Helical is a graphics-intensive bandpass filter design and analysis program based on the helical resonator. Main features: - The program designs bandpass filters with a selection of the order from 2 to 12, odd or even. - Center frequency, bandwidth, and passband ripple are all adjustable. The ripple value may be set to zero for a Butterworth response.

This program is designed to facilitate the design of PI and PI-L networks. Main features: - The design screen accepts inputs for the operating frequency, the load as seen by the final amplifier tube *, the intermediate impedance if the L-network is to be used, the output load value and the Q value for the PI-network.

This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immediately see the R and jX values of the load on the network.
