Cope, these do not meet current TASO standards so they cannot be used. I was just suggesting the guys in other states without such stringent requirements use them because they are very good and very inexpensive. If one goes out, heck, they are cheap enough to have several spares. They operate up to 5W with the stock battery and up to 7.5W (I think) with the larger batteries. You can set these in low power and get a stub antenna for more attenuation even since the crew is in such close proximity. In other words, there is more than enough power, way more, on high.
As always, you have to be careful what you say. Speak as though the entire world is listening.
