I use my Red Pitaya for RX only using HDSDR, can I alo use SDR Radio please? It does not appear to be listed, thanks. (Nor does it "see" my LAN connected Alfredi).

In case you haven’t seen his video, here’s what the latest version looks like. The aluminum enclosure may look familiar, it’s the  box that sits atop a Heathkit Cantenna that I scrapped.😬

It definitely tamed the AM BC harmonics from 1270 kHz and 1540 kHz, both only 5 miles away on 2540 and 3080 kHz respectively!

There’s also an AS-RXFEP (RXR Front End Protector) inline to protect it from the local HF TXRs.

So you may see some QRM depending upon where you are listening and where the club radio(s) are TXing. These allow users to still use the server versus my previous use of relays that completely disconnect and ground out the RX antenna whenever an HF rig was powered up. No more interruptions for SDR users!😎

Enjoy using the KA1GJU @ PCARC server.
Let me know if you hear or see any oddities!

Are you the one in Ohio (IP location) that monitors aircraft ACARS on HF, on 11xxx MHz?🤔

As users of my "Super Stations" will attest, I have some of the most QRM free RXR's on the network.
Use Kriss's rigs daily - can confirm.

Placed a W1VLF design AM BC filter inline before and after images attached.
WXEX on 1540 kHz has a 1st harmonic that's very strong on 3080 kHz that gets squashed with the filter!

You are in the wrong group.  This group is about the SDR-Radio software.

Alguem tem ou sabe onde posso baixar o Manual ou Esquema do Gerador Sinal RF 17A ele é transistorizado e não tem
Circuitos Integrados somente transistores.  Já este modelo Gerador Sinal  model TGS 17 acha fácil mas este não é o
esquema é diferente :
Agradeço qualquer ajuda.

Well,

 

I ran the S3 and G31DDC at the same time, down at VLF / LF / MW I saw no difference. Antenna was a Wellbrook loop. Strongest SNR was ~95 dB.

 

Next week I’ll have the whole range here – G33DDC, G39DDC and G65DDC so will take screenshots etc.

How does the G31DDC/G33DDC compare to the ELAD S3 as used on SDR-Console in general terms of sensitivity, spurs, etc.?
Thanks,
Larry, K4LED

Winradio DDC File Playback

Simon Brown
 

Hi All,

 

Just fixed a problem with playback of Winradio .DDC files in WAVE_FORMAT_PCM using 32-bit integers. Fix is in the next kit, anyone who needs this right now send me a private email.

Hi,

 

I have this, on my list of things to do.

I could create a directory for a file on "the file section" here, but no response when the upload files selection is pressed so I uploaded to google drive here: 

https://drive.google.com/file/d/13mBy2G9kfQeb1XGLYVxJSJ_x6CitWPZh/view?usp=sharing

This was recorded on 80 meters during the day, so there were less real signals on the band which made me realize that there was in fact some reduction of noise with the threshold slider turned fully up, but much less reduction than SDR# can do for example.  Thanks Simon for taking a look!

I was using the double slider noise blanker, I did not realize there was a wideband blanker on the top toolbar.  The wideband blanker works OK!  I've uploaded a I-Q file for Simon, but I don't think there's a reason to bother now.  Thanks Zacharias!

Hi,

 

If you upload a data (IQ) recording I’ll see what I can do.

With Sdr-console 3.026 enabling the noise blanker has no effect on power line impulse noise at any slider settings.  Using SDR# the noise blanker works great.  Bug or just differences in the PC side software?

Zacharias Liangas
 

Which of the two you use?
The blanker from the main menu or the double slider in the dsp pane ?

Robert, this is a very interesting project.  I'm impressed!


Re: SDR meter stuck on old transmit display values #sdr-consolev3

Thanks Simon, that helped a lot. SDRC still occasionally comes up with the meters stuck, but closing and reopening fixes it.
   Thanks for the great software

Is this drift causing a problem?
I think you are being too critical.
The picture you showed was zoomed right in showing very fine detail.
If it drifts more than you want then it would be best to fit a TCXO.
