- linSmith is a Smith charting program mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation. Users can enter either discrete components or transmission lines, then see the results on screen or generate Postscript output. Component values can be changed numerically or using scrollbars. Problems can be solved on-screen, and high-quality Postscript can be output for publication.
Its features include
- Definition of multiple load impedances (at different frequencies)
- Addition of discrete (L, C and transformer) and line components (open and closed stubs)
- Connection in series and parallel
- A 'virtual' component switches from impedance to admittance to help understand parallel components
- Charts that work in real impedances (not normalized ones)
- Generates a 'log' file with textual results at each intermediate step
- Stores load and circuit configuration separately, permitting several solutions without re-defining the other.
- Modular toolkit for very low frequency (VLF) radio signal processing and storage.
- 'Xlog' is an easy to use program for logging your radio contacts. You can open, close and create logs as needed, and add, delete and edit individual log entries. The log is saved into a text file. It supports cabrillo, ADIF, trlog (format also used by tlf), and EDI (ARRL VHF/UHF contest format), and can import twlog and editest files. Logs can appear in either portrait or landscape format. Xlog is able to do DXCC lookups and will display country information, CQ and ITU zone, location in latitude and longitude and distance and heading in kilometers or miles, both for short and long path. It supports locator distance and heading calculation for VHF logging if you enable the 'QTH Locator' field.
- 'xtalfind' checks whether an XTAL is suitable for a ham radio circuit (TX, RX). Given a base XTAL frequency, it shows you all possible uses within ham bands. It features CW TX and direct conversion RX, and supports 455kHz, 10.7MHz, and custom IF value receivers, DRM, and SDRadio applications.
