first entry

I like the program, I had a old RB pi 4 and the thing did nothing, so putchaed a screen at aliexpress and it works. had some broblems with the oriantation. now i only need a way to install this on a usb disk and a auto start of the program.

[paulh002]

For autostart use the crontab file and startsdr.sh in the install dir. See the wiki for explanation.

[cnavarro76]

I installed on a rpi 4 running bookworm 12 64 bit, but on band button, I'm only showing 10m, 6m, 4m, 3m, 2m, 70 cm, 23 cm. all ham bands are in the add / delete box, but no button available to select them. How can I include all the buttons to be able to move around the ham bands. Great work

[paulh002]

Only ham bands are shown which are in range of the SDR device. You can see rtlsdt has a range of 24Mhz till 1.7GB. If you want to add a band just click on an existing band where you want to add the band it will add a row. Then press change to update the row.

[cnavarro76]

Their webpage https://www.rtl-sdr.com/rtl-sdr-blog-v-3-dongles-user-guide/ shows that Direct Sampling HF Mode allows you to listen to HF signals between about 500 kHz to 28.8 MHz. is there a way to switch to direct sampling mode o be able to monitor HF bands

[paulh002]

Direct sampling mode can currently not switched on. Have to add it to the settings page of the sdr device. It is already possible to switch on and of some settings. But this settings has multiple options, that I will add later.
I will post here when it is done.

[cnavarro76]

Looking forward to try it. Tried with out any luck to enable it on the sdrberry_setting.cfg file, and on the Setting.cpp file under the sdrberry menu.

[paulh002]

I have updated sdrberry to support the direct sampling option. You can set it in the sdr setting page. Currently it is in de "build" repository. So you have to switch to the "build" repository. See the wiki page to do so. https://github.com/paulh002/sdrberry/wiki/Installing-the-%22build%22-version-of-sdrberry
However there is still an issue with the SoapyRTL driver, which does not report the extended frequency range. You have to change this in the Settinggs.cpp file

Change the 240000 to 300000 in below code and recompile and install the SoapyRTLSDR

SoapySDR::RangeList SoapyRTLSDR::getFrequencyRange(
        const int direction,
        const size_t channel,
        const std::string &name) const
{
    SoapySDR::RangeList results;
    if (name == "RF")
    {
        if (tunerType == RTLSDR_TUNER_E4000) {
            results.push_back(SoapySDR::Range(52000000, 2200000000));
        } else if (tunerType == RTLSDR_TUNER_FC0012) {
            results.push_back(SoapySDR::Range(22000000, 1100000000));
        } else if (tunerType == RTLSDR_TUNER_FC0013) {
            results.push_back(SoapySDR::Range(22000000, 948600000));
        } else {
            results.push_back(SoapySDR::Range(24000000, 1764000000));
        }
    }
    if (name == "CORR")
    {
        results.push_back(SoapySDR::Range(-1000, 1000));
    }
    return results;
}

SoapySDR::RangeList SoapyRTLSDR::getFrequencyRange(
        const int direction,
        const size_t channel,
        const std::string &name) const
{
    SoapySDR::RangeList results;
    if (name == "RF")
    {
        if (tunerType == RTLSDR_TUNER_E4000) {
            results.push_back(SoapySDR::Range(52000000, 2200000000));
        } else if (tunerType == RTLSDR_TUNER_FC0012) {
            results.push_back(SoapySDR::Range(22000000, 1100000000));
        } else if (tunerType == RTLSDR_TUNER_FC0013) {
            results.push_back(SoapySDR::Range(22000000, 948600000));
        } else {
            results.push_back(SoapySDR::Range(300000, 1764000000));
        }
    }
    if (name == "CORR")
    {
        results.push_back(SoapySDR::Range(-1000, 1000));
    }
    return results;
}

thank you very much for making the changes available so quick!! where can i find the setting.cpp file? under the SoapyRTLSDR directory or under the sdrberry directory?

[cnavarro76]

I have RTL-SDR V3, the SoapyRTL version I have is a bit different, not sure if tat makes a difference. This is what shows on the installed version in my machine.

SoapySDR::RangeList SoapyRTLSDR::getFrequencyRange(
const int direction,
const size_t channel,
const std::string &name) const
{
SoapySDR::RangeList results;
char manufact[256] = {0};
char product[256] = {0};

// Get manufact and product USB strings to detect RTL-SDR Blog V4 model
rtlsdr_get_usb_strings(dev, manufact, product, NULL);

if (name == "RF")
{
    if (tunerType == RTLSDR_TUNER_E4000) {
        results.push_back(SoapySDR::Range(52000000, 2200000000));
    } else if (tunerType == RTLSDR_TUNER_FC0012) {
        results.push_back(SoapySDR::Range(22000000, 1100000000));
    } else if (tunerType == RTLSDR_TUNER_FC0013) {
        results.push_back(SoapySDR::Range(22000000, 948600000));
    // The RTL-SDR Blog V4 can tune down to 0 MHz (in reality ~300 kHz) because of the built in upconverter.
    } else if (tunerType == RTLSDR_TUNER_R828D && strcmp(manufact, "RTLSDRBlog") == 0 && strcmp(product, "Blog V4") == 0) {
        results.push_back(SoapySDR::Range(0, 1764000000));
    } else {
        results.push_back(SoapySDR::Range(300000, 1764000000));
    }
}
if (name == "CORR")
{
    results.push_back(SoapySDR::Range(-1000, 1000));
}
return results;

}

Tried it all, installed from fresh start from the build, changed the Settings.cpp file under SoapyRTLSDR, changed the direct sampling from 0 to 2 from the sdr menu in sdr berry. still not enabling the direct sampling.

[paulh002]

Can you set the vfo to lower frequencies? Maybe provide a screenshot or picture

[paulh002]

That should be ok. Then build and install the SoapyRTL driver did you do that? cd build make sudo make install sudo ldconfig Op wo 25 jun 2025 om 22:13 schreef Carlos N ***@***.***>:

[cnavarro76]

and No, it does not allow me to get lower than 23.999 mhz

[paulh002]

I don't know which version you are using.
But there is a request for SoapyRTL to fix this see pothosware/SoapyRTLSDR#64
But this request is not yet approved.
An option is that I fork SoapyRTL and add the change I will try. I let you know

[paulh002]

I creates a fork you can try the following steps:
first remove or move the old SoapyRTLSDR

mv SoapyRTLSDR SoapyRTLSDR.bak
git clone https://github.com/paulh002/SoapyRTLSDR
cd SoapyRTLSDR
mkdir build
cd build
cmake ..
make
sudo make install

[cnavarro76]

Thanks a lot, that worked like a sharm!!!

[paulh002]

Great, enjoy
