I got a few circiuts from

Re: Pls help

Hi,
the biggest difficulty of those schematics is, that in most cases you are not able to get all the parts you need...
Kleiner Onkel´s circuit is easier to build and the parts are more common...

Often you have to collect different appropriate parts, as much as possible, and combine them to a new circuit .
Therefore, you need much skill and patience...

In your case, to see if you would be able to manage this, first try to get the following parts:

1. VCO (Voltage Controlled Oscillator). For example:
POS1060 from Minicircuits (easy to handle) or
MAX2623 from Maxim/Dallas (SMD circuit, PBC is needed!)
Sure, other vco will work, too. But i don´t know where to buy them.
(Any vco circuit with 900-1000MHz is possible.)

2. Many old(!) mobile phones. From those you can get appropriative output amplifiers.

Thank you very much man.


But where can I find out the "Kleiner Onkel´s circuit".

Hi...


Don't try this project if you're not really concerned with electronic circuits
and RF equipment.
