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...

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 th...

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 ...

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 ...

Data File Analyser (V3.0.26) Frequency Displays
Using low-performance laptop with Win7, data file recorded from Elad FDM-S2. Haven't yet been able to spend much time exploring this program, which seems to have super potential but gets hardly a mention here. Can someone please explain an apparent oddity? When creating the project I used the overri...

Re: Exploring Single Frequency Networks (SFN) on MW
I can see you building a picture of your environment. That would be an estimate of how many signals you could receive if all the others momentarily went away. Yes, that's a better way of putting my objective, I suppose. " The delays are not likely to be constant from day to day and may vary no...

Re: Exploring Single Frequency Networks (SFN) on MW
Given that these networks exist and you can hear variable beat notes or even see them on a spectrum display, how do you distinguish a single station received via multiple paths from multiple slightly offset transmitters? Joanne, thanks for hat, and your other suggestions. Of course there are limita...

Exploring Single Frequency Networks (SFN) on MW
DXers are getting used to measuring persistent/stable frequency offsets to help identify some individual stations. Time Difference of Arrival (TDOA) is a transmitter location technique using triangulation based on signals from different receivers (e.g. KiwiSDR). TDOA is beginning to make geographic ...
