6945 KHz XFM Shortwave C-QUAM AM Stereo test

(1/3) > >>

Kilokat7:
Signed on just after 0200 UTC with test tones at various frequencies, then XFM ID with "C-QUAM AM stereo test transmission" followed by The Cars "Moving in Stereo".  S5 signal, static crashes making C-QUAM decode a little challenging but I'm locked onto the 25 hz pilot tones and currently listening in stereo via Perseus SDR + SoDiRa.  Will post a recording later tonight or tomorrow evening.  Thanks for this test XFM!



As promised, here's the complete reception as it sounded here:

This extra LED on my receiver keeps flashing on and off...

With the hardware decoder on a TS-140S, I have pilot about 50% of the time .  Thought there was separation during the Cars piece when you got above S9.  Kind of eerie listening and just getting a feel for this.  It's noisy tonight with choppy fades.

The Meduci decoder in the TS-140S seems to lose pilot easily in a fade.  I am in and out of lock with fading, and it is sometimes a pronounced difference, sometimes it is more subtle.  But it is stereo!

Reception here was around S8-S9, and that would have been enough to keep pilot lock here, I feel.  Problem was the very choppy fades down to S5.  I also noted some unlocking due to noise.

Congrats redhat!  small steps...

Danoman:
Very good audio here in "normal" am mode.
S9 +10 peaks with brief fades to S7.

Zoidberg:
7/23/12, 6945, 0230z: Music just barely audible, not enough to ID anything so far.

lightkeeper:
Signal is fair on west coast...up to S5 but modulation level is very low, hard to make out the music
