A two dollar helical hf portable antenna  ^pop - Here’s an easily transportable vertical antenna for 20 meters collapsible to 4 feet that costs about $2.00 to make. This was created as a fun project to demonstrate how to enjoy operating HF in the field with a home-made portable antenna without spending a ton of money. Bev AH6NF (YL) made this antenna, tuned and ready to operate in less than one hour

45SD105 Vlada - Personal web site of a freebander, info on 11m digital modes, pictures of antenna projects

NCDXF/IARU Beacon Project - The NCDXF, in cooperation with the IARU, constructed and operates a worldwide network of high-frequency radio beacons on 14.100, 18.110, 21.150, 24.930, and 28.200 megaHertz. These beacons help both amateur and commercial high-frequency radio users assess the current condition of the ionosphere

CW Decoder  ^pop - This program allows CW operators to copy CW code with a computer. The decoded CW is displayed as text or can generate a side tone. There is a spectrum display of the audio with a sliding cursor to select a particular audio for decoding. The program also allows for keying a transmitter from the keyboard with full CW break-in operation.
