Daytime power is now 850W and nighttime is still 250W (or as they say, "Two hundred and fifty thousand milliWatts of power. To the people.")

They've also been having problems recently. For the past couple of weeks(?) their audio source has been breaking up/skipping. That seems to have been straightened out, but now their xmtr seems to go off the air. They're off now (June 12, 2016 2330 UTC) and have been off for an hour or so. Was listening to them earlier without any problems, then they went off.

Good luck in catching them, they're a tough one for you. But keep trying, perhaps greyline might be the best. Their daytime pattern sprays a bunch towards the E & SE. Nighttime sends it to the SW with very little to the E or SE.

In the TV series "Defiance", the aliens referred to humans like that.

Sounds like your GF is an alien and slipped up referring to you.

Finally got the radio hooked up with a good antenna to listen w/o overloading it. AM stereo sounds so very, very nice. The wideband audio + the stereo separation.

Have tried SoDiRa with the Perseus, but can't make out the separation.

Software / Re: SDR programming?

« on: June 01, 2016, 0134 UTC »

Cool, thanks. I think I tried that way back then, but don't remember where I put the app (I tend to put things "for safe keeping" after a while, which means they get lost. For the longest time, I kept doing that with one of my books. I've finally found it again and not going to let it out of my sight. Ever).

And if I can peek at the source, I am definitely interested.

Hopefully I don't have to wait until after:

Software / Re: SDR programming?

« on: June 01, 2016, 0119 UTC »

I took a quick look at RFSpace for their models, but WAY above my budget (although, specs are perfect, esp that NetSDR+ with a couple of the options).

CloudIQ may be in the realm of possibility at some point this year. Are you familiar with that one?

Didn't know they released CuteSDR as open source and there is also GNU Radio. Those should be a great start.

The Perseus software does save files and I have TB of them (as well as from Studio1). And, that's another thing I'd want to do is to be able to read in recordings and do analysis on them, as if it was live. I know third party can do something with Perseus as Studio1 does. They interface to it via the a DLL, but that does me no good whatsoever on Mac, FreeBSD or Linux.

I do remember seeing the carrier drift articles, nothing short of fascinating and have read them several times. Do more!

Software / SDR programming?

« on: June 01, 2016, 0008 UTC »

I have a Perseus, but want to do some stuff that isn't possible with the std GUI software.

Initially, I want to choose a bunch of frequencies to track & record the signal strength of a signal on a frequency, 24x7. Since carriers aren't exactly _right_ on a specified frequency, need to have a sludge factor of +/- 100 Hz to find the thing nearby and then track it. If it goes beyond +/- 100 Hz, then it can be forgotten about.

The input would be a list of frequencies and a name of the log file. The output would be the frequency, date, time, and signal level. Maybe shift from listed frequency, but since my Perseus doesn't have one of those high precision oscillators, I wouldn't put too much into adding freq drift.

In the GUI, the Perseus can go up to 1600 kHz of bandwidth received & demodulated, but they have a little program that displays the entire 0-40 MHz spectrum, but not in great detail. Which tells me this thing can go very wide, but in limited means. All I want is amplitude. If I have to restrict to 1600 kHz, well, not ideal, but will still work with that.


Down the road... want to do more and be able to specify freq + bandwidth and record AM/SAM signals. Scattered across the band, possibly simultaneously on a schedule.

And all via CLI only, on Mac, FreeBSD and/or Linux. No fancy GUI nonsense.

So The Question® is, where to begin? 

I have a book on DSP, can do Perl and some minor hacking in C.

While I'd like to use the Perseus since I already have it, I would not object to buying a less expensive SDR that may be easier to program.

Would also like to get an SDR with the 10 MHz reference to study the frequencies of the stations, incl the time & freq standards. How does WWV's signal shift by the time it gets here?

0145Z 25442 S3 YL talking.

They started late as what sounded like transmitter problems with it having a hard time staying on the air. They did get it to stay on with no audio, but as soon as they put audio, it dropped. Eventually got it going.

Signal wasn't all that strong. Unknown if that's normal or they were running at reduced power related to the xmtr problems.

Has been going on now since 2345 UTC today (22 May 2016) on the U of Twente's WebSDR. Nothing on my receiver here (but too light for that frequency, if they're over in Europe).
