I do not know the significance of the difference in altitude specification
between the two units. The manual clearly states that the maximum altitude
for the 175 watt unit is 15,000 feet.

What's confusing is the manual (dated Aug 15, 2001) for my 175 watt
Becker unit states it's good to 35,000 feet. Specifically:

"Operating altitude 35000 ft. in accordance with EUROCAE/RTCA
ED-14D/DO-160D Cat. C1"

This is a unit purchased in Aug 2001. The manual just downloaded from
the Becker-USA site (dated Jan 15, 2002) shows the 15,000' altitude.

Time to call Becker, I think.
