i got 2 swr meters one is a dody test center4002 and the other is a pdc 700..ithink anyways they both read different swrs doesnt matter if its my base or moblie.the dosy always reads higher in the moblie the dosy reads a1.5swr on ch.20. the pdc reads about a 1.1 or 1.2 if readings vary with different meters then what ones right can they be calibrated if so what one also the dosy on the modulation side doesnt seem too move needle too calibrate it |

the BEST way to test a swr meter is put a 50 ohm dummy load on the output ( ant side ) cal to full scale go to SWR and if it reads low say 1.2 / 1 or less its working. |

the dosy doesnt have any numbers between 1and 1.5 but im guessing it showed a 1.2 or 1.3 cause it wasbetween a 1 and 1.5 how that sound bruce |

anything under 1.3 to 1 is less than 4 % back ... not enough to worry about. |
