Been off air for 32 years. Just bought Titan DX and TS590S Assembled, checked everything 5-6 times, and fired up new set up Noticed little signal on all bands. Strongest was S3 590 tuner beeps warning SWR over 10, everywhere Could a shorted Pl259 cause the lack of reception as well as SWR issue? Again, I've been silent for 32 years and tonight was to be my homecoming!!!! Thanks in advance |

A shorted PL259 certainly could cause a 10:1 SWR. A continuity check between the center conductor and the shield would be the place to start. Bill |

A short circuit or an open circuit would cause extreme SWR. Check and re-seat your connectors, make sure they're tight. Make sure your coax is good. Check that the antenna is properly assembled. Good luck & 73 - Martin - AA6E |

It was shorted. Haven't fixed yet(tonight will do), but would that also explain very low reception on all HF bands? Thanks |

Yes, a short normally results in poor reception on all HF bands. Normally, the short is right at the coax connector. You may be able to determine which side the short is on with an ohmmeter--you will get a lower reading on the side closest to the short--by a few tenths of an ohm for 100 ft of low loss cable. Even better would be an antenna analyzer, which will show a dramatic difference between measurements of either side. Zack Lau W1VT ARRL Senior Lab Engineer |
