Hans, what practical use you see in having a JFET XTAL oscillator for three frequencies when there is a very sensitive balance needed to achieve that? OK, beside the pure satisfaction when it works.?
None. The pure satisfaction that it works is enough for me. On this and on most of the rest of what I do. Practical use is a bonus side-effect.?
Besides, it is not my work, it is Kostas SV3ORA, I am just an interested follower of his work.?
Or, as our dearly beloved departed friend George Dobbs G3RJV (SK, RIP) was known to have said (I quote from? )
George once explained ¡°why
QRP¡±, he said: ¡°Because it is a
hobby we don¡¯t have to do it - or
mean anything - or fit into the
world plan. As long as you can
do one useless thing a day - life
still has some meaning and that
is the essence and the joy of
life¡±.
If you look around the other articles at? you will, if you?are like me (and George), find much of interest!
