My Project List

Here's my AIO Project in Action Click Here or see the video on youtube Click Here

Need component for your project? please visit my store www.rf-modules.com. All products/components in this website is in stock, i will deleted it if not available/out off stock. I will shipp in same day.


Available our blue print design:
1. ALL IN ONE EXCITER Design Completed Design with HEX Code
2. FM AMPLIFIER MODULE 150 WATTS Completed Design
3. FM AMPLIFIER MODULE 300 WATTS Completed Design
4. FM AMPLIFIER PALLET 300 Watts Completed Design
5. FM 1 WATT PLL EXCITER PLUS Completed Design with HEX Code

1. FM PLL Transmitter Max Pro 1
This is FM PLL Transmitter with freq 88-108 Mhz range, You can download all tools to build it. The microcontroller is PIC16F628A.
It's use three buttons to change and set the menu, here's the menu display

This is startup display, will count until 100%

First display you can see freq in Mhz and lock condition

Press menu and up/down to change step size, can change from 50,100, 150, 200, 250 ....... 1000 Khz

Set lower limit, press menu 2 times and up/down to change the limit. I test with lower frequency to 84 Mhz and it abble to lock without any change to oscillator coil.

Set high limit, press menu 3 times and up/down to change the limit. I test with higher frequency to 112 Mhz and it abble to lock without any change to oscillator coil.

To see pll status (lock and unlocked condition), press menu 4 times

In Action can Lock in 117.90 Mhz with no problem

What i'm offer for this project?

I'm offer for best price for one pcs pcb + one pcs TSA5511 for US $ 12(Out Off Stock). For other components for this project, please buy directly from my store at www.henryelectronics.com
If you want buy PIC16F628A for this project, i can pre-programmed with hex code for free.

Any question please drop your email [email protected], i will happy to answer it. Or give me a call at +62-765-7018201

2. FM AMPLIFIER 150 WATTS / BW AMPLIFIER 150 WATTS based SD1407 Transistor

This amplifier is design by Broadcast Warehouse, i redraw schematic and redesign the pcb, hope you happy with it and please send me the photo if you have to build it.

Here's the photo was sent by Derrick from London, He was built the amplifier

Please right click to save as to your local drive, if you have problem to display pdf format on your browser

3. FM Stereo PLL Transmitter Based BH1415F IC

This is FM PLL Stereo based BH1415F IC from Rohm, it's has built in PLL and Stereo Encoder. You can download the schematic, pcb layout and Hex code. The menu on display is look like for MaxPro 1, the different is this have step 100Khz, 200Khz,.....1000Khz and have Mode menu (stereo/mono).

In Action, LCD Display can solder directly on the bottom
