Help with Kenwood 830...
 
I don't know if this rig qualifies as a boatanchor, but I thought I would
ask as there are many here who are knowledgable.
I got the rig from a freind.
The 40 meter rf pot has a problem. The ferret core is bottomed out and won't
screw back (upward) or catch the threads/coil.
Is there a tip or trick to 'grab' the ferret core to get it to catch.?
I'd hate to have to tear the board out or send it out for service.
Any suggestions appreciated. Josh

I have been known to smack the core to break it into pieces as it will
fracture fairly easy. Then flip it over and the pieces fall out. Or how
about a little bit of epoxy on the end of a tooth pick. Let it dry and then
unscrew it. Of course, you need to make sure you don't glue the slug onto
the form. Can you drill a home through the board to allow it to pass out
the bottom? You might be able to shine a bright light through from the
bottom of the board to see if you would disturb any traces. Just some
ideas..

I would find a slug of the same size and screw it in from top of
coil,the slug that is bottomed out is not of any use ,just leave it
there and tune with the new slug.. Harold W4PQW

Remove the coil and unscrew it from the bottom. Turn the core over and put
it back in upside down. It has an adjustment notch on each end.

As to removing it. You don't need to remove the board. There is a trap door
under it. Remove the AF unit and you will see it.

It could already be cracked. Leaving the old one in there sounds like a
good & easy idea, but if it can move around, it could later detune it.

I wouldn't call it a "pot". That sounds strange. I don't know just what
this slug-tuned-coil looks like, but have an 830s.
