USCG Tests @ Various Frequencies from Kodiak, AK

May 19th log ... This test broadcast was loaded with Journaline, Weather Maps, etc, along with some binary file apparently. Signal strength wasn't quite good enough consistently, but at least the USCG is using an excellent configuration for only 800 watts or so. Keep it up. Get rid of WEFAX.

May 23rd log ... IIRC from the previous log, bit-rate was ~ 11 kbps.

@Tom, Interesting catch!
I added Kodiak on 8000, 9900 and 12100 kHz to the TX List this morning. Perhaps a dream (!) but I'll try to "receive" this broadcast here in Stockholm.

Terje,

You do have the USCG's schedule of frequencies through October of 2017, correct? I'm assuming so since you added these frequencies to DRM Log Plotter. You can find it on-line, e.g. DRMNA's group on Yahoo, I think. If you're currently in Japan, you should be able to receive it, but Europe would be another matter entirely. Thanks for adding the frequency to DRM Logger.

Marcel,

Good luck trying to receive these tests in Europe. I won't say it's impossible in Europe with perfect atmospheric conditions. I'm ~2,000 (?) miles from the transmitter at my location and the signal is generally quite weak. Also, I'd try a different time than 1600Z. Look at the times in my logs for possibilities. (UTC)

May 24th log ...

I think the USCG will switch to 5200 kHz today. The maximum logged SNR is a spurious result. The average SNR appears to be about 5 dB here. BTW, the actual bit-rate is 11.5 kbps.

Yes I found some interesting information at "WORLDWIDE DX CLUB Top News" about this project, including the frequencies. At present my QTH is Stockholm, so there is a slim chance that I will be able to see anything at all from Kodiak. And my next Japan visit is scheduled for November 2017 so that will be too late.

Thank you for starting the thread. I will check on your logs regularly.

I'm still regularly seeing the DRM signals from USCG here in NZ, but nowhere near strong enough for any decoding. Typical is the log from 8000 kHz this evening. On 5200 kHz I did get "USCG" decoded as part of the id a couple of days ago.

I'm off to Canada & the US in a couple of weeks for the solar eclipse, so hopefully will get a chance at better reception :-)

@Chris: Looking forward to your logs. Do you have their frequency schedule? If not I can mail it to you.

Hi Chris and all,

Even better in Lamont, Alberta. Envy you going there, Chris! At my location it is not possible to receive anything as the signal goes directly over the North Pole.

Another thing I have noticed is that when I am in Japan I never hear anything on 6 MHz from Europe, but when I'm in Stockholm I hear DPRK jamming in the 6 MHz band (among others on 6.600 MHz) on almost a daily basis.

I must talk to Mr KiwiSDR and suggest he adds DRM decoding ;-) Or at least a "stream the IF" option ;-)

Cheers, Chris
