    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?

    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.

  • @pisotones2348
    @pisotones2348 11 дней назад

    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...

    • @Moonlight0551
      @Moonlight0551 3 дня назад

      Mine was the same from memory(in Australia) The AF116 maybe a 119 had four leads and the leads were prone to break easily. I think the extra lead was a screen. Would have been in 66 - 67 I think. The 3 transistor design worked OK but I lived in the country and we only had two stations to choose from.

  • @paulswift700

    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.

    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. :-) )

    • @erikdenhouter
      @erikdenhouter 20 дней назад

      The 1 Hz sweep rate and the 1Hz square wave are never the same coming out of ch1 and ch2. But you can adjust the frequency of ch2 in the 1/1000 of a Hz, so after an hour of tedious setting and resetting you could get an image that 'sort of' locks. The most important problem I encountered sweeping with the internal sweep + a ramp signal from ch2 connected to the scope in X-Y mode (I tried a day's work to test, haven't tried the VCO yet) is that the frequency is not raised analogue, but in about 10-20 steps from low to high. On fast sweep speeds, say more than 1/20 of a second, a filter that is swept will show a stair case pattern, and only a very few steps. Unusable. You could sweep slower, then there are more steps per curve, but since I have an analogue scope it gets very hard to judge what I see. With a digital storage scope you are better off. You can look at his other video to see an example of that: ruclips.net/video/yrS-1KXppmw/видео.html&lc=UgwPSD-weP_YRG4OJRp4AaABAg.A4MDxKwW9rtA4UAaIDZlLD Next test I will try the VCO with the ramp from CH2, but I assume that that will make no difference, otherwise it would be a feature already.

    • @erikdenhouter
      @erikdenhouter 19 дней назад

      Update: I just setup a sweep through the VCO input with a ramp from CH2, and had succes. No more bulky steps like from the internal sweep function, but a smooth path, and fast enough that my analoge scope shows a workable image of a pass through filter, so no digital storage scope needed. Just follow the instructions in that other video. Internal sweep, according to the manual, the frequency steps used when sweeping lineair are defined by: Step value =(End value - Start value)/(Sweep time*100) So if you want a nice image, and need for that 20 images/sec on your (analoge) scope screen, and you sweep an IF filter from 535kHz - 575kHz, the steps the sweeper uses are (575 - 535) / (0.05*100) = 8kHz steps..... That is what I meant by unusable.

  • @techobaz55

    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

    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.
