the channel 1 frequency-sweep? If they drift, could you very slightly adjust the 1Hz square wave frequency so that the two waveforms stay in more-or-less sync? (Kind of like manually adjusting the time base on an old scope with no trigger. :-) )

I was also given a Philips EE kit in the late 60's. It was a probably earlier version of yours, with PNP Ge transistors (2 x AC126 + 1 x AF116), it didn't have wings or panel and different box (blue colour) and manuals. The spring mechanism was exactly the same. I was 13yrs old & now 70 and have been in electronics since that day, from crystal sets to rcommercial radio & TV transmitters. Thank you for sharing this with us, great memories right there ! Cheers, Baz from Oz

it seems that your CH1 probe is not compensated as it should...

Wow...what a good "cleaning job" the S. Trigger is doing. Amazing.

Thanks for sharing your knowlege mate! Your videos are really helpful. Greetings from mexico

Just found this channel about a week ago, I'm a software guy trying to learn about hardware, good stuff here!

This helped me a lot. Thank you! 👍

Thank you for such didactic explanation ! I am missing four features on the 703: 1) A BNC output for the fctn gen 2) The thermometer 3) CAT rating for the BNC inputs 4) The second osciloscope probe

Great job. Thanks for sharing! N6WHV

Thank you for this brilliant demonstration of the usefulness of such equipment, which will enable beginners to put calibrated images on their basic experiments of course. 73

Excellent presentation. Thanks N6WHV

my problem is the device is recognized its on my computer screen everything is fine but when I put it in dfu mode it disconnects from the computer and says no device found I put it in regular mode it connects again has anyone had this problem or did I get a pos?

Those oldie worldie dark brown resistors just bring back wave upon wave of nostalgia. In the early 1980s, I used to get most of my components from taking old tellies to bits... and I had plenty of those resistors "in stock". Little lick of dark brown paint and that replacement transistor will look FINE.

which is more accurate when measuring ac and dc current?

Those RF Demo Kits are a really handy learning tool but those tiny UFL connectors.......... Imsai Guy has designed one with SMA connectors. I think the PCB for it is on his share site at PCB Way. Good vid Bill, thanks.

Just built this rig and am amazed at its performance. Having said that, I had a friend with good ears listen to my transmissions, and without having seen your video, he said that it sounded scooped in the upper mid-range. Exactly what your spectrum analyzer shows! Time to find a new mic. Keep up the great work!

Thanks for this Bill, very enjoyable and informative. Looking forward to part 2. BTW I didn't get notification for your newest videos even though I've clicked on the bell.

I had Rodwins Toy Store (Southgate) for spares nearish to me. But I also had a "proper" Electronics shop in Edmonton, also north London. I got my EE kit (I'm sure it was also the 1003) Christmas 1973, I was 12. I did end up in the industry and still am. So it must have done some good. Thanks for sharing.

What is the difference between this and the HT118E?

I remember getting this kit as a Christmas present back in 1968 when I was 12 years old, this started me off in my love of Electronics and a career as a TV Radio Engineer, and later as an Offshore Electronics Technician in the oil & gas Industry. Sadly I no longer have the kit, but still still have the BC148 & BF194 transistors in my workshop.

The Philips boxes with electronic parts in it for the young electronic engineers are put together by well qualified engineers who loved their work and enjoyed to inspire the young and the old. I had one of these boxes and it was great! It feels like it was only last week, not fifty plus years ago. This present brought me more joy and excitement then the sportwagon I got many years after this. I have had a wonderful childhood, two loving parents, a safe, pleasant and clean surrounding (The Netherlands) Wouldn't it be nice if we would ask Royal Philips to restart these Philips construction boxes all over again, renew this wonderful journey full of discoveries and excitement. Nowadays too many children grow up confused in a hateful place with wars and exploitment of sadness.

I remember someone having one of these or similar when I was at Tech High School circa 1964 - 65. But that was, if I recall, OC71, OC72, OC44 types. Maybe even AF115's. Scrape the paint of an OC71 and you got yourself a light detector, maybe.

I had one of those in the 80's . nice memory, I almost forget about this game but I remember quickly the strange shape of the springs :)

Thank you !!!!!!

I also in around 1970 had the Mechanical version, I assume because my father was a mechanical eng, but I still went into electronics, I did get one of those kits where you could build lots of circuits something like 150 in one but I can't find a picture of the one I had.

What a great old kit. Thanks for showing it.

Not correct measurment, 10Vpp = 3,53Vrms because double Veff in sine wave ,one Veff = Vp/square root 2 In you video must be 20Vpp to Vrms = 7,07V That generator basically generates the amplitude in Vp In house outlet 230Vrms = 325Veff = 650Vpp

Very nice. I use a network analyser for my antenna work but it's a good project.

That's brilliant. I had the same kit loved it. I'm now 68 and would love to go back in time and get one. I had three of these the other where up grade kits. Best 73 Paul G0MIH and HS0ZLQ.
