Antenna Shortwave Links →
An Inverted L Antenna for Small Gardens
The antenna works very well particularly on 40m ZL, VK, 3B9 and Antarctica worked, on 20m you will need ATU as like the W3DZZ the impedance is high on this band
Attic T2FD SWL antenna
I am also an avid listener of other things on the long, medium and shortwave bands
Antennas for Shortwave
Transmitting antennas are much more critical than receiving antennas, although a receiving antenna can transmit if it is resonant
Antenna T2FD
Vi presento l'antenna T2FD per l’ascolto della banda HF
Coax loop antennas for 160 - 10 meters HF bands
Lacking room for a beverage receiving antenna, we constructed several loop receiving antenna to see if we could find a suitable low /lower noise receiving 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
