Choke Balun Designs - In this designs G8ODE explains different methods to builds a choke balun

A Portable Multi-Band Magnetic Loop Antenna  ^pop - Described here is a simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres, but by changing the overall length of the wire coverage of other bands is feasible

Petlowany Three-Band Burner Antenna - a simple, low-cost, trapless short vertical antenna which amazingly works on three HF bands (20, 15 and 10 meters)

30m QRSS Junkbox Beacon - This simple 30m QRSS beacon is built entirely out of junkbox parts, the only component purchased specifically for this project was the 10,140kHz crystal.

Two Meter FM Simplex - Two meter fm simplex ham radio list.

DOMINO - new MFSK mode - A new MFSK mode with IFK by ZL1BPU and ZL2AFP.It is a simple Amateur Radio mode for keyboard QSOs. domino provides digital chat-mode operation on the HF bands, using the well respected sound card technique. Domino will handle TX/RX offsets and mistuning of 200Hz with ease, and will provide perfect copy of drifting signals up to 200Hz/minute!

IMAGINE QSL's Print Service - We design and print QSLs (simple,double,triple...), calendars, awards, directories... High quality at lower price

Azimuth - The AZIMUTH program plots a world map in either azimuth (beam heading) or Mercator projections. If you specify your home location in latitude and longitude, the azimuth projection is centred on your location. The Azimuth map program can display Maidenhead grids - this is useful for 6m, 2m, and UHF DX communication display. Various features of the map are: Azimuth or Mercator projections , Maidenhead grid display, Simple map zooming, Print maps with adequate resolution up to one meter sized map

Morse Mail - Simple text format that encodes mark and space times to make it possible to send Morse coded messages via email

My Morse Trainer - Easy and simple Morse code training program for windows

MorseGen - MorseGen is a simple program the purpose of which is to generate Morse Code at whatever speed you feel comfortable reading, for practice purposes. It wasn't designed to be a tutor for those who know no Morse at all, although you might find it useful for that purpose. It doesn't have a feature for sending small character groups over and over, although this can easily be achieved by creating text files containing the character groups you want to practice.

Smorse - Palm OS morse code software, simple morse code sender, sends code on the built-in speaker at 1-80 WPM. Higher speeds are sloppy because of the 10 msec resolution of the internal timer.

HAMIC - The Ham Intelligent Calculator - HAMIC, is a program designed to simplify a number of calculations commonly used by HAMs. It is designed for the HAM radio hobbyist, but may be useful to others as well. HAMIC has a simple to use, but powerful graphical interface that allows solving simple circuits such as resistors in series or parallel, or more complex circuits such as L networks or T networks. As well, other calculations such as SWR and reactance conversions are supported. Windows shareware.

Simple CMOS elbug - It is a simple electronic keyer that proved to be reliable, precise timing and no own phantasy by OK1DX
