The Ramblings Of G7SYW
The square halo, or squalo, for 6m originally designed by John (KG4OSA) and published by Jan (PA3EGH) is a square, folded dipole that can be easily constructed from some copper tubing.
The basic design of the antenna is a fairly simple folded dipole.
In simple terms, a serial port interface translates signals from a computer serial port to be used to place a transceiver into transmit or send CW (morse code) characters.

Like almost every other radio ham, I use a computer for log keeping, digital modes and other tasks. For the majority of computing processes in the shack I employ the use of a home built Windows PC. The hardware was originally based around an ECS GF8100vm-m5 motherboard with 4GB RAM and a 500GB hard drive.
This machine started showing a problem with one of the SATA channels. At very infrequent random periods data would get corrupted – not good. Therefore, I replaced the motherboard before I lost any crucial data. A nice new Asus M5A78L-M is now installed as the replacement for the ECS motherboard.
