    Worked on this a couple of years ago and it never made the final tests successfully. I suspect that I static zapped a BF 988 mosfet which is the first if amp. How does one test one of those? Properly?

    I have a couple of low power rf signal sources that may be used for signal input such as the MFJ-269C but would have to rig up an attenuator of sorts and even then not sure the scope would even see it.

    I am open to all reasonable suggestions...
