Excellent tutorial. I am recently back into ham radio after quite a while of being away. I just purchased an FT-891 with this tuner. Could not be happier. I watched reviews on this tuner and the Pro ii version. Candidly, the pro version just didn't seem as efficient as the Z-100 plus. I am primarily interested in POTA right now so I wanted something with a simple interface. This met the need hands down.
Love the video, thank you so much. I was looking to get the Yaesu FC-50, but it can only do 3:1 matching (someone called it a "touch-up tuner", which sounds about right), whereas this little guy seems to be able to do more (10:1). The real selling point for me is that it can be powered by an internal 9V battery. I will do anything to avoid having to many cables and wires hanging around if i can, so this is a great option for me. Thank you for the little demo, this has helped me with my decision. 73s, 9A5ELO.
Thanks for the video. I'm looking at using this tuner with my 891. The manual says that you should put a carrier wave on AM, FM or other during the tuning process, but I noticed you didn't. Looks like it tuned just fine without doing that?
Nice little tuner. Considering getting one for camping. But why do you use a separate wire to connect radio's and tuner's ground since the coax' outern shield did it already?
I have a question, how do I protect my AT (old version) LDG Z 100 with 10 watts on CW? where do I set it on the FT 891? 80 watts is probably a bit too much for tuning. Translated by Google Sorry
Hi, both tuner are still working flawlessly the Z100 tends to get used when I'm mobile and the Z11 is my favorite when I'm portable. I really like to be able to fine tune the match, the Z11 lets me do that. 73 de VE3BF
@@VE3BF I wish I had gone that route. A 2:1 isn't very good in my opinion. Usually the z100plus gets me a 1.5:1 or better which to me should be a Auto Tuners standard. Does the Z11 interface with the FT-891?
You should ask if the frequency is in use and give your call sign. Not hearing anyone is not enough to just tune up... Please follow the rules. Otherwise great video.

Yes that it 100% correct. Not everyone can have an antenna that is 100% resonate on all frequencies or bands, some of us have to make compromises due to budget, space, bi-laws, time and so on. An antenna tuner will match the antenna so that you can at least get on the air, better to get operating at a reduced efficiency than not operating at all. 73 VE3BF
When you hit the match button to activate the tuner, does the tuner match the entire spectrum on the 40-meter band (7.125 thru 7.300)? The antenna is matched no matter what incremental frequency I'm at? If so, would that procedure be correct for every ham band? Why would it then need 100+ memories? Thank you.
I have this set up and I have to say this is one of the best radio/tuner combo for portable operations. I can put this entire rig with an antenna, solar panel and battery all in an airline friendly backpack. Great grab and go setup and you never feel under gunned like you do with a smaller QRP rig.
Great video! I believe the Z-100Plus will make you happy. I use the earlier model LDG YT-100 for my Yaesu FT-857 to fantastic results. 85' random wire or 43' random wire using 4:1 Unun and the Wolf River Silver Bullet Mini+102" whip all operate fine. I made Saratoga, NY to Namibia (8,000 miles) from a park bench with that rig and tuner using the 43' endfed at 100W. I don't need anything more from a portable rig. 73 from N1DEL.
Thanks very much for the detailed run-through! Just a little FYI/BTW: of course the ATU is only matching the input impedance to the feedline to the ~50 Ohms at the radio's RF output. An impedance match on any band for which the antenna is NOT designed to operate will result in much-reduced power radiation, with an unpredictable pattern. Sure, you won't upset your radio....but people need to realise that impedance matching does NOT equate to tuning a piece of wire to resonate on the desired frequency and operating efficiently. Thanks again for your well-presented video! 73 from VK-land
The tuner reflects the reflected wave back up the coax to the antenna. The losses would be in the coax. Other than the coax losses all your power makes it to the antenna. How good the antenna is at the freq of operation is a different story.
New FT891 owner - can't put antennas up in my apartment so I'll be doing portable operations for a while - and I just happen to have purchased this same tuner. This tutorial is PERFECT for me! Excited to get a good antenna and go out to a local park to give it a workout. Thanks! Tom W7BHN

All this does is add extra protection against a high SWR to the finals of your transceiver. And an AA battery is 1.5V, which means eight of them in series is 12V, not 9V.
Are you manually reducing radio power before tuning? The manual says that when using the Y-ACC interface cable that pushing the TUNE button, the radio is keyed at its “current power setting.” I am concerned about transmitting 100 watts into a hi SWR while it tunes. Have you had any issues?
Dennis I paired this with my FT-891 and it works like an LDG is expected too. From an 8 ft wire to 250 feet of wire without a hick up. I suggest you pack a 1:1 and 4:1 LDG balun in the go box for those times you need it.
I know I am a dinosaur. But I prefer a manual antenna turner. I just like the experiance of fiddling with the dials to find the lowest SWR and seeing it on and actual meter. Just lights makes me suspicious.
Yeah some meters in some radios aren't very accurate but so far the one in my FT-891 seems right on the money. One advantage I have found a Auto Tuner gives is faster tune up. Running on battery power that is a plus. Its been times on a high mismatch I almost drained my bats trying to fix the problem and get tuned up. Im thinking I would be better off with a store bought resonant antenna but hate to spend the money on it. I love building my own but I spend way to much time tinkering with them and not nearly enough time on the air. lol WW5RM
I use the same tuner on the same radio, by watching i am making a use correction. The LDG tuner instructions were different and complex. Thanks for making it more simplified. 73

HI, thanks for the video, 2018... now 2022.. I have an LDG KT-100, do you know if these models are all the same and the supplied interface dictates the model ie KT, YT etc.. asking if perhaps my KT-100 (looks identical to the Z100 Plus) would work on the FT 891 with appropriate cables..? currently plug and play on a Kenwood TS-50.. thank you for the videos, you have a nice calm manner that is easy to watch/listen to and casually very informative..
The KT-100 has the interface for Kenwood radios, the YT-100 was for the previous generation of Yaesu radios, neither will work with the FT-891. Thanks for your kind words. 73
Your videos are great. I am considering this set up with a dipole, and I have 2 questions. Would you go with this setup again and why not pull DC from the same line that feeds your FT-891? I noticed you like the Z11 Pro II in another video.
I think he did that so he wouldn't have to splice in is my guess. Probably had the battery pack laying around. I just sliced in some crimp terminals and run off the same power.
If your set up is permanent then yes splice into the 12 volts for sure. My setup are mostly portable so I use the internal battery pack or one of the portable packs that I've made up. The Z-100 and the Z-11 are both very good tuners and I'd buy them again if I had too replace them. 73 de VE3BF
JUST got my FT-891 and LDG Z-100 - still haven't warmed it up. I'll definitely get the interface cable - or build one (I probably have some jacks somewhere). Is that a Yaesu cable or an LDG cable? Enjoy and 73!
I have the 100A. Different cable set-up. There is what looks like an S-video plug on the tuner end, then a different plug on the radio end, with anther 3.5 (like yours) attached. For this one, you need both plugged in on the radio for it to do things more automatically. I got there, but it took some playing. Thanks fort the help.
Hi Dennis, thanks for the valuable information! Would you recommend this tuner or the Z-11ProII to pair with an FT-891? What are the relative merits of each?
Hi Dennis, I did the Mars Mod, That came out perfect, but when I did the factory reset, I forgot to put the Radio back to "LAMP" mode, this video helped me , so a BIG THANK YOU for this video.de ZF1PB
Thanks for the great video. Quick question: When you said you were concerned that the ground connection (your wire from LDG to back of radio) might interfere with the antenna can you explain and how would you recommend connecting the ground wire to the radio? Thanks again for this video. 73
Great Video Dennis! Do you lower your power to tune or tune at high power? I always lower my power to 5 watts before tuning and wonder if I am just wasting my time.
No need to change your power settings the tuner interface does that for you. When you hit the tune button the rig drops down to 5 watts, once the tuning is do the rig goes back to whatever your you had it set at.
I made a mistake and bought the MFJ-939Y. It has irritated me no end. Half the time it just stops working or the TNR in the 891 disappears. I have to manually do the pushbutton thing everytime i change freqs for it to tune. The autotune function just wont work. YES i have checked many times the jumper settings in the tuner. They are correct and the cables are the correct cables and the setup in the 891 is set to tune. I give up.
Not sure if this was mentioned previously but you cannot transmit on 80 meters with a 20 meter antenna. All the tuner does is make the radio happy. You are NOT tuning the antenna. If you hook up an antenna analyzer that shows reflected power, you will see there is no forward power and all the power is being reflected back. Tuners are great to fine tune but there is no tuner that tunes the antenna. All they do is keep your finals from burning up.
any problems wiht the tuner locking up with an audio tone? i have the same set up and it all of a sudden has an audio tone and it does not stop tuning. any help will be appricated. kn4lwj
Thanks. Your presentation is simple and very understandable. I am looking to add a tuner to my FT-891. You mention that your SWR reading on your transceiver is high. How did you determine that? Again, thanks.
I'm late to the game. You're quite skilled at creating good videos Dennis. Can you mount the ldg z100 in the trunk along with the FT-891 body? 891 face plate is on the dash. How to engage the tuner when the tuner is in the trunk? (The tune button would be on the tuner in the trunk.) Thanks. Tim K3JTA
You don't really need the radio interface cable, right? Just press "tune" on the tuner while transmitting in AM or CW mode once you're on whatever frequency you want to transmit on?
If you don’t use the cable then you will need to reduce your power output to 5 or 10 watts, select cw mode, key the rig for the tuning process then return to the power and mode of choice.
@@VE3BF got it. Yep my kx3 has a "tune" function for when you're using an external tuner. It puts out a carrier at low power. Does the 891 have a similar function or do you have to do this manually?
@@gabes80 No, you have to do it manually on the 891 unless of course you have a compatible tuner. with a compatible tuner and cable I simply press the tune button and le the magic happen :)
the Yeasu cable wired different the a standard audio cable. you can find the wiring diagram on the web and solder a cable yourself. Just remember to mark each end, one for tuner and one for radio, the cable does not work in reverse. When done correctly there is no need to drop the power for tuning or keying the mic, the tuner will do all of that automatically. 73
@@VE3BF thanks for the reply. So the Yaesu style cable is necessary, got it. Now I ask, do you think it’s better to have the alc cable than just holding the tune button and keying the mic? Is the only benifit to the cable having the power drop without going through the motions myself? Or is they another benefit. Holding the tuner button and keying AM is pretty simple.
Very good info on the Tuner and the radio I'm getting my FT-891 tomorrow. I think I can run it without looking at the manual with your great instructions on your videos. I probably get the Z-100 if I get a different antenna that needs a tuner. Sounds like the LDG Balun is a great add-on. I have the Wolf River Coils SB1000 with the mega tripod stand and an Rigexpert AA-55 Zoom to check resonance.
Thanks for the informative review. I think the Z-100Plus will be just right for my 891. I operate portable with a Bushcomm Highlander 8 vertical on an Alpha Delta Outpost ground-coupled tripod mount.

How to engage the tuner when the tuner is in the trunk? (The tune button would be on the tuner in the trunk.) Thanks. Tim K3JTA
Do you have to have the interface cable ? If your using a HR-2510 for example on 10 meter ?
You don't really need the radio interface cable, right? Just press "tune" on the tuner while transmitting in AM or CW mode once you're on whatever frequency you want to transmit on?
If you don’t use the cable then you will need to reduce your power output to 5 or 10 watts, select cw mode, key the rig for the tuning process then return to the power and mode of choice.
@@VE3BF got it. Yep my kx3 has a "tune" function for when you're using an external tuner. It puts out a carrier at low power. Does the 891 have a similar function or do you have to do this manually?
@@gabes80 No, you have to do it manually on the 891 unless of course you have a compatible tuner. with a compatible tuner and cable I simply press the tune button and le the magic happen :)
@@VE3BF ah bummer!
Thanks for the vid and effort. :)
I tried this with a cheapo 1/8th jack connector line and it didn’t work. Do I actually need the red/black Yaesu one?
Disconnected the alc link cable and got it to work easy by keying the mic. Also Tuner select is on External, no need for “Lamp”
the Yeasu cable wired different the a standard audio cable. you can find the wiring diagram on the web and solder a cable yourself. Just remember to mark each end, one for tuner and one for radio, the cable does not work in reverse. When done correctly there is no need to drop the power for tuning or keying the mic, the tuner will do all of that automatically.

@@VE3BF thanks for the reply. So the Yaesu style cable is necessary, got it. Now I ask, do you think it’s better to have the alc cable than just holding the tune button and keying the mic? Is the only benifit to the cable having the power drop without going through the motions myself? Or is they another benefit. Holding the tuner button and keying AM is pretty simple.
What possible reason exists to use a non-standard 3.5mm TRS wiring connection? Is this on Yaesu or LDG?
2:58 8 AA cells is 12 volts.
8 double A's is 12v not 9v. Also mine came with a double a battery holder already installed inside for 8 AA batteries which again is 12v.
Great demonstration!! Very helpful!!
Very good info on the Tuner and the radio I'm getting my FT-891 tomorrow. I think I can run it without looking at the manual with your great instructions on your videos. I probably get the Z-100 if I get a different antenna that needs a tuner. Sounds like the LDG Balun is a great add-on. I have the Wolf River Coils SB1000 with the mega tripod stand and an Rigexpert AA-55 Zoom to check resonance.
Sounds like like you are all set. Enjoy your new FT-891
Thank you Denis, I'm looking to get a FT-891 and antenna tuner. It seems to be very easy to setup & use. 73 de VA2LRA
Possible hookup iCom ic-703 ?
There is an Icom cable available for this tuner and it does work with the 7100 for sure
do the black and red cables come with the tuner?
SYED NASIRIN BIN SYED ZAINOL ABIDIN - no the interface cable is sold separately
Thanks for the informative review. I think the Z-100Plus will be just right for my 891. I operate portable with a Bushcomm Highlander 8 vertical on an Alpha Delta Outpost ground-coupled tripod mount.
What did you ground your equipment to ? Thanks KD2WPA
Thanks for the great review. Any problem not having radio interface with Index Lab I use? Colin
good video!!!!
Sir, can we pump more than 125 watts into this tuner while it is in BYPASS mode?
Good question, I don't know for sure but my gut feeling says no. 100 watts maximum. You might want to ask the folks at LDG to be sure.
I still have that tuner, but it takes close to 20-30 seconds for it to tune. Have a new rig and resonant antennas, so I don't use the tuner anymore.
