The new LD-11is Digital Direct Conversion, SDR type, build-in CPU (SM32a) DSP radio in which RF signals are directly converted to a digital data via differential and balanced A/D converters. This enables direct sampling with extremely low phase and floor noise.
The DSP is unique and features two independent channels. It also employs a unique differential algorithm within the software which is applied for IQ processing of the channels with phase suppression of the unwanted side-band channel.
The balanced ADC and DAC gives additional noise floor reduction and the receiver can handle interfering signals that are 100 dB stronger than the desired signal at a frequency separation of 10 kHz, and is about 130 dB stronger at 50 kHz separation. As the receiver and transmitter are using the same DSP channel, there is no gap between the receiver performance and the transmitter performance. Thus, there is a clean neighborhood on the bands. At the development stage, our intentions were motivated by the TX side-band noise of existing SDR manufacturers, so our aim was to fully equalize our transmitter to have noise performance that is compatible with the best modern receivers, or even better. After a arduous year of development , we think we achieved it!
This 11+ band radio is based on the LD-5, which has proven to be one of the most exciting QRP transceivers introduced in the last few years. Quite frankly, the performance rivals high end units offered by other manufactures at a much lower price point. Our motto is that we make QRP transceivers that you will want to take out in the field (without fear of breaking the bank).

Please note that when you purchase this unit, you read the manual very carefully. Take special care to use only approved connectors, proper antennas, 50ohms dummy loads and carefully check voltage and polarity of your 12VDC power supply or battery. Check all buttons and inspect after delivery. Once you verify reception and SWR, then plug in your mic and other accessories. All 3.5mm jacks are stereo jacks.
