Simon,

I just tested it and found this error in the log file:

17:32:11.386: Radio LimeSDR> Calibration error - Rx calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?)

What's the best way to post the log here, since it's quite long, if you want to see the whole thing?

Thanks,

Re: Automobile Cell Phone Charger RFI (MORE followup)

The charger is plugged into the 12v socket all the time and by itself I get no interference at all But as soon as I plug the USB cable into any device I have trouble hearing FM and it wipes out AM totally.. I looked at it today to see if it was easy to take apart but its not it is all glued togeather that would break it if I tried to separate it.

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)

Joe,

I surrender! I suppose I should have started my testing in the car. Joe and crew are correct! The adapter DOES create interference on the FM band. I am going to try and find out why, which means
that I will have to crack open the shell and find out what's inside. Probably will not be able to put it back together with whatever fix is required, but I hope I'll figure out what's causing the noise.
I do know that it does not seem to make a significant difference whether the phone is plugged into the cable or whether the cable is plugged into the adapter. (Of course, the socket in the car
is not rated for an actual cigarette lighter; you're not supposed to smoke anymore!) I tried ferrites on both ends of the charging cable without result. Apparently the noise is getting back into
the car's wiring and radiating into the radio from there.

Well, I sawed the housing apart, and sure enough, there's a little oscillator circuit inside, with a tiny coil, several SMD resistors and capacitors, and a chip from CHN, (China Semiconductor),
marked HC8816 and T746. I can't find HC8816 in a quick search, but it is obviously the oscillator/regulator device.

A crude and clumsy fix would be to obtain a lighter plug with no electronics inside, and a lighter socket with no electronic inside, and wire them together with ferrites on the wires, and some
decent capacitors across the wires at the input and output sides--around 47 pF would probably be a good starting point. It would then probably be necessary to put ferrites around the
cable to the phone and the SDR input wires, right at the USB outputs. You would obviously need to shield and filter this contraption. If I am going to ever try and solve the problem for my
own use, I would just build a linear regulator with a 7805 and, if necessary, a pass transistor, and the necessary bypass and filter caps on a little board, put it in a little box with a lighter plug
on one end and one or two USB jacks on the other. If you are going to want to run your SDR from the car, you will need to do something like this. If you just want to charge your phone,
do it while you're having dinner, or something, assuming the lighter socket is still alive when the key is turned off. Or just remember to charge your phone at home!

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

If that doesn't work, you will have to find a charger made with that series regulator.




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

I have been wondering about a heat riser dimentions from the GPU and Radio to the case ... it make silly uber sense to use the case as a heatsink .... 

Why transfer heat to the inside air, then from the inside air to the outside air !!!!

Iv been thinking of how to make very close measurement my self ... and all i can come up with is using 2 toothpics that are rubber cemented to the case == GPU then also Radio ( not necessarily as a single block ) ...  

Make the connection so that it can accordion in some way .... and put fresh/wet glue on the toothpicks and put the case on and let it dry ( with the ends off ) open it up after ... toothpicks come out easy from rubber cement ( i hope )

Re: Stuttering

Hi Simon

  1. Server bandwidth is 2,000 KHz with compression. Throughput (?) seems to be between 1,000 - 1,500. I'd like to start the Perseus with 250 or 500 KHz. I've tried to start with 192 KHz and sometimes that makes a difference, but not always. I like to start RSP1A in 1 MHz (for BFM) and have tried a start in 150 KHz, but if I move up past 250 KHz stutter comes back - so 200 is max.  
  2. No Wi-Fi
  3. Yes. I tried all IQ Buffer sizes. Makes no difference. All scenarios listed in #1 were at 100 ms.

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 .

Ah,

 

Thanks. I think RSS really wants me to act as a server, it saves the .sps file from my data. I’ll look at the interface and see how complicated it is.
