- This video shows the SI4730-D60 working on LW, MW and SW. Also, the FM/RDS feature works well.
ATTENTION: The author of this video does not encourage anyone to buy the SI4730 for the purpose of listening to stations on LW and SW. If you really want to build a LW and SW receiver based on SI473X family, please aquire the Si4732, Si4734 or SI4735 devices.

1. [PU2CLR Si4735 Library for Arduino](pu2clr.github..... This library was built based on “Si47XX PROGRAMMING GUIDE; AN332” and it has support to FM, AM and SSB modes (LW, MW and SW). It also can be used on all members of the SI47XX family respecting, of course, the features available for each IC version;
2. [PU2CLR SI4844 Arduino Library](github.com/pu2.... This is an Arduino library for the SI4844, BROADCAST ANALOG TUNING DIGITAL DISPLAY AM/FM/SW RADIO RECEIVER, IC from Silicon Labs. It is available on Arduino IDE. This library is intended to provide an easier interface for controlling the SI4844.
3. [PU2CLR AKC695X Arduino Library](pu2clr.github..... The AKC695X is a family of IC DSP receiver from AKC technology. The AKC6955 and AKC6959sx support AM and FM modes. On AM mode the AKC6955 and AKC6959sx work on LW, MW and SW. On FM mode they work from 64MHz to 222MHz.
4. [PU2CLR KT0915 Arduino Library](pu2clr.github..... The KT0915 is a full band AM (LW, MW and SW) and FM DSP receiver that can provide you a easy way to build a high quality radio with low cost.
5. [PU2CLR RDA5807 Arduino Library](pu2clr.github..... The RDA5807 is a FM DSP integrated circuit receiver (50 to 115MHz) with low noise amplifier support. This device requires very few external components if compared with other similar devices. It also supports RDS/RBDS functionalities, direct auto gain control (AGC) and real time adaptive noise cancellation function.
6. [PU2CLR SI470X Arduino Library](pu2clr.github..... It is a Silicon Labs device family that integrates the complete functionalities for FM receivers, including RDS (Si4703).
7. [PU2CLR BK108X](pu2clr.github..... It is a library for the BK1086/88. The BK1086 and BK1088 are DSP receivers from BAKEN. The BK1088 is a BROADCAST FM and AM (LW, MW and ) RECEIVER and BK1086 is a subset of the BK1088 (it does not have LW and SW acording to the Datasheet).

Caro Ricardo, qual motivo de "The author of this video does not encourage anyone to buy the SI4730 for the purpose of listening to stations on LW and SW.

" Estou interessado em comprar um kit de arduino com maior interesse em receber "allband/fullband". Nao entendo muito de radio ainda, perdao se a pegunta for tola. Qual receptor recomenda? Grato
Porque na documentação oficial da Silicon Labs LW e SW não estão descritos como recursos disponíveis para esta linha de CI. Em meus testes LW/SW funcionou. Em testes feitos por outros experimentadores também funcionou. Mas não posso afirmar que funcionará em qualquer CI desta linha.
I ordered two chips from different sellers Si4730D60 H can not run them with a quartz resonator. The chip is detected, but the current frequency is 0.0000. Only if I send a generation from an external generator, the receiving part starts to work.
This problem can be a little complicated to solve. It can occur in many situations. I have observed that very few times in my experiments:
When I am powering the system using the computer USB and the computer is connected to the grid, it might occur. Please, test your system using only batteries.
If you are using the board Arduino Pro Mini 3.3V (8MHz), be sure you have selected the correct board on the IDE Tools menu, Processor: “Atmega328P (3.3V, 8MHz)”. By default, the Arduino IDE uses the 5V processor version.
Check if the RESET pin of the SI473X and the controller are well connected.
This problem also can be caused by the external crystal connected to the SI473X device (in general 32768K). This crystal needs a minimum delay to become stable after a reset or power up command. Currently, this delay is 10ms. Try to increase that delay by using the method setMaxDelayPowerUp.
Tried all options. And even all together. Also tried on different controllers. About mini and Essp32. I also have Si4732 and Si4735. Everything works fine on them. Just a mystery why? They work with an external generator.
@@СергейПрилужников Good question. I don't have a precise answer for that.
Good to know. Thanks. Good Job.
parabens muito bom onde comprou esse receptor si4730
No AliExpress.
@@pu2clr obrigado vou tenta montar um
Comprei um c.i. SI4735 e acredito que pra meu azar veio bichado ,desisti deste projeto e parti pro QCX só o receptor. Parabéns pelas suas montagens.
Acho difícil ele ter vindo com problema. Já comprei de vários fornecedores. Nenhum deu problema. Por outro lado, o QCX parace ser um projeto mais robusto. Muito interessante.
@@pu2clr sir good afternoon. I ahve an si4735 module. But I would like to know what other components did you attach to the module. Do you uave a schematic and BOM
@@christophermontilla4748 did you see the page about this project? Please, see: github.com/pu2clr/SI4735
Can si4735 sketch using to si4730 module ?
Yes, you can use the same sketch. However, if you try SSB mode, it will not work with SI4730.
Does the SSB patch also work on this module ?
At the end of this video and also the documentation link about the test explains that.
