MFJ 989C VERSATUNER Manual for —-

This world-famous 3 KW MFJ-989C VersaTuner V features two massive transmitting capacitors and a roller inductor with a three digit counter. A roller inductor lets you tune your SWR down to the absolute minimum–something a tapped inductor tuner just can’t do. A 3 digit turns counter plus a spinner knob gives you precise inductance control — so you can quickly retune to your favorite frequency. You won’t have arcing problems with this roller inductor. That’s because firm springs put considerable pressure on a plated contact wheel. This gives you excellent electrical contact with the roller inductor wire and eliminates arcing problems. Wide low inductance straps are used for high current connections. A new core gives you excellent RF properties for minimum loss. Ball bearings on both the front and back shafts give you a velvet smooth vernier feel. Steel end plates and steel shafts give you lifetime durability. This High-Q roller inductor is mounted horizontally and centered vertically away from metal surfaces to maintain highest Q for maximum efficiency so you’ll get full power out.
