Actually it's a bit over $1000 or there abouts.
The difference between 5W and 10 Watts should be almost insignificant
(IE 3 db) in use.

Actually all I need is to fix the orange/yellow plastic window over
the display. Some where in the past (before I purchased the Deb) I'd
guess some one used the wrong stuff to try and clean the window.
Combined with age that has rendered the plastic window almost opaque.
I wonder if the stuff they use to fix scratched plastic glasses would
work on that? Trying would certainly be cheaper than purchasing
another radio or even front panel. The KY197s are going for as much
on E-bay (yellow tagged) as a new KY97.

Why would having twice as much power not be significant?

at low altitudes, wouldn't line-of-sight be more significant?

You'd think so, but 3 db isn't much and would be barely noticable up
to the service ceiling that we can fly unpressurized. 5W would
provided a good signal all the way to the horizon.

Theoretical range of a 5 watt transmitter and 1 microvolt receiver using
quarter-wave whip antennas on both ends of the link is about 3000 miles. 10
watt range is about 4300 miles.

Radio horizon (the point past at which VHF isn't going to be heard) at
20,000 MSL over perfectly flat ocean is about 280 miles. 5 watts and 10
watts will be heard roughly identical at horizon.

Jim,

I was going to ask where we'd find that "perfectly flat" ocean, but thought
better of it. g

I was once told that the KY97A is actually an ICOM IC-A200 that is
OEM'ed for King with a different faceplate and knobs but the exact
same innards. Is this true? Those two radios sure look a lot alike.

The KY197A is one of their "Silver Crown" series radios and supposedly
a totally different design inside.
