I just recently joined this group. I'm new to the Raspberry Pi and actually new to Linux. My original purpose for the Ras[berry Pi was to use it as a spectrum monitor for the IF of microwave transverters. This would hopefully take one unknown (the frequency) out of the picture when trying to peak a signal with a dish antenna. My laptop is an energy hog and is also bulky. Not very conducive to microwave hilltopping operations. I got a Raspberry Pi 4B. I found these instructions for installation of a program called Freqshow on the Adafruit website: https://learn.adafruit.com/freq-show-raspberry-pi-rtl-sdr-scanner/installation This seems ideal and exactly what I want. The only problem right now is that the Adafruit 3.5 inch PiTFT display is nowhere to be found. Everyone who carries them is out of them. So that project is on the back burner right now. I successfully installed the OS for the Raspberry Pi on a 64 Gb micro-SD card. Then I found this site: https://hamprojects.wordpress.com/2020/09/06/raspberry-pi-for-ham-radio/ So far, I have successfully installed GNU Radio, GQRX, RTL-SDR, FLDIGI, FLRIG, WSJTX , JS8CALL and QSSTV on the Pi using the instructions there. I think it's successful because FLRIG connects OK to my FT897D using a CT62 USB cable.It seems more limited than what the webpage shows with installation instructions shows. I am only able to change frequency and mode of the radio, For some reason I have no controls shown for volume, squelch, noise reduction, etc. Maybe these aren't available for that rig in that program. GQRX seems to work OK with the SDR dongles I have, except when I use it with the FUNCube dongle, the mouse locks up and I have to unplug the dongle to get mouse use back again. I'm not sure why that is, either. It works fine with RTL-SDR Blog V3 and Airspy Discovery HF+ dongles. Hopefully some day the 3.5 inch PiTFT displays will be available again and I can start playing around with using that on the Raspberry Pi. 73, Zack W9SZ Virus-free.www.avast.com

Question for any fldigi / flrig gurus. I installed both on a new Raspberry Pi 5 using the “add /remove software “ available in the GUI. Noticed that my FT-710 wasn’t supported, further investigation shows that I am running version 1.4.7 of flrig. I believe the latest is 2.2 - so I tried : sudo apt-get -y flrig. The system tells me that I already have the latest version 1.4.7–1. ? am I correct that there’s a more recent version. Also, I posted a question about this on facebook and was told the FT-710 was not supported on any version of flrig - is this correct? If it is supported, how do I get the latest version. Please keep in mind I am a Pi novice..... Any guidance would be greatly appreciated

Using an 8GB pi-5 with NVme & SD card Problem with network?? Can someone figure out what is wrong from this, the only clue I found? If I hold down the shift key and use key to reformat the SD card and then let it boot it works FB. However, after I shut down the Pi and later boot it it can't find the internet (although the terminal does download very slowly). OS is Bookworm 64.

The RWS project allows anyone using an HF radio and a computer to access the internet from anywhere if needed, either because of an emergency or if you simply go somewhere that doesn't have internet. The current implementation of the server uses the VARA modem, which is free, though the uncapped speed version costs $70. (But, if you call CQ and a server with a licensed copy of VARA answers, there won't be any restrictions, and vice versa for any unlicensed server hosters) The server has a lot of built-in commands which allow you to: View a website (either in plain text or raw HTML) Perform a quick search Get the weather forecast for a given city + state Download a given URL (download is encoded into base64 to allow download through text, instructions for how to decode are given alongside the download) View and create threads and comments in the community section of the GitHub of the project Print server info, logs, and global active servers I've read Part 97 of the FCC and I've made sure my server is fully legal. My end goal for the project is to have hundreds or thousands of servers hosted around the world, which would allow coverage for almost everyone on Earth. The server and instructions for how to host your own are listed at the GitHub: https://github.com/Glitch31415/rws To connect to a server, make sure you have VARA and VarAC installed. Once those are installed and working correctly, go to 14.110 MHz USB and call CQ. (Both 500 Hz and 2300 Hz bandwidths are supported.) Wait for at least 2 minutes. If a server has heard you, it will call back and try to connect with you. The list of commands and other instructions are sent once you're connected. I need testers and server hosters to properly see if the server will work correctly in the real world! If you aren't using your radio at the moment, and if you have a computer connected to the radio, you can get the server running in 10 minutes and just let it sit in the background, waiting for a connection, with no further hassle needed. If you want an external helper for dealing with the downloads and base64, KC3VPB has created a helper that can decode base64 automatically and save it to a file. https://github.com/Caleb-J773/rws-tools-release/releases For more info or if you need help, email me: jpradiophone@...

Good morning all, I have the Pi 3 Model B using Raspbian version Bullseye. For some reason, my desktop screen has a white line on the left of the screen. It's about 2 inches wide and travels vertically down the monitor. When I restart the Pi the desktop image is full screen but as the restart progresses the white edge appears. He is what I have tried: Right-click on the desktop and click on appearance settings. Under desktop layout indicates the centre image on the screen. I have tried all settings but same issue with the white section on the left side of the screen. Under the menu bar, I have changed the position to the top. The desktop picture is now full screen but not the white section is at the top of the screen and it cuts off the top half of the icons. In the menu bar setting, I have also changed the size and still have the same issue. Under defaults, I have changed large, medium and small screens and still have issues with the white-out section of the screen. At a loss at this moment as to what to check. Thanks Mike VE9KK

I would like to implement a RPi NAS. I have a WD NAS that could fail at any time (10 years old). I have seen one Instructable about making an RPi5 NAS but it was rather vague and required printing a 3D case and I have no access to 3D printing in this area of 200K population! I just purchase a RPi4B NAS kit on Amazon: https://www.amazon.com/dp/B0B6V66PRB It consists of a metal enclosure with a RPi heat sink and fan and a SSD adapter card. I expected the instructions to at least suggest a/some Linux NAS programs to use but the instructions went into detail about how to enable the pretty flashing LED's and never even mentioned how to set up as a NAS. Are there other hardware setups for NAS? I have only seen the 1 plus the one I found on Amazon but can not imagine that there are not a lot of them. With all of that said, can anyone recommend a good Linux NAS program, preferably GUI but not a deal breaker. I use my WD NAS for storing all of my files including all the ham radio and microcontroller files and programs and would like to get that backed up and moved over to another system hence the request. Thank you. Jim Pruitt

I am pondering using a Raspberry PI for a repeater controller. Until now I’ve been a firmware bare-metal repeater controller builder. A local repeater has a problem in that people keep leaving their APRS beacons turned on and dialing over to the repeater. The APRS beacons on top of other people once in a while. It beacons when nobody is talking as well but the PL is silencing it I presume. It would be a really cool feature if the controller could recognize the APRS packet on the repeater input and announce the callsign of the sender, with or without mentioning their ancestry. Do any of the software packages for the Raspberry PI do this? With or without an external TNC? Thanks! KA2DEW- Tadd https://qrz.com/db/ka2dew

Using a Pi-5 and 64 bit Bookworm. Seems OK booting on SD card. Internet extremely slow booting on SSD. Several attempts to make it work. Latest was using SD card and updating it. Then write SD to SSD. Switched to boot SSD. Chromium seems to make it fail; it gives a timeout. Then rebooting from SD card lets Chromium work. I use the Pineberry BOT to connect the SSD. SSD is a Fikwot FN501pro. Any ideas what I should do?

These changes to the Python GPIO library functions have me stumped. I keep looking for documentation, but I haven't found the correct place. I am trying to read and input pin. I'm interested in edge detection, and possibly debounced input. I was previously able to do something like this: GPIO.add_event_detect(door_switch, GPIO.FALLING, bouncetime = 500) Using GPIOD I can read the input, but it isn't elegant to build loops to check if there was a bounced input. If someone could point me toward better documentation it would be greatly appreciated. Arnold KQ6DI

Just got a Pi5 installed Wsjt-x on it only to find that the min and max buttons are missing from the top right corner. Same with Jtdx. How do I fix it. No problem with JS8. Philip g7jur
