The VX-150 is not the smallest, lightest, most powerful or even prettiest radio on the market; but it has to be one of the most rugged. My VX-150 is about 4 years old and has been dropped, rained on, thrown in the car and buried in a rucksack. It still keeps going. I think that it was one the best purchases I ever made and is excellent value for money.

Vertex

$117.95 (Comes with two batteries.)

I have had a problem with the ear piece/PTT connector on the side of my radio after four or five years. I had to tape the "adapter" to the side of the radio to keep it going. I've since given this radio to my wife to replace the VX-5R, and ordered a new VX 150.

I very strongly suggest ordering the special version of the Motocomm PTT/system from Flytec USA, which comes with the special small button and no need for an adapter. The model for the Vertex 150 is actually close to MC- 558 (I believe). Steve Kroop at Flytec USA can help you get the right model that was developed specifically for hang gliding.

I also have a couple of higher capacity batteries that require an external universal charger. This charger is such a hassle that I rarely use it any more and just use the 700 mah batteries (FNB 68) that come standard. They seem to last plenty long enough.
