Visual CW Tuning Indicator
Many transceivers set the CW transmit off-set equal to the set's sidetone frequency. But it was left to the operator how to match incoming signals to the sidetone for one-frequency QSOs -- an awkward and time-consuming procedure

Variometer Loading Coils for LP AM operation
LPAM antennas are more difficult to construct than their LPFM cousins. Firstly, they have to be longer. Secondly, they have to be vertical to work well which becomes an issue if the antenna is longer) Thirdly, they need to have rather long ground radials for the same reason
Voice Keyer vacile da usare e da costruire
Decisi quindi di costruirne uno semplice
Yaesu FT-817 abilitazione alla trasmissione continua
Puo' essere modificata per abilitarla a trasmettere sull'intero spettro delle HF
The Skew-Planar Wheel Antenna

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
