Need to have Nifty card  Time owned: 3 to 6 months
Got this for my first outboard auto tuner. Try to remember if you have it on manual or auto, and then be sure to watch lights, as they do their thing quickly. That's the only quick thing for me, half the time, as when I do a "new" frequency, it usually chatters for about 8-9 seconds, then finally stops with a 2 to 3:1 reading?? This is on a "store bought" 80-10 dipole. Same for homebrew 40m. Gonna re-read the manual again..and again...see if I missed something. May just use my manual Ten Tec inline.

Cheap Junk  Time owned: 0 to 3 months
Tuner just keeps on tuning even after manual tuning. Would not tune 11m antenna to 10m band, just keep making noise. I really can't understand why some of these company's claim to have a great product, but in actuality they sell garbage ie: LDG and MFJ. After I took it back for a refund I found a $35 Dentron JR Monitor on ebay, this thing will tune anything. I will never buy LDG again.

Excellent tuner!!  Time owned: 0 to 3 months
I purchased this tuner in combination with a S9 31' vertical antenna. I put a large waterproof electrical box at the base of the antenna and a 12 volt power supply. I then used the LDG 1:1 balun and connected the antenna to the tuner. This setup is working amazingly well in my antenna strict neighborhood! I currently can tune 6m-75m without a problem and have good signal reports on all bands. I cannot tune 160m yet but I have a 4:1 balun to try and I'm sure this will bring the 160 meter world into play. I drive all this with a Icom 746 Pro, I start with low power (20w) then after the tuner find the match increase to full power and always get below a 1.5 to 1. It does take the tuner a few seconds to find a new match but stored matches are restored instantly on transmit. Very happy with the combination and LDG was super about answering my questions before buying.

Great simple auto-tuner  Time owned: more than 12 months
I've operated this tuner with the FT-857D and FT-817ND portable and it has always worked flawlessly. I recently sent away for the upgrade IC (cheap upgrade!) and find that it tunes faster with a variety of portable verticals and dipoles. I just love this rugged, fast, quick autotuner !

OK but power limited  Time owned: 6 to 12 months
The tuner works as advertised but watch your power output!! I burnt up a toroid using 30 watts PSK on 80 meters with a homemade 43ft. veritcal. LDG was GREAT in repairing and sending back no charge..

Unfortunately I smoked it again on 17 meters digital....low power too..not as bad this time so I will keep it in case I ever go portoble with low power one day.

The advertised 125 watt power capability applies maybe for short duration cw and ssb, but for digi modes keep that power below 25 watts and you will be fine.

For me, I just finished a very robust homebrew T tuner and no problems at 100 watts.

Works very well inc. contesting calling CQ  Time owned: 6 to 12 months
Bought it primarily for portable contesting use for HF and 6M using my 100' inverted-vee wire antenna fed with 300 ohm twin lead, 1:1 choke balun and a short 8' length of coax. Solid auto-matches <1.5:1 each time after initially working my way up each band (80M thru 6M, including all WARC bands), on low power before QRO operating. I use car booster pack with 12V cigarette plugs for both my LDG Z-11 Pro II tuner and my Hamgadgets auto-keyer. Recently during FD, it stretched our club 80-40-20-15 fan/trapped dipole to full bandwidth across 80-6M FD bands (although I couldn't get it to match on 160M). Always grounded to radio and a ground rod of some kind. Works quite well, with minimal heat build-up, even when holding a contest frequency for 45-60 mins using full 100W -- works as advertised. I'm very happy with my purchase and got a free, promotional LDG balun to boot!

Pretty good but not for running  Time owned: more than 12 months
This tuner pretty much matches everything. Two things to look for.

1. It searches for match endlessly when the voltage is < 8.2 V. With built-in 6 AA batteries, this is half-full (or half empty). No low-battery warnings.

2. Works well in casual QSOs or S&P but easily overheats when running in a contest.

Very useful auto matcher  Time owned: more than 12 months

I've owned one of these devices for several years and I've already reviewed it on these pages. I like it so much that Ive bought another one!

It's an impedance matching device, not an 'antenna tuner', despite what the manufacturers say or claim. In fact' it's just a simple L-match circuit, relay-driven by a PIC MPU that takes VSWR info from a simple toroid based bridge circuit.

Once you have used an automatic matcher, you won't want to use a manual one.

Yesterday, at a local radio rally, I bought my second LDG Z-11 Pro, this one being a mark II version. My reasoning for this is that I also like to work /P, and life is too short to use manual matchers :-) I plan to use it with a vertical whip mounted on a salvaged military radio carrier frame with a trailing counterpoise.

I've fitted my Z-11's with battery packs made from alkaline AA cells soldered in a series string and wrapped in PVC tape. This allows completely self-contained operation without the need for an external battery or cables. My battery pack is held in place by a pair of ty-wraps wrapped around the PCB and over the battery pack.

I still don't much like the manual supplied with this AMU. It could be better, hence the 4. The actual product has worked very well for me since I purchased my first one, which is used mainly with my FT-102 transceiver.

If I could give this a 4.5 I would, but the manual is a disappointment.

Exceptional manufacture  Time owned: more than 12 months
I bought the LDG Z11pro tuner about three years ago to use with my FT-817 backpack station..used it for two summers and it stopped working..It more than likely was my fault..I think I push it to hard into a high SWR situation..After procrastinating for six months I decided to send it in for repair about three weeks ago..because I,m planning to sell the 817 portable station..I just received a box from UPS..The service slip from LDG Electronics read.." Unit not repairable..replace with new Z11-pro2 unit at no charge to customer " Now..You can't beat that for a company that stands behind there product..I was not expecting that at all..LDG Electronics will always get my business in the future..I did buy the AT-200 pro to use with FT-857D..LDG Electronics is GREAT..I give them the BIG THUMBS UP..!!!!!!!
