Many thanks to SWLing Post contributor, Frank, who writes:

Hi, I am Frank SWL F14368, organizer of the SWL Contest 2024. I have written an article [about the use of WebSDRs]. Maybe you like to share on your nice website for SWL ?

My contest is open to listeners who use a Kiwi or a WEB SDR. Not many contest accept this.

Thank you very much.

Best regards

Listening In Brazil ZP-30 Radio Station, “The Voice Of Paraguayan Chaco”, AM 610 kHz.

by Carlos Latuff

The first time I tuned on to ZP30 “The Voice of Paraguayan Chaco”, a Christian radio station from Paraguay, was during tests with Innova KV-12002. It was 7 p.m. Brasilia time, and when I turned on the receiver, I came across a medium-wave broadcast with an announcer speaking in German. This surprised me because the medium-wave stations I usually receive at night in Porto Alegre, Brazil, are from Argentina, Paraguay, and Uruguay, and none typically broadcast in a language other than Spanish.

I listened to the news bulletin, entirely in German, and throughout the transmission, I noticed the word “Paraguay” mentioned a few times. I concluded that it must be a Paraguayan radio station broadcasting in German. A quick Google search for radio stations in Paraguay broadcasting in German led me to ZP-30. I found their website, tuned in to the streaming audio, and confirmed I was listening to the same station on my radio.

Check out the ZP-30 website here: https://www.zp30.com.py

At that moment I recorded a video of the radio station playing German songs. I wanted the news bulletin, but I found it quite difficult, either due to problems with propagation, other kinds of interference, or due to a station that operates on the same frequency and that sometimes overpowers the Paraguayan broadcaster.

It took me almost a week to record the news bulletin with decent audio quality, using a ferrite rod AM antenna and my good ol’ XHDATA D-808 receiver.

This station, in addition to German and Spanish, broadcasts news and Christian preaching in languages ??spoken by indigenous communities from the Chaco region in Paraguay.

In Brazil, there was a migration of AM stations to FM, which left the medium-wave spectrum vacant. I believe that, from now on, it will be possible to listen to stations that I had never heard before. Stay tuned!

Some Christian preaching in German:

Adi spots two rare receivers on eBay. What are they?

FURUNO RH1-1 Radio Receiver

Many thanks to SWLing Post contributor, Adi, who writes:

Hi Thomas, I was just browsing eBay when I decided to see what was “new” in the receivers section.

These popped up:

https://ebay.us/iRSC87 [eBay partner link]

RH1-1? [See photo above] Google doesn’t know much about it.

Pfitzner – Teletron type TE712B

https://ebay.us/RNQEy3 [eBay partner link]

The seller from Poland writes, “The receiver was produced specifically for reconnaissance purposes.” I wonder what was heard through its circuits…? ?

I guess a few readers can tell us more about them.

Regards,

Adi

Thanks for sharing, Adi. I’m not familiar with either of these receivers, but I’m sure some of the experts in our community can shed some light on them!

WWII Radio History: D-Day broadcasting and communications

Many thanks to SWLing Post contributor, Kris Partridge, who writes:

With the imminent approach, Thursday, June 6, 2024, of the 80th anniversary of D-Day, followed by operation Overlord.

Being both a radio amateur and in the broadcast industry , I have done a little research and find the two items, below, relating to D-Day and post-D-Day communications and broadcasters.

One, from the BBC Archives for a UK ‘view-point’

and Two, from RadioWorld for the US angle

But remember it was nearly a year away to VE-Day, so more research to be done on the effort of broadcasters to “bring the story home”

Also, one amateur radio related note: A SES (Special Event Station) with the callsign GB8ODD: https://g5fz.co.uk/up-coming-special-event-stations-by-the-lswc/

Being a WWII history buff, I really appreciate the links. Thanks, Kris!
