Not really an issue but i would love to see some more demos, things like AM, SSB, NFM demod / mod.

Thanks

Steps reproduce:

• Load the file: Pothos Flow simple FM radio demod failed!
• click activate:
• in the message window in appear the errore / exceptions

Environment:

• Windows 10 Enterprise N LTSC 64-bit 1809
• Pothos Flow v0.8.0-PothosSDR-2021.07.25-vc16-x64 (installed)
• SDRplay_RSP_API-Windows-3.09.exe (installed, to fix SDRplay service error )

Hardware:

• Intel NUC i7 10710u / 32GB RAM
• RTL-SDR v4 USBstick receiver

I downloaded the Simple _FM_demod demo but Pothos won't open it saying that it is
invalid. You should probably fix it or remove it.

I was trying to recreate & experiment with the Frequency Xlating FIR Filter demo - the application I want to create needs to use that block.

When I drop that block onto the graphing area to instantiate the Xlating FIR Filter, the title in the box is red and the following error is shown in the Properties Panel:

FrequencyXlatingFIRFilter0::eval(..) Exception: ProxyBlockEval factory(/gr/filter/freq_xlating_fir_filter) -> {Object Convert Error: Pothos::Object::convert(): doesnt support int to class std::vector <class std::complex, class std::allocator <class std::complex > >}

The file I used for my install is: PothosSDR-2016.01.29-vc14-x64

I'm thinking that this might mean that I need to install the GNURadio suite.

Any help would be great!
Thanks,
Jim D

Once opening the examples, I'm getting the following error message:

Hello everyone and happy new year!!!

I am trying to get the simple_fm_demod demo to work using the LimeSDR on Windows 8.1.

But all I can get is noise as you can see in the screenshot.

This is my message log:

From the wiki I see the following

Other hardware should work, however, sample rates and frontend gain may need to be fiddled with.

What would be a sample rate better suited for the LimeSDR? Now the example sample rate is 1.1025e6

I pulled the demos yesterday (6262ad9) and tried the modem0 example,

First, It doesn't transmit all of the time when I type something. Second, I don't see a signal transmitted. Third, I don't see any signal received.

I'm using a Lime SDR Mini and Pothos Flow v0.7.0-PothosSDR-2018.11.04-vc14-x64. I updated the FTDI drivers for the Lime SDR and reprogrammed it with the Lime Suite software that came with the PothosSDR I downloaded.
