How To Program Yaesu’s FT5DR With Chirp In Linux

For the first time in several years, I was able to go the the 2023 Dayton Hamvention. If you have ever been, it is perhaps the best hamfest there is. If you did go to the Hamvention, did you get your Yaesu hat? I did – as well as my daughter, KC8GRS, and her two kids. It was a great 3 day event with approximately 35,000 hams present. One of my goals was to purchase a Yaesu FT5DR radio.

Bought the FT5DR

So I wanted to pick up a digital radio that supported Yaesu’s System Fusion. After chatting to one of the guys at the Yaesu booth I went straight over to the Ham Radio Outlet booth and bought the Yaesu FT5DR handheld radio. I also bought the RT systems USB-68 cable, but not the software since I don’t really have a Windows computer, except for an old laptop that does dual boot into Windows 7, but I almost always boot into Ubuntu. Since most of my computers are now Linux based, so the software that they provide won’t work anyway. Instead I use the Chirp program for my radios.

CT68 cable not working

After I got home and started looking at my shiny new Yaesu FT5DR, I quickly found out, that Chirp can’t see the CT68 cable! So the first thing I did was open up a terminal window, and issued lsusb to see if Ubuntu can see the device. Sure enough, as you can see in the screenshot below, its there!

But when I type ls /dev/ttyUSB* it doesn’t show as being available as shown below:

My first thought was that I had a defective CT68 cable. But then I remembered that I had my old linux laptop with Windows 7. I was able to put an old version of Chirp on it on the Windows 7 side, and sure enough I was able to program my FT5DR radio. But the old version wouldn’t let me program the radio for digital modes.

Field Day Logging Software For The Raspberry Pi

I have been searching for a Field Day logging program for a couple of years that works on a Raspberry Pi and also works with Winkeyer. A lot of people like CQRlog, but it doesn’t seem to have the “flow” for me when entering QSO’s during Field Day. Another logging program that is used with the Raspberry Pi, is HamRS. It looks like a good choice, however I like to run CW on Field Day and HamRS doesn’t have any support for CW, specifically macros, as well as sending them to Winkeyer.

Just after last year’s Field Day, I stumbled on to FieldDayLogger written by Mike Bridak, K6GTE. He also has a companion program, PyWinKeyer, that works with Winkeyer as well as the CW Macro’s that are part of FDlogger. So this year, I gave FieldDayLogger and PyWinKeyer a try on My Raspberry Pi based Go-Frame.

Field Day logging software for Raspberry Pi

The look and feel is similar to the infamous N3FJP Field Day software but with a different color scheme – its actually easier on the eyes, especially at night. The FieldDayLogger program uses the same keystrokes as the N3FJP software so if you are familiar with N3FJP’s Field Day logging program, the transition to FieldDayLlogger will be a snap. The one down side to the FieldDayLogger software is that it doesn’t support networking, which is fine for my 1E / single transmitter operation.

UPDATE: Michael Bridak has added Multi-station networking support. This is great news! I haven’t tried it, as I only run one transmitter. You can read more about it in his manual on github. Thanks for your hard work and great contribution Michael!

How To Reset MySQL Root Password

The other day I needed to reset the root password for a mysql database because I forgot it (oops!). Fortunately, there is a simple solution to resetting root password in mysql.

he first thing you need to do is login to your server as root. Next,you need to stop mysql with the following command:

/etc/init.d/mysql stop

Once Mysql is stopped, you need to restart it, but in the background with the mysql_safe command like this:

/usr/bin/mysqld_safe –skip-grant-tables &

The & shoves the process into the background. Once MySQL is up and running you will see the following output:

[1] 6831
Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe[6961]: started

You can see the new job number, in this case, [1] has started and the server is running with the process ID of 6831. By using the –skip-grant-tables option you can connect to the MySQL database without a password, which will allow you to change it to a password that you know.

VERY IMPORTANT: You must enter the following commands exactly as shown. Particularly, words in upper case, and having a semi-colon ( ; ) at the end of each command.

OK now we are going to login to the MySQL database with the following command:

mysql –user=root mysql

It will ask you for a password. Just press the [Enter] key.

At the mysql> prompt enter the following:

update user set Password=PASSWORD(‘new-password-here’) WHERE User=’root’;

NOTE: in the above command, you must use single quotes around the new-password-here part. MySQL will return the following:

Query OK, 2 rows affected (0.04 sec)
Rows matched: 2 Changed: 2 Warnings: 0

Next type the following: flush privileges;

And then: exit

Now that the root password has been changed, you need to stop the MySQL server so that you can go back to running a secure MySQL server with password restrictions in place. So you need to bring the MySQL server running in the background into the foreground by typing “fg” and then kill it by pressing “Ctrl+C” afterwards.

Now just start the MySQL server with the following command:

/etc/init.d/mysql start

You now should be able to login to your MySQL server with your new root password by using the following command:

mysql –user=root –pass=new-password

This should let you in to your MySQL server.

Delete Files So Many Days Old in Ubuntu

Recently on one of my Ubuntu servers, I needed to delete files that were older than a week. As a general rule, this is good practice for files that you may need but after a while you won’t need them. In my case, I only needed them for at most, a week. Here is how I did it:

By using Ubuntu’s find command with a few options, will take care of what I need to do. Here is the command that I used:

find /path_to_files/* -type f -mtime +7 -exec rm -rf {} \;

OK, let me explain the syntax of the find command above:
The first part is the path that you want find to search. Wildcards are permitted, as shown in the command above.

The option -type f tells the find command to search for just files (more on this later).
The option -mtime +7 is what sets the number of days old the file needs to be. In this case, we are looking for all files older than 7 days old.

The option -exec lets me pass a command on to a new process that satisfies the find command. In this case, we want to rm -rf which recursively deletes what we want from whatever folder in the specified file path, and forces the operation.

Its very important to make sure that there are spaces between rm -rf, {}, and \; if you get an error, this is the first place to look.

Like I mentioned earlier, the -type f option just deletes files. In my situation I still had a bunch of empty directories that weren’t deleted. The solution to this is, after you have executed the above command and deleted the files, change the option to a -type d and re-run the command. This will delete the directories.

Then just place the find command into cron and set it to regularly run as you like.

How to fix scp: Ambiguous Target Error Solved

Recently I needed to copy a file using scp to another server and encountered the following error: “scp: ambiguous target” In doing some testing I figured out that the space in the file name was the problem. Here is how to handle a file name with a space in it.

I even tried putting the file name in quotes, and that didn’t take care of the ambiguous target error message. For example, I was trying to use the following command:

scp myfile.txt user@192.168.1.100:”/file path with spaces/myfile.txt”

In trying to put the quotations marks in several different places, it still didn’t work. What you need to do is escape the space with a backslash. what is meant by this is that you need to put a backslash in front of every space in the file path name. So the above command then becomes:

scp myfile.txt user@192.168.1.100:”/file\ path\ with\ spaces/myfile.txt”

This takes care of the scp: ambiguous target error message from the command line, but what about running inside a shell script. In that case, you would add two backslashes. So the above command then becomes:

scp myfile.txt user@192.168.1.100:”/file\\ path\\ with\\ spaces/myfile.txt”

How To Find Files In Ubuntu

All too often you need to find a specific file in Ubuntu. When I need to find files in Ubuntu, the “search for Files” tool is usually inadequate for me. So I typically open up the Terminal and use the find command, which can be found to be a bit tricky to use, but powerful.

I typically need to search the entire hard drive for the file I am trying to find. So once in the Terminal, just issue the following command:

sudo find / -name’ xorg.conf’

In this case, we are looking for the file “xorg.conf” and the -name option tells the find command that we are looking for a file name, and the / tells the find command that we want to start at the root.

You can also use wild cards as well. For example. if we want to find all of the .conffiles on our hard drive, just issue the following command:

sudo find / -name ‘*.conf’

Typically issuing this sort of a find command there will be a lot of files scrolling off the screen. So just pipe the find command to the more command like this:

sudo find / -name ‘*.conf’ | more

Then just hit the space bar to view the next screen. Additionally, it is good practice to use single quotes when specifying the files you want to find otherwise the results may become unpredictable.

Here are some other examples for using the find command:

sudo find /home -user mike

Find all files owned by the user mike in the /home directory

sudo find /etc -name ‘*.cnf’

Find all files in the directory /etc ending with “.cnf”

sudo find /var/spool -mtime +60

Find all files in the directory /var/spool that was modified more than 60 days ago.

These are just a few basic examples on how to use the find command. For a complete list of all of the options of the find command, look at the man pages.
