WNJC DX test starting 04:00 UTC on October 18, 2020

Many thanks to SWLing Post contributor, Bill Hemphill (WD9EQD), who shares the following announcement from Les Rayburn (N1LF):

DX Test This Saturday Night/Sunday Morning– WNJC 1360, Washington Township,
NJ

WNJC 1360 DX TEST– SATURDAY OCTOBER 17 INTO SUNDAY MORNING OCTOBER 18

“04:00 UTC-Midnight Eastern- WNJC will conduct the DX audio test using Morse
Code and sweep tones continuing on our nighttime pattern.

At 0500 UTC- 1 AM Eastern I will be switching to our daytime pattern at 5kw
using 4 towers directional to SSE with the DX audio test concluding at 0600
UTC. From 0600 – 1000 UTC I will be leaving the transmitter in daytime mode
but be playing a mix of 80s – 2010 pop, rock, dance, country and whatever
else I grew up listening to and feel like playing.

Listen for the sweepers between songs of movie & tv show clips along with
our voice-over guy.”

WNJC has tested previously and been heard as far away as the West Coast of
the United States and Canada. Their test signals have also been received in
the UK, Norway, and Spain. Listen for their signal if you get the chance.

Thank you for the tip, Bill!

QTC Article: Clear Channel MW Broadcast Stations in Australia

4 Replies

Many thanks to SWLing Post contributor, Kris Partridge, who notes that the July/August 2020 issue of the Australian amateur radio magazine QTC (an issue we noted in a previous post is free) actually has an article about the mediumwave scene in Australia.

Click here to download a PDF of those pages only from the magazine, or better yet, grab the full issue from our previous post.

Thanks for pointing out this article, Kris. I really enjoyed reading this issue of QTC. Great to see a ham radio publication that covers more than *just* ham radio!

Giuseppe’s cross-loop experiments

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

I’m Giuseppe Morlè from Formia, central Italy, on the Tyrrhenian Sea.

I wanted to share with you and friends of the SWLing Post community this antenna project of mine dedicated to those who do not have enough space on the roof or in the garden to install antennas.

These are two separate loops, with two different diameters, one 60 cm, the other 90 cm, each with two variables for tuning … the system is able to receive from 3 to 30 MHz.

I joined these two loops in an opposing way, better to say crossed that can communicate with each other due to the induction effect that is created between the two small coupling loops that are placed one under the other at the top.

In the videos you will be able to see how the antenna system receives. I can use one loop at a time, to detect the direction of the signal or I can use them together for a more robust signal and in an omnidirectional way.

I really like experimenting with the induction effect and you can see that even when closed at home the two loops do a great job.

From my YouTube channel:

I’m not a technician but I really want to experiment to try to listen as well as possible.

Thanks to you and CIAO to all the listeners of the SWLing Post community.

Giuseppe Morlè iz0gzw.

Very cool, Giuseppe! I must say I’ve never tried dual loop experiments like this where one can experiment with the induction interplay. I imagine this could give you some interesting nulling capabilities if you have an unwanted station interfering with a target low-band signal. Thank you again for sharing!

Can you help Carlos ID this station on 530 kHz?

Many thanks to SWLing Post contributor, Carlos Latuff, who recently shared a video clip of a Spanish language station he received in Porto Alegre, Brazil. Carlos is curious if it could possibly be Rádio Rebelde in Cuba. He said he received this station early in the morning (local) on Sunday, April 26:

If you can help Carlos ID this station, please comment!

KJJR DX Test on Saturday (May 2, 2002)

Many thanks to SWLing Post contributor, Paul Walker, who shares the following announcement:

KJJR 880 Whitefish, MT(Kalispell) will test for 1 hour at 10kw non directional Saturday May 2nd 12:01am to 1am mountain time. It will consist of morse code, sweep tones, along with various telephone sound effects

There will be no paper QSL’s issued for this test. Only emailed confirmation. Send an email to [email protected] with “KJJR 880 DX Test” in the email (You MUST put that in that subject line so I don’t accidentally delete it thinking it’s spam!). The reply will likely be a simple email reply with details of the station and confirming the details of what/when you heard it. You WILL get a reply from me in due course, please give me some time!

This is done on short notice and being kept simple as to not burden anyone involved. Thanks to Les Rayburn for creating the test material and Todd Clark for generously offering up the station. I’ve already seen communication between him and the station, asking them to block out an hour from the logs, so he can tinker around with things at the tower site.

Thanks for the heads-up, Paul! Here’s hoping a few MW DXers can log this test.

Video: “Tribute to a Century of Broadcasting”

Many thanks to SWLing Post contributor, Bill (WD9EQD), who writes:

You probably have already seen this, but from The ARRL Letter, November 21, 2019:

Art Donahue, W1AWX, of Franklin, Massachusetts, has posted his “Tribute to a Century of Broadcasting” video in recognition of the centennial of formal radio broadcasts. The video features a complete scan of the AM broadcast band (530 – 1700 kHz), with station IDs for all 118 AM radio channels.

Following is ARRL Link:

Radio Amateur’s “Tribute to a Century of Broadcasting” Video Debuts on YouTube

Following is YouTube link to the video:

It was a lot of fun to watch the video, hear the on-air id checks, and compare what he heard to the list of stations that I have heard.

Thanks for sharing this, Bill–I missed reading about this in the newsletter. This goes to show you that the AM dial is chock-full of stations here in North America. Those who complain that it’s “dead” simply aren’t listening.
