Hello Pat,

I use Opera for a browser (www.opera.com) and it has a great ZOOM button.

I can see the pictures beautifully and zoom in to see the cap value is:

.01 MFD 2500 WVDC

Hi Doc,

Looks like a relatively high uH coil, probably way in excess of needed
inductance for a 160 m project..
Looks like a capacitor across it, that I cannot read the value of, but could
be used as a resonating cap and along with a dip meter, or MFJ analyzer
could be used to determine the resonant freq, and back calculate the coil
inductance.  Kinda thin wire, too, for use as  a power coil around 160.
The bottom photo must have some sort of aliasing, kinda a moire pattern that
obscures the actual shape and number of turns...

73, DX, de Pat Barthelow AA6EG aa6eg@hotmail.com

The coil looks very much like the plate chokes we used to have in our RF
induction heating generators.
Depending on the frequency of the system we had some that were up to three
feet long and six to eight inches in diameter.
