Nandu, why not just leave the new instrument and the commercial RF
ammeter connected in series, and then adjust the power level (by detuning) of the power source (transmitter) and make a calibration table by comparing known current to that which you are reading on dial of new instrument? Some of us "old school" would make a new instrument dial by disassembling the instrument, and reversing the dial plate (flipping it over). or creating a new paper dial plate with a computer, and glueing it over the old one. Good luck, Lynn, W7LTQ since December 1948 |

Many thanks for your suggestions. Yes, I should do it one of these days. The existing dial is well suited for marking with a fine 'permanent marker' pen. 73 Nandu. |
