Involved in development of features in AudioRTA PC based audio spectrum analysis, once available at Now only available to users who need it. See brief discussion

Now considering bringing back PkGOLD and KaGOLD for the many amateurs who have told me that these programs are still the best available for AEA-PK232, DSP-232, KAM, KAM Plus, KPC-3, KPC-4, KPC-9612 supporting call recognition, automatic exchange of information, binary file transfers, conferencing, etc

rev July, 2017

Rev April, 2018 - Using ICOM IC-7300, remote operation from Orange County CA to IC-7300 owned and operated by Rich, WZ2D who allows me to access his radio from California. When on Rich's radio, am running 100w PEP to 10-40 meter Beam at 70' with excellent coverage.

My Software Story

InterFlex Systems Design Corp for years, developed and sold KaGOLD and PkGOLD with the help of local ham/programmer.

Also wrote major sections of microcode for RC-210 repeater controller that included all the code for Meter setup (using the analog to digital input, and my code to create meter readings) all the code for Voice Recording, Plaback, Erasure, etc. Numerous revisions to make the code smaller so it would actually fit into the microprocessor system in use. See page 45 of the manual and the chapters on Meter Faces and DVR both patterned by me to emulate RC-850 Controllers on my two repeater systems.
