Re: rpi5 and wsjt-x
I have the same problem - I have a working RPI-5 with DigiRig and WSJT-X + Winlogger on my Mac and the KX3+DigiRig+WSJT-X works 100% transmit and receive. When i move the to exact same configuration (unplug USB from MacStudio - Plug USB into RPi5) , FT8 decoding and all features TX etc. All work except NO transmit audio comes out of mic cable . ?I run the KX3 in upper sideband mode (USB) and have used RTS keying and there is no audio coming out the DigiRig into the microphone jack. Running in data mode makes no difference. I tried ALSA mixer control but it’s primitive and offers no ability to make the DigiRig chipset open up Xmit audio for the mic jack cable.?
Any ideas
thanks

KX3 - WSJT-X with Raspberry Pi 5 and DigiRig sound card (CP102 and CM108 audio chip) fails TX audio
I have working KX3 + DigiRig with my Maclogger program and WsJTX on my Mac computer.
When I setup my new RP5 with DigiRig the audio decodes on FT 8 (in WSJT-X) but when I key the KX3 in USB mode ( audio modulation ) the radio will key but it seems the transmit audio goes out through the HDMI driver and out its speakers instead of into the mic jack.?
I used the ALSA tools and LSUSB command and the Cp102 + CM108 audio chip show up correctly. I cannot get the CM108 to take priority over outputting the FT8 audio which goes to the HDMI audio on my LED monitor. The apparent rule of muting all output channels seems to apply to my trying to get audio out and into the mic jack on the KX3. Since this a working system I can only conclude I am missing some tool to change the priority of increasing the driver ahead of the HDMI audio driver in the Raspberry Pi 5 OS. Anyone have any suggestions how to get the settings right. I have been through several good articles on the RPi site by Philips and USB audio cards by Lady Ada to no avail. This has to be entwined with the fact the analog headphone port went away with the advent of the RPi5 and I cannot find a tool as the ALSA mixer won’t allow me to change the audio stream. Thanks for reading this Best regards John K3GO |

Has Anyone Installed SDR++ on a Raspberry pi that has the Dabian Bookworm OS?
?
I've run it from the command line interface using
?
sudo apt install ./sdrpp_debian_bookworm_amd64.deb
?
Ive got the SDR++ icon in my graphic user interface, but no amount of clicking on it will result in a launch of the package.
?
?
Any help:?

Thanks Terry KG0DU

Re: Power Pi 4 or 5 from 12 volts
开云体育Mats,
Thanks for the chuckle!? I shared it with my hockey-intense sons and wife and they laughed, too!
The shields always present a challenge unless you are fine with a 3D printed case with no RF shielding.? More than once, I have used a large generic RPi metal case and drilled and cut openings.? ?I have also resorted to metal boxes and short
pigtails to bulkhead connectors for essential external connections.? I also have one 19 inch 1U rack for five RPis complete with an SD card jack and pigtail for each on the panel.? I am going to rework it for several dedicated RPis.

The problem with most shields are no boxes working for you and then you end up in a mess.

Re: Power Pi 4 or 5 from 12 volts
开云体育Mats,
Off topic:
My sons are asking me if you are the "Mats Sundin" who played ice hockey in the National Hockey League here in the U.S.?
On topic:??
I use several different 9-16 V to 5 V converters and USB A distribution blocks with USB A to USB "x" type cords often with 90 degree plugs to easily fit in small cramped spaces with bending cables.??
I tend to avoid using RPi shields for power alone, preferring to make the header available for other functions as needed.
The other benefit of this approach is that my backup power can all be 12-15 V with most of it consisting of LiFePo4 batteries between 12.8-14.6 V.? This greatly simplifies things.
Thanks!
