Issue on FM when running 3072/6144 BW (ELAD S2)

Patrick
 

Hi Simon es Group,

Attached is a capture showing what happens when running 3072 or 6144 BW on my ELAD S2 (upper side of the waterfall).
Back to normal when switching to a lower BW.

NOTE : it ALSO occurs with SW2 native software, hence this is not v3 related. But I'd like to understand what causes this problem (using an i5 laptop, 16 Go RAM).

Well,

 

That’s the sort of idea.

You could use a cloud service (like Dropbox) and appropriate sync software to keep all your devices "favorites" file (and anym others) in sync. That's what I do. I have 3 PC's 3 laptops, 6 tablets and a smartphone or two. WFM!

That is great Bob. Years ago when I was doing this there were several weather sats, both American and Russian. Now there are only a few running and all of the Russian ones are dead. If you didn't have a radio like the ICOM, you had to build a crystal controlled radio to receive the sats and feed the sound to your computer. Then they changed the frequencies and you had to try to find correct crystals. I wished I had a dongle then.
[]
======================================

Yes, there are still three NOAA satellites on APT (137 MHz), and at least one Russian one which is now delivering data digitally on the 137 MHz band using a coding called LRPT. Instead of two channels there are three, and the resolution is some ten times better, so the image quality on 137 MHz can approach that of the HRPT images which are still transmitted on 1.7 GHz by the NOAA satellites. They can be quite stunning, and you don't even need a tracking antenna. Yes, they can be received with a low-cost dongle, or an Airspy receiver (others are available).

There is a plug-in for SDR# which decodes the LRPT data, and a Doppler shift module as well (although I've not found this necessary). IIRC there's a decoder which could take an IQ file from SDR Console.

It's a pity that NOAA chose not to equip the newer satellites with a VHF facility, which would have allowed an omnidirectional antenna to be used (useful for ships as well as amateurs).

Cheers,
David

Back in the late 90s you were also able to receive Geo Stationary Weather Sat signals.  I built a 1.5 meter dish in my back yard (yes you can use a surplus old-school sat TV dish instead but I wanted to see if I could do it) and put a coffee can at the point of the signal with a small antenna inside of it.  My ICOM radio was able to clearly hear the signal at 1,692 ghz.  Now the dongles we have today will be more sensitive and would work better. 

Here is a link to a photo of the eclipse of 2006 over Africa taken from a Geo Stationary sat:

Here is some additional info for anyone who has the time to try the Geo stationary sats

thanks Dwight and David.
I just copied/printed my first Wx Sat picture off NOAA-19

using the link u gave for SDR and an RTL, and D/L'ing WxtoIMG, I got a
nice picture scan of pretty much Kentucky in the center.

been a Ham since '58 and never tried this.

Hi,

This is something I've thought about and would like myself. I don't have a perfect solution at the moment...

Dominic,

I've not been able to check this, but having just a central file accessible by all PCs? Failing that, if software doesn't allow you to specify a central location perhaps....

1 - you could use DropBox (or Google Drive, or One Drive?) to share a file across several PCs.

2 - you could wrap the invocation of the software in a script which copied the files from the central location to the local disk at the start, and back again at the end.

Let's hope (1) and (2) aren't needed.

Cheers,
David

If this is even possible, I'd love directions.
I have Version 3, Build 811 installed on several PCs around the house; two Windows 10 desktops, one Windows 10 laptop and a Windows 7 laptop.
I would love to sync my favorites among all of them. If I add a favorite while listening in the kitchen, I would like it to be available to me when I use a laptop in the bedroom.
Is it possible to keep a central favorites file and share it on the network? I use an Afedri SDR-Net with SDR Console over LAN, so I like to move around.

Thanks,
Dominic

Google xmarks this will do what you need. Be sure to turn off any synchronization in your browsers as this will confuse Xmarks, depending on your browser you will need to download extensions from the browsers extension store.

Re: RasPi failing to recognise RTL dongle on start-up

It looks like a power issue, try to use a higher amperage 5V PSU for the RPi, 4-5Amps maybe.

Re: Solar Eclipse and Weather Sats

not sure of your setup but, you may have to download virtual cable so the program has a way to hear your sdr.
 I've been using sdr and WxtoImg for years....it does work well.
 An antenna dedicated to the 137 mhz band will help tremendously.

Virtual audio cable of some type. Many on the net.

RTL-SDR ->receiver program->virtual audio cable->program to consume
audio (wxtoimg)

This is the virtual cable I use: http://www.vb-audio.com/Cable/index.htm

I use HDSDR to convert the samples to audio. Set the audio output to
one end of a cable, the other is the input of your favorite program.
In this case, wxtoimg.

Sounds like a fun time. Who said ham radio was just decrepit oldsters
complaining about colonoscopies?

Is there any work around for this issue?

I didn't find a work around with SDRconsole.

Have a B210. There are several other methods for geting the radio to play.

SoDA radio: http://sodaradio.sourceforge.net/Site/SoDaRadio.html

Windows GNUradio: http://www.gcndevelopment.com/gnuradio/

HDSDR.

Been working on various other parts of my portable station. This
(portable VHF/UHF SDR for satellite) is coming back around in
November.

I try to waste time where there will be returns of some kind.
