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.

Hi John and all,
I have tried everything listed above on both a Pi3 and Pi4. I can not see the sound card or the gps or even the sensor data. Can someone do a new step by step or better still a video. Maybe just a description of the kernel modules, dkms system, what is the udrc module used for and where to get it. I am interested making a portable SOTA station running FT8 and JS8CALL maybe using flrig for rig control. 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. 73 - Frank - K0FEI

If no-one has any input I will package up my DRAWS for a return. It's a might expensive GPS hat at this point.

Copper PCB RFI Top for DRAWS Case
K4KDR <scott23192@...>
If anyone selects the excellent Pi/DRAWS case from C4Labs:
https://www.c4labs.com/product/nwdrpi-2-for-raspberry-pi-3b-3b-2b-b-and-drawstm-digital-radio-amateur-workstation-version-2-hat/
... and would like to add a top to help guard against RFI (as demonstrated on YouTube by KM4ACK: https://www.youtube.com/watch?v=QZqh_Rc1s9s&t=7s), I just wanted to share that in addition to aluminum, a spare piece of copper PCB material can be fabricated into a decent top.
73!

Re: no transmit

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 /Basil Rob Lapham <ke6jus@roadrunner.com> writes:

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

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

I've only had my DRAWS board for a day, but did have success running the PAT Winlink client (thanks to the YouTube videos by KM4ACK) over 2m ax25 packet. I will get around to testing the HF modes but just haven't gotten there yet. The PAT software is at: ... and by coincidence, I'm also running the FT857d & a Pi3B+.

Re: Undulating transmit audio in HF programs
#draws
Over the air testing revealed that what I was seeing here is mirrored over 200 miles away, so it is not likely a local RFI issue on RX here. Then, I hooked up an external high quality sound card via USB and an external radio interface which keys PTT by USB serial. Clean audio out using FLDIGI. Clean reception locally, and clean reception verified by the remote station.

Re: [udrc] UDRC-II squelch on the Yaesu FT-897D → Resolved, DRAWS does *not* require this

Do I need a pull-up on the SQL lines like I did for the UDRC-II in orderWell, I tried it at first with my FT-897D, got no audio, then tried switching to an Icom IC-706MkIIG… still no joy. I was using arecord/aplay and netcat for testing. I have a Pi 3 with a UDRC-II board as well, which I had previously used with the Icom set for packet radio, so *knew* it worked. This is a completely separate computer, so I shut down the Pi I had the DRAWS on, put it to one side, and plugged the UDRC-II equipped Pi, plugging it into the same radio and power supply with the same cables. Bingo… I had audio, badly distorted, but some tweaks in alsamixer, and I had Triple M Brisbane's calling of the football coming through clear via the UDRC-II. I swapped back to the other Pi with the DRAWS… Comparing the mixer settings, the UDRC-II had the ADC Fine Gain Adjust (ADCFGA) turned off, whereas the DRAWS had them turned on. Soon as I turned those off, I got audio. Swapping back to the FT-897D, it worked there too. No removal of SQL pins or pull-ups necessary, I had audio from both the set directly, and audio from my netbook. I didn't try watching the SQL pin to see if I could detect squelch… that'll be another day. So executive summary: - There is no pull-up or modification necessary with the FT-897D, it worked out-of-the-box with the supplied cables as-is. - Initially I had no audio at all, this was due to ADCFGA being turned on, audio came through when this was turned off. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

Undulating transmit audio in HF programs
#draws
DRAWS image Beta13
I am getting output audio which undulates when using either FLDIGI or JS8Call (or even when just using the TUNE button in FLDIGI). Has anyone run across this? My draws-manager has the other radio port OFF and I have set TX audio levels based on the mW p-p value of my radio (60). Receive audio on the Left radio port is great and decodes like a champ. Receive audio when enabling and using the Right radio port is a very very low level. It's so low FLDIGI will not show a waterfall with the lower limit set to -20 in the program. the same audio levels were used on the Right port as the left port.

Re: no PTT with FT857D, DRAWS HAT and 6 pin miniDIN cable
I am not where I can look right now, but seem to recall WSJT (FT8) does not implement GPIO PTT, so you have to use CAT through hamlib or VOX. Fldigi has a setting for GPIO PTT on a tab beyond the CAT setup.

no PTT with FT857D, DRAWS HAT and 6 pin miniDIN cable
wa9pyh@...
I am using DRAWS software version "DRAWS_BETA13" from May 7, 2019. I connected to DRAWS MANAGER and set the receive & transmit levels there. I am using a single 6 pin miniDIN cable plugged into the left connector and have both transmit & receive audio working properly. But I have no PTT. If I push the mic button on the rig I can transmit the tones. I am using the DIG mode on the rig. I have tried every menu selection combination in the config menus for FT8 and FLDIGI and still no PTT. Any help or suggestions are welcome!
