The Battle Creek Special Antenna - This antenna is often mentioned as secret weapon for LF bands (160, 80 & 40 m) operating at many DXpeditions. It is not commercially available but may be loaned to the expedition staff. It was brought to Ham Radio scene by George Guerin, K8GG, Charlie Dewey, W0CD and George Taft, W8UVZ

Antenna Impedance measurement - When experimenting on an antenna it's often important to determine its feedpoint impedance at various frequencies across the operating band. It's easy enough to measure SWR, but sometimes we need to know more detail than this

Collins Radio Association - This site was established to encourage hams, especially the newcomer, to share the enjoyment that comes from owning and operating Collins

PJ2T Caribbean Contesting Consortium - A contest club dedicated to fun, international friendship, and advancement of the contesting art through superior operating technique and maximum application of technology.

Tennessee Contest Group - The Tennessee Contest Group (a.k.a. TCG) is a group of amateur radio operators (hams) who enjoy operating in competitive radio sporting events or "contests."

Greek Lighthouse Award - Greek Lighthouse Award has been instituted by the Northern Greece Contest Team and will be issued to any Ham Radio operator or SWL for QSOs with (or reports from) amateur radio stations operating from Greek's lighthouses.

KH6 - Hawaii Sea Q Maui - Hawaii, maui, Operating only as a ham radio station rental. Located in a private home, accommodating only ham operators. Two towers, two tribanders, one 40 2 el, one WARC. A FT1000MP, TS-940S, FT100, HF only no 6 mtrs No linear operations.

The Texas DX Society - The Texas DX Society is an organization of radio amateurs in Houston, Texas who have a primary interest in DX chasing and contest operating on HF, VHF, and UHF.

Sound samples of digital transmissions - Sound samples of the transmission modes recorded at 11025 samples per second, mono and the message in all of the samples is the same: "the quick brown fox jumps over the lazy dog 1234567890".

Digital modes sounds - Ever wonder what all those funny sounds are that you come across from time to time on the ham bands

Antenna Model - Commercial software for the analysis of wire antennas. runs under most Microsoft 32-bit Windows operating systems—Windows 98/ME/NT4/2000/XP Analyze most wire antennas in free space, over perfect ground, or over real-world grounds with the conductivity and dielectric constant you specify. You describe the antenna to the program in easy-to-use spreadsheet-style input window

glfer - glfer is a program for reception and transmission of QRSS/DFCW signals. It is composed of two main parts: the spectrogram window, where you can see the spectrum of the received signal vs. time the transmission functions, to emit cw characters at a slow but precisely controlled speed, using the QRSS (slow CW) or DFCW (Dual Frequency CW) modes

DXSpider - DX Cluster - DXSpider is a clone of PacketCluster software that runs under several operating systems including Linux and Windows compatible with the AK1A program

CLX Packet Cluster - CLX is a clone of AK1A PacketCluster that runs under the Linux operating system. Freeware packet cluster server software

Aether - Aether is an ham radio logging for the Mac. Aether gives hams logging software that is as powerful, easy to use, and good looking as the operating system it runs on. Designed from the ground-up using Apple’s Cocoa, Aether supports the latest Mac OS X technologies, and provides the experience that Mac users expect.

PSK08 - G4JNT - PSK08 Software for the 56002EVM. PSK08 is a data communications mode identical in operation to PSK31, but operating at one quarter the speed, ie. approximately 8 symbols per second.

MacTNC - MacTNC is simple, configurable terminal software used by amateur (ham) radio operators to control a TNC (terminal node controller). MacTNC performs most of the same functions of other terminal software, but includes buttons for standard commands, and allows the user to configure additional buttons for special purposes. MacTNC works only user Mac OS X because it relies on Unix components of the current operating system.
