Works great
Dave W•February 11, 2017
Using for MARS ALE. Competitive price with other dealers.
I did have to increase the re-tune return ratio to 1.9/1 since the antenna I am using is not a good match for some of the frequencies that I use with ALE. ALE requires 2 second tuning. As long as it doesn't re-tune, It works great.
I also use it with Winlink Express (and my ICOM radio).
It is also nice to know that my Smile purchases also help the Amateur Radio Safety Foundation. The Winlink folks.

Did not function as I thought. I think it was mostly error. I had an older one a couple of years ago, and that one worked great.

Fantastic companion to Icom Radios that do not have built in tuners but are plumbed for one. I've added one to an IC-718 and an IC-7100 with the appropriate cable (Sold separately) that activates the tuner button on these radios and controls this tuner. This is a fantastic upgrade from my MFJ manual tuner. Love this tuner, great price and great performance for 100 watts. The dual antenna input is a nice feature too.
