Re: "active antenna preamplifiers" in ham radio May 1986

Hi Fred,
?
Thanks for the advice.
?
I had gotten a Soviet KP901B about 20 years ago.
I remembered it and tried to improvise.
?
The radiater is a Jpanese brass coin with a hole.
Indeed, it worked as an Antenna.
The noise level seems to be a little high, almost same as 2N7002.
However, it seems acceptable because of the high noise level in my QTH.
IMD felt it was good.
to make it better, need more acceptance of receiver.
tnx & 73, Hisami 7L4IOU
