Jon, there is a unsubscribe and mute topic button on the bottom of every email you receive if you were not aware how to properly exit the room. 

Excuse typos and brevity, sent from a mobile device.

I'm done with this group

Vince,

Give these commands a try:

lscpu
cpuinfo
cat /proc/cpuinfo
lshw

If you need to install any of those, try something like this

Apt-get update
apt-get <package name>

Best regards,

A few recommendations to run from the command line:

    free
      - This will show the amount of RAM populated, used (for programs and cache)

   cat /proc/cpuinfo
      - This will list the type and number of CPU cores

   bash <(wget -q -O - "http://www.trinityos.com/HAM/CentosDigitalModes/RPi/usr/local/bin/review-rpi-cpu.sh")
      - This will download a script I put together to show lots of additional details specific to the Raspberry Pi


For different Rpi pictures, showing the differences, use a Internet search of "pictures of all raspberry pi models" will bring up many examples

Hello Group

I have a new to me Pi board. How do I check the specs of a RPi Board on the command line. I.E. Cpu, mem?

On top of the RPi board it just notes it's a Raspberry Pi 4B but does not say the amount of memory? Also, is there a pictorial (picture of different RPi's) displaying the different versions (Component layouts)?  TIA

"Galvin Manufacturing Corporation" (1928–1947)

Btw, for what it's worth, I've updated my Rpi amateur radio doc to include various specs and details of the new board as well a new feature sections like adding a variable speed fan, light sensor and IR transmitter support, improved security hardening steps, etc.

Hello Everyone,

If you haven't already heard, the Raspberry Pi Foundation has released a new Raspberry Pi Zero named the "Zero 2 W".  It essentially is the same as the Zero W but now has a four-core processor similar to the Rpi 3 (not the 3+).  This means we now have a much more modern processor design with four CPU cores instead of one.  This does come at a power consumption cost but it might be possible to disable some of the cores to lower the power down.  Time will tell on what's possible but also being on a newer CPU design, a lot more alternative OSes will become available for this SBC:

That did the trick.  The only change in the documentation is what USB type to select, as Serial + Audio does not exist.  Attached are compiled binary's if any wants it. This turns your TNC-Pi96 into a basic sound card and works with VARA and SoundModem if you want to go that route.  Makes the device even more flexible.  You will need to connect the TNC to your computer via the micro usb port.  I have only tried it on Windows.

Ah, the tyranny of the mobile phone. Unfortunately, it is effectively
relegating serious discussion, which necessarily requires more lengthy
messages, to history's dust bin.

In the same vein, I've been observing that people increasingly fail to add
the "ly" to the adverbs they use. I fear we are becoming less literate over
time...

Very well said. As a former Professor and somewhat new radio guy I whole-heartedly echo Tadd's gentle remarks.

And many thanks

isnt the signalink doing ptt with a vox circuit inside the modem?!?

then you need to crank up the tx level (tx volume)

just an idea from a dumb nut

I am having issues with my Signalink PTT not activating when using QtTerm and QtSoundModem on the Raspberry Pi. QtTerm and QtSoundModem are talking to each other on the Pi but not activating the PTT on the SignaLink. On Windows EasyTerm and Soundmodem activate the PTT. Any idea why it doesn't activate on the Raspberry Pi? Please help.

Why? He only wants to back up his drive to install a new OS. Just spend $70 and buy another drive.

Run gparted and reformat the thumb drive FAT32 before you re-use it. gparted will also rename it.

If you want to take a copy of your Pi herd drive you will need another drive at least as big. Back it up with 'dd if-[existing drive] of=[new drive]'

I would like to generate a backup for my Raspberry Pi-4b prior to upgrading HamPi. My setup uses a hard drive.

I have a 32 GB flash drive now. I used it to try to transfer a backup with an error and it would give an error and limit the file to 4 GB. That file was deleted.

First, I want to change the name of the thumb drive directly. When I try to do that I find I get an error and it doesn't change the name.

Second, can I delete the extra files that where already on the thumb drive (when purchased, I think).

Attached is a screen grab of what happened and what the directory permissions are.

Photo resolution is low hard to make out all the text but I see permissions on changing attributes. You run with sudo?
