I don't know what directory I am in or how it changed. All these commands worked before.

Are u in correct directory to run these commands? Just a thought 73 Jerry

Subject: [RaspberryPi-4-HamRadio] Command not found

 

I don't know what I've done but my pi doesn't seem to recognize any commands. They all come aback with " bash: command not found"

How can I fix this? I've run update and upgrade and rebooted.

Thanks

My guess is that your PATH environment variable was removed.

If you type echo $PATH (echo is built into the shell), you should get something like
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:


When you type in a command, BASH looks to see if the command is built in. If not, it then looks though the various paths until it finds the command.

I'm having to "bail out" right now to go meet some folks, but check out the following.

https://unix.stackexchange.com/questions/227989/complete-view-of-where-the-path-variable-is-set-in-bash

(be care of the possible line breaks)

and in your home directory is a file called .profile Note it has the "dot" in front of the file name. The dot keeps the file from being displayed unless you want by adding the -a option to ls.


The commands are likely there, but just not accessible because the path. So, while you are looking around, try

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:

and then

so you can at least look around.

Never mind. They aren’t tnc-pi 2’s so it doesn’t matter. They won’t work for my project. Thanks for responding

Have you measured rfi for this ps?  I have a similar unit(shipped by a popular Pi kit supplier) that creates a lot of 20m hash on my 7610.  My fix was to use the Anker dc battery bank recharger used for my iphone.  It will run my pi for a few days..an acceptable solution until I find a suitable regulated dc ps.

Re: Unbootable SD Cards

Bradley Davy
 

I had an SD card failure not long after setting up my first Pi 3B. Reimaged and its worked ever since. I’ve had a couple instances where I could not get into the Pi via SSH due to network or update errors and had to unplug the power to move it to plug into a TV. On one occasion I noticed the green LED was periodically on, which I believe indicates its reading or writing to the SD card. Now I try to make sure the green LED is not lit before pulling the power. No SD card failure since I’ve adopted this practice.

I've had 2 SD card 64 G died on me using a Docker Power Buck converter. I've got a replacement coming to me. The 5 v plug works but not the 12. Not sure if defective or my bad luck with these SD cards. Plus another Metal case with a fan also killed an SD card. Heat??

Low voltage then build your own DC cable plus you can cut it to a decent length and set the power supply to 5.3 volts.



Re: Unbootable SD Cards

Bernard Littau
 

I am similarly mystified but have experienced SD card failure on the RPi myself.  I attribute this, perhaps mistaken, on cheap SD cards.  Twice now on SD cards shipped with the RPi as a kit.  

I believe, at this point, SD cards are like toasters: an appliance, you get what you pay for. Commodity item.

Re: Unbootable SD Cards

I don't know what corruption issue you are talking about. I have been using SD cards for years with no issues.  You also don't mention the power problem of supplying power to the drive either through the Pi or with a different power supply.

But to each their own. If you are comfortable with your setup that is great.

Dump the SD cards and go to small SSD drives instead.  You can get 240/256 Gb drives for less than $40 and a USB case for them is another $10.  You'll have more room and won't have the corruption issue.
Note: Depending on the version of your Pi, you may still need a small "bootstrap" SD card as not all Pi's can boot from a SSD. That card will only be read at boot and does not experience the corruption issue per my experience.
I've had good results with the Team Group 256 Gb SSD at $29.99 from Newegg or Micro Center.

John, So maybe mid-June we may see a product available for us out here in the real world? hehe

Hi,

Let me clarify a few things... The new TNc-pi will have the same footprint as the old one and will have the same 40 pin header.  It is essentially the same product.  The main difference is that it will be mostly surface mount parts to facilitate manufacturing.  

I am currently in Cozumel but before I left I completed the PC board design and sent it off to China to get prototypes.  I thought I did that soon enough to beat Chinese New year, but I guess everyone else was doing the same thing.  They should arrive by the time I return to NY in mid February.  At that point I will build a couple of units and test them to make sure the board design is solid.   Then they can be released to manufacturing.

All the TNC-Pi2 kits and completed boards are gone for good.  Unless you can find someone who is willing to sell you two of theirs, they are no longer available.  One of the nail in the coffin issues was the PIC chip that was programmed with the KISS software is no longer available, so this prevents anyone else from taking up where John left off.

However, work is being done to have MFJ start building and selling them, but in a slightly different format.  One of the last things John Hansen did was redesign the board to use newer chips and make them all surface mounted.  This was to make is easier to automate manufacture.

This means, no more kits.  *IF* MFJ decides to go with this, they will all be assembled and tested.  I say *IF* because John has submitted his design to MFJ but they have not yet said if they will take up building the boards.

I'm hopeful that they will start soon.  Until then, all we can do is wait.

I have experimented with Direwolf, and while it is easy to get configured, and it does work pretty well, I have found it to be unreliable and needs to be restarted or the Raspberry Pi rebooted frequently or Direwolf will just hang.  Perhaps there is more testing I can do to figure this out, but for now I'm gonna wait and see what happens with the new TNC-Pi.

Re: GPS looses FIX when HDMI is in use...

Chris Weiss KJ7GST
 

According to this article, the interference is affected by the resolution of the HDMI output. If you are using the HDMI for a display, you could try changing the screen resolution. There are some other things to try at the bottom of the article.
 
Supposedly, this will be fixed in a firmware update (that would be included in the base Raspbian distribution), but I can't find any information about if/when that will be released.
