SI473x Receiver Firmware Update and Internal Photos

Many thanks to SWLing Post contributor, Robert Richmond, who writes:

Hi Tom,

Ricardo (PC2CLR) recently published an excellent firmware update for the SI473x kit-based receivers flooding AliExpress, eBay, etc.

I purchased a preassembled SI473x model, and it has a much better user interface following the update IMO. Other changes include being able to tweak or disable soft mute, finer grained attenuation, and a few options being moved to the encoder instead of multiple button presses.

The update including directions and a list of features can be found here:

John’s 1965 RCI Shortwave Club certificate triggers serious shortwave nostalgia!

Hi Tomas,

Seeing [the] article about RCI prompted me to remember the halcyon days of SW Listening.

I still have my RCI Shortwave Club certificate issued in 1965 when I was only 14 years old!

In those days you had to monitor their broadcasts regularly and send listening reports on (if I remember correctly) green airmail reception forms every month.

Hope the attached may give other readers some memories.

Wow! Thank you for sharing this, John. Those were, indeed, the halcyon days of shortwave radio listening!

Post readers: Please comment if you’ve also received a certificate from RCI!

Radio Songs by Silvia Swart

Many thanks to SWLing Post contributor, Bill Hemphill, who writes:


I ran across a reference to Radio Delta International Shortwave, a Hollands station on 6020 kHz.  The reference was to a song that was recorded for them by Silvia Swart en het Radio Delta lied.  Which (according to Google) translates to The Radio Delta Song.  It’s on YouTube and I like the sound of it even thought I don’t know Dutch.

YouTube link to the Radio Delta song:

There’s some nice photos and background to the station equipment on Delta Radio web site;

https://radiodelta.am/

After listening to the song by Silvia Swart, I did a search on her and found that she did other radio songs.

Radio Krachttoer:

Radio Combination Team:

Hopparadiotune:

Radio Waubach:

Hinnehok fm lied:

Supervision Radio:

Next step was to dive in and learn a little more about her.  Thank goodness for Google Translate.  From her website

https://www.silviaswart.nl/

I learned that Silvia has made over 155 tunes for legal / illegal pirate stations, associations.

Her parents run a record shop in Holland and that her father, Record King JB Swart, produced the Original Pirate Hits.  From his web site

https://www.jbswart.nl/

I learned that his store carries Pirate Music as well as the usual Dutch and other stuff a record store would normally carry.  Now I understand her interest in radio.

One last song I found that she recorded with her group, The Greenlights:

Mijn opa is een zendpiraat

Which translate to: My grandfather is a radio pirate

Maybe one of the forum members can give us a quick translation/summary of the songs.

NHK World celebrates 80 years of radio service

(Source: NHK Radio Japan via Rich Cuff)

Radio service for overseas marks 80 years.

A ceremony has been held to mark 80 years since the start of radio service at Japan’s only station broadcasting programs overseas on shortwave bands.

The KDDI Yamata Transmitting Station in Koga City in Ibaraki Prefecture, north of Tokyo, is used by NHK World Radio Japan.

About 50 officials from NHK, KDDI and other entities took part in the ceremony on Wednesday.

The chief of the communications ministry’s Kanto Bureau of Telecommunications, Tsubaki Yasufumi, said remotely at the event that he honors the station’s 80 years of stable operations. He also said he hopes for continued efforts so that programs from Japan can be broadcast overseas.

Terada Kenji of the NHK Engineering Administration Department said shortwave broadcasting served as a lifeline on many occasions such as the 2014 coup in Thailand. He said he wants to express gratitude to all the people involved in shortwave broadcasting.

After the ceremony, the head of the station, Saito Toshimitsu, said it plays an important role in providing information from Japan. He added that he will keep working hard so that the station will be passed down to younger generations.

Passing by the Delano Transmitting Station

Many thanks to SWLing Post contributor, Tracy Wood, who snapped the photo above as he passed by this former IBB facility. Tracy noted:

The antenna field is still intact.
As a kid, the signals would leak into cheap AM radio sets in Oregon.

I could only imagine they would!  Thanks for sharing this, Tracy. Amazing to see that the antenna field is still standing.

Behold the epic Sony CRF-320!

Many thanks to SWLing Post contributor, Phil Ewing, who highlights this tweet from @Ea4Hng:

“Testing the good old Sony CRF-320 after many years not in use. It works flawlessly in all bands”

EA4HGN’s photo, above, reminds me that the Sony CRF-320 sports one of the best designs I’ve ever seen in a portable radio. A proper Apollo era aesthetic!
