Hi don't no if am posting in the right place but can some one help please

Am lookinG in to make an Am transmitter but have bin given a list of parts

resistor - 12r
resistor - 330k
capacitor - 224m
capacitor - 472
transistor - bc182lb
And ferret rod
But have some one got a diagram please or some help thanks

hi there,
welcome to EP

Well it would be better to find a circuit for one then you will know what parts you need

Try googling basic AM transmitter circuit diagram and see what you come up with

Just stick all the parts together and join them to the ferret rod. That's the we all work in electronics.

And be sure to use genuine ferret glue, not that gorilla glue stuff because it expands and makes a mess.

And a new proverb is born:

"Never use Gorilla glue when Ferret glue will do."

Also, "Never bring a ferret (glued or not) to a gunfight; bring a Gorilla and/or a gun." Elmer Keith would (probably) say that if he were still alive.

Good evening all how do I work out how many turns I put on the ferrite rod to get the right mhz please

This isn't easy since you know absolutely NOTHING about the magnetic characteristics of the ferrite rod, nor have you specified a variable tuning capacitor that you would use to resonate the "right mhz" unless your post of "capacitor - 472" refers to a 472 pF air-variable capacitor. If you can, take a look at a typical "loop stick" antenna inside a portable AM radio to get some idea of the number of turns and the wire gauge you need to use. Often Litz wire is used for this application, which you probably won't be able to find. You can purchase pre-wound ferrite rods with sufficient turns for broadcast AM reception. See this Google page for more information.
