I have not tested any of them except the speakers, which tested good, and don't know a lot about this stuff. The fellow I bought them from said they came as part of his inheritance from his father-in-law. Each line item is in a separate auction with the item in this auction highlighted.

Lighted meter with on/off switch (Light uses 12 VDC or 110 VAC with optional MFJ-1312D). The back panel has outputs for two coaxial cables, one wire or balanced line and dummy load are provided. The peak and average reading cross-needle SWR/power meter has forward power ranges of 200 and 2,000 watts. Plus you get a built-in 50 ohm 300 watt dummy load that makes exciter tuning fast and easy.įrequency range is 1.8 to 30 MHz. It lets you select two coax antennas direct or through the tuner, balanced line or random wire and dummy load. You get a two wafer ceramic antenna switch with extra large switch contacts to eliminate plugging and unplugging antennas. It lets you operate high power into balanced feed lines without core saturation or voltage breakdown. It's made with two giant 2 inch powder iron toroid cores and wound with teflon wire connected to high voltage ceramic feed thru insulators. You get a super heavy duty balun for balanced lines. You can select a low Q when you want convenient broadband coverage or select high Q when you need an extra measure of harmonic attenuation-it's your choice. You can tune your SWR down to the absolute minimum from 1.8 to 30 MHz, including MARS and the WARC bands. With three continuously variable components-two variable capacitors and a roller inductor-you get the widest matching range and the most precise control over SWR possible. 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. Steel end plates and steel shafts give you lifetime durability. Ball bearings on both the front and back shafts give you a velvet smooth vernier feel. A new core gives you excellent RF properties for minimum loss. Wide low inductance straps are used for high current connections. This gives you excellent electrical contact with the roller inductor wire and eliminates arcing problems. That's because firm springs put considerable pressure on a plated contact wheel. You won't have arcing problems with this roller inductor. A 3 digit turns counter plus a spinner knob gives you precise inductance control - so you can quickly retune to your favorite frequency. A roller inductor lets you tune your SWR down to the absolute minimum-something a tapped inductor tuner just can't do. This world-famous 3 KW MFJ-989C VersaTuner V features two massive transmitting capacitors and a roller inductor with a three digit counter. View Meter | View Counter | View Switch | Back Panel
