Good morning David! I was intrigued by your video. I had intended to just jump to the demo, but I got sucked in and watched the whole thing.
I’ve often wondered if such a thing could be done in a practical way- looks like you proved that it can. I have a few questions: 1. How critical is the type and placement of the two antennas? Do they need to be identical? Any proximity constraints? 2. How much audio delay is introduced on a received signal as compared to the audio output of the rig itself? In other words, is it useable when in an actual QSO, or is the delay objectionable? 3. I assume any phase-locked dual-receiver rig should work- do you know whether it has been successfully used with a SDRPlay RSPDuo ? I have one of those lying around unused at the moment, so I will give this a go when I get time to do so. Thanks for your time. Great work! 73 de W0ZF On Fri, May 22, 2026 at 2:36 AM David Gilbert via Elecraft < [email protected]> wrote: > > I recently posted a link to a video of a browser-based application I > created with the help of ChatGPT to enhance diversity reception.
