    I am proud to announce that the SDR++ #Falcon9 live decoder is almost done!!! Managed to get it down to 15% CPU total! This module makes decoding the falcon9 as easy just clicking a button. I hopefully will release it tomorrow, so stay tuned! #SDR #SDRPP

    This is what 4 years of #SDR software development looks like...

    The first prototype is almost ready to be sent to the assembly house. This is an 8 channel, 8MHz bandwidth, 12bit coherent #SDR receiver with 25 to 1750MHz coverage for only $350. The channels can run in coherent groups or even alone to get up to 8 independent channels.

    How many of you would buy an 8 channel coherent #SDR with 8MHz of bandwidth per channel, 25 to 1700MHz coverage, 12bits of dynamic range all for around 350$? Also the channels don't all have to be coherent at the same frequency, you could create several groups for multiple arrays

    The first DragonLabs CR8-1725 8 channel coherent, 25 to 1750MHz, 12bit, 8MHz bandwidth SDR receiver PCBs have arrived today. Assembly of the rest of the parts as well as the bringup will take place next week. #sdr #rf

    Almost 4 million #FPGA logic units (8x XC7K480T) and 32GB of ram. Gonna stick all of them in a server for heavy DSP and simulating custom multi-node RISC architectures.

    More or less finished the DSP for the SDR++ Analog Video decoder. The VSB auto gain control still needs a bit of work but I think it's already better than every other SDR analog video decoders out there with how fast it locks and how stable it is. #sdr #sdrpp

    [Thread] Since last weekend I've been working on a new high data rate ham radio mode called #RyFi for IP over the air which focuses on reliability without sacrificing on speed. See the end of the thread for some demo screenshots (1/6) #sdr

    Mysterious new signal around here at 424.813MHz. FM modulated, 12.5KHz bandwidth, 2FSK subcarrier at 1800Hz with 1200Hz deviation. Data is 2400baud, sync word is 0xE5FF9F (3 bytes exact), followed by 4 bytes of data. No encoding or FEC appears to be used. Anyone know what it is?

    More of less done with the #RF over #Ethernet PCB. Just gotta refine the inductor choice a bit to avoid self resonance issues, but other than that it's more or less ready to get made! The removed solder mask is a bit overkill but looks cool, so whatever...
