We are pleased to announce the WonderRadio kit, the hardware is 100% compatible with PowerSDR and provides a 1W PEP SSB/CW/AM/FM/DIGITAL Transceiver Covering 12Khz to 60Mhz. A 100W Linear Amplifier would be available as an upgrade down the line. The Kit Comes Assembled and Tested and no soldering or construction is required.
The RoHS Delay has been resolved and the first batch of orders will ship on the 20th of this month.
We are in the process of starting a forum and knowledge base for our users, any ideas or suggestions would be appreciated, please email us at support@sdrtec.com
All our components are Imported from Mouser, Mini Circuits Labs, DigiKey, Motorola, we ensure that all parts including the PCB and solder are RoHS Compliant.
We are Pleased to announce that Mr Rahul Srivastava, VU3WJM, has joined SDR Technologies. Rahul has extensive experience in RF Design consulting for various companies, an avid homebrewer as well Rahul has been instrumental in promoting SDR within the HAM community in India.
Currently we are evaluating the WonderRadio with OCXOs at 20Mhz .5PPM stability as a frequency source, this option will be available soon. |
