This is a good example, don't do what you just thought about doing - you will ruin the rx radio set. Before you transmit into the cavity filter be sure it has some isolation to the rx port, this is a must... Now how can you test this? Try a little extra isolation - don't connect direct, huh? what

Doug, your concerns about the line voltage is a valid one however the ferro-resonant type supplies can generally overcome 10-15 percent fluctuation in line voltage. I like your grounding questions and using a split bolt to add your 6awg stranded wire to the existing ground bus is going to be as

I doubt if you would get repeater council approval to link at that power level, most linking is done 15-20 miles with 3-5 watts and then someone might turn it up to 10 watts to overcome foliage and insure a reliable path in horrible weather. dy3lmk143_13mhz wrote: I've never had experience on

If what you are trying to get is a stronger signal from a weaker one, use an open npn collector as the switch - in order for it to trigger with reliability you do need for the signal to go above 3 and below 2 volts for this to occur - it takes the strain off the radio electronics and you can also

Well, I am thinking that using an op-amp circuit might help you out on the audio line out with a .3-.5 blocking cap in series with a 50k pot. Op-amps demand very little current to activate, and can be reliable in rf fields by sprinkling some 0.1 tantalum caps around where there is dc bus voltages
