Re: [IRCA] Cook Islands Ultralight DXpedition-- Asian TP-DX Loggings (Part Two)

Gary:


Gray line propagation is semi-defined here: http://dx.qsl.net/propagation/greyline.html .


While a name is just a name, I would guess you had no gray line propagation (nor close to it) but were simply the victim of decent sunset conditions.

Subject: [IRCA] Cook Islands Ultralight DXpedition-- Asian TP-DX Loggings (Part Two)

     This is the concluding segment of the Asian TP-DX loggings made on Aitutaki island in the Cook Islands chain (2,600 miles due south of Hawaii) from April 9-13 using a 7.5 inch loopstick C.Crane Skywave SSB Ultralight and a 5 inch "Frequent Flyer" FSL antenna.

     As mentioned previously, phenomenal gray line propagation during the sunrise sessions enabled the modest gear to perform like gangbusters, resulting in reception of MW stations in India, Bangladesh, Mongolia and Cambodia-- all at distances greater than those from typical west coast DXing sites. The gray line propagation also tended to shut down Japanese signals, and take out most of the Korean stations as well. In combination with extensive ANZ co-channel QRM, this limited the number of Asian stations received.


972  HLCA   Dangjin, S. Korea, 1500 kW   The South Korean big gun played the part on most mornings, including this S9+ Korean female speech at 1631 on 4-12  https://dreamcrafts.box.com/s/gynxilf8rpe762f0y5wbj85k0krh1dvb

981  CNR1 Synchros   Changchun/ Nanchang, China, 200 kW/ 200 kW   The first of three CNR1 frequencies which usually produced strong signals, this music // 1377 was received at 1624 on 4-12  https://dreamcrafts.box.com/s/tybl0tglmfqkec7u2u1udhgncd4sc5d5

1377  CNR1 Synchros  (Various)   Overall this was not only the strongest Chinese frequency on the band, but was the strongest Asian station on the band as well.  Awesome S9+ signals were typical each morning, as with this male speech and music at 1622 on 4-12  https://dreamcrafts.box.com/s/5eh6zami9876vajyjjfoaqz764lcmo1a

Another potent signal from this Chinese blaster at 1640 on 4-12  https://dreamcrafts.box.com/s/8jlbyscbxe4i8ed1n4admt01f66gt7jt

1431  Mongolia (Relay Station)   Choibalsan, Mongolia, 500 kW   This station was easy to receive on the first attempt, with very little competition on the frequency. It typically managed an S9 signal after 1630 daily with the BBC's Korean service, which seemed to be broadcast during the peak sunrise enhancement time in Aitutaki's ocean-boosted propagation. Here is BBC's Korean male announcer at an S9 level at 1632 on 4-11, with the BBC interval signal at 47 seconds into the recording  https://dreamcrafts.box.com/s/bfl4ohbfmhf9fdvfa6mx6jnxapaayk4a

The Mongolian relay program prior to 1630 was also in Korean, with this female Korean speech at 1627 on 4-11  https://dreamcrafts.box.com/s/5892chd20zbxs3w7r1q1f2qx39f6l7gm

1566  HLAZ   Jeju, S. Korea, 250 kW   A very poor signal was typical during this trip, with the Chinese service barely showing up under 3AW and two other DU English stations (probably 4GM and Norfolk Island). Whenever 3AW was in a fade it had a chance, since other two co-channels were running very low power. Here is the latter situation, with the weak Chinese barely audible under the DU English snarl at 1641 on 4-12  https://dreamcrafts.box.com/s/hysvrh4f7i8u16f3740ch5azam0iervx

1593  CNR1   Changzhou, China, 600 kW   This was another Chinese blaster, with S9 signals typical every morning. Here it was at 1641 on 4-12 with male Chinese speech and music // 1377  https://dreamcrafts.box.com/s/unn7d4h3wa9ro7g7wespunkqeaay6f6e


73 and Good DX,
