This is how OSL calibration transforms the 2D space.

The very first use of the CMX918 chip to receive SSB. Demodulator is based on the RP2350 microprocessor with an output to MAX98357A D-class audio amplifier. Antenna is 1m wire. #CMX918 #DRM #hamradio youtube.com/watch?v=lPEvQf…

Do you know that you can get a sample pack of 10x freshly baked RP2350A and RP2350B chips from Raspberry PI? #raspberrypi #rp2350

Do not want to buy a "CML Micro DE9180-2 Demo & Prototyping Kit for the DRM1000"? Make it yourself for $10. Now I have access to the internal I2C as well as to the digital data from the CMX918. #DRM #hamradio #cmlmicro

It looks like CMX918 is just the right chip for an HF SSB receiver. I will add more info soon. github.com/ur8us/cmx918 #hamradio #DRM #CML

Prototype boards of a new DSP/DDS modulator are coming from the assembly. 1 to 108 MHz, streaming MPX or I/Q data from USB audio or directly from Raspberry PI. FM and DRM (both HF and VHF) modes are tested OK! #FM #DSP #DRM @drmdigitalradio

Teardown of the DRM1000 module based on the CMX918 DRM tuner. "Covers broadcast bands from 530 kHz to 108 MHz." github.com/ur8us/cmx918

@ryzerth @rigexpert Thank you very much for your work!

The latest SDR++ nightly now contains support for the @rigexpert #FobosSDR. I've worked around the some hardware issues. The hardware sample rate is locked at 50MS/s or more, lower SRs are decimated in software. I found issues in the driver code, will submit fixes. #sdr #sdrpp

@ryzerth @rigexpert With a 40 MHz injected from an external oscillator just to the MAX chip:

@ryzerth @rigexpert Hi! Can we also have an option for 40 Msps? There is a mod for the receiver when a 40 MHz oscillator is installed instead of 10 MHz one, and the SI5351 is re-programmed to pass through the 40 MHz signal to all the chips. In such a simple way we get rid of most of the phase noise.
