[Kenwood] SM 230 scope trace question.

Tue Apr 13 20:04:59 EDT 2010

Alan,
On my SM-230, the knob labeled INTENSITY just to the right of the power
button has a 2nd function. If you pull it out, it rotates the trace.
Good luck!
Troy, AD5RG

Looking for info on making the trace parallel to the horiz. grid lines.
Opened the unit up, expecting to find the usual coil of copper wire on the
neck of the CRT, but no. Undid the rear saddle clamp and rotated it, moved
it slightly rearward, with no apparent affect.
An e-mail to Kenwood got the response that the item was considered vintage
Kenwood gear and therefore beyond repair!!
