How to use
The front panel switch is used to select the mode. When it is in the TUNE position, the standing wave indicator circuit is accessed. When the transmitter is transmitting, the brighter the LED, the higher the standing wave. Two capacitor controls are used to adjust the matching. The rear switch sets the antenna impedance.
Note: Standing wave indicator LED.
Note: It is essential to check the standing wave before transmitting, otherwise the ORP transmitter without high standing wave protection may burn out.
Note: If quick tuning is not possible, use a network analyser for debugging. At this stage the mode switch should be set to WORK.
Note: This tuner is for ORP only. Excessive power can cause components to burn out.

While this tuner feels solid and looks well-made, using it was more frustrating than I expected. The tuning process isn't intuitive, and despite multiple attempts, I struggled to get reliable matches on the advertised bands—especially 10m and 40m. My tuning success felt more driven by my mathematics in the initial antenna layout, rather than what the tuner could accomplish. CW output was, accordingly to the LED light, successfully tuned but SSB was hit or miss. I appreciate the compact metal design and BNC connectors (for CRP), but that doesn’t make up for inconsistent performance. I’m also skeptical of the build quality inside, as others have noted soldering issues, which might explain the erratic tuning. Overall, it’s a nice idea, but not one I’d recommend without serious reservations. A good, used automatic tuner might do you better than this.

Surprised how easy this was to use with my QRP rigs. So far I've had no problem tuning up multiple home brewed wire antennas as well as verticals I've built using this little tuner. I've double checked the SWR using an SWR Meter to check the SWR when using the little LED on the tuner and it's basically spot on showing very low SWR on reasonable antennas.

I'm just using it on a receive antenna, so can't speak to SWR. It does seem to work over the advertised frequency range. For some reason the the capacitors are rather stiff. Perhaps they will loosten up with use.

This tuner was recommended by other ham friends for QRP work. They claim it works great & at a good price.

I use this with various QRP labs QRP rigs including QMX and QMX+. It works great seems to tune any where from 80 thru 10 meters. The little led swr tuning indicator works perflectly. I only run 5 watts max thru it, it is for QRP only . When you take this to a pota activation you don't need a separate swr bridge. It's a compact quality product. Just don't put over 5 watts into it!!

They ran out of solder at the factory. I went to tune an antenna I knew was 1:1 on 40, and had to turn the right knob to its extreme to get any kind of dip in the light. I went back and read all of the reviews on here - and did I have the courage to open the lid and see if I too - like several others - had missing solder in the toroid pcb holes. Sure as shinoa - no solder, and barely any solder there. I think they have a box of these that a kid made in the factory who was like, "Nahhh, I don't want to put my solder gun tip all the way in there" and they're hoping we sort thru the units for them. It's a shame because this is a nice unit - super small. Just for those few joints - it's okay. I hope the seller sends me a new tested unit - and I'll change my review.

I bought this thing just for kicks, but it's actually turning out to work quite well. I checked the Z Match's tuning with a traditional SWR Bridge, and it's within safe limits (usually 1.5:1 or better). Not sure on this, but looks like the LED gets it's power from the RF from the radio, so no batteries needed. This was just what I need for going out camping or kayaking, etc. and taking ham radio with me. The radio I used to test it is a uSDX HF Transciever I bought on Amazon a few months back for about fifty dollars. One thing about the Z Match Tuner ... be SURE you don't exceed 5 watts for tuning, 10 watts for operating. You'll likely burn out the innards of the tuner if you do. I looked inside. It's made of some very lower amperage rated components and is intended for QRP (under 10 watts) operation. If you use it as intended, should work quite well. Just don't try to tune your 200 watt Yaesu or Icom with it unless you turn the transmit power below 10 watts.

Das Gerät macht, was es soll. Die Größe der Knöpfe macht die Bedienung aber unbequem, wenn man öfter nach regelt. Die Verarbeitung ist exzellent. Die Bauteile sind Recht großzügig dimensioniert. Aber da die Bedienung im Vordergrund steht, nur drei Sterne.

Cheap and simple to use. 5 watts QRP only. I literally ran 50 feet of speaker wire along my fence (4 feet high) and I can tune 20m and 40m (NVIS) no problem. LOVE IT. PS I do have a proper EFHW antenna, but don't have the space for it at home.

Took a risk on this despite mixed reviews. I used a nanoVNA to tune my antenna with this manuel tuner before connecting to my (tr)uSDX transceiver. Tuned my end fed halfway easily down to a 1.2 SWR. Made contacts into several states with 5 watts USB on 20 meters. I did have to place it into the WORK mode when tuning with nanoVNA, then use then LOW IMPEDENCE setting to get the best tuning. It's a keeper!
