What circuit are you building ?

That photo comes up as a postage stamp for me.

That is telling you your control Pot connections on B

A is showing speaker and switch connections.

A i understand but B is my problem with all the wires crossing over i just dont understand how to conect them.and i dont understand what the wiring on the diagram stands for
i guess what i need is someone to tell me how to make these connections

The wires that cross over are not connected but have to be shown for clarity in the circuit. Paper and the computer screen are two dimensional and the crossing over represents the third dimension of one wire passing over another in the real circuit. What you have on B is a series of potentiometers or variable resisters (different name for the same item) that are used to adjust the detector. In B they are shown as being wired to a connector. Some people wire them direct rather than via connector. If you do that, give them about an inch of extra wire to help later when you assemble the unit into its case.

The black dots indicate that the potentiometers are hard wired at that point to the same point. Probably either ground or power. I didn't look at the pin definitions that closely.

Go here for a short tutorial on schematics:

Hello NC DD . On figure B connections 6 through 12 shows two 25k potentiometers and the battey hook-up . Connections 2 through 5 shows three potentiometers with pins 4 and 5 adjusting your transmit power or [pulse on time] . Connections 3 to 4 is the signal or frequency adjust . And pins 2 to 4 adjust noise but I need to see the schematic because I question the common connection made on pin number 4 . What schematic are you using ? Then we can answer you correctly .
Regards..............Eugene

thank you golddigger.the mainproblem is where, 5 cross's over to 2 but it intersects at wire 4 do it make a connection with 4
thank you eugene this was a kit i bought from a guy in Bulgaria the board was already assembaled. i have to make all the conections make a coil power up then test.i had asked awhile back your opinion on this kit.

Pin 5 to center pole of 10k pot.

10k pot end pole to pin 4 and center pole of 220k pot.

center of 220k pot to pin 2


Pin 3 to center pole of 47k pot

47k pot end pole to pin 4 that is also connected to 220 pot.

First of all, 5 never crosses to 2. Pin 5 goes to the wiper (usually the center pin) of the 10k potentiometer. One of the other pins on the pot (abbreviation for potentiometer) is wired so the that common point that gets connected to pin 4. What happens is that all the wires are soldered or crimped together into the connector for pin 4.

The arrow on those diagrams indicates the wiper on the pot. That is the internal part of the pot that moves across the circular bit of carbon inside the pot. You can't see the wiper but you have to know what it does to fully understand the workings of what you are doing. The fact is that if you wire the wrong leads on the pot, the circuit can be damaged so you are very wise to ask about it before doing it.

Pots normally have three pins on them but some kit providers cut the extras off so as not to confuse the builder. Imagine if you were to hook up the correct center pin, the internal part that moves, and the wrong outer pin. It would be harmless as far as damaging the circuit but it would mean that your control knob works backwards. When you think you are increasing volume, for example, it would lower instead. I hope you get the idea. For the real techies out there, please don't mind the simplicity of my instructions here.
