Thanks for keeping the lights on at HFU Chris! I scribbled an hour long STERNRADIO again on the waterfall today for the daily screenshot.
Has anyone else giving the stereo stuff a try? Both CQUAM and SAS modes on KiwiSDRs seem to sound identical to me when it comes to L vs R separation, which is what I was hoping for.

Yeah, they seem the same to me. You could do an over the air (OTA) test: 15 seconds of single-tone left+right, then the same but left only, then the same of right only, to judge the separation.
Also noticed you are on 6966.666, because....well, you know.
2104 - TX off.

Excellent signal. Need to go mow, but wanna try the stereo on SDR to see how it sounds
<moments later> Oh well, guess it signed off in the couple of minutes between the time that I tuned in, ran to the computer & logged it, and checked an online SDR

Thanks for the report and noticing...the proper frequency! ;)
I did do drop outs like that a few times with either channel. The effects on the waterfall, those were OBVIOUS! Here is the with the CQUAM decoder, if I HARD drop a channel, and this is a flaw of CQUAM, as it fades down it'll eventually POP into a mono signal! That's one of those things you can't really *fix* about it. Just the nature of the math behind it. Most content isn't quite that...STEREO. The SAS/ISB Stereo decoders handle the situation as you'd expect and just left the weak channel disappear and that's OBVIOUS with the cans on :)
