MFJ-936C Deluxe High-Efficiency Magnetic Loop Tuner Instruction & Technical Manual
Step 7 You can now enjoy operating in your favorite mode. However, if you change frequency
more than about 5 kHz, you may find you will need to re-adjust the TUNING controls for
minimum SWR. Rotate the TUNING control clockwise for higher frequencies and counter
clockwise for lower frequencies. Even greater frequency excursions can cause the MATCHING
control to also require adjustment. This concludes the MFJ–936C High-Efficiency Magnetic Loop
Tuner™ operating instructions.
