Re: [IRCA] An unusually good TP morning?



Hi Again Brian, 
 
Thanks for posting this morning's TP-DXing MP3's from Arizona. Arizona's propagation from Asia is usuallyÂtrickierÂthan what we enjoy here in Washington state and BC, so the sunrise enhancements that show up hereÂdon'tÂoften make itÂso far south.ÂÂ 
 
<<<ÂÂ Unattended recordings with my software defined radio (SDR) had yielded progressively stronger signals for presumed HLAZ 1566 kHz out of Korea over the previous three mornings, at best being marginal audio. Propagation went up a significant notch today and the star of the morning was HLAZ. As usual, this is more about getting the audio signal at all as opposed to getting âarmchairâ quality.ÂÂ >>> 
 
Your first and second MP3's (at 1052 and 1131 UT)Â are fromÂ1566-HLAZ's Chinese service, with Chinese female speech at a fairÂlevel on the second MP3. As usual, the Perseus-SDR recordings sound almost high fidelity, compared to Ultralight radio reception in the 1 kHz DSP mode. 
 
<<<ÂÂ The second best station was presumed JOUB on 774 kHz out of Japan. The audio was pretty weak, but I did hear a voice at 3:46am (1046UT), before I started recording. The following recording isnât much, but if you listen carefully you can hear the time pips leading to the top of the hour at 5am MST/12UT, under splatter from adjacent domestic stations:ÂÂ >>> 
 
The 3 + 1 time pips on your 774 MP3 are typical of the Japanese NHK stations (like JOUB) at the top of the hour. There are other networks that use the 3 + 1 pips (like theÂKoreans on 558, 603 and 972) but Chinese stations (and the New Zealand RNZ network) use 5 + 1 time pips. 
 
1566-HLAZ also is capable of huge signals here in Puget Sound, well before sunrise. This MP3 of HLAZ's Japanese service (at a near meltdown level) was made last Saturday at 1344 UT on my modified Ultralight radio and 15" FSL antenna http://www.mediafire.com/view/5yfi9h97l87s987/1566-HLAZ-1344z022815CCSW.MP3

Ok, I had a chance to put a few audio snippets up on my blog: 
https://azswdxing.wordpress.com/2015/03/04/log-am-bcb-march-4th-trans-pacific-reception/ 

Nothing spectacular, but much better than usual here, especially for 
1566-HLAZ. ÂI'm still looking for an intelligible TOH identification from a 
TP station, but I did get time pips from presumed 774-JOUB.
