This is the official channel for the GNU Radio project. GNU Radio is a free & open-Source toolkit for software radio, and is used by thousands of engineers and scientists around the world.
Our monthly project calls are streamed live from this account, and recordings of talks from each year's GRCon are posted here, as well.
Hey. Can you help me? We are working on OFDM video transmission with a GNU radio, one receiver and one transmitter, but we are having trouble sending video. Can you help us overcome this problem? When sending the video, the file size increases and there is no sound or image.

Are you taking into account the turn around time from receive to transmit ? There must be a delay time ! I'm not sure I see the point of this. It looks like radar, but the distant object is an active device, not a passive device. Today, cheap Lora devices with built-in GPS do everything that is required. The antenna you were using is a log periodic antenna, and it looks like you are using it back to front. I can't tell for sure from your photos.
The biggest problem getting worse is the growing cold war any active clandestine war with China. Will we buy ham radio after they invade Taiwan? Or after they annex Micronesia? I guess that depends on whether you love your country or theirs more. I'm just not impressed with Tid radio or Talkpod or Temu or whatever the latest hustle from China on hamtubers that they jump on like free drinks at the moose lodge.
Please work on your presentation skills, ask and answer questions along the way, you’re too monotone. We need more DSP guys in the US but right now we’d be killing alll interests if we depended on this video. If I presented like this at work, I’d be butchered and yelled at and nobody would’ve listened. Universities need to get themselves higher standards man what a pitty.
You started off with some constructive feedback then dove right into bashing someone. I'm a novice in this videos topic but I found the information very useful. The presentation style seemed to be inline with how other technical presentations I've seen are done as well. The audio is low but I can clearly make his words out. The video quality is more of an issue for me but I can still follow along just fine. I'd be willing to bet that none of those audio and video issues are his fault either. There is nothing wrong with constructive feedback but what exactly do you or anyone else gain by tearing others down that have taken the time to share their knowledge for free? I just don't understand the vitriol.
