    Need help with a DMM

    :)if all else fails get another multimeter and remember anything higher than 1000 volts you would need a high voltage resister devider to help and with your multimeter you can measure these high voltages if any voltage you measure exceeds the maximin voltage rateing of your multimeter then...

    big ear, fm transmitter.

    :)thankyou ante and audio guru at the moment i have a 47k load resister and 10k pot still in it and if i press down on the pot the sensitivity jumps a little so i want to increase it more let me geuss if i change the pot to 25k and decrease the resister to 10k will that do it, the dish is only small

    big ear, fm transmitter.

    :)ante was that a few beers or few cartons of beer , i took it into concideration, that some of the bug transmitters use a 47k load resister for the electret mic so i tried it and got more sensitivity even though i want to get as much as i can so much that i could hear a flea circus on a passing...

    seeking parabolic mic circuit

    audio guru, your a real genious, i changed the 2.2k load resister to a 10 k and it increased the sensitivity well, is that the maximin sensitivity i can get, if the sensitivity can be increased to maximin, then what load resister do you recamend i use. i may be able to switch in various...

    seeking parabolic mic circuit

    :)audio guru ive allready added the 10uf electro between pins 1 and 8 incase you dident notice in the latest pictures, just slide the picture to the left and youll see, ive been checking out the microphone sections of other bug transmitters and some load resisters vary in values. anyhow thanks...
