Video: Requiem for Radio broadcast via four frequencies, four receivers

The Requiem For Radio QSL Card (Source: RFR Facebook)

I received a number of messages from Post readers who logged one or more of the simultaneous Requiem For Radio broadcasts. Many discovered that each frequency of the broadcast was actually a separate track of the piece.

Indeed, SWLing Post contributor, Shelby Brant, posted the following comment yesterday:

Listening right now, 11580, 9690, 9620, and 5130 are on, but nothing on 6850. To get the most out of this you really ought to have a receiver on all the frequencies at the same time, because each station is broadcasting something slightly different, but if you listen to all at the same time, they go together.

Later, Shelby added:

Here’s a link to a very impromptu video I put together of how I was listening to the broadcast, I managed to gather up 4 receivers (this was after I posted earlier) and tuned them to the 4 active frequencies. Part way through I turn the other three receivers down and tune to the individual stations one at a time to give an idea of what the 4 sounded like on their own, then it goes back to all 4 together again for the end of the video

Very –VERY- cool, Shelby! Amazing! Thank you for sharing!

And what a unique listening opportunity this presents us (thank you, Amanda Dawn Christie!).

If you missed the last on-air performance, you still have two more chances to catch it.

    I found this very interesting. Does anyone know if the original was recorded in multi-channel and then separate channels distributed to each of the radio stations?

    I set up my SDRPlay radio to record 3MHZ and was able to have three receivers running on 11580, 9690 and 9620. I could toggle the receives on-off and hear the effect. Tonight, I recoded the entire hour broadcast, so I could go back and play various combinations of the three stations. I wasn’t able to receive the 5130 station very well, and heard nothing 6850.

    I agree that they seemed to be in sync – I would have thought there would be transmission delay effects.

    Man, wish I’d checked in on the blog earlier. I came across this while waiting to run some errands this afternoon and was totally perplexed by it. I heard it first on 11580, then 9690 and 9620 and didn’t what the high holy heck was going on! A pretty cool experiment, though. If I’m around when it airs later today I’ll try to line up all my radios. I’ve got four I can sit side by side, if I don’t forget!

    Tonight I tuned in to the Requim for Music SW program using four different receivers and four different antennas I have hooked up each tuned to a different frequency. The sound was amazing indeed. That’s the first time I’ve ever had all four units on at the same time. The blending of the sounds was incredible, there was no delay that I could pick out between the frequencies or receivers processing the sound.
    As I continued to listen I was reminded of Pink Floyd Dark Side of the Moon music, very nice.
    I contacted Amanda earlier today and she confirmed QSL will be sent for e reception report toh ER e mail address found on her website.
