A Lowband Antenna that is Almost Free  ^pop - The Shunt-fed Tower, an effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M.

300 ohm twinlead 40 meter dipole - The N2CKH travel special 300 Ohm ladder line convertable antenna

HF Home made Balun  ^pop - A balun is a device that is used at the feedpoint of a balanced antenna when an unbalanced feedline is desired to feed the antenna. Balun is a contraction for BALanced to UNbalanced.

K6RF Streaming Video - Live video and audio feed from K6RF ex K6DXC radio shack. Audio is from either the FT-920, FT-817 receivers or a microphone. Video is from a Logitech Pro-4000 Webcam

WA4DSY 56KB RF Modem - This is a prototype of the WA4DSY 56KB RF modem. It is intended for use on amateur packet radio networks. The modem generates RF in the 28 to 30 mhz range and requires and linear transverter to convert the signal to a UHF or microwave ham band

VectorFox - VectorFox is a software born to incorporate a PC into the fox hunting environment. VectorFox is able to take inputs from up to 5 sources, such as a 2m beam, a 2m signal meter, a TDOA, etc, and display the results on the screen. VectorFox also accepts Agrelo inputs. From these results the operator can choose which indication is best and have a line drawn on the map in the direction of the signal.

Yaesu FT-857 serial cable - Here is a serial control (CAT) cable that plugs into the FT-857's microphone jack, freeing the CAT/Linear jack for other purposes.

SWR Calculator - Computes the Standing Wave Ratio, given the power readings on a line.

XLZIZL by AC6LA - XLZIZL is an Excel application that analyzes the components of an antenna feed system, including transmission lines, stubs, baluns, and tuners. Calculations include impedance transforms, SWR and reflection coefficient, power loss, voltage and current standing waves, stress on tuner components, network attenuation (S21), and return loss Analysis results are available in worksheet format and in five different chart formats, including Smith charts.
