Hi everybody,
Last time I used the transmitter the s-meter was not working when tried to check SWR or transmit power (does with received RF), neither works the CAL pot. Today I've checked the final transistors and one of them looked as shorted (Emisor-Base conection marked as 022 on my multimeter). Also checked the diode of the transistor and had the same mesure inverted and also direct polarization, so I thought it was a short. After change both I checked again and...got the same mesures (haven't checked the smeter yet 'cause only have mobile setup).
So...
Anyone knows...
a) Why is happening this? Is normal?
b) What is going on with the s-meter?
Any idea is wellcome
PD: I have no external SWR or power meter...
Thanks for your support.
