The whole recording in text, the same words Hertz answers from, so what you can watch you can also search and ask about.
0:00um if it's especially wet, you can sometimes just pull it out and just stick it on the on the floor. You guys still there? So, that's how we can put a signal onto a onto a house service. And the other good thing that we can do with this is there's a few little tricks we can do um with a with a cat 4, which I like. You remember we talked about it being dual frequency and when it's turned up quite high, you'll hear the hear the two frequencies and stuff. So, let me just show you what I'm doing here. I've I've basically got the house here.
0:33Yeah. With the service coming out and then the LV main like this. So, I've got 100% I've connected onto here. By the way, I've got 100% here and then 50/50. And when when you have this, you get quite a unique thing that happens on the joint. And I'm going to show you. So on the video, this works with with with most locators as well, guys. Um, so on the video, I am now locating the LV main. So just to be clear, guys, if you look at my drawing, I'm here at the moment. Yeah. Pacing that way. I'm going to find the LV main. And once I found it, I'm going
1:09to turn the sensitivity control up until I can hear both frequencies coming through as a little reference point. So you'll see now I'm going to crank that ride up using the manual again, hear the change in tone, stop turning, walk forward. The signal will drop to zero. When I carry on walking, it will come back up. I will now reverse. And that point there where it drops to zero is the joint. I turn the other way. Now that is the house surface. Okay. So that's a neat little trick you can do. Of course guys, you remember with this that obviously when we're doing this training normally we do the theory and
1:48then we go and do the practical outside. So we kind of show people the theory and science behind it and then we go out and practice it. I can't do that with you guys. You'll have to go out and practice on your own and see if you can see if you can have a go with these techniques. You you you might remember mentioned before about the again the dual frequency coming from this transmitter. The 131 is really cool. There's some really cool little tricks we can do with it. Um, again, not got loads of time to go into massive amounts of detail, but with 131, we can make it jump gaps. We
