Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
I look forward to watching this episode later today. Here’s the description via TX Factor:
For your winter entertainment – enjoy part two of our informative series on HF and VHF propagation. Steve Nichols G0KYA concludes with his explanation on how space weather affects our ability to communicate on the HF bands.
Bob parts with some cash at Hamfest and Mike chats to Phil Willis M0PHI and Cathy Clark G1GQJ, two movers and shakers in the world of amateur radio.
Our free-to-enter-draw is back with a chance to win a copy of Radio Propagation Explained by Steve Nichols.

The January 29 edition of Wavescan (which will begin to air on January 29 and will be repeated several times over the following week) will be a special program about Radio Australia, which will be ending its shortwave broadcasts on January 31.
Caroline North is back this weekend live from the MV Ross Revenge on the River Blackwater Estuary near Bradwell, Essex.
Relayed on 1368 kHz with a transmitter power of 20kw from the Isle of Man.
According to Manx Radio’s website as well as being heard in the Isle of Man, the AM service is also audible in Southern Scotland, in the North West, in North Wales and in the West of Ireland and Northern Ireland.
Stampfl was founded by Heinz Stampfl (HB9KOC)–I’ve been following his work the past few years, especially fascinated with his SDR designs which are (sadly) only experimental and have never been put into production.
I’ve written Heinz more than once encouraging him to put these on the market. Of course, it’s an easy request coming from a consumer who doesn’t have to front the production costs and inherent overhead!
Heinz, if you’re reading this, why not do a Kickstarter campaign for one of your fine SDR designs?!
It’s likely the only time you really notice one of your neighborhood broadcast and cell towers is at night when they’re lit up with conspicuous bright red lights.
Those lights help pilots see the huge metal structures that can reach 1,000 feet into the air — but they can spell disaster for birds.
In 1976 in Gun Lake, Mich., one tower killed over 2,300 birds in one night, says Caleb Putnam, who works for the Michigan Department of Natural Resources. He says for reasons scientists still can’t quite figure out, birds kept flying headlong into towers.
“If that many are dying at one night at one tower and yet there are thousands of towers across the country and as you go across the world, the numbers are staggering,” he says.
Putnam says in North America alone it’s estimated that 7 million birds smash into towers every year. But until recently scientists didn’t know why it was happening.
[…]”We were able reduce the numbers of bird fatalities on communications towers by simply extinguishing those non-flashing lights,” she says. “Those fatalities were reduced by as much as 70 percent.”[…]
