Minimalist DSP V3.0 Released - Shared Project Here

Firmware update 3.0 of my Si4735/32 Minimalist Receiver project has been released. The receiver software has undergone several improvements, bug fixes, unnecessary functions have been removed and new functions have been added to make it simpler and easier to use, focusing on the main thing: listening to the radio.
Here is a demonstration of the radio receiver's performance, using a 7-meter indoor wire antenna.
Below are the links to download the firmware V 3.0 and project documentations / instructions.

A wonderful small but powerful radio. Congratulations

Hello Mirko, thank you!

[@gheorgheberlogea9735]

Hello, I'm glad you shared the construction data, congratulations for the work done. I'll try to build it to see if it works for me in Romania. Many thanks once again.

Hello Stefano, thank you!

[@renatoalves2282]

Acabei de atualizar para versão 3.0 ficou muito bom, bem mais leve, prático e funcional. Obrigado Júlio. Renato PU2RAS.

Good project. I was going to do version 2.7, but I'm already doing 3.0. I have a question - is it possible to write a hex file to the firmware with XLoader?

[@Cesarsound1]

Hello Algirdas. Maybe it will work, but I haven't tested it with Xloader, I've only been using AVRDUDESS + USBASP. Thanks!

[@algirdasmickevicius6406]

@@Cesarsound1 Yes, today 02.07) I managed to write firmware with USBasp ISP! Good picture!

[@alfguimaraes]

Excelente projeto obrigado por ter compartilhado os arquivos, estou esperando o programador chegar da China para finalizar minha montagem. Muito obrigado!

Hello adiis, thank you!

[@digitalmediafan]

Nice but FM signals on 80, 84 AND 86 Mhz ?? Where are you located ?

[@Cesarsound1]

Hello, I am from Brazil. Here we have the extended FM band, which starts at 76MHz up to 88MHz, this band was reserved for Medium Wave stations that are being closed and migrating to FM here in the country. Thank you!

[@johnc3403]

@@Cesarsound1 That's interesting. How easy is it to buy an FM receiver that receives below 87 MHz? I think I saw one here in Europe many years ago but didn't understand what I was looking at.

[@Cesarsound1]

@johnc3403 On Aliexpress / eBay / Amazon you can find FM radio receivers with this extended range. To name a few there are Tecsun PL-330, PL-880, XHDATA D-808.

[@digitalmediafan]

@johnc3403 yes many many radios exsist with 64 - 108 Mhz or old FM tuners made for Japan covering 76 - 108 Mhz

Hello cotton, thank you!

[@cotton9164]

@Cesarsound1 У вас интересные конструкции радио. Спасибо!!!

[@studytechhindi3995]

I have almost made this but my LCR meter fails to measure the air core inductor of L3- 150nH and L4- 300nH, can you please tell me what is the turn ratio for this two inductor?

[@Cesarsound1]

Hello study, the inductors: L4 = 15 turns of 0.8mm enameled copper wire, L3 = 10 turns of 0.8mm enameled copper wire wound in a 4mm circular shape. It is recommended to buy L5 ready-made, it is a commercial component. The inductors L1 and L2 are ferrite bead, also commercial components. The recommended AM antenna is the traditional circular ferrite bar with a diameter of 10mm, length 12cm and a 300uH coil, which is a commercial component. To build the inductors at home it is recommended to have an inductance meter (LC meter). Thank you!

9KHz step for EU?

[@Cesarsound1]

Yes.
