Wouldn’t it be awesome to have Morse Code playing instead of plain ringtone on your phone? You would know who calls without need to reach phone. Of course it would require you to have skill of recognizing Morse Code, but that is minor issue, right? If you do not know it yet, it can be learned. It’s great skill to have, anyways.
Well, there is simple tool that may help: Morse Code Generator. It creates audio file with sound of Morse Code using your custom text. Generated sound is nice sinusoidal tone, pleasant for ears.

Building dipole antennas is always some kind of improvisation. Center insulator is quite simple and may be made in short time with jigsaw and drill.

You may have need to have accurate time on your Windows PC. Windows already does have support for network time server synchronization and with recent versions ti should be set and turned on by default meaning if PC has access to Internet it will synchronize its internal clock with some of the world atomic clocks.
However, it might be good enough as synchronization is set to rather infrequent time periods, one day or even whole week. For some purposes it is needed to have clock synchronized more frequently. I need it for working Amateur Radio digital modes.
There are number of third party applications that can be installed on Windows PC as SysTray applications or services and allow more precise time synchronization. […]
