Antenne G5RV
It is a multiband antenna which is similar to a center-fed or a Levy antenna of particular dimensions chosen to obtain a low impedance on frequencies close to 3.5 7 and 14 MHz
Coaxial fed multiband windom antenna
This simple multiband antenna works on all HF bands from 3.5 to 30 MHz, including WARC bands other than 10.1 MHz
Build a sturba curain antenna for hf bands
The Sterba Curtain, as designed is non resonant.There are a couple of bands where the swr will drop to 3:1
Inverted V for 17-20-30-40m
A 4-band 17-20-30-40m antenna that rolls up into an small Grundig antenna case

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
RF Inductance Calculator Mean diameter of the air core coil, measured from conductor centre to conductor centre include the wire insulation thickness, if any
