Software / DIGTRX - No RX Signal

« on: March 21, 2018, 1455 UTC »

Following this thread: https://www.hfunderground.com/board/index.php/topic,32986.msg123254.html#msg123254 I was able to get DIGTRX running on my Windows 10 computer. I'm monitoring using web-based SDRs, mostly from the KiwiSDR network (http://sdr.hu/).

My problem is I'm not receiving anything on DIGTRX. I'm guessing there is some setting I haven't configured correctly, but I'm at a loss as to what it might be. Hopefully, someone here will be able to help me out.

Thanks,

HF Mystery Signals / Unidentified Signal, 11591 kHz, 19 March 2018 1817 UTC

I saw this signal when I was recording HM01 at 1755 UTC I began recording it at 1817 UTC.  I had the software running in AM mode, but I have no idea if this was the correct mode or not. When I checked back later (around 1840 UTC) the signal was gone.

Recorded using a remote receiver in Idaho, USA

Heard using webSDR located in Enschede, Netherlands.

17/00 repeated for 3 minutes 45 seconds followed by "out". End of transmission.

Thanks to Ary-B for explaining what "oblique" means in another thread. I couldn't make out the word until I read that thread.

Thanks Chris. Other than the fluctuating ppm numbers things seem to be working fine.  I don't think I'll mess with it for now.

Would a new computer (2016 build) not have autodetection?  I'll try to get a crossover cable tomorrow and give that a try.

Connecting the SDR directly to the computer's ethernet didn't work - the SDR was not recognized by the software.  I'm back to using it connected directly to my router.

Thanks for the help.

Software / Re: Question for SdrDx Users

Thanks for the replies. Following an uninstall along with cleaning out my registry, I just installed the latest version (2.17r). When I first start it, I'm getting a missed packet reading in the hundreds, but if I stop and restart then the Missed packets go to zero. the ppm reading begins around -90 now but drops to about -15 to -30 over time.

Chris - I only have one ethernet port on my computer, should I connect the SDR to the computer and then connect the computer to the internet via wifi?

HF Mystery Signals / Re: UNID Frequency Hopping 1023 UTC between 6436 and 6294 kHz Possible Radar?

« on: December 11, 2016, 1616 UTC »

WoW! I got one right 

I forgot to add that this was received the hardware and from the location in my Sig.  Software was SDR Console (v3). I'm really surprised that you think it is out of Australia, given my less than ideal antenna location.

Software / Question for SdrDx Users

« on: December 10, 2016, 1831 UTC »

I'm using the Windows version, but I think this question isn't OS specific.

In the lower left corner is a window that after starting the software displays "AFEDRI-SDR Connected" - I'm using an AFEDRI SDR-Net. After selecting "Run" This windows displays "AFEDRI-SDR Running 120ppm MP=-4837".

Can someone explain what the "ppm" and "MP" mean and is there a certain value I should strive for?  The SDR is connected via ethernet.  I'm running Windows 10, if that makes any difference.

Thanks.

Software / Decoder Software for Windows 10 Suggestions?

« on: December 01, 2016, 0104 UTC »

I'm currently running SDR Console (v3) with an AFEDRI SDR-Net on Windows 10. I'm looking into decoding some digital stations and would like some recommendations on software. Since I'm just getting started in digital, I can't be more specific as to what I want to decode, so I guess I'm looking for something that would be kind of general purpose until I get a better idea of what I like and can receive with my current setup.

Thanks!

Is anyone familiar with this book? The author is Roland Proesch. I'm thinking about getting it, but would be interested to know if others have it and their opinions.

Thanks.

Spy Numbers / HM01 20-Nov-2016

« on: November 20, 2016, 1926 UTC »

05:59:20 Recording catches the transmission in progress. I wasn't aware of the hh:57 start time, so I started my recording 40 seconds before the hour. A lot of noise and the transmission fades in and out. last heard at 06:05:10.

06:26:45 I had my recorder set to record for an hour, so I was able to catch this at the beginning. I completely lost the transmission at 06:27:30.

All times UTC.

Using my Afedri SDR-Net and SDR Console (v3).

While trying to receive WWV at 20KHz I noticed this strange "zig-zag". Look at the left and right of the waterfall.
