Can anyone tell me how to adjust the mfj998 tuner so that it will tune the 160 mtr band. I've looked in my manual and don't seem to find the part that tells how to do that. The tuner is suppose to tune it but as it came from MFJ new it want do that. wi5d Thanks |

This article by Phil AD5X explains that a tuner with only 25 uH of inductance needs a vertical to be at least 80 feet long--he shows how to add another 30 uH for matching a 43 foot vertical to 160 meters. http://www.ad5x.com/images/Presentations/Remote%20Tuners.PDF Zack Lau W1VT ARRL Senior Lab Engineer |
