You need what is called a "Sqelch circuit", in between the audio output and the speaker.
link below, just search for FM radio squelch circuits.

Re: AD9850 output issue using SPI
I used a couple of similar boards a few years ago to make a VFO using 2 boards with one 90 degrees out of phase with the other, just use one xtal from 1 board for both oputs so they were in sync, make sure that D0 and D1 are pulled high on the board and D2 pulled low, esential for serial mode operat...

Re: AD9833 Waveform Click board compatibility with 28pin chi
Yup, do agree with you on that, tis a bit strange.Its just that is odd that Mikroe would make a Click board that restrict the chip that can be used with. It can be easily be used with other smaller chips like the 28 or 20 pins ones.

Re: AD9833 Waveform Click board compatibility with 28pin chi
No what you could do, is say use RA0 and RA1 on your 28pin pic (or any two unsed pins) for the RST and CS then just use jumper link wires from RA1 and RA0 to RE0 and RE1 pins on the port headers at the side of the V7 board, just make sure that you don't have a 40 pin pic in the board and that Ra0 an...

Re: Strange Behaviour PIC18F25K40
I have read about Silicon Errata and mikroc compiler bug with k40 device, so is this the case? The silicon errata document that Microchip produces for each range of device or family of devices will list the embedded PIC ID that it relates to, so if you have your debugger connected to your board wit...

Re: Unable to program - No error
It might be worth while disabling any modules that uses pins you are using for the LCD, using the PMD regs. Had that issue before.

Re: Can program but can't debug
Just a side note on this Filip and Bicycle, I have found that under windows 10 unless you install all the software (compiler, programmer software etc) as administrator or 'run as administrator' when installting the software it won't work. Am afraid i have found win 10 to be very annoying for this an...

Re: PWM not working properly on 18F4550
Ok correct me if I'm wrong but don't you still need a while/do-while loop in main func??? For other compilers the answer is yes. For mikroC the infinite loop at end is optional, since the compiler adds it anyway. Good practice to put it there, as it makes it explicit and portable. Makes debugging a...

Re: How do you open and read *.mpkg files in Window 10 ?
Someone will correct me if i'm wrong...the SPI3_Init_Advanced function is part of the Mikro C inbuilt library so won't show in the C file but you should find it in the listing if you open up the list file in the IDE, I could be wrong.

Download and install this
https://www.mikroe.com/package-manager
You will then be able to open and install the mp3 click library into the Mikroc C IDE, you can also make your own mpkg packages for a piece of hardware that interfaces with a MCU and share it with others.
