Working the World, Using JT65 on HF

Presented by Bill Thomas, WB9KPT

Digital communications modes are becoming more popular for ham radio operators. With HOA CC&R restrictions, many operators are finding that they must use stealth antenna and low power on the HF bands. Using JT65 and related modes, it’s possible to work the world on modest antennas with barefoot rigs.

The JT65 digital protocol was originally developed in 2003 by Joe Taylor, PhD., K1JT,
an astrophysist and Nobel Prize in Physics laureate. He wrote the software package WSJT (Weak Signal Joe Taylor) for his interest in weak signal low-power moon bounce and meteor scatter amateur communications. JT65 has now evolved into a popular mode for working low-power HF.

Bill Thomas' presentation will cover the basic topics that will help you get started using JT65:
how to set up your station, load the necessary software, and make your first contacts.

Specifics will include: what is JT65, computer to rig interfaces, JT65 software, time sync software, proper message sequence for a contact, monitoring your transmissions, a recorded demo of a few contacts and some operating tricks.

A handout will be available that lists websites and download locations for the necessary software.

More information, and Bill's amateur radio bio, is available in the May issue
of the DRC Roundtable Newsletter.

This will be a most interesting and useful presentation...
please mark your calendars now to attend!

We will be meeting at the Jefferson County Administration & Courts Bldg.
