The annual S7 (Executive) and S9 (VIP) level Patreon support team members who subscribe annually are privy to some perks, some of which include downloadable PDF documents that cover such topics as common amateur radio terminology explained, a basic understanding of everything from how SSB works to understanding propagation, Q signals, an explanation of the knobs and buttons on the typical HF transceiver, how to get started with Summits-On-The-Air (aka SOTA), plus menu optimizations for such transceivers as the FT-891, FT991A, FTdx10, and FTdx5000MP.
I've been compiling another perk for the annual S9 (VIP) Patreon support team members who subscribe annually. This downloadable PDF will cover FT8 operation with the Yaesu FTdx10, including every menu setting in the FTdx10 related to PSK/DATA, and specifically FT8, plus the settings for the WSJT-X software and a brief tutorial to help a newcomer to FT8 get started making contacts.
If you are an FT8 enthusiast, you know that your computer's clock and the station you are trying to communicate with must be accurate to within +/- 1 second of one another. There are several ways to ensure this. One of the S9 (VIP) Patreon team members, Curt, KB9JQU, recommended JTSync (dk5ew.com/2019/09/09/jtsync/). JTSync can synchronize your computer's clock without an Internet connection, using the signals your radio is receiving via WSJT-X. I downloaded the free JTSync software. In this video, I show how to interpret what it is showing you, how to use it to set your system clock to exact accuracy, even with no Internet connection, and how to verify the accuracy against www.Time.is.
Note that both you and the other station can be off by a minute or two, or even an hour, as long as you are within one second +/- of one another. It’s because FT8 transmits for 15 seconds and receives for 15 seconds. You must be receiving while the other station is transmitting, and vice versa, within +/- one second of one another. FT8 is able to decode signals well below the noise floor because it knows what type of information it is looking for at any point during a receive cycle. You could actually work a station that is more than 1 second off or more, as long as you can synchronize your computer clock with theirs. JTSync can do that for you. Then, after you complete the contact, JTSync can help you return to UTC.
