pro 5100 tx problem

Post by Enrique Torres »

Hello everyone I have a pro5100 vhf radio, the problem is that sometimes it transmits well and some times it does not transmit at all, this radio does not display a power bar when it transmits.
So the only way that I know when the radio is transmiting well is using a power - swr meter, another fact that I note is when the radio transmits it makes a nosie on the receiving party ( like the power supply is not enough for the tx power ( I am using a 20 amps, 12 volts power supply for 50 watts on the radio) or noise like the antenna is not well tuned.
Does this mean that the radio output transistor is near to blow or how do I solve this problem?. I use cps 6.01 La or Az to write this radio, the antenna is well tuned ( 1.5:1 (swr)).
Another question is how do I make squelch gets less tight so I can hear a long distance transmissions.
Thanks for reading any help will be great.

Hi men...

1... On the Squelch, must fit it with the Global Tuner that comes with the CPS and must be in the band and frequency that you use.

2... On the lost one of power (watts), it seems to be a problem of source of power supply, please..., aside from placing power-meter (wattmeter) to him, places to tester (multimeter) in the entrance of voltage for to measure constan voltage and the amperage. make with patience.

Bye...

Amigo, como estas?

Te saludo desde Caracas-Venezuela..

Oye, ese problema que tu tienes parece ser un problema de fuente de poder, checa (como dicen ustedes) la entrada de voltage y el consumo en amperes cuando el equipo trasmite...si el radio no se ha golpeado (caido), esta debe de ser la falla: fuente de poder de mala calidad o tambien puede ser que el conector de antena (mini-uhf) este mal hecho o partido y por esta razon el equipo entra en modo de proteccion para no dañarse.

Sobre lo del squelch sensible, debes esto ajustarlo con el Global Tuner que trajo el programa. entras en la pantalla de leer el equipo, luego el te va ha mostrar varias sub-bandas (frecuencias) y las medidas (valores) de fabrica. esto lo deberias de ajustar con un monitor de servicio, pero si no lo tienes, baja la medida que esta mas cerca de tus frecuencias de operacion hasta que se habra el squelch (audio) y luego lo subes dos unidades para que no se este disparando a cada momento.

Espero te haya podido ayudar...

Saludos

Mauro

Thanks for answering, I will try what your advise .
Gracias compañero efectívamente no tengo monitor de servicio pero voy a intentar lo del tunner, no sabía que estos rádios tuvieran una autoprotección de salida en caso de falla ( cable roto, antena mal ajustada, etc.)
Saludos.
