Not only is this a terrific piece of gear but when I requested factory support Palstar took care of me first class! Wish more USA companies were this fine. You will be pleased all the way around.

The Last Tuner You Will Ever Have to Buy!
|
Time owned: more than 12 months
|
|
I’ve owned the AT4K now for well over a year. The only issues I have had was the death of the meter bulb. The lamp is easily available from Rat Shack so not a problem for replacement. The tuner has operated flawlessly with no spitting or arcing. Operating is straight-forward with no gotchas. Construction quality is some of the best I have seen in amateur radio. In fact, the quality is borderline Mil-Spec. Buy one of these and you will never use a MFJ Tuner again. I promise you on that.

True to their motto
|
Time owned: 3 to 6 months

This tuner is "Built like a Tank" AND I believe I could tune a wet noodle, with it. It tunes everything I have thrown at it. It is the most solid performer I have seen, so far, and Paul is right there, if you have any questions, happy to help, with his expertise.
Get this tuner, there is no better.

Very nice tuner!

I just recently (Aug 2007) purchased this tuner, and the first thing I did was open it and look to see if the quality is there, given its price. It definitely is. This thing is built very well, including the roller inductor. The metering is top shelf, and the circuit design itself is very unique.....allowing for balanced or unbalanced line matching by grounding or lifting from ground the bottom end of the inductor through the clever use of a relay. The T network design matches just about anything. I have not had the problems described in other reviews in matching antennas on 10 meters...it works well there, too.
Nice, BIG, quality unit...make sure you have the room at your operating position.

TOIP NOTCH UNIT
|
Time owned: more than 12 months
|
|
I have had my AT4K for over a year now. I find the controls smooth to operate. Both the transmitter and antenna capacitors. The roller inductor is also smooth to operate. The cross-needle SWR meter is easy to read and use in tune up. The AT4K also has a peak reading meter. This is usefull in reading SSB peak output. I had a Nye Viking MB-VA tuner prior to my AT4K. I could not tune across 160 meters on my inverted "L" antenna. I also had trouble tuning all of 40 meters on the same band. The AT4K is built like a tank. It weighs about 27 pounds and is larger than a DRAKE L7 AMPLIFIER. You will need to allow some space in your operating area for this tuner. If I were to trade mine off, it would be for the AT5K unit.

Inductor tie up !
|
Time owned: more than 12 months

Well I think perhaps I might have spoke too soon . The inductor is binding up on every turn. I haven't tore into it yet but one thing for sure , for over $800 there shouldn't be ANYTHING wrong ! More details to come ..........

A Top-Flite Tuner
|
Time owned: 0 to 3 months

This tuner started out with an edge-wound roller inductor that was held together with three tie-wraps. It evolved into an edge-wound inductor that did not require tie-wraps. I found the late model edgewound roller inductor to be a quality unit, but it did not turn as smoothly as I would have liked. I now have the latest model with the ceramic roller inductor that turns very smoothly. I am presently using the AT4K with a Carolina Windom 80 antenna. I was able to get a 50 ohm match on all bands 80 through 12 meters with an antenna analyzer. I could not get a match using this tuner with the Carolina Windom 80 on 10 meters. There was too much inductance still left at the end of the roller inductor. I do not know how this tuner will work on 160 meters, but it appears to have plenty of inductance for 160.
The tuner comes with a wall wart to energize the meter backlight, meter movement, and the balance-unbalance relay. If the tuner is fed with an unbalanced (coax) line, it can be used without the wall wart, but the meter movement and backlight will not work. The AT4K relay is grounded (unbalanced) in the unenergized position.
This is not the case with the AT5K which is balanced with the relay in the unenergized position. So if the AT5K is to feed an unbalanced (coax) line, it must have the wall wart voltage applied (and the red tuned output button in the out position which energizes the relay).
The ceramic roller inductor in this latest model of the AT4K is large and turns smoothly. Resettability is reliable and accurate. The wattmeter is accurate and the peak hold feature works well. The ceramic antenna switch is large and is of quality construction, and the input and output capacitors are large and well made. The input and output knobs are new with a gray numbered graticule instead of the gold colored graticule of earlier units. This unit easily accepts 1500 watts with no strain. I highly recommend this latest version of the AT4K. I have an AT5K, and this latest AT4K works just as well for me at 1500 watts. You won't go wrong with the latest model of the AT4K.

This tunner seems to have undergone several revisions.
I believe that some folks in the 2004 ~ 2005 era had a version of this tunner that had a less than stellar inductive coil that was supported with a series of tie wraps (???).
That is no longer the case. I feel bad for those that purchased this product from Palstar because it appears that they have reverted back to old style "heavy duty" coil.
The tunner is built like a tank. It is big, heavy and could be used as a weapon if one could lift it high enough to throw.
The dials are smooth and concentric. The coil and coil turn meter are of excellent quality and work great.
The meter is one of the best in the market.
I love this unit. I use it with my Ameritron AL-82 and it handles 1300 Watts with no issues on all bands.
No arcs, sparks or other sounds.
I recomend it to all, as long as you make sure that it is the NEW version.
