Its a very solid unit, a true transverter, 50w out continuous with 90-= 100w intermittent duty with increased PA voltage and a receive section that= is like no other.=C2=A0 The roofing filters make a huge difference and it = has made the difference between hearing someone and not on many occasions.<= br>
I highly recommend if you have some= disposable cash...
