Build Your Own Vintage Radio Broadcaster
The Elektor AM Transmitter Kit allows streaming audio to vintage AM radio receivers. Based on a Raspberry Pi Pico microcontroller module, the AM Transmitter can transmit on 32 frequencies in the AM band, from 500 kHz up to 1.6 MHz in 32 steps of approx. 35 kHz.
The frequency is selected with a potentiometer and shown on a 0.96" OLED display. A pushbutton allows toggles the transmitting mode between On and Off. The range of the transmitter depends on the antenna. The onboard antenna provides a range of a few centimeters, requiring the AM Transmitter to be placed close to or inside the radio. An external loop antenna (not included) can be connected to increase the range.
The Elektor AM Transmitter Kit comes as a kit of parts that you must solder to the board yourself.
Features
The board is compatible with a Hammond 1593N enclosure (not included).A 5 VDC power supply with micro-USB connector (e.g., an old phone charger) is needed to power the kit (not included). Current consumption is 100 mA.
The Arduino software (requiring Earle Philhower’s RP2040 Boards Package) for the Elektor AM Transmitter Kit plus more information is available at the Elektor Labs page of this project.

The nRSP-ST is a networked general coverage radio receiver for frequencies from 1 kHz to 2 GHz with up to 10 MHz of spectrum visibility. The nRSP-ST is your own personal remotely accessible SDR which can also be shared with a small number of trusted friends or colleagues.
The nRSP-ST addresses the needs of radio enthusiasts who want a 'plug-and-play' solution for remote reception. As well as achieving this, we have addressed typical internet bandwidth limitations with the creation of a novel IQ Lite mode, which efficiently delivers channels of IQ data. We are also introducing the ability to control and store IQ recordings at the remote location. The nRSP-ST is ideal for anyone wanting a wideband remote receiver without needing computer skills and hours of set-up time and ongoing maintenance at the remote location.
Features
"Plug and play" integrated, networked general coverage receiver:
Combines a receiver, a host computer and a whole lot more – all in one box!
Apply power and connect to the internet (Ethernet or Wi-Fi) and the nRSP-ST is automatically accessible from anywhere
Multi-platform SDRconnectTM software supports local operation or remote access on Windows, MacOS or Linux platforms
The nRSP-ST & SDRconnect are configurable for available network bandwidth:
In Full IQ mode, the nRSP-ST provides IQ data transfer of the visible spectrum bandwidth (e.g. for high-speed LAN or superfast internet connectivity)
In IQ Lite mode, the nRSP-ST provides IQ data of channels up to 192 kHz wide (e.g. for digital decoding by the client)
In Compact mode the nRSP-ST provides compressed audio (ideal for slower internet connections)
Supports multiple client connections with a simultaneous mixture of connection modes – an admin tool allows you to assign usernames and timeouts to trusted friends or colleagues.
All modes support visualization of up to 10 MHz spectrum bandwidth
Two remote connection options:
Use a remote SDRconnect client or
Use the built-in web-server for remote access from any web browsing capable device, including Android/iOS tablets and phones
The nRSP-ST offers the ability to record IQ and audio files to a NAS (network attached storage) device if available on the LAN.
The 14-bit ADC full featured wideband SDR receiver covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps
