I’ve just learned from Vibroplex that they are now shipping a new, upgraded version of the mAT-Tuner designed specifically to pair with the Icom IC-705 transceiver.
This model is called the mAT-705Plus.
You might recall from previous posts that I found the original mAT-705 to be an excellent ATU for finding matches, but later discovered it had a number of design shortcomings that prevented me from recommending it. The main issues with the original mAT-705 had to do with how quickly it consumed 9V batteries if the power switch was left in the “on” position, and then how complicated it was replacing batteries.
The mAT-705Plus seems to address these concerns by now employing 1000 mAh internal lithium cells that can be charged via a USB power source. It appears they’ve done away with the mechanical power switch altogether and the unit now manages power automatically which, to me, is a much better design approach.
Mat-Tuner reached out last week and are sending me an mAT-705Plus to evaluate. I look forward to putting it through the paces and see if this upgraded ATU is worth considering.
