Somebody is lying. I just got my Astatic 600 SWR/PWR/MOD meter. Hooked it up to my radio with 3 feet of Mini 8 cable. And my SWRs are really HIGH! When I used the internal meter of the radio my SWRs are low. So who is lying? The radio is a RCI 2985DX. Antenna is a Shakespear Super Big Stick. |

Im'a rookie to this game but what came to my mind mind is maybe the calibration on the meter is high and the calibration on the radio is right. Could it be that easy? If not, at least I gave you all something to laugh at!! Metro 446 |

Hard to tell. Could be a bad jumper if the swr is only high when you have it hooked up. Have you tryed a different radio/meter too? I would ask a buddy to try their meter or radio meter to make sure. Are you running power? Putting the meter after the amp will read higher swrs too. |

Nope, not running power. I was planning on getting an amp but I'm going to hold off until I solve the SWR problems. I used two different jumpers. Both 3 foot cables. One was a 3 foot Mini 8 jumper that I bought from Copper. The other one is a 3 foot jumper (belden cable) I got from ebay. As for using another meter. I'm going to have to find another meter to use. The readings I get from the radio and the SWR meter are way off. The radio would say 1.2:1 or 1.1:1 and the Astatic meter would say 2.5:1, or 3:1. I know I'm getting out. So it really confuses me. I mainly talk on SSB so the higher SWR doesn't hurt my radio so much. But I definately need to find out whats wrong. |

I have the same kind of problem. I go more by the radio. The swr on my groundless wilson is like 3:1 or higher. I don't talk on it much so I don't worry. I use it for testing mainly since I don't have a dummy load yet. What kind of radio do you have? Does the radio say that the swr is that high when you have the meter/jumper in line? |

I'm running a RCI 2985DX. The radio's SWR meter reads around 1.1-1.3 from 26mhz-29mhz. I've tested the jumper by using a barrel connector and connecting it to my antenna coax. I don't get high SWRs when I do that. So I think the jumper is fine. |

Don't know for sure, but sounds like it might just be the meter. Maybe someone else has some ideas. I would just try another meter. |

I have a pdc 700 which is the same as the astatic and I'm having swr problems as well. Only thing my meter says the swr is perfect, and another meter says its way off. So your not alone with this problem. I too am trying to find out which is right. Look under tech. question and find my post named "believe it or not" and read what my problems are. I have yet to get an answer. |

814 : See if your local CB tech will let you borrow a meter that is known to be good and recheck your system.I never have relied on a radio swr reading meter.The only reason I want a meter on a radio is for some relative receive signal strength.I have used Dosy for years with only a few problems.I also use the new MFJ 259B which checks SWR and coax ohms at the same time without the radio even being connected.Also you can hook up a different antenna and recheck to see if the antenna is malfunctioning.73's |
