Re: Why not use CUDA cores?

I have not looked at CUDA for several years but did work on the CUDA code for the DFC code running on a Jetson SBC. One of the early problems was that the amount of time taken copying the buffer to and from the GPU made the speed of the CUDA FFT not worthwhile compared with using FFTW. Especially as...

Re: How to skip Auto Discover Routine ?

You cannot disable completely the auto discovery. However, you can speed up discovery by disabling specific protocol discovery by clicking on the Protocol button on the discovery window and selecting which protocols to use. Why? Because it is designed to be able to easily work with multiple radios. ...

Re: 7000DLE Ethernet board type?

Sorry after writing the previous I realised it is protocol 1 and not 2. Ghpsdr has not been updated recently so does not have the Orion 2 defined. The defines in linHPSDR are: #define OLD_DEVICE_METIS 0 #define OLD_DEVICE_HERMES 1 #define OLD_DEVICE_GRIFFIN 2 #define OLD_DEVICE_ANGELIA 4 #define OLD...

Re: 7000DLE Ethernet board type?

Ghpsdr only supports protocol 1. The device types are different in protocol 2. I think the protocol 2 types are in the protocol 2 document.

Re: New install on new Kubuntu

The code was built for Raspian which is running in 32 bit mode. If you want to run on Kubuntu which is running the system in 64 bit mode you will have to recompile both pihpsdr and wdsp on that system.

Re: Homebrewed PiHpsdr

Can you change start_pihpsdr.sh to "pihpsdr >log 2>&1". Run piHPSDR and then send me the log file.

Re: Homebrewed PiHpsdr

The power symbol indicates that the RPi has detected that the voltage level is low and as a result slows the clock on the RPi. This would indicate that you need a larger power supply. The recommended minimum for the RPi3 is 2.5amp.

Re: Asus Tinker Board

The avahi-daemon is not installed by default. You can either install it or the simpler solution is to use a static IP address.

Re: Asus Tinker Board

You can rotate the display but creating the file .xsessionrc in your home directory containing the following:

#!/bin/sh
xrandr --output DSI-1 --rotate inverted


Then reboot the system.

Hi Mike,

I have updated the install document to say to use dd or Win32DiskImager to create the bootable image. I have also changed the .build instruction for wiringPi to be sudo ./build.

Re: Power Supply for 8000DLE

I would suggest getting something a little bigger than 35A so there is some head room. I have a 40 Amp linear supply (not Astron) and that has been working with no problems.
