Four weeks of Comb Stereo tests via WRMI!

Many thanks to SWLing Post contributor, TomL, who has put together a four week series of Comb Stereo tests that will be aired on WRMI. Here’s the full announcement:

Starting this Saturday June 5 at 01:45-02:00 UTC (Friday 9:45pm EDT), I will be conducting a four-week series of tests using Comb Stereo. The broadcast will be aired on WRMI on 5850 kHz and will only be 15 minutes long. It will feature two minutes of “CNN” news by a computerized voice (sorry, I am doing this on-the-cheap!). Then, what follows is about 12.5 minutes of music encoded with Comb Stereo.

For you, the listener, to hear the Comb Stereo, you will need to record the broadcast to your digital recorder or SDR software and then play it back through your Windows PC using the instructions at the bottom of this announcement. I welcome feedback regarding such things as, 1 – I heard the broadcast and recorded it, 2 – I tried to setup my Windows PC but could not get the CSDecoder and Virtual Audio Cable to work, 3 – I got those things to work and opinions about what the stereo sounded like.

To repeat, you will not hear stereo unless you send your recorded audio file through the CSDecoder.

Do not expect FM Broadcast quality since Comb Stereo is a rudimentary form of creating two-channel sound. For instance, you may hear the stereo separation waiver a bit, or the sound stage image may wander, or a slight hollow sound at times. Sure, OK, but this is also a chance to hear stereo from a shortwave broadcast. So let me know your thoughts by sending feedback to [email protected] and I will tally up the results and post the findings here on the SWLing Post Blog.

Many thanks to Daz and Roseanna at Radio Northern Europe International for making the Comb Stereo available and to WRMI for the use of their transmitter.

KSKO’s Virtual Dance Party Moved to next week

If you missed hearing the Virtual Dance party by Paul Walker at KSKO which was scheduled to air this morning between 0300-0500 UTC, you weren’t alone.

I scheduled a notification to announcing that the date had to be moved due to a schedule conflict at KSKO, but I had the date incorrectly entered in the notice so it didn’t publish. Apologies to Paul and anyone who tried to tune in.

The Virtual Dance Party will be held on Saturday, March 27th 2021 from 0300 to 0500 UTC on 7570 kHz for the west coast and 7780 kHz for the east coast.

KSKO Christmas Special via WRMI Dec 24, 2020 starting at 2300UTC

I’ve just heard from SWLing Post contributor, Paul Walker, who now works at KSKO in McGrath, Alaska. He’s paid to broadcast KSKO 89.5’s special 2 hour all-Christmas music show on shortwave via WRMI’s 100,000 Watt 5950 kHz transmitter in Okechobee, Florida. The broadcast will take place from 2300 UTC on Thurs. Dec 24th to 0100UTC Fri. Dec. 25th (6-8PM EST). Paul mentioned that he’s doing this for fun and to share a little Christmas cheer from Alaska.

Thanks, Paul, and Merry Christmas!

Radio Northern Europe International Show 9

Many thanks to SWLing Post contributor, Roseanna, with Radio Northern Europe International who shares the following announcement:


Radio Northern Europe International Show 9 announcement

Hei all,

It’s our pleasure to announce RNEI #9 to you!

RNEI 9’s music features:

  • An artist introduction to a brand new group from the Faeroe Islands with their first song announced by Heidrik from the band
  • A candidate for Denmark’s Eurovision from 2020
  • A catchy Swedish song I really like at the moment
  • The return of Evelina and Zupermaria
  • Some traditional Icelandic and Samí music I think a lot of you will like
  • A Norwegian song from the 1970s that I recently discovered with a beep but no boops
  • Our first Estonian song to start of the dance segment
  • Fading into a Danish dance song to end off the show

RNEI 9’s digital experiments on Shortwave:

  • Easypal QAM16 7zip file transfer (of a website!) embedded into our interval signal
  • A few hidden experiments (Running JS8Call nearer the end isn’t a bad idea ? )
  • DominoEX22 embedded in the final song

Please note: On WRMI the broadcasts are 30 seconds shorter necessitating a shorter interval signal and therefore a shorter Easypal segment than the Channel 292 and Onda broadcasts. Expect potential changes e.g. QAM64 or lesser error correction modes. The version sent to World FM, Unique Radio and later On-Demand will be the “HQ” version, meaning it doesn’t have the Easypal (because it sounds nasty) nor does it use the Comb Stereo system.

TIAEMS for this month is really good complete with MFSK data and lots of great music!

As promised the Saturday 6070 kHz broadcast will be the first one on shortwave carrying the new show!

Our schedule is available here: https://rnei.org/listen/

QSLs are running massively behind schedule, we are very sorry, show first, website second and QSLs third at the moment making very little time to reply to them. We have got some ideas to speed up the process soon though!

Sending you all good wishes and hoping you can listen and enjoy the show,
Roseanna

This weekend: Brane Five broadcast on Channel 292 and WRMI

Many thanks to SWLing Post contributor, Linus Ruckstuhl (HB3XSQ), who writes:

I am a longtime reader of your blog. My brothers band (branefive.com just released their first rock song “Free the Animal in You” today on September 25th 2020. I got the idea to launch the song on shortwave in addition to the streaming services to celebrate it, especially because there are no physical discs and records anymore. The first broadcast at 0900 UTC on Channel 292 on 6070kHz already got us many Reception Reports. The song with the corresponding announcement will be rebroadcast by Channel292 this weekend from 25.-27.09.2020. The schedule is in the attachment.

Radio Northern Europe International now via WRMI

Many thanks to SWLing Post contributor, Roseanna, with Radio Northern Europe International who shares the following announcement:


Hello everyone,

RNEI has arranged a deal with WRMI to bring you our latest monthly show every Thursday at 1UTC on 5850 kHz (Wednesday night US time – just before TIAMS!)

Because these broadcasts are 1 hour long rather than our usual 30 minutes it allows us to have a little extra content we are calling RNEIX(tra).

[…]We will be broadcasting with similar processing to TIAMS so expect high fidelity sound in Comb Stereo ?

For our European fans:
New RNEI shows will always go out first on 6070 kHz Channel 292 before WRMI and any extra content will be available on demand.

We hope you can tune in and enjoy the show,

– Rose
