Technical Reference/Sound Card Radio Interfacing
Interface board was for connecting Yaesu FT-817ND transceiver to Android phone or tablet. The board was developed for experimenting with RTTY, SSTV and other digital modes using DroidRTTY, DroidSSTV and other software on an Android phone.
Efficient Low Band Counterpoise for Restricted Circumstances Loss Avoidance Opportunities and Techniques for the Low Bands
The short and linear FCP was designed to reduce ground losses from inadequate radial systems beneath inverted L and other vertical antennas.
In a repost by YT9TP (Serbia) it would appear that the International Telecommunication Union has officially confirmed use of the Z6 prefix is illegal

Learn to recognize Morse code at 25 WPM and not memorize DITs and DAHs at 5 WPM.
This app will train you to hear and send Morse code at 25 WPM using an approach very similar to the Koch method.
A very efficient 80 meter Counterpoise antenna designed to reduce ground losses from inadequate radial systems beneath inverted L antennas, a project by DM2GM and DM4IM based on the original K2AV antenna concept.
