Great tuner BUT  Time owned: more than 12 months
As my summary states this is a great tuner. However I got off to a rocky start with Palstar. I was told it was in stock ready to ship when I called them on the telephone to inquiry about it. I was told it would be here within 2-3 days from Ohio to IL. After a week/noshow I again called Palstar and was told at this time they were just putting the finishing touches on my tuner and it would be shipped later that day. It did arrive in a couple of days and the metering was total out of whack. RF output readings on both scales were W-A-Y high. In addition the meter would not zero and it appeared a small object had gotten into the movement preventing it from going to 0. I called Palstar and talked to Paul and he stated he had never seen this before but was more than happy to make it right. He shipped me a new meter and I agreed to install it myself. After replacing the meter and calibrating it with a Bird Model 43 everything was correct. IMHO this tuner was pushed out the door with little or no testing and calibration. It really put a damper on my buying from Palstar but after a couple of years the tuner has more than lived up to its good name. I run legal limit on 160-15 (AL 1500) each day and run ladder line on 75-40m with this tuner and never once has it protested. Again IMHO for the price & class of this tuner I expected better quality control. To Paul's credit he did offer to issue a call tag and pick the tuner up, return it to him and he would do the work.

Well Built and BIG!  Time owned: 0 to 3 months
I purchased the AT4k becasue I wanted a tuner that would handle larger power requirements for future amplifier upgrades and still provide maximum tuning efficency. I use the Palstar with a G5RV cut for 10 to 80. My previous tuner was an MFJ 989D. I returned that tuner becasue the metering was grossly inaccurate and opted instead to try this Palstar. Well there is no discernible difference between the 989d and the Palstar in terms of tuning ability but there is a big difference in construction. This unit is built very well. The Inductor really does have the feel of a VFO albeit a bit stiff. There was also a nice little bag of extras that included an extra bulb should the original burn out, some cotton swabs?? and some extra screws althouth no mention was made of these in the instruction manual. The tuning chart does NOT include settings for the WARC bands but I have had not trouble tuninging those bands. Have not tried 10 meters yet. The metering was VERY accurate. The unit does NOT include a dummy load so one must be purchased seperately and hooked to the BYPASS output. If you really want nice construction this is the unit to get but beware it is BIG. I gave it a five for construction but I would not expect it to tune a wet noodle. I would say it does an average job in this department but this could be because of the particulars of my antenna installation. I have NOT tried the unit with high power yet but from the looks of the construction it should have no problems with it. I think if it were possible to give it a 4.5 I would becasue of the average tuning ability. If you really want to invest in quality construction you will not be disappointed.

Super Tuner  Time owned: more than 12 months
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
Iíve 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!  Time owned: 0 to 3 months
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 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.

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.
