If I have a loop circuit unconnected to a transmitter
could it not oscillate under ideal conditions?

Art, what is the power source?

Wow, this brought forth a lot of comments to contemplate.

Regarding your question. I was thinking of energy radiated
by a nearby source such as another radiator with very loose
coupling from which it gets energy, and current flows in the loop,
I then reason that with energy being applied to the loop it will also
create oscillation PLUS a emf feedback to the initiating energy
scource
which then also reacts giving a 'pulse' to continue oscillation as
well as energy for radiation. I see the loop not only reradiating the
initial frequency impinged upon it by the outside source but also a
radiation at the frequency of oscillation somewhat similar to that
seen in a receiver where the object is to bring the two frequencies
together. Now I am not electrically based and I am also guilty of
using wrong terms in my description but I am using the hobby
to experiment and learn. Now I did play with such a set up and was
able to see two frequencies on the 141T, Whether I interpreted
correctly what I saw is another matter. Fortunately I am not teaching
the subject or trying to make a living from it nor do I have a resume
to protect which gives me the opportunity to speculate, play around
with the hobby without the danger of being beheaded.
That is what is great about this hobby, it accepts all, the curious
and the appliance operators all of which are not frightened by showing
their ignorance of the subject but trying just the same. If I thought
I knew a bit about conjugate matches I would have participated in the
other postings but that was really beyond my ken and interest so you
lucked out there.
