Antenna Launching for Serious Practitioners - Over the years, I've been developing a negative relationship with trees. I'm all in favor of trees when they mind their own business in forests. It's when they purport to serve as antenna support structures that things fall apart. Russ AA7QU

A multi-band super mini loop antenna - To build this antenna you need a lot that is at least 100 feet across. Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands

Stacked Halos antennas - Stacked halo antennas for omnidirectional coverage by W9KXG

Slinky Antennas - The first recorded use of the slinky as an antenna was by American soldiers during the Vietnam conflict. The slinkies were thrown over trees and used in emergencies when the normal antennas weree out of action

Clover - Clover technical specifications, digital communications mode that conveys 8-bit digital data over narrow-band high-frequency radio.

Clover 2000 - CLOVER-2000 is a faster version of CLOVER (about four times faster) that uses eight tone pulses, each of which is 250 Hz wide, spaced at 250-Hz centers, contained within a 2 kHz bandwidth between 500 and 2,500 Hz

Domino - Domino is the name given by the developers to a family of IFK coded coherent phase single tone MFSK keyed modes, using sequential tone-pairs in two alternate fields arranged as orthogonal but interleaved tone sets.

G-tor - G-TOR is a trademark of Kantronics, Inc. G-TOR (Golay-Teleprinting Over Radio) can be viewed, in part, as a variant of the Automatic Link Establishment (ALE) protocol, outlined in MIL-STD-188-141A.

Mt-63 technical description - The MT-63 modem, constructed around a high speed DSP processor, either in a dedicated external DSP unit like the Motorola EVM, or in PC software using the PC sound card, transmits 64 tones spaced 15.625 Hz apart, in the 1 kHz bandwidth.

Pactor - PACTOR can be viewed as a combination of two earlier digital modes, packet radio and AMateur Teleprinting Over Radio (AMTOR). PACTOR provides improved throughput because its transmission speed adapts to the quality of the link and it uses Huffman compressed characters.

WinDRM - HF Digital Radio Mondiale - WinDRM is the hottest digital mode on HF today! Nothing else exists where you can transfer data at almost 1KB/s without using proprietary hardware. HF Digital Radio Mondiale allow fast data, pictures, and voice over a 2.5Khz bandwidth
