Tolong ajari saya mengenai konsep pemancar yg menggunakan PLL, dan bagaimana cara membuat PLL secara umum !
ide1
You have measurement test such as
1). Frequency counter.
2). Low power dummy load (you can made paralel resistor), see my link on Nice Link and follow it.
3). Vswr Meter.
4). Better you able to used computer, download program pcb design such as sprint lay out (U need to pay) but U can get
the software as free with do unlock the program with PATCH.....also see my subject on this forum......or U just
type on browser "sprintlayout .torrent".
5). There is two thing, first what kind U went to made
1). Use PIC IC such as 16F84 or 16F870 etc.....U can written with basic language - C - Assembler or
or just copy and paste HEX file to the software, many software on internet as free and but need to purchase.
2). oR MC145151 or 52 Motorolla, if U use this so no need to make program.
6). Before U assembly the exciter I called, U do first install all part Oscillator.....follow your counter what happen U see frequency or
not, ensure U have any number are FM frequency on counter display.
7). Done oscillator, now you install all part PLL (phase locked loop), check and measure with counter U have frequency at point test
I don't know exactly what kind schematic as U plan to building.
. Next step, install all stage driver and final, don't forget U have already Install VSWR meter at Output of power amplifier.
9). Ensure all soldering has good and right place and not shorted to other pad layer hole or something make system broken or
burned.
10). This is very important, U have Money to purchase parts and measurement test as you need.
11). U have problem, so do not hesitate to contact me Oneng OON.
Cheers mate, hope U have follow my step so U can build and have own FM Exciter Transmitter as a hobbies.
Hobbies is expensive but with hobbies U have Money for the future.
