For what it's worth, when I worked on Media Network one of the RNW
technicians told me that he a special setting for my voice. When comparing
the sound of my recorded voice when he was on duty to the sound when working
with other technicians, there was a distinct improvement.
I remember, too, visiting TWR Bonaire (Glenn was on the same visit) when
they demonstrated how the sound processing could be asdjusted from telephone
quality to nearly hifi according to what material they were broadcasting.
Unfortunately, too many international broadcasters (and many domestic ones)
pay scant attention to audio quality.

If he were not referring to a ``self-proclaimed expert`` or ``guru``, I
would
think he was talking about me, since I have made just such comments about
phoning-in! But I have never proclaimed myself to be any such thing. Where
would he get that idea?
OK, tnx for the explanation, but then other announcers` voices must be
processed very differently since they are of higher fidelity, which with
RHC`s
huge signals is certainly a benefit rather than a detriment (Glenn Hauser,

** AFGHANISTAN [non]. An mp3 file of R. Solh music, 29 minutes, 6836 kb, 32
kbps, 22 kHz, recorded in late January at 1419-1459 UT on 15265 via UK, with
announcements removed, is now available for all to enjoy at
http://www.w4uvh.net/sohl0801.mp3 If anyone can identify any of the music,
please let us know as it would be nice to obtain CD quality recordings of it.
The second piece is partly in English (Glenn Hauser, OK, DX LISTENING DIGEST)
** EGYPT. Altho I was hearing R. Cairo via ABZ site on 6290 some minutes before
2400 UT Feb 9 as I tuned by, at 0005 Feb 10 I found a strong carrier, but
extremely weak and distorted modulation on 6225, nothing on 6290. 0000 is when
the Arabic service is scheduled to switch 6290 from ABZ to ABS site, the latter
with its terrible modulation, as we have noted before, and also with a
considerable overlap between the two sites. This time on 6225, there was some
yelling and applause, but the modulation so weak and distorted I could not even
be sure of language, let alone pull a definite ID, but circumstantially it
appears that Cairo has moved from 6290 to 6225 for the service after 0000,
which remains a total waste. We shall hear subsequently whether this was a
mistake, fluke, or permanent change (Glenn Hauser, OK, DX LISTENING DIGEST)
** MEXICO. R. Educaci?n, 6185, 0001 Feb 10, sign-on as SW station XEPPM on
6185, with current date and time, power 10 kW, live announcement in Spanish,
and then the same in English --- a good time for monolinguals to DX them tho
they occasionally throw in English IDs elsewhen. It`s a shame they don`t put a
little more effort into some real English programming.
Show following sounded like ``Su casa y otros viajes`` or was it ``carta`` but
neither makes much sense. Program schedule
http://www.radioeducacion.edu.mx/carta_programa.pdf does not match, just
showing ``RFI`` at 6 pm Saturday. Not clear if besides the sign-on, the SW
programming is partially or totally identical now to MW 1060 XEEP, but no sign
of a separate SW sked on the website.
Nor can I any longer find detailed playlists minute by minute they used to have
on website bookmarked at http://www.radioeducacion.edu.mx/HojaProg1.html nor
any trace of it on the site map, tho they have added a lot of text material and
the latest fad, podcasts. Maybe playlists are now for Registered Users only?
But no explanation of what benefits RU`s get! (Glenn Hauser, OK, DX LISTENING
DIGEST)
** VENEZUELA [non]. Sunday Feb 10 made my habitual check for ``Al?,
Presidente`` frequencies via Cuba, vs mainstream RHC programming. At 1426 found
the A,P lead-in show from RHC, ``Mundo Siete``, week in review, both on 11680
and 11670! 11670 was much weaker than 11680, and the two were out of synch, so
from two different transmitter sites. Meanwhile, 11875, which had been one of
the A,P Sunday-only channels, was missing, with only a weak WEWN audible.
Apparently, RHC finally got our message that the 14-15 hour was colliding with
WEWN and moved that transmitter to 11680. However, at 1514 recheck, 11875 was
on, after WEWN had left. I wonder if they announce such a frequency change
around 1500? A,P also on // 13750 very strong, making a reverb with 11680. Also
on 13680, but barely detectable in skirts of CRI via Sackville 13675. At 1456,
17750 was starting to fade in with WYFR dominating, trace of Cuba.
Meanwhile, mainstream RHC was as usual on 11760, 11805 and 12000 around 1430,
closing around 1500; I noticed that 11805 was off the air before the others had
finished.
I was already hearing the blustery voice of Hugo Ch?vez Fr?as at 1435, so
apparently he was rarin` to go. His timezone change may have affected his
habitual startup time, tho it would logically be later in real time, not
earlier (Glenn Hauser, OK, DX LISTENING DIGEST) ###

Content-Type: text/plain; charset=iso-8859-1
Arma formidable de la Revoluci?n
Fundada por el Che hace 50 a?os, desde entonces ha mantenido su ascendencia y
prestigio en el pueblo.
http://www.bohemia.cubaweb.cu/2008/02/06/historia/2-radio-rebelde.html
Abrieron la trasmisi?n con el Himno Invasor. Acto seguido, se oy? la
identificaci?n de la emisora: "Aqu?, Radio Rebelde, la voz de la Sierra
Maestra, trasmitiendo para toda Cuba, en la banda de 20 metros diariamente a
las cinco de la tarde y nueve de la noche, desde nuestro campamento rebelde en
las lomas de Oriente. Director: capit?n Luis Orlando Rodr?guez."
Fidel convoca a la huelga general revolucionaria a trav?s de las
ondas de Radio Rebelde El t?cnico Eduardo Fern?ndez hab?a colocado la antena
entre dos arbustos. "Era para la banda de 20 metros -confesar?a a?os despu?s en
una entrevista-, y eso limitaba la cuesti?n para poder salir en otra banda...
La banda de 20 metros no es propia para escucharse en Cuba, se utiliza m?s bien
para comunicaciones de larga distancia. Por lo que, seguramente, se escuchaba
en Pinar del R?o, pero lo que era en Santiago de Cuba y las provincias m?s
cercanas, no... En el extranjero s? entraba perfectamente."
Instalaron la emisora en la sala de una casa abandonada, ubicada cerca de
Altos de Conrado. Situaron debajo de un tronco la planta el?ctrica, de un
kilovatio, la cual alimentaba el transmisor, un tocadiscos y el bombillo que
colocaron para que los alumbrara. El m?dico rebelde Julio Mart?nez P?ez, quien
andaba por la zona, al ver montar la emisora, exclam?: "Esta es la civilizaci?n
que llega a la Sierra".
La primera transmisi?n oficial se realiz? el 24 de febrero de 1958 y dur?
alrededor de 20 minutos. Los locutores en aquel primer programa fueron Orestes
Valera y Ricardo Mart?nez; luego se incorporar?an otros compa?eros a la
locuci?n, entre ellos Violeta Casal y Jorge Enrique Mendoza. "Se hizo menci?n a
los combatientes ca?dos en el combate de Pino del Agua -recordar?a Orestes-,
algunas acciones, escaramuzas y emboscadas de la columna del Che y se ley? un
editorial dedicado a la fecha del 24 de febrero de 1895."
En uno de sus primeros comentarios, la nueva emisora definir?a su l?nea
editorial. "Radio Rebelde surge para contribuir a la orientaci?n necesaria y
?til del pueblo en esta hora decisiva de la Patria, para dar a conocer la
intenci?n verdadera de esta lucha y fomentar y practicar la virtud donde quiera
que se le encuentre. Y para juntar y amar y vivir en la pasi?n de la verdad
como dijera Mart?."
Una tradici?n revolucionaria
Durante la rep?blica neocolonial, los patriotas cubanos utilizaron la radio
como instrumento eficaz para la divulgaci?n de sus ideas. Constitu?a un medio
id?neo, tanto por su inmediatez como por ser mucho m?s econ?mica y asequible a
las masas analfabetas.
Che, m?ximo impulsor y fundador de la emisora. A su lado, en la
Sierra Maestra, el periodista uruguayo Carlos Mar?a Guti?rrez
La radio fue escenario de las campa?as de Eduardo Chib?s contra la corrupci?n
de los gobiernos aut?nticos, de los combates del intelectual comunista Salvador
Garc?a Ag?ero contra la discriminaci?n racial y otros males de la neocolonia,
de las luchas del sindicalista Jes?s Men?ndez por el diferencial azucarero y
otras demandas obreras arrancadas a la patronal.
El entonces dirigente de la Juventud Ortodoxa, Fidel Castro, tambi?n us? este
medio en sus denuncias contra el Gobierno de Pr?o. Luego, cuando encabez? a la
Generaci?n del Centenario en las acciones del 26 de julio de 1953, ten?a entre
sus planes la toma de una emisora radial desde donde se transmitir?a la ?ltima
alocuci?n de Chib?s y el Manifiesto del Moncada para convocar al pueblo a la
lucha contra la tiran?a.
No es de extra?ar que el Jefe de la Revoluci?n coincidiera con el Che en la
necesidad de una emisora radial que, desde la Sierra Maestra, divulgara el
ideal y los triunfos de los rebeldes.
"Recuerdo que el Che se tom? inter?s y realiz? esfuerzos para crear Radio
Rebelde -afirma Fidel-, en un momento en que nosotros comenz?bamos a disponer
de un territorio m?s o menos estable. As? la primera ubicaci?n de Radio Rebelde
fue en las proximidades del campamento que el Che ten?a en la zona de La Mesa."
La cadena de la Libertad
Luis Orlando Rodr?guez, el primer director de Radio Rebelde
Ante las persecuciones de la tiran?a batistiana, muchos revolucionarios
cubanos hab?an tenido que exiliarse. En Venezuela, a principios de 1958, ya se
hab?an organizado en una filial del Movimiento 26 de Julio. Seg?n testimonio
del historiador Francisco Pividal, una noche, un radioaficionado vinculado al
Movimiento interrumpi? con sus gritos la reuni?n del ejecutivo de la Secci?n
Venezuela. "La cog?, la cog?, ya me empat? con la Sierra."
"Era la primera vez que se captaba Radio Rebelde -afirmaba Pividal-, aquella
noticia paraliz? la reuni?n y provoc? que, desde entonces, comenz?ramos a
prestarle una gran atenci?n a la divulgaci?n de informaciones que trasmit?a la
Sierra. Empezamos a pensar en una difusi?n mayor de los programas de Radio
Rebelde. Consider?bamos que las retrasmisiones ser?an impactante, tanto en
Venezuela como en el resto de Am?rica Latina."
Se hicieron contactos con Radio Rumbos y luego, con Radio Continente, y se
envi? luego a un compa?ero a Colombia para que visitara al administrador de la
cadena Caracol. "Indudablemente, a esas emisoras les interesaba retrasmitir los
programas de la Sierra -apuntaba Pividal-, ya que con ello aumentar?a el n?mero
de oyentes. Y lo mismo pas? en Cuba, que a las once u once y media de la noche
todo el mundo estaba pendiente de la onda corta para escuchar Radio Rebelde."
En Ecuador tambi?n se logr? una coordinaci?n con emisoras de ese pa?s. En
opini?n de Pividal, "lo dem?s fue casi sin necesidad de mayores conexiones,
comenzaron las emisoras de Sudam?rica a copiar a Radio Continente, Radio
Caracol y La voz de Quito, y se form? lo que se llam? La cadena de la Libertad".
Rebelde multiplicada
Orestes Valera (extremo izquierdo) junto a sus compa?eros de
locuci?n Violeta Casals y Jorge Enrique Mendoza Despu?s del fracaso de la
Huelga del 9 de Abril, Fidel dio instrucciones para trasladar a la emisora
hacia la regi?n de La Plata. "Por eso Radio Rebelde estuvo en el centro de
todos aquellos combates -afirm? Fidel al referirse a los d?as de la ofensiva
batistiana contra el basti?n rebelde de la Sierra Maestra-, en determinados
momentos las tropas (enemigas) que avanzaban por el sur llegaron a cuatro
kil?metros de Radio Rebelde y las tropas que avanzaba por el norte llegaron a
tres kil?metros."
"Radio Rebelde est? en el aire durante toda la ofensiva batistiana -a?adi? el
Jefe de la Revoluci?n-, (la cual) comienza en el mes de mayo (1958) y cobra
fuerza durante todo el mes de junio. Los combates que tuvieron lugar con motivo
de esa ofensiva duraron m?s de 70 d?as."
A lo largo del ?ltimo semestre de 1958, ya derrotada la ofensiva, a trav?s de
la emisora rebelde se trasmitieron todos los partes sobre la situaci?n militar
y los combates librados en los distintos frentes. Cuando diversas columnas
partieron de la Sierra Maestra con misiones a cumplir en otras provincias,
ten?an una informaci?n exacta de todos los acontecimientos de la guerra.
"En un momento dado no existi? ya solo Radio Rebelde -ha recordado Fidel-, en
el Segundo Frente se organizaron 18 emisoras de radio que estaban en sinton?a
con RR. En la zona del Tercer Frente, tambi?n. Y se convirti? en un principio
de que cada una de las tropas que establec?a un frente, procuraba levantar su
emisora."
El primer d?a del triunfo
En los d?as finales de 1958, la emisora radicaba ya en Charco Redondo, en la
hoy provincia de Granma. Las trasmisiones eran mucho m?s precisas y se
extend?an hasta Argentina. Seg?n testimonio de Euclides V?zquez Candela, "me
parece que fue el 29 de diciembre, (cuando) lleg? el comandante Paco Cabrera,
quien muri? en Venezuela (en un accidente, durante la visita de Fidel a ese
pa?s, semana despu?s) y nos dijo: ?Por orden de Fidel, empaqueten la planta,
s?banla al cami?n y vamos para Palma Soriano?. Esa noche, despu?s de las
trasmisiones, nos fuimos para all?. En Palma, hubo problemas con la estaci?n y
la noche del 31 de diciembre no sali? al aire la planta".
"Est?bamos durmiendo en una casa de Palma (Soriano) -rememoraba Orestes
Valera- y un compa?ero, no recuerdo qui?n, nos despert? y nos dijo que Batista
se ha ido... Por la ma?ana se hizo la transmisi?n desde la casita aquella...
Participamos todos: Violeta, Mendoza, Guillermo P?rez, Boffill, Eduardo,
Ricardo Mart?nez y yo."
"Aqu? Radio Rebelde, todo el mundo en sinton?a con la Cadena de la Libertad,
esperando declaraciones importantes del Comandante Fidel Castro, nadie se deje
confundir por el golpe de Estado, por los sucesos por la hu?da del tirano,
esperen las declaraciones del Comandante en Jefe."
A trav?s de sus ondas radiales, Fidel convoc? la huelga general
revolucionaria que neutraliz? las maniobras de la embajada yanqui, con las que
se pretend?a frustrar con una conjura palaciega la victoria del pueblo. En ese
momento, en opini?n del Comandante en Jefe, "Radio Rebelde demostr? toda su
fuerza, todo su valor y toda su ascendencia y su prestigio en el pueblo".
Fuerza, ascendencia y prestigio que su destacado colectivo de trabajadores ha
mantenido en estas cinco d?cadas de Revoluci?n en el poder.

Sometimes they mentions "Radiocomunicaci?n Roco" what could generates doubt,
and should sounds like "Radio...Co", "Radio Eco". Radiocomunicaci?n Roco maybe
is the name of the owner of R. La Cruz del Sur.

Greetngs,
After our storms this Winter, especially the big one in early December,
the Eastern beverage got busted up and it took me several weeks to
finally get it back up. It was too cold and wet to solder the splices so
I just twisted the splices and taped then up for the time being. I got
out yesterday and soldered two splices, as we were up into the 50s F, so
my little butane soldering pencil worked okey, but there was a wind, so
keeping it lit was not always easy. I was thinking of buying another 250
feet of outdoor extention cord to give me 500 feet total. With that, I
would have enough to reach the other splices that aren't soldered on the
beverage. I have a Radio Shack soldering gun (100/140 watts). Would the
soldering gun work running it through that much extention cord? If so,
would it harm the transformer in the gun? I fiqure a A/C soldering
pencil would not be harmed as there is no tranformer, but I don't have
A/C soldering pencil that has much wattage. The gun would work better.
With a pencil, if the voltage dropped too low the pencil would not get
hot enough, but with the transforer in the gun, I have no clue. Does
anyone know? If running 500 feet of extention cord would work, I will go
buy another 250 feet. I have run the soldering gun through 200 feet of
cord and that worked ok. I also have a deep cycle 12V battery I could
use with an 120v inverter, but thing weighs 70 pounds and not that easy
to carry. Any help would be appreciated.
Thanks.

Patrick,
If you need to solder wire in cold weather, use a propane torch. A torch is
best suited to uninsulated stranded copper wire, as the heat will cause the
insulation on typical "zip cord" extension wire to melt back on either side
of the spice - but it will deliver enough heat to make a perfect solder
joint in just seconds - even if the ambient temps are quite cold. Use rather
heavy gauge rosin-core solder, and set the flame as low as possible. It's
best to do it when the winds are calm.
I constructed a 300-foot horizontal loop that had six spices - all of which
were soldered in this fashion. It has held up perfectly through 4
northeastern winters.

Dear amigo:
After running many tests... we found out what may best be described as
an almost
optimum setting of the audio frequency response curve that will provide my
listeners with the best possible audio ?punch?, that is audio that will
get trough
interference of all kinds...
As a bonus, if you remove the lower frequency segment of the audio ,
that is from
30 to 250 Hertz, your transmitter won?t waste power modulating that segment
of the audio spectrum that provides, according to psychologists and
audiologists,
practically no useful information for the human to decode voice.
Although of less significance, it is also a good idea to introduce a
high frequency
cut with a 12 or 18 dB per octave slope after 2.7 kilohertz or so...
I have heard my shows on short wave under the most difficult reception
conditions
and the programs came in a lot better than the other shows recorded with
the ?standard?studio quality.
I am sure that you are aware that the typical short wave broadcast
transmitter?s
audio frequency response curve starts around 50 Hertz and ends quite
abruptly
at around 4.5 kiloHertz with a very steep slope that is required in
order to comply
with the channel separation requirements...
The studio microphones, audio mixers, master control program amplifiers,
fiber optic
coders and decoders, STLs etc. are alway easily capable of handling a
minimum
bandwidth of between 20 and 15,000 Hertz... while the short wave transmitter
by its own nature is only cable of responding from about 50 to 4500
Hertz... and
if you really want to be heard under the most difficult reception
conditions, your
voice modulation should be restricted to the range between 250 and 3000
Hertz or
so...

Dear amigo Bob Chandler VE3SRE has hit the bullseye right in the middle !!!
After several years of doing Dxers Unlimited, one day the former station
chief
engineer and now senior technical advisor Luis Pruna Amer I.E. and
your?s truly
were talking about the people who listened to my show... Then we ask for
help
from the station?s correspondence department, and Irma Armas the head of the
English section came out with the surprising result that Dxers Unlimited
had been
heard and reported from 162 ?DX entitities?of the 192 that have been
reported
to Radio Habana Cuba until that time ( this happened about 5 years ago
or so )
Then Pruna and yours truly agreed to optimize the audio frequency
response curve
for not only voice, but specifically to provide optimum response to my
voice.
We ran many tests using an audio frequency spectrum analyzer , and ended
up with
a pretty nice audio that really punches trough ... The curve cuts down fast
below 250 Hertz, and provides a boost of about 6 dB between 500 and 1500
Hertz
then it is again flat up to 2500 Hertz and from there it goes down with
a very steep
descent of 12 dB per octave at first and then 18 dB per octave later.
THIS IS NOT HI-FI !!! But as Bob Chandler has very well analyzed and brought
to our attention, that type of audio frequency curve shaping ( together
with the use
of a well designed and adjusted audio compressor ) will increase the
possibility of
reception of the program in areas where the signal to noise ratio is not of
the typical broadcast quality ( no less than 26 dB signal to noise ratio
minimm ).
I remember when we used the old Siemens and RFT transmitters for
broadcasting
Radio Havana Cuba on single side band, that the 10 kiloWatts PEP Siemens
provided the coverage of a 100 kiloWatt AM transmitter !!!.
So, although Dxers Unlimited doesn?t make use of the full potential
quality of the
station?s studios. STL?s , fiber optic links and transmitters... I do
intend to keep
using the ?special for Arnie?s voice?frequency response curve !!!
