The skyline in Monticello looks a lot different now. A 260 foot tower
that will be soon be home to one of the largest short wave radio
stations in the world is nearing completion. News Source 8’s Ashley
Blackford has the story.
Allan notes that transmitter tests may be taking place within a month.

Thanks to a hat tip from the Southgate ARC, I discovered that the excellent MagPi magazine has featured a number of ham radio projects in this month.
I’ve outlined below a list of the projects with page numbers–note
that many are simply summaries that link to full project notes in
previous editions:
- Page 52: Pictures from space via ham radio
- Page 71: ADS-B flight tracker (we also have a short tutorial here)
- Page 72: WSPR transmitter
- Page 73: Remote SDR scanner
- Page 74: Digital voice hotspot
- Page 75: Satellite tracking
- Page 75: APRS IGate
Issue 80 of MagPi is free ( click here to download as a PDF). You can also pay for a print subscription via post as well.
I highly recommend downloading each issue of MagPi–it’s a brilliant, informative magazine and is chock-full of projects and ideas for Pi fans of any age.
One of my Raspberry Pi 3Bs in service.
I’m a big fan of the Raspberry Pi and use it for a number of
applications. This issue has encouraged me to give WSPR a go and perhaps
even build a DV hotspot in the near future.
Raspberry Pi kits are quite affordable–Amazon has a massive selection
from bare-bones units to full packages which include everything you
need to get started. I’m a fan of both Canakits and Vilros.
I also purchase Pi systems, accessories, and hats from AdaFruit.
Post Readers: Are you a fan of the Raspberry Pi or other mini computers? Please comment and share your projects/ideas!

Lately I’ve gotten a lot of questions from readers about magnetic loop antennas, certainly a popular topic on the SWLing Post. Good discussions underway.
So, when I discovered an extra copy of Joe Carr’s excellent Loop Antenna Handbook
on my bookshelf this morning, it occurred to me to share it with you,
readers. I think I won this copy at a Winter SWL Fest a couple years
ago; it’s chock-full of Joe’s handy tips and solutions to antenna
questions and installation conundrums. It’s still in great shape, and
I’m sure will find a good home with a lucky SWLing Post reader.
Interested? Here’s how you can participate…
The Loop Antenna Handbook is chock-full of antenna theory and practical construction projects.
If you’d like to participate in this giveaway, here’s how: Simply comment on this post, telling us about your favorite radio! Give us the make/model, and just share a few comments about why you love it above all others.
This can be any radio: a shortwave portable, an SDR, a
vintage radio, a ham radio transceiver, a handheld, a scanner, an
aviation radio, whatever…or, yes, more than one, if you simply can’t
choose.
I’ll select a winner at random on Sunday, April 7, 2019.
This contest is open to anyone, anywhere! I’ll post the prize to the
winner directly wherever you are. (Note: Well, if you’re an astronaut on
the ISS, I’ll have to send it to your drop box!)
I’ll also plan to compile and publish the full list of radio favorites in a future post…stay tuned for that.

Two weeks ago I was walking past the steps leading to the
basement, and I noticed that ol’ familiar electrical burning smell. Not
overpowering, without any visible smoke, but enough to set off the alarm
bells in this Ham’s cranium.
I went downstairs to find the smell emanating from our clothes dryer.
The top was very hot and the smell became even stronger after I shut it
off and opened the dryer door. Fearing a lint trap fire, I gave the lint
duct a touch with the back of my hand to see if that was warm. Compared
to the dryer itself, it was stone cold. I went outside to the vent
opening on the house and gave a good sniff. Nothing from that end
either.
Convinced and relieved that the house was not in danger, I unplugged
both the washer and the dryer and let them sit. The dryer cooled off. I
wasn’t sure what the exact cause was, but I suspect that the control
circuit board had gone again, as it did a few years back. The odor was
identical to that of either burnt components or traces on a circuit
board.
The matching washer had been giving us its own problems for over a year
now. I decided that it was time to purchase a new pair. My wife didn’t
object to my statement that I didn’t want a fire hazard in our house.
We went to Lowes, one of the big box hardware stores where Marianne
picked out a pair of machines manufactured by Samsung. I was a little
wary. Our cellphones and TV are from Samsung, but our washer and dryers
have always been Whirlpool, Maytag or even GE going back to my parent’s
house.
They were delivered a week ago; and as Marianne seems happy with them, I
didn’t give much more thought to them - until yesterday. I was
downstairs listening to not much on 20 Meters, when Marianne came down
to put in a load of laundry. I was about to answer a lone CQ from UA3EDQ
when I thought to myself, “Here we go!”
Our last pair of washer and dryer were notorious RF generators. If I was
on the radio and Marianne put in a load of wash, I could literally hear
the agitator motor in my earbuds. I could heard the motor rev up and
die down during the spin cycle. The dryer wasn’t as bad, but was still a
nuisance.
To my delight and surprise the Samsung pair are the antithesis! I was
able to work Igor without having to listen through RF hash. Both the
washer and dryer are RF silent on 20 Meters. I checked the other bands
as well, and they all seem to be free from washer and dryer hash.
So kudos to Samsung! Whatever and however these machines were engineered, they seem to be Amateur Radio friendly!

 “Andrew
Knafel, KN8FEL saw my videos and through our correspondence I helped
him learn how to operate satellites. He and his family live in Ohio but
regularly vacation at Myrtle Beach, South Carolina. He has a long time
friend who lives near Raleigh, which is on the way to Myrtle Beach, who
he usually stops to see.
Since he was in town we met up for an evening to play radio. We
worked four passes on four different satellites. The highlight was
making contact through a satellite while standing mere feet away from
each other. We actually did this twice on two different satellites.  Sponsored by Nordic PC, M2 Antenna Systems, Arrow Antenna, and Dog Park Software”
