 I just want to make a quick video of this, what I've done is I've swapped out my 2 minute aerial and I've put in this particular, now I don't know the length of this, I can imagine it's quite long, but for the AM reception I understand that you need quite a long antenna anyway, but you can coil it up and that's what's happened here, you've got a long length of wire on here and we do get a better reception. Now, this variable capacitor is, I think it's from about 2.7 pico to 406 pico. I think that's wider, that's more capacitance variation that's needed for the AM frequency, the general AM frequency that's picked up. I don't know that 100%, I just saw that on a lot of these other variable capacitors, they don't have as much capacitance. I did see somewhere on the internet that somebody said they got 100nF, but I don't think they've put that down correctly, I think they got pico farad. That's a lot of capacitance. Anyway, so, perfectly quiet system, it's all on and down at this end I don't normally get anything when the capacitor is all the way to the other side in this, but I get a few stations. In this end I don't normally get anything, but do you remember this? That's right, I haven't put the wire off it yet because I thought I might use it for this, for that one, but I forgot when I was doing it. But this is a ferrite core and if I put this in here and just put it partially in, I get a station that I wouldn't get without it. Because if I take that out, this thing is a carbon rod. I've got two of these and I made a magnesium type, you know, air battery. Even if I put this in, I can't get that other station. There's something just there, but I take my hands away and it goes. And if I pop this in, I'll put this ferrite in and there we go. So there's an extra station that I don't normally have without that. Just for to do this, that's all the way down to the bottom part. And if I turn the volume up a little bit more, so we don't miss anything. I'll pretty slowly just go through this range on the capacitor. I thought I heard something there. I can definitely hear something there, but I'm just going to kind of go without it first. Incredible, so a huge gap there between the scale of the abuse reported and the action schools are taking in response. Let's bring back Dr. Carleen Fermin from the University of Bedfordshire, Carleen. You were nodding away, but really trying to put pressure on him whereby maybe eventually you'll take his place because we, you know, it feels like we'll get everything on the shot. We have no idea what that's going to be. I'm not going to say this is going to happen in everything, but gigs, you know, TV, that don't replace anything, so practically everything, really. Do you think so? Um, I, I hate to listen to a strong enough word. I know he's a lovely man. I guess I'm very worried about something. Oh, sorry. Anyway. There we go. A bit longer length on the aerial and that certainly makes a difference in cruise radio station reception. Playing around with a bit of ferrite core. Maybe if I took the wire off, I'd have a different effect. I think I'll do that in a bit. Probably won't make a video of it. There we go. Such a simple little AM receiver. That's all there is to it. And of course then just bump it up with amplification but you don't need to do that really. You can put a little head front on this and hear something. There you go. Thanks for watching.
