Can anyone tell me the mod to allow 10/11 meter operation on a Dentron Clipperton L?

Every Clipperton I have seen already had the "15" band jumped for 10/11 on the output coil. Sure wish I had taken a picture, or made a note of how many turns down the coil to go. The input is untuned. I do have a note here that a 0.3 uH coil in parallel with a 250 pf trimmer cap will improve the input match for 11/10 meters, placed between the center wire of the input coax from the relay and ground (parallel to the input circuit). The trimmer cap is tuned for best input match with a SWR meter BETWEEN the amp and radio.

Sure wish I could remember how many turns from the end of the output coil will tune 11/10. Oops.

I use a alligator clip and slip it down the coil till I get what and then jump it in that area. But watch what your doing that 450 volts will get you. Can't tell you how many times I've been hit worst time was in 89 took two days and a external pacemaker to get me back in tune. Glad I was only 23 yrs old.
