Basically Is OK, but not the best Tuner Out There
|
Time owned: more than 12 months
|
I bought mine NEW back in the 1970's and had it for several years.
At the time I ran Yaesu FT-101 & a Heath SB-220 though it, all bands, from 160 thru 10.
Early-on, after the warranty expired, those unique push button switches became "flakey" to operate and from then-on required me to be VERY careful when operating them, else the exposed rectangular button covers would pop out and land on the operating desk.
The horizonatally mounted coil developed a slight downward "sway back" shape because after awhile the SB-220's RF power overheated it and softened the clear plastic coil formers. (This gross overheating was cured by removing the grounded coil bracket that contacted the chassis, then I steel-wooled the bracket and chassis contact area, then bolted them back together again.)
I also ran balanced feedline antennas at that time, and discovered that the built-in balun was badly UN-balanced at it's "balanced" port for 10 thru 20 meters.
To help remedy that problem I had to replace it with a physically larger, and much superior "Super Balun" from Palomar that barely physically fit within the tuner's chassis.
So - with correcting the coil's grounded end making a better contact to the chassis, replacing the unit's inferior balun, and gingerly operating those flakey rectangular switched, I was able to continue to use that otherwise very nice tuner for several more years. ---John, K8JS

Heavy Duty
|
Time owned: 6 to 12 months
|
I picked this unit up used and paid a good price for it only to find out that it had been damaged by dropping, and worked on by someone that was pretty bad, to say the least.
I fixed it, and it is one of the best tuners I have had. Tunes almost anything very quickly. Hard to find, but worth the effort.

Excellent Tuner!
|
Time owned: more than 12 months

I have used at least six of the most popular tuners and this is by far the best. I even bought a second which I was talked into selling. Dumb, dumb. Really, of everything out there, you cannot do better, especially for the price.

High Quality, High Power Capability, Brute Force Tuner
|
Time owned: 6 to 12 months
|
|
I own 2 Dentron MT-3000A tuners and believe these are the best commercially tuners built. I have in my 35 years of building, operating and purchasing ham gear not seen another tuner like this one. I have owned numerous tuners and still have them but non of them compair to the MT-3000A.The MT-3000's are industrial strength tuners and are built out of very high quality components. I have run full power through these units to most any antenna resonant or not and never an arc over. If you want a tuner built like a Tank then I recommend the Dentron MT-3000A

Solid, reliable
|
Time owned: more than 12 months
|
I have owned one of these for over 5 years, using it with an Alpha 76CA, Drake L4-B, Johnson Thunderbolt, and a Heath SB-200. Even at the legal limit of power from the big Alpha "3-holer," the MT-3000-A performed smoothly and without arcing over a wide range of SWR and bands. I have never noticed any heating of internal components at all. All controls are heavy duty in feel, and work as expected. The internal construction appears to be well engineered, and the use of quality materials is evident. I wonder why Dentron went out of business, building equipment like this?
If you're buying your first used tuner, take the time to learn how a tuner is properly operated, then question the seller to determine whether the unit you are interested in was abused. The MT-3000-A is heavy enough to take a lot of inexperienced ham's abuse without damage, in my opinion. This is aparently not true with cheaper-built rigs like some of the MFJ "high power" models.

Probably the best switched inductor tuner
|
Time owned: more than 12 months
|
|
One was purchased used for use with a Force 12 C4SXL on 17 & 12 meters. Mechanically the unit appears to be well built. After a couple years of operation at the 1 KW power level there has not been any indication of sparking or overheating. The antenna switching abilities are very useful. Antenna 1 can bypass the tuner or use the tuner, Antennas 2 & 3 must use the tuner. The only problem (which appears to be commom) is the power pushbotton indicator fails, but the switch continues to operate fine. The next one I see at a reasonable price will be added to my station.

GOOD HEAVY DUTY TUNER
|
Time owned: 0 to 3 months
|
|
This is a really nice tuner. has alot of features dummy load, balun,nice metering, so far it has tuned anywhere on the bands i have tried and works with legal limit just fine. The only thing i see could use an improvement is the 2 amp fuse in the dummy load.it is soldered in place. if they had just put a 2 amp trip fuse you could reset, it would have been fantasic. It is a good tuner for around the 300.00 range.

Good Stuff

The only way to get serious about HF is to have one of these. Anything else is wannabees. Five star rating all the way. Easily takes over a kilowatt to the most ridiculous impedances known to man.

If you are looking for a nice desktop tuner. This puppy is a nice one. Full metering,200 watt dummy load, bal line, wire line. Dentron put good quality parts into there products and this is not a exception. Will handle 3K Peak. And it sure looks good on my desk between my 2 clippertons ( L and V)
