I'm looking at meters: triple window meters that show mod/swr and RF at the same time. If a meter goes bad, like the modulation meter, is the repair generally popping out the old 2.5' one and installing the new? Or is it a problem somewhere in the guts of the thing. Can the majority of meter failures be repaired in this way? |

The meter itself seldom goes,usually a resistor poofs in the guts,these units are factory calibrated and just changing out the component won't do,you need a set that produces known values to recalibrate,unfortunately it is simpler,easier and cheaper to buy a whole new unit.I know most of us on here are not made of money,so I know you probably didn't want to hear this,sorry,but I hope this helped. |

Well, I had a little movile allan meter which was rated for 10w.
I put 400 in it and its wasted. |

That's funny Taz
What were you expecting to see when you blew 400 into it? And how long did it take for the needle to go from zero to 10?

Taz,try this;get a 250volt dc p.s. a 25volt,1000mfd cap,100 feet of twin lead.Attach one end of twin lead to p.s.,other end to cap in correct polarity,string out wire plug in p.s. and turn it on,BAM,that is if you like to blow up things. |

It was by accident. It went so fast it broke the needle. |

Hehe, that's a "blown" meter for sure but sounds like a 10w meter isn't too hard to replace. A problem in the guts of it eh Bigbob? Hmm, Murphy's Law it seems, "a simple solution is never a solution". |
