Re: [Elecraft] K3/KPA500 with a MFJ-994B AUTO TUNER
I currently have a K3/KPA500/MFJ998 set-up. I used a MFJ-994B with an ALS-600 for several years. A couple of years ago I upgraded to a MFJ-998 as it has a built-in amp-disable feature when tuning. I do like these autotuners and I have reviews of both in the Product Review section of my website at www.ad5x.com. To me, the disadvantage of the MFJ tuners is that they do not work on 6-meters and the bypassed SWR of the tuners is high on 6-meters. Therfore you must completely physically bypass the MFJ tuners when operating on 6-meters (I do this with antenna switches).

de KF1C Running K3 w/ ALS-600 Mfj-994B in a plastic box at base of 43ft vertical / and 99 ft inverted L. Fed against 2 above ground radials 135 ft long and 2 65 ft long. (also 5 or 6 60 ft buried) Inside the shack 100 ft of coax make not much differance on these readings, I spent allot of time back and forth. I have line isolators in line (both coax and ferrite ) so I know its not rf on the shield causing the trips. 994B loses lock and trips the amp above the following readings. The 994B does not have a wide matching range like the 998 if you read the specs. I am waiting for the KAT-500 to come out. 43 ft vertical 994B handles 500 watts 10m 12m 15m 17m 20m 994B handles 200 watts 30m and 40m 994B handles50 watts on 80m Inverted L 99 ft 994B handles 500 watts 10m 12m 15m 17m 20m 40m 994B handles 75 watts 80m and 160m Both Inverted L and 43ft vertical connected. 994B handles 500 watts 10m 12m 15m 17m 20m 40m 994B handles 200 watts 80m and 160m I'm going to extend the L to quarter wave on 160m soon, that should (hopefully) allow full power on 80m __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

I use the LDG AT600 pro and it works fine. I avoid MFJ if I can. Some stuff is fine other stuff is wellnot. If you have not purchased one you might consider waiting for the KAT500 that Elecraft is working on.
