Awesome!  Time owned: months
Love it! I replašed my Yaesu G-1000DXA control box for the RT-21. Very simple to set up, a joy to operate. The customer support service is outstanding, answered all my questions over the fone and e mail.

Excellent product and support  Time owned: more than 12 months
I have several of these boxes and I love them.
They do wat you want. Turn your yagi without problems. I have them for quite a few years and use them with several types of rotators.
Highly recommended.

RT-21A Deluxe Edition with WiFi interface  Time owned: 3 to 6 months
I bought this controller at the Dayton Hamvention 2016. I decided to buy the deluxe version that include a nice fluorescent display style. I also bought the WiFi interface board.

1- The technical support is totally awsome... they even modified their firmware to address a special request I made to them.

2- The Wifi interface is great.... I using it from a web browser windows.... looks like if it is an application, even from a web browser! The support and the use of the controller from a web window is really well designed.

3- The quality is totally awsome... great features to customize the use of the rotor motor. They used a standard and well supported USB chipset. Easily installed on a Windows PC and even on a Macbook Pro using MacOS.

I highly recommend this product if you want a controller well designed with great technical support.

The RT-21 is the best  Time owned: more than 12 months
I own two of them. There is nothing this controller can't turn. It handles all of the requirements and features the various rotators require. You think of it, and I bet the RT-21 controller can do it. Limit travel, over travel, brake delay, reverse delay, and my absolute favorite option: ramp up and ramp down speed. You can start and stop a big HF yagi with no element "wagging". Customer service is the best, and owner, Jeff is back with reply to an email in usually minutes. It's a digital controller with an analog feel. Works for me!

Great Service  Time owned: 0 to 3 months
Just paired the RT21 to a new PST 61D. Very well designed product. Operator induced, failure to read completely, resulted in an email to Jeff on the 4th of July weekend. Got an answer a few hours later. Wow, great service. BTW this controller has so far surpassed my expectations based on prior BigBoy control box experiences.

Excellent product and support  Time owned: more than 12 months
GH has developed a superior product and stands by their products. I have two RT-21s and both work flawlessly. One operates a PST-61D rotor on a mountaintop in NY and the other controls a HAM-IV in MD. I accidentally mis-wired the HAM-IV after a shack renovation causing a transorb and fuse to blow. Jeff repaired under warranty. You can't ask any more of a manufacturer. GH certainly stands by their equipment.

The Best!  Time owned: 0 to 3 months
This is an excellent product. High quality parts, IPC class workmanship and a complete instruction manual. I bought it used and had to reconfigure it. I was able to reconfigure the RT21 back to the HAMx model without incident or failure. I also appreciated Jeff's reassurance in the email as well as directions in the manual. The drawing of the PC board was especially helpful since not all of the connectors are easily read on the board especially for those of us who are not young anymore.
I am already looking for a 2nd one for my other tower.

Excellent product  Time owned: 0 to 3 months
I recently purchased a RT-21pp for a prop pitch project I have been working on. I have tried to utilize a M2 controller and it simply was not up to the task. I ordered the RT-21pp and could not be happier. Their customer service is wonderful and all questions were ordered promptly. My order arrived very well packaged. Instructions are very well written and thorough. Fit/finish/quality are evident. This controller should last a very very long time. If you are looking to purchase a very capable rotor controller that will amaze you at how it works this is the one for you. Purchase one today you will not regret it!

Excellent Controller  Time owned: more than 12 months
I've been using a Green Heron RT-21 controller in my station for the past 5 years, along with an Orion 2800 Rotator. The pair controls and turns a very large array on top of a 72 foot tower. I haven't had any problems whatsoever with the RT-21.

The instructions provided by Green Heron for the controller are adequate. I did not experience any problems setting up the controller to work with the 2800. I had a Prosistel rotor before, and setting it up with that rotor was fairly easy as well.

I use HRD 6.2 for logging and automated control. The RT-21 easily interfaced with HRD Rotator control. I noticed after a recent strong wind storm, my array had slipped a few degrees out of compass alignment. Using the adjustable settings in the controller, I was able to realign the physical position of my antenna array back into alignment, without resorting to any mechanical adjustment to the antenna system. That's a great feature to have that ability.

Overall, I have been extremely happy with the RT-21. It simply works very well. To be overly critical, there is only one thing that could be improved. The unit does produce a minor bit of noticeable hum, caused by transformer vibration from the built in power supply. The hum is only noticeable when the room is quiet. However, once the rigs and other devices in the shack are turned on, the bit of hum from the RT-21 is entirely muted by the other customary noises in the shack.

The RT-21 is a great product that I can highly recommend.
