First: thanks to VE3NH VK2IC K2HN K7TJR ON4KJ DL2MDZ AC7A AC7A W7IUV KB8NNU
SM2LIY N3CO N3OX KK7UV KU0A SM6CPY WA5POK N2WN who kindly answered my
questions.
Then let me tell a little story: this evening during a pizza dinner a
friend has said to me: "I have read that you are searching for 2N5109, i
have a dozen in my scrapbox"
I discovered that he was working around the same project! He also asked:
please find the way to obtain a variable gain of the preamplifier.
In fact a variable gain is a desirable feature, maybe in certain conditions
reducing the gain can be a good choice?
Thanks again, and good luck in the pile-up!
