MFJ-941E MFJ941E MFJ Enterprises Original HF Antenna Tuner with Mini Cross Meter, 300 Watts

GOOD YO GO!

Well, hams often say MFJ stands for Mighty Fine Junk and in this case they are right. The tuner is VERY twitchy when moving the knobs trying to tune different bands. My antenna is resonant on 20 and 40 meters, but other bands are hard to get right without a matching unit, which is why I got this tuner. My radio wont transmit if there is a mismatch greater than 3:1. Even though the MFJ says it has tuned to 1:1, the radio often sees SWR great than 3:1 and will shut off transmit. On some knob positions, when trying to tune, the needles pulse like theyre following a regular dance beat or something. This unit acts much worse than my older 945E which I moved to my QRP unit out in the shack. This was an open box return from Ham Radio Outlet, so I guess Im stuck with it. Going to open it up, clean it out and hope for the best.

After reading about issues with the inductor selector switch, that was the first thing I checked. Mine operates smoothly with positive detents. The antenna selector isnt as smooth. The meter backlight on the tuner I received is a nice white LED. It shows very nicely using a 5 volt power source and is really makes the meters easy to read at 12 volts. 80 through 10 meters tune nicely on my short compromise wire antenna. 10 meters is VERY sharp....patience is called for, but it will tune! My antenna is too short to get anywhere near a decent match on 160 meters. Overall, I really like this tuner so far.

Came fast and good package. It was a gift to my dad and he really like it.

Item shipped and arrived as scheduled, but product was defective and I have returned it for refund. Bought it to replace an MFJ-949 tuner than died (balun burned up). New, defective tuner would not tune existing antenna on any bands. Adjustments of inductor nor either capacitor had any effect on any band. Either the built-in SWR meter is bad or, more likely, the tuner itself.

Works great. Tunes my antenna quick and easy. You could probably tune your rain gutters or a coat hanger with this tuner.

Tunes antenna when my radio cant

Super easy to use. Good quality. Works like a dream.

Nice addition to my shack
