KBRW 680

Post by John Faulkner, Skegness » 13 Jan 2016 15:21

After Jurgen posted a message to the Yahoo MW group, yesterday evening, regarding his reception of KBRW Barrow, Alaska, I made a screen grab of the carriers I received here, later in the evening. Here's the grab:

680 12-01-15 (Evening & Early Morning) https://app.box.com/s/5dxaphwb519uk3w7p7a0krtifqguugs7

The smeary carrier might just be KBRW - the smearyness coincided with auroral conditions. The carriers weer not strong enough for audio.

The rough line at the bottom was noise returning. The greyed-out area is just hiding carriers from other frequencies to avoid confusion.

So, this afternoon, I thought I would check for carriers again. THREE carriers are currently present. The strongest one is coming in at -115 dB, so almost strong enough for audio on my (presently) VERY quiet medium wave. I think this one is just a navigational beacon. Three of these are present on 680 anyway. The offset is 679.680.002. The other two carriers, both much weaker, are at 680.009 and 680.024. (Calibration checked again the BBC on 909 kHz.)

I don't see carriers on 850 and 970, two other Alaskan carrier regulars from the past, so maybe the 680 carriers are only navigational beacons, but 680 is definitely worth checking.

I hear very weak murmurs of YL speech on 680 now. It sounds exactly like the YL on the audio. I can match the speech intonation. I hope this gets stronger. Looks like this is 100% KBRW.

I had to go out this afternoon, so I left Perseus monitoring the carriers on 680. This is this afternoon's result.

Looks like KBRW is the carrier in the centre - and it's peaking up now. I suspect that the lower carrier might be a navigational beacon. Isn't there a Russian beacon there? Anyway. Great to hear Alaska again, albeit painfully weakly.

The carrier itself backs this up as KBRW are known to be on 680.000 exactly.

Thanks Tim.

Isn't it crazy? I struggle to hear easy east coast stations, then in comes Alaska! The disappearance of 675 is going to make things a lot easier now though. Keep a check on this one.

I'll eat my hat if it makes it through my local noise these days, 2008 (?) was the last time I had it , then a couple of years ago I got KUMU 1500 totally out of the blue one afternoon

never say never I guess!

just remembered by new improved set up, there may be hope,
now watching 680 with maximum amplification nothing now but i'm slightly too late for today anyway

local interference signed on at 16:30 producing closely spaced carriers, no idea of the cause

Oh no. I am just posting to say that KBRW's carrier is fractionally below audio level now. This is better, earlier than yesterday. I hope your noise disappears very quickly.
