Hello! A very beautiful project. It is surprising that little is known about him. Will there be HPSDR support? And support for external buttons, such as in piHPSDR

[paulh002]

Thanks, it could support HPSDR protocol, Radioberry is based on hpsdr. But currenlty there is no SoapySDR driver for devices like hermeslight and I don't own such a device. But it would be not to difficult to add HPSDR support direct once I have a device I will give it a go. External buttons are supported, right now I use a ESP32 on USB as adapter. It supports optical rotary controler for vfo and mechanical for volume and other items. But this can be extended. It uses CAT interface commands on USB. (also bluetooth is possible)

Thanks a lot for your answer, Paul! I think can try using this console https://github.com/VU2DLE/Radioberry_Console What do you think about this? I have been looking for a program for the Raspberry Pi for a long time, of course everyone knows piHPSDR from g0grx. But it has a very unattractive interface. Ram, VU3RDD made it prettier. https://www.youtube.com/watch?v=0pO9re2Jr84 But your version looks great!

This is how my homemade transceiver looks so far)))

Looks great, I think you can use VU2DLE console. Should not be to difficult to support it. If you check my repositories for VFO ESP32 and ESPControler you can see examples of the controler I made it uses small touchscreen instead of buttons. The SDR tranceiver is it your own design or variation on Hermes Light2? Look very interesting. Problem with radioberry is the availability of the FPGA. So if there are alternatives would be nice. You can check a demo at my youtube channel https://www.youtube.com/watch?v=ycU_IUmV8j4

Interesting video. But I didn’t understand if there is a noise suppressor and impulse noise? NB and NR? And another moment. Nothing is clear on the spectrum analyzer. It is absolutely chaotic, the signal is not visible on it.

There is such a project, from Laurence Barker, the "ODIN" console for PowerSDR. It also has a separate display for buttons and an extended menu. https://github.com/laurencebarker/odin-SDR-console

[paulh002]

No, don't have noise suppression yet, To be implemented. I got some examples to do so. The spectrum analyser need some improvement. You can adjust the gain of the spectrum analyser but the noise floor is quite high. I like the spectrum look of SDR-Console. I would like to make it like that, will do some experiments by adding a low-pass filter to the spectrum analyser to reduce noise in picture.

[UN7RX]

What a pity. Without such functions, the transceiver loses a lot. Digital signal processing, noise and interference suppression for DDC DUC is probably a must-have feature.

I tried installing SDRBerry today. Unfortunately, it doesn't work yet. The first part goes well. The last command takes a very long time to complete. As if I installed half of the Debian repositories))))

./sdrberry/install/install.sh

But then there are problems, here is the block of code.

git clone https://github.com/paulh002/sdrberry  
cd sdrberry  
mkdir build  
chmod +x ../do_cmake.sh  
../do_cmake.sh  
make
sudo make install  

There are problems when trying to compile Please note that the code in this form ../do_cmake.sh does not work for me at all. Only do_cmake.sh or ./do_cmake.sh Either way, it throws an error. Until I got further..

[paulh002]

Error in the readme page. You have to cd info build directory. Also note sdrberry uses framebuffer to write to display. You have to switch of xwindows desktop before starting sdrberry. Just user raspi-config and in System menu switch to console only.

Also I did a lot of updates in dev branch, but need to update installation script for it.

[UN7RX]

Thanks for the reply Paul! I think that the installation option that is now is designed for a well-prepared Linux user. And knowledgeable Raspbian. Unfortunately, I'm not very good at this yet. Therefore, I will not take your time, maybe in time your beautiful software will be installed even by beginners. Installing piHPSDR is very easy and automatic. I'll put either him or Thetis with a hardware console. Good luck, thanks!

[paulh002]

You are right, installation is complicated. There are several way's to make it more easy, like using docker or put all libraries directly in the git repository. Have to thinkt about it. Any way thanks for the interest. But the SDR receiver you build is there any information about it? Looks very good. Any way thanks and see you later 73.

This is a fairly simple device, AD6645 + DAC904, audio codec on WM8731 (but it is not required, it also works fine without it), FPGA EP4CE22E22C8N. The module with FPGA is used ready - so there are fewer problems with the layout of the board. I have a module with EP4CE22F17C8 which is even smaller but has a lot more ports. This allows very good development of the scheme. This idea is taken as a basis. The source codes are open, the Verilog language is also not difficult.. I am an electronics specialist and it is much easier for me to construct this than Linux and C :)

[UN7RX]

Paul, will you continue to develop your program? Or will it not be fast?

[paulh002]

Yes, I am still developing the program. There are some items I am working on currently. 1) Improve soapyradioberry driver transmit still has some issues. 2) support for hermes light2. 3) FT8 transmit. 4) GUI improvement. But I also want to improve installation. Is to complicated currently.

[UN7RX]

Thank you! The most pleasant interface for a 7 inch display for a software transceiver. If you manage to finalize everything, it will be the most popular! Maybe I still have time to put it)))) Good luck to you!

Thanks
