We always smile when we think that AM is still alive and kicking. It is in recent versions of this library, though. It appears the chip has the technical capability to receive single sideband, but it requires a poorly documented patch. According to, he used a 4730, but it still did shortwave with the 4735 library.īreakout boards with the chip are just a few bucks. Confused? of the programming guide should help. For example, the Si4731 and Si4735 have the RDS/RBDS decoder, and the shortwave mode is available on Si4734 and Si4735. The chip comes in several flavors, each with slightly different features.

    The radio takes serial (I2C) commands, and the Arduino converts the user interface so that you can control it. The output can be digital (in several formats) or analog. It can even read RDS and RBDS for station information. The chip will do FM 64 to 108 MHz and can demodulate AM signals ranging from 153 kHz to 279 kHz, 520 kHz to 1.71 MHz, and 2.3 MHz to 26.1 MHz. The chip contains two RF strips with AGC, built-in converters to go from analog to digital and back and also has a DSP onboard. On the inside, it uses a Si4730 radio which has excellent performance that would be hard to get with discrete components. On the outside, it has a good looking case. A good case in point is all band radio which you can see in the video below the break. Type - There are mobile, handheld, portable, in-vehicle, marine, and base station options available.It is getting harder and harder to tell homemade projects from commercial ones.

    They transmit over the full ham spectrum and broadcast for 200 miles. Mobile or in-vehicle - These receivers connect to an electrical outlet or a vehicle's battery by plugging in a cord to the cigarette lighter or a power adapter.It uses a 12-volt battery and transmits for thousands of miles. Base station - This is a strong ham communications receiver.What are the available types of communications receivers on eBay? Choose from new or used communications receivers at a variety of price points when shopping on eBay. On eBay, there are many different manufacturers of ham and amateur radio receivers. When you want to communicate through amateur and ham radio systems, having the right receiver makes a big difference.
