ZL2PD HF Digital Antenna Analyser
This webpage contains software and project related information for anyone interested in building this instrument.

This HF digital antenna analyser uses a Philips 87C552 microprocessor, an 8051 compatible device. The analyser is the subject of an article currently planned for publication in New Zealand's amateur radio magazine "Break-In" in late 2005.

Break-In is published by NZART, New Zealand's amateur radio organisation. Details about the magazine can be found at www.nzart.org.nz

('Break-In' is a term used in ham radio to describe the method by which an operator sending a message can hear the other party's signal during brief transmission pauses)
