When do you expect the “Broadcast FM Band-Stop Filter” to be in stock via Amazon (USA) again? It says here it’s in stock but it’s definitely not in stock on there currently. Trying to decide if I should wait a few days or order direct from China or something else.

It’s still an RTL-SDR, so you can use any RTL-SDR software with it, be it on Windows or Linux.

But the phase coherent software we have developed for it is based in Linux. If someone wanted to, they could port it to Windows.

Even a single RTL-SDR cannot run at 3.2 MSPS without dropping samples internally. On good machines 2.56 MSPS is the maximum without dropping samples, and Kerberos can handle running all four at 2.56 MSPS. But we say 2.4 MSPS to be safe since some PCs have trouble at 2.56 MSPS even with one RTL-SDR.

ya sorry poor choice of verbiage, I was thinking about the traces/routing layers and the capacitance random/spurious and why you didn’t cloverleaf the four – but it looks like you conquered that already!

User Projects • How can I use the RTL SDR lib for my C application

down vote

I am trying to create a simple c code to listen to an FM radio channel using an RTL-SDR dongle and as a first step I looked to this rtl-sdr.c file and tried to do the same, for example :


#include <stdio.h>#include <stdlib.h>#include <stdint.h>#include "rtl-sdr.h"#include "convenience.h"int main(int argc, char *argv[])    {    int dev_index = 0;    dev_index = verbose_device_search("0");    return 0;}
I get the following error undefined reference to 'verbose_device_search' and This is my makefile


CC=gccCFLAGS= -O0 -c -WallLDFLAGS= SOURCES=$ fm.cOBJECTS=$(SOURCES:.c=.o)EXECUTABLE=fmall: $(TASKMAP) $(SOURCES) $(EXECUTABLE)$(EXECUTABLE): $(OBJECTS)     $(CC) $(LDFLAGS) $(OBJECTS) -o $@ -lm.c.o:    $(CC) $(CFLAGS) $< -lm -o $@clean:     rm -fr $(OBJECTS) $(EXECUTABLE)
can someone put me on track about this problem?

Comment on Using a direct sampling enabled Airspy as a Panadapter for a Yaesu FTDX-5000 by Alex

Hi Tim, I just bought an used AIRSPY HF+ to use with my FTDX5000, my idea is to populate my band map during contests in CW. Do you have any tip how can I do that? maybe using the IF out or just using a secondary antenna for that? I’m afraid to burn it out when I tx.

Any tip would be much appreciated.

thanks in advance.

Thanks for your quick and useful comments! Learnt a bit more – never would have thought about the relation between the usb and the 2832.

Looking at the HAT in your link, I would guess that it is using SPI since the demodulation chip used (Sony CXD2880) supports SPI ( ref: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/media/dvb-frontends/cxd2880 ), maybe it is being clocked a bit faster. The good thing about digital TV is that is is designed to work in harsh RF environments, there is a lot of data redundancy used in transmissions. But placing an SDR on a HAT just seems like a bad place to me.

Нужна помощь, добавил в папку с программой сканер, добавил строку из Magicline.txt в Plugins.xml, в SDR сканер есть, а кнопки скан нет, в чем причина. SDR win 7 pro x64.
