During December's trip to the west coast of the Big Island the TP-DX
propagation was radically different from the watered-down version currently
being tolerated on the west coast. Instead of a few Asian big guns reaching
modest audio each morning there were wild DU-TP snarls every evening, along
with intense frequency fights between Asian co-channels on several frequencies.
Linked below are several extended mix recordings that were the most
memorable for the trip, all featuring two transoceanic stations fighting it out
at potent levels. If anyone is feeling bored with his MW-DXing hobby, I would
strongly recommend a trip to Hawaii as the ultimate, permanent cure!
1) 1440-Kiribati Vs. JOWF (Sapporo, Japan) These two stations were
equal-strength competitors from around 0800 UTC until Kiribati's sign off at
1007, carrying on a running battle for supremacy each evening. On December 19th
Kiribati switched its sign off time from 0936 to 1007, resulting in an 11
minute recording of the frequency fight (without a Kiribati sign off) starting
off at 0931 https://dreamcrafts.box.com/s/9eg4ip5jb5pvqsm6m5l1i0e5b05cs8gw
2) 621-Tuvalu Vs. China (Heilongjiang?) The pesky Chinese station was a major
problem for the exotic DU after 0800 UTC each evening, but North Korea's
Japanese service was almost equally troublesome. As if that weren't enough
Tuvalu came down with a distorted audio issue on December 18th, which continued
until I left. In this 8-minute recording China plasters the distorted Tuvalu
sign off routine at 1003 on 12-18, but Tuvalu manages to get the (garbled)
National Anthem out by itself. China quickly reclaims the frequency after
Tuvalu's sign off

3) 819-KCBS (Pyongyang) Vs. South Korean Jammer The North Korean "flagship"
station's ancient music gets pestered by the South's "Beehive" Jammer at 0921
UTC on 12-19. The jammer is apparently a low-powered transmitter designed to
cover only the Seoul metropolitan area, but its range included Kona, Hawaii on
most evenings https://dreamcrafts.box.com/s/luw8m6wabvlj4y6seylzwpx18vfavmw3
4) 1593-CNR1 (Changzhou, China) Vs NHK2 Synchros Despite running 600 kW the
Chinese station could never quite put away the pesky Japanese 10 kW duo. In
this typical recording at 1003 on 12-20 CNR1 builds up some potent strength but
the NHK2 English lessons never go away

5) 909 Mix (All UnID) One of many potent "mystery mixes" from the Kona trip,
this recording at 0956 on 12-18 features multiple Chinese voices, including
various children chanting at an S9 level for the last two minutes-- maybe CNR6
and others? https://dreamcrafts.box.com/s/3f746ufu3x0gjiwe2fi05j2jo3pkav4d
