-----------------------------------


** BOLIVIA 4781.5v, *0959, (p) R Tacana, Tumupasa, Aug 15. Presumed. 
Transmitter switched on at *0959 on measured 4781.46, drifting upward 
rapidly. Transmitter off at 1016 and then back at 1027 UTC, but only 
threshold audio noted by R Coatán 4779.96 *1030 sign-on with massive 
signal. (Jordan-TN)

4796.36, *1000, (p) R Mallku, Uyuni, Aug 15. Presumed per LA SW Logs. 
Transmitter switched on at *1000 on measured 4796.38 kHz. Due to heavy 
CODAR, no usable audio until 1030 and then only able to determine 
Spanish language, and transmitter had settled down to 4796.36 kHz. 
Buenas Nuevas slop at *1056 along with CODAR made signal totally 
unusable, even in LSB. (Jordan-TN)

** BRAZIL 4775.04, *0759, (p) R Congonhas, Congonhas MG, Aug 15. 
Presumed. Transmitter switched on at *0759 and measured on 4775.02 kHz. 
Only threshold audio at best around 0936 'sunrise at transmitter' 
enhancement, at which time the transmitter had settled on 4775.04 kHz. 
(Jordan-TN)

4785.07, *0844, (p) R Caiari, Porto Velho RO, Aug 15. Presumed. 
Transmitter switched on at *0844, but no audio heard until beginning 
around 1020 UTC with Portuguese talk by male announcer with audio 
slightly improving until vocals at 1027 'sunrise at transmitter' 
enhancement. Fading back down by 1028. Poor in static with mild CODAR. 
(Jordan-TN)

4805.00, *0955, R Dif do Amazonas, Manaus AM, Aug 15. Transmitter 
switched on at 0932 and transmission started at *0955 with sign-on 
announcements by man. No definite ID heard but many mentions of Brazil 
and Amazonas, various phone numbers mentioned, etc. Great signal but not 
a match for CODAR. (Jordan-TN)

4845.23, *1031, Ondas Tropicais, Manaus AM, Aug 15. Transmitter switched 
on at 1002 with strong S9 carrier with 1004 'sunrise at transmitter' 
enhancement. Signal levels were still good when transmission began at 
1031 with a brief sign on ID by man mentioning Ondas Tropicais and 
Brazil, but unable to catch entire announcement due to UTE on 4845 
transmitting at that moment. Directly into back to back contemporary 
vocals, with no announcements heard, lasting until 1100 by which time 
audio had faded to unusable levels. (Jordan-TN)

4925.03, *1019, (p) R Educação Rural, Tefé AM, Aug 15. Presumed. 
Transmitter switched on at *1019 with announcements in Portuguese by man 
and woman, possible ads or promos. Fair signal from sign-on which was 4 
minutes from sunrise at the transmitter, but massive CODAR QRM here. No 
ID heard. (Jordan-TN)

** GABON 4777.00, *0456, R Gabon, Moyabi Aug 15, Transmitter switched on 
at 0456 and French programming beginning at 0459 with repeated 
announcements by woman over musical instrument. News read by man from 
0501 to 0511, then back to female announcer playing lively African 
vocals between announcements and TCs with many mentions of Radio Gabon. 
Initial noisy S7 signal rapidly improved to very good S9+10 by 0509 
sunrise at transmitter and lasting until 0523 before slowing starting to 
fade. The carrier did not drop below the noise floor until 0757 UTC. 
(Jordan-TN)

** GUATEMALA 4779.96, *1030, R Coatán, San Sebastian, Aug 15. Sign-on 
with NA, the canned ID at 1036, 'Buenos dias.... Estereo Coatán..' into 
organ music. (Jordan-TN)

4799.77, *1058, R Buenas Nuevas, Aug 15. *1058 sign-on with S9+10 
signal. Children singing, announcements and ID by woman then man. Even 
with a S9+10 signal, CODAR ruined it. (Jordan-TN)

** INDONESIA (IRIAN JAYA) 4789.98, 0835, RRI Fak Fak, Aug 15. Carrier 
first noticed at 0835 just above the noise floor and rising to S5 by 
0917 sunrise at the transmitter. By 1100 UTC the signal was at S6 levels 
with program consisted a wide variety of pop style songs with a female 
announcer speaking between selections. Heavy CODAR QRM on the frequency 
throughout. (Jordan-TN)

** INDONESIA (IRIAN JAYA) 4869.93, 0741, RRI Wamena, Aug 15. Very 
tentative. Spotted a very weak carrier just above the noise floor at 
0741 and slowly climbing to S3 by 0800 and at S5 by 0846, which is 
sunset at Wamena. Signal held steady at this level until rising to S6 
levels about 20 minutes before 1128 sunrise here in Memphis and stayed 
at this level until the recording ended at 1200. Very noisy and only 
threshold snippets of audio from 1100. (Jordan-TN)

** MALI 4835.58, *0537-0800*, ORTM, Bamako, Aug 15. Transmitter switched 
on at 0537 with S5 signal. Hints of threshold audio appearing around 
0610 and signal peaking at  to S7-8 levels with 0620 'sunrise at 
transmitter' enhancement lasting only about 10 minutes. A very nice 
extended ethnic vocal featuring a female singing over stringed 
instruments before audio rapidly faded to unusable levels. Signal still 
above noise floor at 0800* sign off. (Jordan-TN)

** MAURITANIA 4845.15, *0703, R Mauritanie, Nouakchott, Aug 15. 
Transmitter switched on at *0703 with news in progress in French. S6 
signal, significant static and strong UTE QRM on lower side. Sign-on was 
too late for 0646 'sunrise at transmitter' enhancement,  Good 
modulation, so audio was at decent levels despite the noise, and 
transmitter downward while warming up from 4845.19 until settling at 
4845.15 by 0715. (Jordan-TN)

** MéXICO 4810.00, 0900, XERTA, México City, Aug 15. Same new age 
synthesized tune played over and over until SDR-14 recording ended at 
1200. No announcements at all, just this boring tune non-stop. (Jordan-TN)

** NIGERIA 4769.97, 0416, R Nigeria, Kaduna, Aug 15. Transmitter 
switched on at 0416, but only threshold audio detectable by 0428 due to 
poor modulation despite S6 to S7 signal. Signal suddenly rising to S8-9 
with improved audio exactly at 0513 'sunrise at transmitter' enhancement 
lasting until 0523 before beginning to deteriorate, with news type 
monologue by male in presumed Hausa. Audio back to barely threshold 
levels by 0540 and carrier finally dropped below noise floor at 0730. 
(Jordan-TN)

** PERU 4754.97, *0917, R Huanta 2000, Huanta, Aug 15. Noticed this one 
signing on at *0913 on 4755.01 kHz, but dominated by Campo Grande, 
Brazil. Checked back at 1054 'sunrise at transmitter' enhancement and 
all alone with many mentions of Huanta and Peru by male and female 
announcers and lots of sound effects, although overall poor due to 
static. Transmitter drifted downwards until finally settling on 4754.97 
around 1035. (Jordan-TN)

4774.96, *0953, R Tarma, Tarma, Aug 15. Presumed. Transmitter turned on 
at on at 0953 and measured at 4774.98. No audio noted until almost 1100 
and barely improving to threshold audio by 1115-1118  despite greyline 
between Tarma and Memphis, at which time the transmitter had stablized 
around 4774.96 kHz. (Jordan-TN)

** SWAZILAND 4774.97, 0400, TWR, Mpangela, Aug 15. Religious vocals and 
instrumentals, poor to fair with static. (Jordan-TN)
