Hi Gonz,
Sorry, I don't speak Spanish, but doing my best with Google Translate.
Greetings, long aerial and hear the band a few days ago got an FM station in one of the frequency, the station is not new and has never happened, but suddenly began to hear, I placed a filter ABF AIR BAND -128 and does nothing, the sound of continuous FM radio station, I have to wait a few days doctor to see if one is removed, but I can not think of this.
Interesting that the interference just appeared all of a sudden, did your antenna move? Also check those connections on the feed line! That filter doesn't look like it provides much rejection in the FM band, the PAR VHF-FM has pretty good attenuation in the FM band and could be combined with the AOR filter. It would be quite bulky if using on a hand held.
Es interesante que la interferencia acaba de aparecer, de repente, se movió tu antena? También puedes ver las conexiones en la línea de alimentación! Este filtro no parece que proporciona un rechazo tanto en la banda de FM, el PAR VHF-FM tiene una atenuación muy bien en la banda de FM y puede combinarse con el filtro de AOR. Sería muy voluminoso si se usan en una mano.
