    The College in my town has opened a nice studio...good space, but, we are having a problem...the college have a Radio Station too(with the respective humoungous antenna)...the studio contractor aparently forgot to add the Faraday cage in the studio...so, the radio is coming to my equipments...and hearing in the headphones...what can i do to eliminate or minimize the radio effect in the studio? what alternative you have to the faraday stuff? is it posibble to do something outside of the building? :roll:

    Can you give a bit more information?

    How large is the transmitter?

    Is it an AM or FM station?

    Are you picking this up on EVERYTHING or only on Microphone and phono inputs?

    Where physically are you located in relationship to the antenna?

    There are lots of ways to deal with this just need to know some specifics and the more you can supply the better.

    well...it´s really close from the antena...about...100 mts...(we are in a third floor, the last one) it´s a FM station with enough power to cover all the city...a big city...mmmm...i think, we are picking in everything, cause, can hear in the headphones...the console, wires...i´m not very sure...what do you think? do you need some exactly info?....ah, i forgot, the high of the antena its about 120 mts....thanks....

    Ok the first thing is to make sure where the RF is entering your equipment. Most times FM will not come though walls and get into equipment like AM will. I don't know how technically adept you are so it is hard to know what I can tell you to try.

    All you need to decode AM is a simple diode which could be a bad solder joint or a bum connection. Since decoding FM is much more difficult I am wondering how it is getting into you equipment. It maybe that the RF is simply overwhelming the audio in your console but if the console is grounded and it is made of metal that would seem impropable. If you could provide some more detailed information I would appreciate it and it would make the job easier. Thanks.

    Is there any chance the college radio station engineer(If they have a qualified engineer.) would help you? Otherwise, unless its' a quick-fix(One "bad" piece of equipment in your studio that you happen to find by unplugging it.), this could be nearly impossible to correct without alot of knowledge... Of course, it's possible IT IS the radio station doing something "wrong" themselves - which they may or may not want to correct? May not hurt to ask - kindly, sweetly, humbly, non-threateningly?(And, their help may not cost you anything...)

    Another option would be to hire an RF(Radio) engineer of your own to "consult" on the problem. A good local radio station engineer(If his station sounds good..?), again, may be your best bet and may even be quite affordable.
