Nice tuner  Time owned: 0 to 3 months
This is my first auto-tuner, other than the limited range ones I've had in my HF rigs.. My antennas consist of a trap loaded inverted vee and a 6 element trap yagi at 50 feet. I don't need the tuner on the beam except for the edges of 10 meters, but on the vee, it is a needed item. This tuner more than fills the bill, I now can quickly obtain a low SWR on the vee for 40 & 80 meters. As an added bonus, it's tuning range allows me to now play on the WARC bands.
It replaced a MFJ 948 VERSA II manual tuner that I had for many trouble free years and so far I've found no issues or complaints with the 929.

Great Tuner  Time owned: more than 12 months
This tuner is outstanding. After two years the power switch went south. I called MFJ tech support and was shipped a new switch on Friday. I received the new switch Monday. There always seems to be a lot of jokes and trash talk about MFJ. I want to say they stood by this product and earned my respect since it was out of warranty and they could have charged me anything for this switch. They were professional and as stated above quick. Great job MFJ.

Great once you fix MFJ's screwups  Time owned: 3 to 6 months
I have 2 MFJ-929's now, they actually replaced some LDG's that failed to tune antennas as well as a built in tuner of my FTDX5000MP. But I needed tuners for some other rigs so took a gamble on MFJ.

Well they worked and tuned my antennas as well as the Yaesu. One interfaces to a IC-7200 very nicely, the other is on a TR-7.

Issues out of the box were with the calibration, luckily MFJ gives you instruction in the book. You must calibrate as MFJ doesnt have a clue how to do it themselves. Second, and before you power these up, take the cover off and fix all the screws inside. Mose were loose or barely in. The case screws were also all cock-eyed. Not sure what MFJ is doing at the factory but their QC is horrible.

I think MFJ has great ideas but the absolute worst execution. maybe they should sell their items as partial kits to allow hams to assemble themselves. It would save from the required inspection when you receive a MFJ item.

And don't bother calling MFJ customer support, it is worthless. Sorry MFJ, but you need help with QC and customer support.

All that said, I would give this a 5 if it were not for the out of the box issues (which can easily be resolved).

Works with FTDX1200  Time owned: 0 to 3 months
First unit was dead out of the box, ended up exchanging it for another.

Second one works well and tunes quickly. No issues with connecting to the Yaesu FTDX1200, Use the MFJ-5114 cable and follow the directions for connecting to the FT950. The menus on the two radios however are not the same. To select a external tuner on the FTDX1200 is option 179 on the menu.

IC-7100 Use OK !  Time owned: more than 12 months
Update at the end of 2013... got a new IC-7100, and with the jumper OFF (as specified for the IC-7000) it tunes the DX Engineering 43 foot vertical on everything from 160-10 (which the LDG AT-600ProII refused to do). Again, great value for the $$, and connects to ANY rig with the appropriate cable (unlike LDG).

Sweet Little Auto Tuner  Time owned: 3 to 6 months
Perfect Hassle-free use, this Auto Tuner is so easy to use and so very quick to tune on any band. I use a Hustler 5BTV antenna and an IC-7000 and Yaesu FT-920. I stuck the Hustler into the ground and never got a chance to tune it properly, so I relied on the Auto-Tuner in the FT-920, which was just OK, but the SWR was quite high on some bands and completely unusable on others. I bought a used Kenwood AT-200 ATU which had a better tuning range than the internal one on the FT-920, but some bands still wouldn't tune. The I bought the Icom IC-7000 and what a great radio that is!. Of course it doesn't have a built-in tuner so I bought a used MFJ-929 on the internet and when it arrived it actually turned out to be brand new and un-opened, excellent! I had some old computer power supplies, so I cut off one of the Molex connector cables, snipped a bit of the plastic casing off one end of it and connected the cable to some CAT cable using Gel Crimps, I crimped a crystal RJ-45 connector to the end of the CAT 5 cable and my Radio Interface cable was ready, in less than 10 minutes. I had intended on buying a ready-made cable, but never bothered as the one I gunthered works 100%. I went into the MFJ-929's menu and selected "Icom", connected the coax and the Radio Interface cable, then switched on my IC-7000 and this automatically switched on the MFJ-929 Intellituner. The first time you use it on any frequency it can take a couple of seconds to tune, but after that it's lightening fast! I tried to time it, but it's way too fast, but definitely under 500ms, very impressive. it tunes my IC-7000 to any band whatsoever with an SWR of less than 1:1.3 and if I click tune again it tunes almost any band to 1:1.0. Tuning is so easy: I use the Ham Radio Deluxe software and when I click on a station in the DX Cluster list, if it's far off the frequency from when I last used it, I just use my mouse to click on the "Tune" button in HRD and milliseconds later it's tuned. I absolutely love it. It makes it so easy to change bands.
The build quality is great, no paint scratches, no sharp edges. I have only used the power button once, since when I turn on my radio it turns on the Auto-tuner.
I have only had one issue and it's not really an issue at all: I had originally opened up the 929 to remove jumper 4, as per the instructions when using an IC-7000, but there was no jumper 4, just the holes on the circuit board where it should be, so I had nothing to do here. like I said it wasn't really an issue.
I haven't used the FT-920 since I got the 929, only my IC-7000. The two compliment each other beautifully and make my Ham Radio experiences so much better, I would highly recommend this little beauty!
I am on the look out for a nice solid state amp, maybe the 400 watt Tokyo units, and will need a higher rating Intellituner, but the bigger version, the MFJ-994B, doesn't have the LCD display and several other features, which I just can't get my head around. The 1500watt version, the MFJ-998 has all the features of the MFJ-929, so why the middle power units is so lacking doesn't make sense, I would buy one in a heart beat otherwise, (I'm restricted to 400 watts)
So, if you need a 200 watt Auto Tuner: buy one today!

Terrible- died in 31 days  Time owned: 0 to 3 months
I rate this a 0 on functionality, 0 on Quality and a 0 on their warranty service

First issue is their sticky tune, it hates g5s. So it would only tune if i did each band manually. I should have taken it back then and there.

I bought this new in sept. Exactly 31 days after purchasing it , the power switch broke. So i had to send it back to MFJ. I overnight-ed it via the USPS in hopes of getting it back fast. The USPS record shows it was delivered on Oct 29th. But They(MFJ) didn't log it into their "repair system" until Nov 7th according to the invoice MFJ sent me
I called on nov 27 inquiring about it. They claimed they didn't get it. Then they say it is on hold since they spelled my name wrong in their system and couldn't touch it until i called and they will look at it.
I called again Dec 4th, they hadn't even looked at it. Then they said they would, but they are all out power switches and it will take an additional 2 to 3 weeks.
So now we are out to new years time estimate. and they state they will not extend the warranty for the 6 weeks plus they have had it because it is against their policy

So if you have money to burn, it did manual tune nicely but that is it. Don't expect any service support for repairs, unless you have a lot of time to wait

I will save up and buy an LDG... But no DXing for me until next year now.

Not that bad after all...  Time owned: more than 12 months
A year ago I wrote that my MFJ929 had suddenly left me after two years of reliable service. I had it repaired by the dealer (for about a quarter of the retail price) and it serves me well again for almost a year. I use it as a remote tuner for my horizontal delta loop. It is controlled by my IC-7200 via a 30m long CAT6 cable running in parallel with the coax feeder. Tuning is as easy as pushing the "tune"-button on the IC-7200 for two seconds. Works quite well now. If it had not failed earlier I probably would have given it a five again.

World's Biggest Sucker  Time owned: 0 to 3 months
After 20 years of poor to disasterous experiences with MFJ equipment I swore I would never buy any more. Recently I had an opportunity to use the MFJ-929 tuner at a friend's station and like an idiot I convinced myself to purchase one for my shack. DEAD OUT OF THE BOX. I get the morse message "WAKEUP FAIL" when I run the self test. No other functions work at all. My instruction manual tells me this is a microprocessor wakeup circuitry problem. That is an encouraging dianostic, isn;t it?!?!?

So now I am in for another fight with MFJ to try to get this piece of junk replaced so maybe I can get a few days of use out of it for my $218.00! Beware of MFJ, you all have heard the horror stories and I assure you they are true. Once again I am swearing off. I prefer buying American as well but I sure do not like throwing my money down a rat-hole.

Great little tuner!  Time owned: more than 12 months
This is a great little tuner and very useful for basic impedance matching duties in my station. The number one issue with this tuner to remember is that it can not perform auto-tuning functions with more than 10W applied. This is very important.
I like the two antenna port feature, antenna port #1 is connected to my old Dentron Clipperton L amplifier, it works great on all bands 160 10 M. One does have to turn off the auto-tuner during initial loading-up of the amplifier. Once that is task is completed the tuner is activated and 10W qrp power is applied, the tuner will quickly tune the SWR down to less than 1.5:1 and away you go.
This past year at field day we used this autotuner as both a tuner and an antenna switch. On antenna port #1 we had a Cushcraft A-3 tribander and on port #2 we had a dual band 80/40 meter fanned inverted vee. It worked great. Band changes were a sintch with a push of a button we could swap antennas (if we needed to), reduce transmitter power to 10W, key the transmitter allow the tuner to do it's thing, and in less than 4 seconds we were good to go on another band. It was that easy and convenient.
Have I encountered impedance mis-matches that this tuner was unable to handle? YES. Coat hangers on 160 don't work.
Overall it is a good little tuner and I recommend it if you are using a solid state radio without a internal tuner. It is a good little final PA insurance device.
