Hey Jim, NETROM works fairly well with Linux's native AX.25 stack and I've documented some of it here: http://www.trinityos.com/HAM/CentosDigitalModes/hampacketizing-centos.html#10b.NetROM-routing It'

Hello Stewart, "sudo" prompts you to for YOUR password but "su" prompts for the root user's password. If the root password isn't set, you'll never be able to successfully use "su". If you want to be r

Here is the other response from SCS. I hope they reconsider in the future but for now, it's very difficult to complain about free. :-) -- Thank you for your inquiry. Currently there is no plan to rele

Not sure if people saw this but SCS has released a program to monitor Pactor 1/2/3 transmissions even with B2F/LZHUF-compressed messages for the Raspberry Pi: https://www.p4dragon.com/en/PMON.html I'v

Swap *partitions* are NOT required on Raspbian as it uses a in-file system swap *file* for this use: https://raspberrypi.stackexchange.com/questions/70/how-to-set-up-swap-space Btw, as mentioned elsew

Hello James, While that looks like a very nice case, there is ZERO chance I'm going to buy a $70 case for a $35 computer. Btw, there are other aluminum heatsink cases out there but this is the first o

Hey Larry, Thanks for the comprehensive post! I've been thinking of buying one of these units too but the use of the I2S pin is a killer for me as I need that bus for the FePi HATT. So, I guess I'm ba

The color issue with Raspbian Buster is resolved in Direwolf 1.6 which is currently in the DEV branch. --David KI6ZHD \

For supporting two radios, you can use this stereo input/output sound device which uses the I2S bus: https://fe-pi.com/products/fe-pi-audio-z-v2 --David KI6ZHD

You cannot use a TNC-Pi and Direwolf together as they do the same basic modem functionality. Putting it another way, the PTT functionality on a TNC-Pi is used by the TNC-Pi's onboard microcontroller O

I've had good success with the FePi using the I2S bus vs. the somewhat quirky Rpi USB bus with Direwolf. I can't see why WSJT or Fldigi wouldn't work equally well. --David KI6ZHD

Well.. there might be one difference. In recent times, the compiling of Fldigi needed more than the 1GB of RAM or the build would fail. The solution here was to create a little swap space to get it ov

The Signalink will only do audio.. Rig control is not supported. The /dev/ttyACM0 interface is the serial port built into the Raspberry Pi itself, used by the bluetooth serial support by default. As t

Hello Vince, There are lots of great guides out there on the Internet but you'll have to piece things together for your specific goals. For example, I've written a doc which should get you going on so

I never recommend user's to re-use the system's built-in soundcard as OS updates always seem to mess with their settings. Specifically, after updates, you can have your OS system notification sounds s

Yes.. it should work fine though I would recommend: - Connect the USB sound device via a POWERED USB hub. - Depending on the radio you have, consider also setting up Rig control via a serial port. Thi

Hello Mike, I recently updated my Raspberry Pi Packet document to cover the Fe-Pi both in terms of why it's superior to say a CM119 Syba USB-based soundcard but also to cover it's rather complex mixer

Heads up on the "E type" USB-C cables and the Raspberry Pi 4. Sounds like work arounds are available though: https://hardware.slashdot.org/story/19/07/09/1934205/raspberry-pi-admits-to-faulty-usb-c-de

Please don't hijack an existing email thread like this. Please create a new email thread with the world "sdrangel" in the subject so search engines can find it, etc. --David KI6ZHD

Hello Carlos, John, This seems to be a missing package in Buster. Looking closer: $ dpkg -l | grep ncurses ii libncurses-dev:armhf 6.1+20181013-2 armhf developer's libraries for ncurses ii libncurses5
