3.0.27 Binaural

Sorry to be a distraction, Simon...
Are you willing to share the design differences between your/Moe's new SAM implementation and the "old" AM version?
Before this, I assumed binaural was already carrier-synchronous.
Many thanks
Paul

Re: Dangerous Pluto transmit bug found

Don't know if it's the Pluto, or Simon's mega VHF beam pointing in the wrong direction.

Re: Multiple receivers at same time

Hi, i think that is not possible in one and the same SDRC instance and with the same radio. I don't understand these things too well, but gather something like the Flex can have multiple ADCs and process them "simultaneously". An RSPduo has (real or virtual?) twin ADCs and can multiplex their outpu...

Re: DXGalaxy.com

Over the years I have grown to despise the concept of a Microsoft web browser. This is unworthy rhetoric couched in smart-ass language. Why would you hate the "concept of" a Microsoft web browser, or anything else? Give me fact-based critique of specific aspects of specific software. Even give me r...

Re: A.M. Modulation Index & Bandwidth

"filter the thing to the desired audio bandwidth" then apply the mag function to the complex data out of the filter, sqrt( re^2 + im^2). OK, Joanne, just waking the brain up a tad... Does that just mean: within one RX BW, for every bin (except zero/DC taken separately) do |x|, then take the average?...

A.M. Modulation Index & Bandwidth

Just curious... I sometimes see broadcast station reception reports with comments along the lines of "very low modulation", "over-modulated" or "excessive bandwidth". Are these properties that SDRC could calculate (and display on demand), and would any more sane people find that interesting/useful? ...

Re: Christmas Stocking one day?

If anyone has half an hour plus to spare, and would like to know what all the fuss is about with (Perseus) Jaguar Pro by Ilpo Parviainen (and so why I believe it is worth studying for lessons/ideas for any other SDR program), these are the only two YouTube review videos I found on the subject. Both ...
