Excellent product  Time owned: 0 to 3 months
I should have bought this tuner last year when I bought my 817nd. It tunes everything I connect to it. Nothing against my two MFJ tuners, but this little tuner goes hand in glove with the Yaesu 817. It's very easy to set-up, instructions are clear, and it appears to be of quality manufacture.

Great  Time owned: 0 to 3 months
This Tuner is very good. When using it with the Yaesu FT-817Nd you need to go to menu #14 and select 38400 for the baud rate for it to work.GREAT TUNER

Fabulous tuner. Works every time  Time owned: 6 to 12 months
A small and easily carried tuner that sits atop the 817 very nicely. It will work with other radios too of course, like my IC 703!

The z817 tunes quickly and quietly and I have had it tune everything from random wire kite aerials to stubby mobile whips in my 4x4. Every time it just works well, it does what it is meant to do!

I have used ( and use still) manual ATUs and long wire tuners as well as other auto tuners but the z817 is one of the easiest and neatest. It beats manual tuners for mobile work hands down. Combined with a rig-front SWR display it's a winning combination for the car. I wish the icon 703 built in ATU was as good !

Great tuner  Time owned: 0 to 3 months
This tuner works very well with the FT-817. It easily tunes any of my four antennas quickly. Not too many mentions of one of the best features of the Z-817 is the additional CAT port. Just plug the CAT cable from the computer into the tuner and connect the supplied CAT cable to the port on the 817. Perfect CAT operation and a one button tune function for the 817.

Also a word of recommendation for W4RT where I purchased the Z-817. I ordered on Friday and had the tuner in hand on Monday- W4RT to Texas via USPS with FREE shipping and the best price. You can't beat that anywhere.

The Perfect QRP Tuner  Time owned: 3 to 6 months
Ive had this tuner for just over two months now. I mainly use my FT-817 in the shack with a Cobwebb antenna but i've been portable a few times where i've used dipole antennas and even a fence in a field connected to RG-58 feeder and this tuner tuned them no problem - this thing would tune a wet piece of string! The tuner comes well packed with instruction manual and interface cable which can be a bit tricky to fit to the radio due to the small pins. All that's needed is a press on the tune button for a second and this tuner tunes in an instant and it also stores upto 2000 memories which makes tuning even quicker on you're favourite frequencies. Due to it's small size and light weight this tuner is perfect for portable operation and will tune with a maximum power of 20 Watts right from 0-30 MHz and 6 Metres. Before i bought this tuner i was looking at other portable tuners but im glad that i bought this one. If you have an FT-817 and you're looking to buy a tuner - buy one of these you won't be dissapointed.

Another good LDG tuner.  Time owned: more than 12 months
I have had this tuner for a year now. It has done a great job of matching up hamstick dipoles and full sized homebrew dipoles in various locations while using it with the FT-817 on SSB and PSK-31. This year I had one problem occur while operating portable. The ANT. connector came free while removing the UHF connector to the dipole. I struggled to remove the old broken wire and solder the lead to the pin as I have lost the use of my left due to a stroke after Christmas. I was successful finally and was able to make a few contacts on the Georgia QSO party. All was just like new again. The AA cells were still metering in the Green I put a little Loc-tite on the connector just in case. If any lossen I will replace the connectors with pop-rivets and star washers through the mount plate. This is my third LDG tuner since going auto tuning.

Can it core a apple?  Time owned: 6 to 12 months

Yes it can Chef of the future!! I purchased mine from Cheap ham .com and love it. It comes with the interface cable which will force the 817 into tune mode whenever the button on the tuner is pressed. Its tiny and works as advertised. I wish this was built in the square case like the picture on the box as that would make it easier to stack when portable. The batteries last forever, they are in mine since I bought it.

A good tuner  Time owned: more than 12 months
I've had my z817 since a few weeks after they were announced.

The tuner works and seems to work quite well. I have several tuners and I prefer my ldg z-11 pro because it automatically tunes without requiring me to do anything.


The z817 does a great job. In preparation for a move -- I'll only be able to hand carry my ft817 and z817 (all my other radio's will be shipped) -- I've been using my ft817/z817 exclusively.

Pushing the button and holding it when I change bands isn't really that much of a pain.

The tuner works, it seems to work as well as any of my other tuners. I find it a big bigger than my z-11 pro -- which is longer and wider, but apparently, just a fraction of inch shorter and that allows the z-11 to fit in a case with the ft817 that I can't get both the ft817 and z817 in at the same time.

The pass through port works great. You have to becareful when plugging things in - everything is small and you can't really tell when something is plugged in correctly.

When I received my z817, I attempted to attach my coax feedline. Somehow, the pl259 screw connector became bent -- so it doesn't screw on easily; I didn't realize this with the z817 -- and when I tried to disconnect the pl259 because it was binding, the so239 connector on the z817 turned. So, I had to take the unit apart and resolder the internal antenna connector and snug down the so239.

If you have the tools -- I'd strongly suggest taking off the stock so239 and replace it with one with four screws -- in the long run, if something happens, you'll be thankful.

I like the z817, it works for me. I've been using it exclusively for the past several weeks.

If you have an ft817, I recommend it.

Great  Time owned: 0 to 3 months
If you're in doubt between the Z817 and the Electraft T1 for your FT-817,
remember that the Z-817 has a PASS TROUGH connection for computer control.
With the T1 and an (optional) computer cable, you either have computer control or automatic tuning. NOT BOTH!
