Hi
I am looking to amp my 1w FM transmitter to 40w+, i want to use the pcb from pcs and also the digram but its a bit unclear. I would be greaful if someone could give me a component list and a modded diagram to show where they go.
Thanks

You'll have to improvise a little.
Its a fairly simple diagram and it is not strictly
important where certain component goes on the PCB, but make
sure you stick to the diagram.
Think of it as a breadboard for RF amps. Handy to keep around
for testing RF amps and transistors.

Thanks for the reply.
Do you have a component list? I dont understand what components
are used... whats 4/20p??? or 10p??? 270 4/2W???
A component list would really help.
Thanks.

I fear you do not know enough about the basicy for this circuit.

I have built transmitters, stereo encoders, chipped ps2's and xbox's - i dont need to understand what each component does...i just need to follow some proper instructions.
thanks for the reply tho

If you don't know that 10p means 10pF you obviously
don't have much experience, if any.
4/20 is a trimmer, 4-20pF.

If 10p means 10pF then why not put 10pf on the diagram? I have quite a bit of experience in building circuits as i can read and follow instructions.
The digram on the site only gives very vague idea.
However, bearing in mind what you have said i will have a go at building the amp and let you know what happens.
Thanks for the reply
BTW 10p = £0.10 where i come from

Why not put 10 pence in there than and see what happens?

i tried that the first time and found that a 20p worked better

i thought that after all the trouble i had getting the rds to work you would be a bit more helpful and forecoming with the information - i can i was wrong
btw - its still working brilliant!

Let me know if you have any more problems.
I think we're clear for now, no?
Have fun!
