This is the same Mountain Topper MTR3b that you know and love but with new added features!!
Developed by Steve Weber KD1JV Designs, the PCBs and enclosures have all been produced proudly here in the USA. Each unit is fully assembled by hand here at LNR Precision. Steve Weber has also been very involved in the testing of this phenomenal radio to ensure the quality will be what you expect in his units. Please note that the Mountain Topper does not have the European CE mark, thus European customers that this affects should not purchase if this is an issue for you. At this time, we will not be offering this as a modified kit as we did for the original Mtr3b.
