The wave of software-based digital modes over the past several years has altered the atmosphere of the HF bands. Some suggest the popularity of modes that make it possible to contact stations neither operator can even hear has resulted in fewer CW and SSB signals on bands like 6 meters and 160 meters. Traditional modes require far more interaction and effort on the part of the operator; the newer digital modes not so much. The recent advent of the still-beta quick FT8 mode, developed by Steve Franke, K9AN, and Joe Taylor, K1JT the F and the T in the modes moniker has brought this to a head. Some now wonder if FT8 marks the end of an era and the start of a new, more minimalist age.
Weve been as surprised as anyone about the rapid uptake of FT8 for making QSOs on the HF bands, Taylor told ARRL this week. Rather than viewing FT8 as a total game-changer, he sees a dividing line between such digital modes and more traditional modes.
SSB and CW are general-purpose modes, Taylor asserted. They are good for ragchewing, DXing, contesting, emergency communications, or whatever. FT8 and the other modes in WSJT-X are special-purpose modes. They are designed for making reliable, error-free contacts using very weak signals in particular, signals that may be too weak for the more traditional modes to be usable, or even too weak to hear.
Taylor notes that the information exchanged in most FT8, JT65, and other digital-mode contacts is little more than the bare minimum for whats considered to be a valid contact. In addition to call signs and signal reports, stations may exchange grid squares and acknowledgments.
Radio amateurs recently commented in response to a Top Band Reflector post, in which Steve Ireland, VK6VZ, averred that because of FT8, 160-meter DXing has changed, perhaps forever in recent weeks. Ireland said he downloaded FT8 but just couldnt bring himself to use it on the air. My heart isnt in it, he wrote. My computer will be talking to someone elses computer, and there will be no sense of either a particular persons way of sending CW or the tone of their voice. The human in radio has somehow been lost.
In his blog, Steve McDonald, VE7SL, compiled not only Irelands posts, but some responses to it, although not identified by name or call sign. One commenter suggested that the game-changing aspect of FT8 is that those who typically operate CW or SSB will gravitate to FT8. The amount of activity on the FT8 frequency of any band is phenomenal, the commenter observed. A few complained that no skill is involved in making contacts using computer-based digital modes.
Another suggested that FT8 is already falling victim to its own success, with too many stations crowding around the designated FT8 frequencies. Others were more philosophical, with remarks along the lines of this one: It is allowing people who have smaller stations the opportunity to get on and use their radios and a computer to make contacts they never would have been able to make. This is great for ham radio!
Taylor would agree. As he sees it, FT8 wont replace modes such as CW or SSB. Nevertheless, its clear that at least in the short term many hams enjoy making rapid-fire minimal QSOs with other hams, all over the world, using modest ham equipment, he said. For this purpose, FT8 shines.
In a related lightning talk at the 2017 ARRL-TAPR Digital Communications Conference (DCC) earlier this year, ARRL Contributing Editor Ward Silver, N0AX, challenged his savvy audience to develop a keyboard-to-keyboard mode between FT8 and PSK31 that would support casual and competitive operating, be more interference and noise tolerant, and be usable by those with compromised stations and antennas. He also challenged his listeners to develop a smart spectrum display that would identify signals by mode, so Amateur Radio could move away from the practice of setting aside specific frequencies for digital modes.
Man you ARE a fossil ;-). But the cool thing is, radio is still magic and the oldest modes still work just as well as ever for those who prefer to use them.

“Got a...somewhat-modern HF rig?”
Nope. Total novice.

I can confirm the recent rise in popularity of FT8. Apparently the software defaults to the same frequency as our evening traffic net. Through some negotiations this default was moved a couple kc down, but it seems many are still using the old default. After a couple months we gave up and moved our net.
5 watts and one of these babys
No computers, no extra stuff.... Old school radio.
Have not been to a Hamfest in years, but I think that is one of the best places to look for an “inexpensive” Ham rig.

Or even better, find a local Ham Club that has license classes. They are usually the people who give the exams.
I first sat before an FCC examiner in 1976, on Commerce Street in downtown Dallas. Had an Advanced License from that year to 1985 when I took my Amateur Extra exam. Commercial license came later.
Amateur Radio Clubs vary a lot. Some have a lot of technical oriented members, others don’t. There was a time when most were X-military or worked in commercial radio fields. Not so much now.
Now they give you the question pool and the answers. It makes it a lot easier to prep for the exam.
When I got my first license, there were study guides but the question pool was blind. I was scared to death for the first exam.
I’ve taught both Amateur and Commercial Radio license classes. (not recently)
Over the years I have been fortunate to meet some of the most interesting people because of Amateur Radio.
My favorite rig is still my Collins Twins. (75S-3/32S-3) In the early 1980’s, I built a general coverage frequency synthesizer for it, giving general coverage.
My first HF rig was a Galaxy GT550A transceiver, bought it new when Galaxy was being closed down in 1976. It was a hybrid rig (mixed tube and transistor). It had a great receiver and the only real drawback was the final tubes, it used a pair of 6LB6 TV sweep tubes. The problem was it required matched pairs. I had access to cheap tubes at the time, I worked for a wholesale distributor that had a division who sold Zenith. At first I just matched them. As tubes got harder to find I modified the final wiring to allow balancing the tubes. It was a little tricky to do but worked well.
Those were good days. Still have that rig too.

Welcome to the 21st century.
Still,,,
Breakin’!
Bookmarking your post; many thanks, as I too am hearing impaired.
And it’s the reason why many humans remain non-digital in the HF realm.

If you’re asking about antennas, I’d say Kent Electronics. http://www.wa5vjb.com/
