Re: Stuttering

Simon Brown
 

Hi,

 

No logs at the moment please, will not be coding much over the weekend.

 

  1. What bandwidth are you using?
  2. Any Wi-Fi in the links?
  3. Have you increased the buffer size in the Client?

I have this problem and tried 3.0.2, but it remains. I have read this thread and gone through all the steps prescribed here http://www.sdr-radio.com/Software/Version3/Server/ServerConsole, but no joy.

I have a dedicated server with no other software running (no VB Virtual Cable). It's is a Lenovo M93P, Intel i5-4570T Processor, 8GB RAM, 500GB HDD, Windows 10 Pro.  I'm running an internal hard-wired LAN. I have two radios (Perseus and RSP1a) connected and defined.

The stutter is not there when accessing the server with Console on the same machine. The stutter is there when accessing it via Console on any other PC in my network  - even when the client is a laptop connected to the same switch as the server. 

Next steps?  Do you want to see my server logs and console logs?

Re: Lime SDR Mini - Odd Two Peak Pattern on Many Frequencies

Thanks, Simon.  Will do.

I also suspect it's overheating.  I left it on the WX frequencies about and it was fine.  I just checked and now it's all noise.  The signal history log has it going to noise at about 5 minutes after I started it and I just plugged it in right before that.

I have the aluminum case version.  I might need to buy some heat sinks for it or figure out if the case can be removed.

Joe, If you notice my first message in the thread, you'll note that I am using ONLY the charging cord supplied with the phone, NOT the 115VAC charger. You don't need that. What you need is a charger
CORD that has a USB male plug on one end, and a mini plug on the other that fits the phone charge jack, AND a USB adapter for your lighter socket that puts out 5VDC. The one that I have tested is described
fully in my FOLLOWUP message in this thread. In this case, there is no device that is creating RFI. I can't say where I bought the lighter adapter plug, but most likely Amazon. The adapter comes either in white or black. Since the adapter puts out 5VDC, and has two USB outlets, for a total current rating of 3.1 amps, I'm pretty sure your SDR could plug into the other port.

I am sort of surprised that your device contains a switcher when all you need is 5 Volts DC from a 12 to 15 volt cigarette lighter socket. I would put a 5V series regulator in the charging device and it
would make no RFI at all. Perhaps there is one made like that. I have a two-port lighter plug with USB jacks on it. I will take a look and see if it generates RFI. And my phone came with a separate
charging cord compatible with a USB jack, which the AC charger has on it. (And IT is a switcher of course, sind it plugs into
In the meantime, Does the device you have have a built-in charging cord that goes to the phone, or do you use a separate USB to phone cable? If it's a separate cable, then disconnect it and see
if the RFI goes away sufficiently to listen to the radio. If it does, then get some ferrite snap-on RF chokes and run the charging cord thru about three of them right next to the lighter socket.
If that doesn't work, you will have to find a charger made with that series regulator.

Followup:

I just tested the 5 volt adapter I have. I connected it to a 12 volt power supply, and the output of the adapter to a CD Player with headphones. At the same time, I had an AM/FM portable radio
on the table about a foot away. Altho I have a fairly high AM noise level here, which I have not been able to find, the AM is perfectly clear, altho a bit noisy. I am about 60 miles from the New York City station.
There was no difference in the noise level with the power supply on or off. When on, I played a CD on the player, and it played clearly also. I then switched the radio to FM, and again, there was no
audible noise change when the CD was playing or when the power was off. Obviously, this is a linear voltage regulator design. (It should be noted that only one of the two negative input springs is connected.)
The power adapter has, as I mentioned, two USB jacks. It is marked "USAMS" on one side, and on the other side is marked in four lines, from top to bottom:
    "INPUT 12-24 VDC
    "OUTPUT 5V (polarity symbol) 3.1A
    "10 CE                                               <<<(the 10 is surrounded by two arrows in a circular pattern, one above, one below)

MORE followup:

Just in case the phone could be the problem--I didn't think it would be, but in the interest of science, I connected my cell phone thru its supplied charger cord to the adapter. The phone is a
Motorola "DROID" smartphone. It is charging perfectly and there is no difference in the AM noise whether the power supply is on or off.

I was able to duplicate the problem by launching SDR Console, then going to another frequency and then going back to the first one.  Relaunching SDR console solves it and stop and restart sometimes solves it, until I change frequencies again.  Attached are screen caps to illustrate.  No settings or antennas were changed between these 3 caps other than going to another frequency and then going back to the original.  I tried both antenna "ports."  It didn't happen the first time but it did the 2nd.  Now when I relaunch SDR Console it doesn't go back to normal at the moment.  Fun stuff...

In fact the Medium Wave interference doubled in strength but there was an

It was the UPS turning on and powering most of the computer hardware plus a

Ok that’s great. Background: As one of many NASA volunteers in the RadioJove amateur radio astronomy group we monitor Jupiter, solar and other objects 24/7.  NASA has a contract with UCLA to analyze and archive the volunteer data but it must be in RSS format. We have used Flagg FSX receivers and SDRPlay in the past with RSS but with limitations. The LimeSDR-USB to SDRConsole would be a great upgrade for our 15 to 30 MHz work.  It will also allow even wider bandwidth if necessary if it can be interfaced with RSS. Any help will be greatly appreciated by all. We know your busy with many other projects but hope this could be added to your calendar. You can be extremely proud of SDRConsole. It is a wonderful software. 

Thanks.

Ah,

 

I forgot to answer. There is an interface with RSS which could be supported, but it requires work from me .

Re: Lime SDR Mini - Odd Two Peak Pattern on Many Frequencies

I was able to duplicate the problem by launching SDR Console, then going to another frequency and then going back to the first one.  Relaunching SDR console solves it and stop and restart sometimes solves it, until I change frequencies again.  Attached are screen caps to illustrate.  No settings or antennas were changed between these 3 caps other than going to another frequency and then going back to the original.  I tried both antenna "ports."  It didn't happen the first time but it did the 2nd.  Now when I relaunch SDR Console it doesn't go back to normal at the moment.  Fun stuff...

OK,

 

Thinking more about this – I need to know exactly what you want and links to any data formats / interfaces. Provide this info and we’ll see what can be done.

Mike,

 

I’m guessing it’s the settings in the .ini file. I’m not familiar with lime’s software which is used to create this .ini file.

I'm getting this pattern at many bands that I've tested on the Mini.  I've tried different bandwidths and with enough fiddling it will sometimes go away and be flat again.  Must be a bad setting somewhere.   It's generally ok in the V/U ham bands if that means anything.  I am using a V/U vertical right now for wideband receive.  I will try another antenna, but this seems like a software side problem.  Any thoughts?

Thank you,

Mike
