Dear friends and fans of software defined radio and free/open source radio topics in general, next year's FOSDEM (the free and open source developer's meeting in Brussels, Europe) will, once again, feature a track on Software Defined Radio and other radio-related topics. Therefore, we invite deve

James, GRCon 2017 was in San Diego, and attracted a big crowd (lot of locals too). So there's that. In northern California, Balint hosts the Cyberspectrum meetups: https://www.meetup.com/Cyberspectrum/ ...but I see you already joined those. -- M On 10/05/2017 02:09 PM, James Wanga wrote: > Hi

Streaming (not losing a sample) is different than just “observing” something. I can capture a buffer of 2 million samples at 50MSPS (20 milliseconds), and stream that back slower – that’s longer than the PPDU (PLCP frame) size (5.484 ms) of 802.11ac I agree – that’s sub optimal if you want to c

Hi Mark, I can't find the commit right now, but there was a change where we enabled the setting of the executable bit for top_block files. Might have happened in between these two versions. Can you check (ls -l top_block.py) whether the 'x' bit for the owner is set? Best regards, Marcus O

Hello Robin Getz, and to whom it may concern: Sorry, the number was not based on my experiences - When I said 4MS/s, I was referring to the spec sheet ( https://wiki.analog.com/university/tools/pluto/devs/specs ) and personal experiences from someone else. Maybe that was an outlier, however. If i
