Dire Wolf is a sound card based modem for packet radio. It can be downloaded for Windows and Linux here: https://github.com/wb2osz/direwolf Although there is a reference to MacOS, there are no further build instructions for Mac. Google reveals some info: one site references an outdated version, the other one proposes to install the brew build/port environment to provide the cmake tool. Installing an environment like brew for just one tool, which actually is a build tool by itself, is .. well .. odd. So I decided to build Dire Wolf on Mac without any hacks or special tools. After using the result for some time,Read More →

I finally decided to go with Mac for Amateur Radio stuff. Time Machine and Spotlight make life so much more comfortable. Not to mention good sleep/wake performance, terminal with bash command line etc. Of course, there will always be some tools that are Windows only, so I use Parallels for this. Download your Windows tool on Mac with Safari, organise stuff in iCloud and then just double click the installer program from Mac.

Interestingly, the circuits in all rigs except the IC-705 are identical. Actually the clock circuit in the IC-705 is just a little different. “I have a clock in my shack, don’t need one in my rig..” Well true, I also don’t need a logbook program, I like to write. I don’t need the dx cluster, I like to listen toRead More →

So your site has a login page? Ever wondered how many “people” are knocking on your door? When I looked at the login attempts on my SSH front door, just shortly after new server deployment, I decided to change doors (ports..). SSH login attempts are in the logs and are fun to look at. But how about failed WordPress logins? First of all, they are not in the logs. But this can be fixed easily like this: —> create directory mu-plugins mkdir /var/www/<your site root>/wp-content/mu-plugins —> create file wp-fail2ban.php in this directory <?php function admin_login_failed_403() {     status_header( 403 ); } add_action( ‘wp_login_failed’, ‘admin_login_failed_403’Read More →
