There's interference problems every where
High power considering, that with one exception, Cuba was not authorized to operate at the powers they were using, and for all I know, some of the frequencies they occupied.DavidEduardo said:Icangelp said:I might add, Cubans are still driving the very same automobiles they bought in the early 1960's, a time when they were filling almost every frequency with Soviet gifted high powered transmitters.
The Czech transmitters were not numerous nor particularly high powered. There was one 300 kw unit, a couple of 120 kw ones, and a half dozen or so 30 kw transmitters out of over 100 AMs in the country.
Those Czech units were not very reliable in the long run, and when the USSR dissolved, the tubes and parts became scarce. Most were modified and are seemingly not running high power.
As to AMs moving to FM, in fact AMs added FM in places like Colombia and Venezuela and the Dominican Republic as well as Central America. While many of the Caribbean islands have reduced AM transmissions and added loads of FMs, such as seen in Jamaica, those were never the auroral / sunspot related invaders that Cuba, Venezuela and Colombia were. And none of those countries has reduced the AM station count... if anything, it has increased.... and there are higer power stations now.

I would argue that for a country with little or no revenue generating activity, at least in the 1960's, Cuba was unusually well served.
The 1966 WRTH lists 570 @10KW, 590 @25/15KW, 630 @50KW, 640 @50KW, 690 @50KW, 720 @30KW, 730 @10KW, 740 @10KW, 760 @10KW, 790 @10KW, 830 @10KW, 910 @10KW.
After checking things out, I agree that AM is alive & well in Central and South America, ...
It seems like yesterday I logged the rare in the midwest, Radio Swan on 1160. What ever happened to the Gibralter Steamship Company? Bought by Princess Cruise Lines? Filed Chapter 7 and faded away?![]()
gar fla said:Swfl. I'm wondering since you're more south than I am, what do you hear on 740 at night?
I'm figuring you don't hear WYGM as strong as I do up here and maybe have a better chance to hear other stations mixed with KTRH.
I ask because I mentioned in the other thread about listening for KCBS and being you are more south, more of their signal should go that way.
Cuba may have had commodities to sell, but I wonder if the economy was equivalent to a comparable sized U.S. state, especially since the wealth was in very few hands, and then after Castro took over, in government hands.DavidEduardo said:Icangelp said:High power considering, that with one exception, Cuba was not authorized to operate at the powers they were using, and for all I know, some of the frequencies they occupied.
Early on in the Castro government, the NARBA treaty was abrogated. Cuba did not, after (albeit unilaterally) abrogation, have to respect the allocation system of North America. As is true with every country south of Mexico and most of the nations of the Caribbean, Cuba did not particularly care about interfering with AM stations elsewhere. In a sense, no different that Guatemala putting 10 kw stations on US clears like 720, 700 and 1020.

Cuba had considerable economic strength in the 60's, but Fidel's government kind of destroyed that. First, they were a major sugar exporter in a time when that commodity had a high price: They also exported byproducts made of bagaso, the fiber from the cane. And they had nickel reserves, fishing, etc.
Cuba had been crushed by NARBA, and given few decent regional frequencies. Considering the island is nearly 800 miles long, it needed many more 1-B clears and lot's more regionals... but all the earlier southern regionals in the US put their night patterns towards Cuba, making operation less than viable.

Many single US markets have comparable facilities. Cuba is the equivalent of a big US state, not a single city.

I just mentioned Colombia and Venezuela, where AM is quite alive. In most of Central America, AM is dead or near death, with station counts way off, and almost all listening on FM. El Salvador has about half the AMs it once had, and half of those are evangelical religious stations. Ecuador is losing AMs at the rate of a couple a month, with less than half still on the air. Chile has seen big 100 kw AMs like Minería turn in the AM license as "unviable." Jamaica has turned off all AMs, and Mexico is turning off about 75% of all AMs.

That was a dummy corporation, bought with CIA money and run out of the offices of AIR, the Asociacion Interamericana de Radiodifusion in downtown Miami a half block south of Flagler on, if I recall, 2nd or 3rd; Ramón Goicochea, the secretary general of AIR was also an official of Swan / Americas.
Schroedingers Cat said:I can remember back in the early 1970s nulling out WMAQ in the O'Hare/NW Chicago area and hearing absolutely no interference. A few years later, it sounded no less interfered with than a III-A and the interfering signal was in Spanish, and I assumed, Cuban. I remember that the Cuban station on 720 was at least 20 Hz off frequency and gave a loud heterodyne hum in Michigan at times on WGN.
Icangelp said:Cuba certainly would not have had those transmitters if it weren't for the Soviet Union and its satelites.
I remember Radio Swan/Radio Americas well, and in the '70s I had a neighbor whose father was involved in the technical side of that endeavor.
Not Cuban, but on the U.S. government side of things as I recall. My wife & I moved out of the neighborhood shortly after he moved in. Never got a chance to grill him on the subject.DavidEduardo said:Icangelp said:Cuba certainly would not have had those transmitters if it weren't for the Soviet Union and its satelites.
Most of the higher powered transmitters were installed by the big Cuban networks, particularly Circuito CMQ (the ones from 630 up to around 700) but many were directional per NARBA. The revolutionary government did away with the directionals.
In Latin America, where literacy was quite low in that era, and TV had not penetrated to any extent, AM radio was the leading advertising medium. Colombia, for example, had dozens of 50 kw AMs by the early 60's and hundreds of 10 to 20 kw stations. Much of the importance of radio involved the poor mail and telephone communication in rural areas, too.

Cuban, by any chance? I never saw anyone at Radio Americas who wasn't, including on a merry little plane flight out of Opa Loka to Isla de Cisne. The whole thing had obvious US government money, and was manned by the more militant refugees. For quite a few years, i had a tape of the broadcasts on the evening of the Bay of Pigs invasion, exhorting the Cuban masses to rise up and rebel. Those that rose up were killed or sent to Combinado del Este or Isla de Pinos.
