This kit is intended for people who do own a STEMlab 125-14 already, which they would like to use for an easy entry into the world of SDR. Your STEMlab 125-14 will find a new life as a real entry level SDR TRX with good performance. The STEMlab 125-14 functionality will continue to be accessible on the frontpanel.
The box comes with detailed Schematics of all boards included. Currently available products are: STEMlab 125-14 based products STEMlab 122.88-16 SDR based products All products above are built around the following basic building blocks: |
|
The Software Defined Radio coreThe Software Defined Radio core – can be either STEMlab 125-14 or STEMlab 122.88-16 SDR. Specs as defined by Red Pitaya. RADIOlab kits will be pre-configured to fit the requested SDR platform. |

|
Charly 25 MainboardA 4 layer PCB which is completely controlled by I2C, has been developed to make full use of the functionality offered by either STEMlab 125-14 or STEMlab 122.88-16 SDR cores. |
||
|
Charly 25 CODEC boardA 4 layer board with excellent reduction of unwanted noise by consequently separating analogue and digital grounds. - CODEC Chip used is WM8731. |
||
|
Charly 25 power distribution boardThis board is just used for ease of DC cabling inside the transceiver. |
||
|
Charly 25 RX Preselector/Filterboard
In order to achieve an outstanding performance on all 11 Amateur Bands, the Charly 25 team had to move to an unusual PI based filter architecture which until recently was only available to Microwave – and /or commercial and military customers. |

Power SDR in the Charly 25 EditionThe Software used for these Transceivers is based on HPSDR and is open source. All changes implemented by the Charly 25 team are well documented on Git Hub and available to everybody.However, an enormous amount of effort has been spent to adopt the Software and allow for the usage of all available HW features. Power SDR controls all boards inside the RADIOlab via I2C. It: |
