Default You can write to him to ask details, please use simple English or Spanish.

He is learning English, and Spanish is his native language.

Inside forum, if something is written in Spanish, must have English version also.

Carlos

Default Because International language is English.

So, people is prepared to face English, and not prepared to other languages.

This way, using other language, the comunication will be not open to all forum people anymore...i think it is against rules, if not written those rules, we can agreed that this is fair.

I am explaining that, because already made the mistake, and was informed that this is not kind...so...i learned that.

regards,

Carlos

Default You are welcome Rodolfo, if you can, post your personal adress to direct contact here

Because the forum mail system may be monitored (not sure) and that sittuation create the need to use English.... to allow monitoring, as it is the forum mailing, they have responsabilities and have to watch if no fight is happening using their system.

This way, if you post you personnal mail adress, to direct mailing to you, people can use Spanish, Portunhol (my spanish...hehe).

"Rodolfo, si puedes, ponga tu personal mail direccion en esto forum, ya que la communicaccion que hacemos uso, a mi parece, que debe ser monitorada, hace que ellos, los mantenedores, necessitan saber se el sistema de communicaccion del forum no está siendo utilizado para guerrilhas e ataques personales.... esto hace que utilicemos la lengua oficial, el Ingles......no entanto, la directa direccion le permite la conversaccion en otra lengua"

regards, saludos,

Carlos Eugênio Mergulhão

so what is this for? single ended to balenced output? RI, RI1, RI2, and RF seem small. a biasing resistor is in place for U1, but not U2. are U3 and U4 needed?
