Hi John,

I followed your steps exactly,.  The second post was some additional info to show that I could read the EEPROM and thus the hardware was working.

I think there is a  problem that the drivers are not being loaded.

Is there a log file for the image_install script?  Is there anything else I can send to you?

Thanks

Frank,

Between your two emails, I am not sure of your current state.  Did you follow the steps I outlined earlier?

You should be seeing the card.

Hi John,

My results were not successful.

I am using a Pi 4 - 2gb memory with the Buster downloaded today.  I did not turn on anything except to connect to wifi.  After the install I did enable ssh.

Not to put too sharp of a point on it, but Buster and Pi4 have been out just short of two months.  Downloading the stretch Compass gives you something that can not be updated.  Is there any projection when drivers for Buster and Pi 4 will be available or even a downloadable image.

As for the Pi 4 heat problem, just use the PoE HAT between the pi and DRAWS and put a small heat sink on the cpu.  It will not go above 58 C on a fully loaded system.

I did this just yesterday
(from memory - not at system right now)
Download and burn Buster onto SD Card
Let it boot up and update/upgrade

sudo reboot
sudo apt install git build-essential
cd
cd n7nix/config
sudo ./image_install.sh
sudo apt install --fix-broken
sudo reboot

After boot try
aplay -l

Use n7nix scripts to install/config applications.

Re: no transmit #wsjt-x

Basil Gunn
 

Rob,

Verify that transmit is working with the simplest program possible.
Use the measure_deviate.sh script to output a tone on a specific
channel. Assuming you are using the mDin6 connector closest to the gps
SMA connector. If you tune a second radio to the same frequency as the
first you should hear a tone.

cd
cd n7nix/deviation
./measure_deviate.sh -c left

To see the command line parameter options:
./measure_deviate.sh -h

Also send the console output of showudrc.sh

I'm writing an ARDOP transport for paclink-unix that runs on the RPi.
I use ardopc RPi (piardopc) from here:
http://www.cantab.net/users/john.wiseman/Downloads/Beta/

I test that with ARIM from here:
http://www.whitemesa.net/arim/arim.html#inst

Currently for winlink using ARDOP on an RPi you can use PAT or LinBPQ

I think there is also a build shell script in Beta13 for ARDOP, but I have not used it.

Re: ARDOP or software similar to WinLink (HF mail) #winlink

 

I'm not sure if it's included, but there is an open source implementation of ARDOP that can be compiled to run natively on the Pi. Check here: http://www.cantab.net/users/john.wiseman/Documents/ARDOPC.html
