Yay! Make it bolt to the underside of the KX3 with a cavity for a
skookum battery of our choice and you've got an instant winner for
tactical SSB. An effective ATU would need to be part of the design;
something that would tune a modest-size whip.

I still maintain that 10W - even with speech compression - is not enough
for SSB. Part of the problem is that many 'home base' stations suffer
from high manmade noise levels. Operating portable in the bush with a
hot receiver it may seem like they should be able to copy us because
their 100W signal is S9, but if their noise is S8 and the bush radio is
only 10W ...

Practical tests communicating between bush camp and home consistently
proved that 10W CW was clear copy every night, but SSB was hit and miss.
25 watts would have made all the difference. I would have been totally
happy with cw, except the other hams in my family are morse-challenged.

My QTH has many disadvantages (noise, low antenna, wrong part of the  
country, etc.). But I still make lots of contacts at 10 W.

I think we have to draw a distinction between "guaranteed"  
communications and "adequate, sometimes edgy" communications. The KX3  
represents a compromise between portability and output power, putting  
it into the latter category.

Yes, you may have to move to slightly higher ground or call three  
times rather than once, but IMHO this is part of the fun.
