Hi Ben,
Only if you had a lot of spare time. The common
Grid Dip Oscillator tends to be relatively broad
banded compared to more modern tools like the
MFJ-259 and a Service Monitor. Other issues like
the frequency drift need to be kept under control.
Loop coupling is fine, you just have to make
sure you're past the min critical loop length
to keep the coupling issues out of the main
picture. So a 3 inch hairpin style loop or
two/three turns of wire around a 1/2, 3/4 or
1 inch form will probably work. Lead length
is not an issue as long as you keep things
smart.
good luck
