Opto Coupler for Keying
ith an opto coupler component 4N25 and the circuit in FIG.1, we have excellent isolation between transceiver and computer, because there is not any undesirable "ground loop" between TX & PC
PIC-Keyer
This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
Power Supply for small tube amplifiers
For tube amplifiers, independent if HF or AF, it is more difficult to find 50 Hz transformers with appropriate output voltages for a reasonable price
Programmatore seriale per PIC
Collegato ad un computer permette tramite apposito software di trasferire un programma
