It's a KEEPER!!  Time owned: more than 12 months
Got it second-hand a few years ago. Have been using it with my Ameritron AL-1200 on 40-10m at 1200w PEP SSB, 1200w CW and 800w RTTY with NO PROBLEMS AT ALL!! Haven't used it on 80m. Antenna SWR's have ranged from 1.5:1 to 4:1. I hope all the other ones are as good!

Very impressed  Time owned: 0 to 3 months
I've only owned this Tuner a couple of days. Obviously, it's older and used. This is first gen and was produced 2003-2008. After that, there was the PRO and the PROII model. Other than the newer models "AUTO" tuning when transmitting and seeing a high VSWR, the original model you have to press the tune button; and the original model only have 200 memories vs thousands, they are very similar.

When I first fired it up, I was glad to see it had the 2.5 firmware version in it. The older version didn't have the 200 memories. Just the one it was currently tuned to.

I normally use a FAN Dipole for my antenna rig. Elements cut for 80, 40, and 20 meters. But many times, especially in the summer months, there's a lot more activity on the 17, 15, 12, and 10 meters. My existing/previous tuners were an MFJ with roller tuning and a B&W with notch tuning. Both tuners are excellent, but bouncing around frequencies became a pain to retune all the time. Even with writing down all the presets. So, I wanted to try and auto-tuner. But at the same time, I didn't want to spend $550+. And being I have a 500 watt amplifier, tuners could get expensive.

I took my chance on an AT-1000 first generation on ebay. From a reliable seller; including a 14 day return policy. Got this tuner, including shipping, for $150. So, as long as it worked reasonably, I would be happy spending the money.

I memorized the instructions prior to connecting it. So far, I've been able to tune it on the LOW, MIDDLE, and HIGH frequency range of each band. 80, 40, 20, 17, 15, 12, and 10 meters. With just the 3 band fan dipole antenna, the highest VSWR I've had, still doesn't pass the 1.5:1 range.

Obviously, a resonant antenna is better than a non-resonant and a tuner. But for my property and space, it's not very practical to have that many antennas or that much space. Plus, most of the negatives of antenna tuners and information about SWR, is exaggerated and inaccurate.

So far, this is a very good tuner. Once frequencies and bands have been tuned and stored in memory, "Retuning" only takes about 1-2 seconds. Initial tuning only takes about 5-6 seconds. I'm very pleased with the AT-1000. Radio is happy to see a good impedance match. Other sites say I've got a good signal. And unlike the manual tuner, I'm able to bounce around bands and frequencies much faster and enjoy the hobby better. Definitely worth the $150 for a 1st Gen AT-1000 vs $500+ for the 3rd gen.

Solid and dependable  Time owned: more than 12 months
I've owned this tuner for several years and have found it to be an exceptionally strong performer. It finds an almost perfect match in seconds and doesn't exhibit any of the re-tune issues I have read elsewhere. Takes hundreds and hundreds of watts without breaking a sweat. Tuning is rather noisy, but it isn't a big deal. Watching the SWR drop flat to a 1:1 match will make the sound of the relays music to your ears. :) 73 and God Bless.

Excellent Experience  Time owned: more than 12 months
I bought the at-1000 used two years ago to go with my IC-7600 and FL-7000 linear. It has worked flawlessly for me. I have not experienced any of the auto-retune that others have complained about. On 20 meter SSB I tune it for around 14.235 and it is good from 14.150 to 14.310 without having to re-tune. It is noisy but unless you are using a new antenna it takes less than 5 seconds to get you where you want to go. I am using it on several antennas and it handles the Z on my G5RV without a sweat. The linear loves it!

LDG makes great equipment. The only reason I would get rid of this is to upgrade to the AT-1000 pro ii.

Very satisfied  Time owned: more than 12 months
I am leaving this opinion since I realized that hams should also leave some good reports. I have only operated mine at a maximum of about 350 watts output. I have owned it for so long I have lost track of time. I just hope they stay in business a long time serving the ham community. It has even enabled me to tune to poor antennas when the good one blew away. I would hope they design an at the antenna remote antenna tuner. Sorry no negatives. It has given years of flawless service. Even when the real SWR was out of this world.

Very Nice Tuner...  Time owned: more than 12 months
I have had this tuner for 5 years... Worked flawlessly for 99.999% of that time. I sent it into LDG for repair, they fixed it, (The SWR board had an issue), and charged me nothing! Tuner is back, and I just bought the newer AT-1000 PRO II as a result of the customer service...

Workhorse  Time owned: more than 12 months
I´ve had two of these, one I sold (my misstake) and the other one has been in service since 2008, flawlessly !

It easily swallows all the power and SWR I´ve thrown at it :-)

But, and this goes for ALL tuners automatic as well as manual, there is a limit how high SWR it can tune out,
it can only match the radio or amp to the impedance seen in the coax by the tuner.
It will NOT make your antenna any more efficient or change the antenna´s resonance / SWR.
Also, the groundpost at the back is there for a reason.
The tuner should be connected to RF-ground for the same reasons as you need to connect you radio and amp etc. to a good RF-ground.
There is a micro processor inside and it will go bananas if exposed to high RF levels in your shack.
That RF will also affect your PC, your radio and your transmitted audio.
Simple as that. No mystery.

The tuner will work as a champ if you read the manual and follow the instructions there :-)

Service Awesome  Time owned: more than 12 months
I have had this tuner since 2009, aand it has worked great. Recently, howevere, it stopped tuning and I returned it to LDG. They had it back within 4 weeks, and had replaced the logic board at no charge. Amazingly quick and now it works like new.

Works well  Time owned: 6 to 12 months
Simply works. No complaints. Haven't used a manual tuner to compare it to, but it tunes whatever homebrew wire antenna I connect to it with one touch of a button.

Used with IC-706MkIIg

Does the job!  Time owned: more than 12 months
I have it for over a year and it keeps on working flawlessly.

Is is a bit noisy, but that noise comes from the heavy-duty relays. I have been using other similar high power antenna tuners and they all make the same noise, so no problem with that.

It has a long tuning time (up to 8secs), especially if your antenna has an unknown Z. I have the Kenwood TS-850S with SGC-500 and it tunes from 160m up to 6m with 500W+ RTTY & 800W SSB...

So, well done LDG !!!
