Our hobby in 30 years?

Although I cannot speak for other countries, here in the UK ours is a hobby mainly of older people and mainly men.  When I was fitter, I gave several talks to local radio clubs in East Anglia and without exception, it was mainly OAPs who came along. OK, there were a few youngsters and women, but the vast majority were older men.

Amateurs and SWLs are a dying breed unless we can attract young people into the hobby. I am 67 and will be dead within 30 years, probably a lot sooner. An aging population will not buy so many rigs, will not support magazines etc. Numbers will fall, activity will fall, interest will drain away.

In 20-30 years we will be very much in uncharted territory. What will our hobby be like in years to come?

50 Years Ago, These Were the Ads in 73

73march66They say the days are long, but the decades are short. It’s hard to appreciate how far we’ve come in fifty years — both in terms of technology and prices!

Here are a few of the ads from the March, 1966 issue of 73 Magazine. Enjoy the walk down memory lane!

I don’t believe that they’re doing enough to attract new members and retain existing members, and a few recent incidents have only solidified my opinion.

The big ‘secret’ to successful DXing

jim-w6lgJim Heath, W6LG, has launched a new video series about the art of DXing. He should know about the subject — he’s been working DX on 20-meters with great success for over 50 years.

“It doesn’t take a huge station to work DX, and it doesn’t take a lot of money,” Heath says. “You can have a lot of fun with a very modest station.”

He says that one key to success is not getting caught up following the crowd. “The skill is not getting onto a DX net and putting your call sign in and waiting for your turn to work a guy in Japan. That’s not working DX — that’s being spoon-fed DX,” he says. “If you’re new to DXing, go for the easy countries: the guys who are calling CQ.”

Most people who have real success working DX do a lot more listening than talking. “A DXer listens, listens, and listens some more and learns about propagation and knows when the band is going to open to certain parts of the world,” he says.

“A good example of a guy who has a tremendous signal out of Scandinavia day after day is SM5BUS,” Heath says. “If you’ve tuned 20-meters, you’ve more than likely heard him. He knows propagation really well. He’s learned over the years when the band is open and he listens a lot.”
chimney-two-element-yagi“While you might think because this guy is the only thing you can hear out of Scandinavia, that he has an antenna at 100 feet and 1,500 watts behind it. It’s not true,” Heath says. “He’s got a two-element Yagi attached to his chimney 10 meters above ground, but he knows when propagation is good. He’s there to work the propagation, to work the band opening. He does it over and over again and that’s been true for decades.”

  • FCC records show that growth in amateur licenses continued through 2015, with a 735,405 licensees.

First look: Tytera TYT MD-390 DMR HT

tytera-tyt-md-390The Tytera TYT MD-390, the successor of the popular Tytera TYT MD-380 DMR HT, has arrived. Jason Johnston, KC5HWB, unboxes the upgraded DMR HT in the latest episode of his show, Ham Radio 2.0: LIVE! From The Hamshack.

“I think I’m the first one to have them listed online, but that won’t last long,” says Johnston.

Like the MD380, the TYT MD390 is 400-470MHz, features 1000 channels, and is DMR Tier 1 and 2 compatible. New to the MD390 is an IP67 dust/water ingress protection rating (immersion up to 1m).

tytmd390The radio is currently available in the Grapevine Amateur Radio online store for $179.99. Johnston says MD390 is priced similarly to the MD380 when it first came out. “I expect it will probably drop in three to six months,” he says.

In the video, Johnston does a thorough job reviewing the features of the radio. He compares the MD-380 vs. the MD-390 and talks about how he’s been using the radio around the Dallas-Fort Worth area for the past few days since the first units arrived.

Johnston says the radio feels heavier and much more sturdy than the MD-380 it replaces. He also praises its strong audio. “It sounds just as good as the MD-380, maybe even a little bit better,” he says.

If you’ve followed his show, you’ve noticed that he has really stepped up his game in terms of video production. Great job, Jason!
