Amateur radio has a new toy to play with, a new digital mode called FT8. The name
comes from the first two letters of the last names of its developers, Franke (K9AN) and Taylor (K1JT), plus the number 8 because it uses 8 frequency shift keying. The new mode has only been generally available since late June or July 2017 when it released as a beta. And it almost immediately took over amateur radio down on the HF bands. I’ve seen estimates that claim that more than half of all contacts on HF are now taking place using FT8.
FT8 is a “weak signal” mode, meaning that you can often successfully decode signals that are down around -20 dB. This is not as good as some of the other digital modes out there such as JT65 which can go as low as -28 dB. But it is much, much faster to make a contact with FT8 than with JT65. Like any communications mode, it has advantages and drawbacks. And like most digital communications modes, it requires a computer interfaced to your transceiver.
I’m always up for something new, and with temperatures hovering down around 0(F) fiddling around with FT8 has seemed like a good way to spend my free time over the last few days. I already had the WSJT software installed on my Win10 computer but hadn’t really had much incentive to do much with it until now.
I won’t go into the details of getting the software installed, configured, hooking things up to your transceiver, etc. There are dozens of tutorials out there. How you set it all up is going to depend on your computer, what transceiver you’re using, sound card, etc. In my case I’m using a Kenwood TS-990 with a RigBlaster Advantage, the same equipment I use for my other digital modes.
Initial setup wasn’t too difficult. The FT8 Operating Guide by Gary Hinson was a big help in getting everything working properly and is highly recommended.
Much to my surprise, I actually got everything working without a great deal of difficulty and after getting set up and calibrated I took a stab at calling CQ on 15 meters and actually made a contact. WA7MPG in Canada BC.
So, what’s the controversy I mentioned in the title of this? Nothing less than (drum roll please) the end of amateur radio! (Imagine spooky voice saying that)
Yes, according to some out there, FT8 heralds the end of amateur radio. Well, true, they said the same thing about SSB, packet radio, repeaters, PSK, digital voice, SSTV, dropping the morse code requirement and, well, pretty much every innovation to come along in the last 100 years or so. But this time it’s really the end! Really!
The complaints are due to the fact that FT8 is almost entirely automated. Contacts via FT8 consist of brief, 15 second long exchanges of call sign, grid location, signal strength, and then a 73 to end, all done by the software. A click or two of the mouse is all it takes to start the whole process, and then you sit back and watch the computer do the work.
And this is what they’re complaining about. It takes the “human element” out of the whole thing, they claim. It is just making contacts for the sake of racking up another contact in the log. It isn’t “real” amateur radio. It isn’t real communications. It’s just two computers talking to one another.
The arguments are just silly, of course. Yes, it’s real communications. Information is being exchanged. And as for the other arguments, well, the same things could be said about any digital mode of communications; RTTY, PSK, etc. If you monitor the people who use those modes you’ll quickly find that most “conversations” take the form of pre-written and stored messages or macros that are sent automatically. Heck, if you monitor the CW portions of the bands you’ll find a lot of people are doing the same thing even with CW using decoding software and keyers.
Look, amateur radio includes a huge variety of methods of communications, both analog and digital. Everyone has their own favorite thing to do. But there are a lot of amateur radio operators out there who can’t afford to operate a contest quality station with acres of antennas and ten thousand dollar transceivers and amplifiers, but who would still love to log contacts with other amateur radio operators in far off places. FT8 allows people with modest equipment and antennas to use a weak signal mode to make contacts that they normally would probably never be able to make. It doesn’t encroach on the territory of the SSB or CW portions of the bands.
So why all the complaints? I’m not really sure. FT8 has become wildly popular for a lot of very good reasons, and it isn’t going to go away any time soon. Even better, it’s getting a lot of amateur radio operators who weren’t all that active before to start exploring the hobby once more.
Am I going to use FT8 a lot? Heck, I don’t know. I’m one of those very odd amateur radio operators who doesn’t actually like to talk to people. I’m more into it because of the technology. But I still like to get on the air once in a while, if for no other reason than to test equipment and antennas. FT8 could at least make my contact log look a lot less sparse, so maybe. We’ll see.
