Hola,
llevamos mas de un año emitiendo con una emisora Cyber MAX FM de 300w. Estamos en el sur de España y desde hace unas semanas las temperaturas se han disparado, llegando a los 40 grados, y la ubicación de la emisora no es precisamente la mas fresca. Hemos refrigerado la habitación, pero aún así los sensores de la emisora estan dando medidas muy altas. No hemos podido encontrar la temperatura máxima recomendada para esta emisora. Actualmente la alarma de temperatura esta a 70º. Hemos bajado la potencia de emisión y la temperatura de emisión se mantiene en unos 50-55 º, pero la temperatura del excitador se dispara a los 65º llegando a los 70º en algunos momentos.
Cuando alarma salta apaga la emisora y la vuelve encender en cuanto baja de los 70º, esto ocurre muy rapido y la emisora no para de encenderse y apagarse. ¿Puede perjudicar esto a la emisora?
La pregunta es, ¿ cual sería la temperatura máxima recomendada para no perjudicar a la emisora? Gracias anticipadas, un saludo.

Hello,
took over a year with a radio broadcast Cyber ​​MAX FM 300W. We are in southern Spain and a few weeks the temperatures have soared, reaching 40 degrees, and the location of the station is not exactly the freshest. We cooled the room, yet the station sensors are providing very high action. We could not find the recommended maximum temperature for this station. Currently the temperature alarm is 70 º. We have lowered the output power and emission temperature is maintained at about 50-55 degrees, but the temperature of the driver is fired at 65 ° reaching 70 degrees at times.
When buzzer goes off the station and turn back low as 70 degrees, this happens very fast and the station not to turn on and off. Can this harm to the station?
The question is, what would be the maximum recommended to avoid prejudicing the station? Thanks in advance, greetings.

Air conditioning is recommended, 40C is high temperature for transmitter room.
That is why there is always air conditioning in transmitter rooms and also cell phone companies use it in their equipment rooms.
Or at least reduce the power until this heat wave passes.
To avoid alarm you can also increase alarm temperature to 80C, it will probably be ok, but its life may be shortened a little bit.

yes,air con is a must in all transmitter rooms,no matter what,if you cant afford air con and you cant afford too lower the power of transmitter there is a suggestion i can give you..
you will need lengths of PVC pipe,6inch or 3 inch,heavy duty air blower (like a bouncy castle one) and very fine mesh,2 metres,cement
1. knock out a hole in the external wall too fit the diametre of the pipe.
2. fit pipe into the hole and cut mesh wire too fit pipe and fix it too pipe and cement pipe in place.
3.run the pipe too the blower intake fan,normelly too the side of unit. You can buy a pipe reducer or gainer too go from your pipe too blower.make good seal too it.again,you could use mesh wire here too too prevent debis entering it
4.do the same on the blower output part,mesh again and good seal into pipe,and run this too the transmitter and get mesh and put it on the end of the pipe,end of the pipe shud be at least 2-3 feet from transmitters fan air.(NO CLOSER OR YOU MAY BURN OUT THE TRANSMITTER FAN)
I have done this before and it reduce'd the temp of the transmitter considerably.
all should cost you about 100 euro maybe less for this set up,let us know how you get on

Abre el transmisor y limpia de polvo los ventiladores con una aspiradora. Comprueba después que los ventiladores funcionan bien. Si es posible conecta al transmisor otro ventilador interno. Los transmisores suelen estar en casetas aisladas en el campo y casi nunca tienen aire acondicionado. Deben de estar preparados para las altas temperaturas sin usar aire acondicionado. Si un transmisor no soporta el calor del Sur de España, es que tiene algún problema o no está bien diseñado para disipar el calor. Si no quieres complicarte mucho, pon un ventilador externo muy cerca del transmisor. Eso ayudará a disipar mejor el calor.
Gracías por la respuesta. Hemos instalado algunos extractores de aire en la habitación para que circule el aire y ha bajado la temperatura. Asi que aguantaremos lo que queda de verano.
