Great Product
|
Time owned: 6 to 12 months

I had the urgent need for a rotator controller when my Emotator controller suffered a sudden mechanical failure several months ago.
I corresponded with Jeff of Green Heron whose response times and customer service were second to none.
As the RT-20 appeared suitable, I ordered one. It arrived within a few days and with help from Jeff regarding the wiring (this was the first Emotator of this model he knew about) I quickly had it up and running.
I am very happy with the RT-20 and would recommend it to anyone who needs a replacement rotator controller.

I can only parrot what the others have said. A well made product with excellent service from Jeff. I made some inquiries prior to ordering. Each was promptly answered by Jeff with either a return email or a phone call. I ordered the "D" model. It arrived in one business day, configured to my Yaesu rotor. Setup was easy although I did have a few questions. Again each was answered with a return email, often coming in less than 15 minutes. A fantastic looking product as well!

I purchased an RT-21 from an estate on EBAY last year and had to call Jeff W2FU for help getting it reprogrammed for my T2X. I just changed to an ALFA SPID and couldn't get it to rotate CW. I called Jeff again and he had me do some test with it and found that it had a bad DC relay. I sent the board to him and he repaired it and shipped it back to me in Alaska by Pri. Mail and did it all for FREE. He is a GREAT HAM and builds a GREAT controller. Mike KL2RD

Amazing Controller
|
Time owned: more than 12 months
|
I purchased the controller at Dayton 2010 and use it currently with a Yaesu G2800 rotator,it's been 1 year.
Not only is the RT-20 universal, but has features never seen before,usb interface and included software ,which, acts as a server and a controller (yes I have turned my antenna from China), slows the motor down to a crawl as it ramps up and again as it reaches its heading ,as a result ,since using this controller I have never had a loose bolt in the rotor. Accuracy is absolute and excellent internal construction plus a very heavy duty internal power transformer complement the RT-20 . Unfortunately I can only give this product a rating of 5 :)

I just have to agree with all the positive comments. One of the great features is the ability to calibrate the box and rotor for the M2 rotor with the set up software available on the Green Heron Engineering site. I had a problem at first because I din't look at the site first before I started trying to manually calibrate the unit and got an error message. Jeff took his time the day before leaving for Dayton to call and help me out. Now it is working great. Why can't everything be like this!

Is there anything better?
|
Time owned: more than 12 months

From the use, to build quality, to support, I can't imagine having but something better. USB, point and shoot knob, easy field changes on menu...
I had my M2 Orion let my mast slip over 120 degrees, no problem for the GH, changed the heading and start/stop points and kept on going until I could climb the tower.
The box works excellent with Writelog, N1MM, DX Lab Suites, and my fingers.
Jeff has amazing customer support. I recently dealt with a lot of vendors in order to put together my new station. Jeff was one of the few guys that really wanted to take care of me, the customer.
I really feel good knowing I can use this box with so many different rotators.

Outstanding Service and Performance

I've been remiss in doing a review of this fine controller. I purchased it 3/15/2006. Jeff had it all set for my Yaesu 2800. I bought it mainly for the ramp up and down feature. I have an aluminum tower with a 4el SteppIR (6-40). With the 7# weight on the end of the boom to counter balance the 40mtr element, there was quite a bit of twisting at starting and stopping. Well there isn't anymore. Its so smooth people can't believe it.
Thanks Jeff keep up the great work.

Very good

I am using the RT21D (black deluxe version) for over two years now.
I have 4 of them and they are used to turn the 4 Prosistel rotators.
The box is flexible, has a nice big display, and a good working preset turning knob.
You can easily reprogram it for other rotators. The menu’s are easy to operate.
The contest program N1MM supports this box. This makes it possible to point and shoot to the dx station you want to work with a simple key stroke. (Alt J).
Also the benefit that you can operate the box over the network with the free software that is delivered with the box makes the system very flexible.
The WSJT software from K1JT can be connected with the Green Heron tracking program which is free.
This make tracking the moon and satellites easy.
The box is made to operate with all the modern rotators that are on the market today.
The support from Jeff W2FU is outstanding.

Excellent Product and Service
|

Remarks: I've owned and operated a RT-21 for 2 years with an Orion 2800DC rotator. Operation has been flawless. The setup utility is excellent as is rotator control via the DXLabs suite. Last Fall my tower suffered a direct lightning strike. My RT-21 together with other equipment in the shack was damaged. I sent the RT-21 to GH for repair. A friend and I tested the repaired unit in my shop for 30 minutes or so and confirmed operation with my repaired Orion 2800DC rotator, which also had been heavily damaged and required reed and limit switch replacements as well as bypass caps. However, control of the repaired rotator, after installation in tower, with the repaired RT-21 was erratic until there was no control at all. I confirmed the integrity of my control line then wrote Jeff Green. He was kind enough to take time to help me test and identify issues by phone and email. Eventually he told me to send the RT-21 back again. This second time around Jeff again replaced boards, updated firmware and tested the unit on an Orion rotator to confirm operation. He spent more phone and email time with me after the second repair did not resolve my control issue. Finally Jeff said the problem must be the rotator. I purchased and installed a new Orion rotator, after a second rotator rebuild failed. The RT-21 now operates as advertised. I sent my old rotator to M Squared for rebuild and will keep it as a backup. The interior of my old rotator was heavy carbonized from the lightning. I likely missed a carbon trail that created stray voltages in the rotator or perhaps suffered motor damage. I don’t know.
I'm guessing Jeff spent the better part of 4 hours on the phone with me, including time after normal business hours and on a weekend, trying to get me going. I was charged $66.64, including shipping, for the first repair. Jeff refused my request for an invoice for the second repair even after I confirmed my problem resolved with a new rotator and the second repair was un-necessary.
The bottom line is this is a great product that comes with excellent service if you need it.
