50MHz J-Pole Antenna  ^pop - Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

Stream - Stream is a software that implements MFSK16 and MFSK8 modes designed by me and Murray Greenman ZL1BPU. It also offers a series of experimental modes based on FEC, interleaving and several modulation techniques (PSK, QPSK, MSK, &c.).

Smith chart calculator - linSmith is a Smith Charting program, mainly designed for educational use. It allows defining multiple load impedances (different frequencies), and adding components (discrete components and line sections) in series and parallel. It plots the impedances on the screen, shows the values in table format, and is able to generate publication quality Postscript output.

IZ8BLY Stream - Stream is a software that implements MFSK16 and MFSK8 modes designed by me and Murray Greenman ZL1BPU. It also offers a series of experimental modes based on FEC, interleaving and several modulation techniques (PSK, QPSK, MSK).

FT1000MP-SuperControl - FT1000MP-SuperControl is a complete CAT control and "better than nothing" logging program, based on the legendary FT847-SuperControl program. The program has been developed especially for the FT-1000MP transceiver series including Mark-V and Field.

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.
