I have a vhf band voice-repeater station that located at near-top mountain (approx. 9000 feet above sea level). And many repeater station, vhf-uhf, located at there too. I got a problem that I can't solve. The input signal always annoyed by interference noise signal. Although I have put two own-made Bandpass Cavity filter before rx unit. I use Hustler G5-150 and, I don't know the brand of RX unit, but some people says that is Intron, taxi radio. That type T-530. I use tone encoder too. 10D-FB as the cable. Can anyone help me? Yahoo!
