I totally agree ... there is nothing clear about that path at all. 5 db
is a HUGE difference if you're anywhere near the noise level on the
other end, and it is a major difference if you're competing against
other weak stations for a contact. Under the right circumstances even 2
db can make a significant difference. I urge anyone who doesn't believe
me to check out:

QRP is fun and I've done a lot of it myself, but saying that 5 to 7 db
is not worth having in general is just nonsense.

I hate to be a contrarian, but the path is not quite so clear. That 5
to 7 dB can be the difference between making a contact or not making a
contact, especially on the low bands. We're not always talking about
the difference between S9, plus 20 or 25, but the difference between
S0 or S.5, or being an S unit above the noise.
I currently don't have anything bigger than my KPA500 and I'm very
happy with it, but anyone who says that 600 watts is always enough
power doesn't try to work tough DX on 80 or 160m. A serious 160 op
will tell you that 600 watts is often about 6 dB too little, sometimes
more...

I agree, the path is clear -- it is obvious --- sell the Commander as
5 to 7 dB is not worth having extra stuff around to fool with. As
said by a person with a growing interest and desire for QRP contacts.

If you are 20db over S9 with the KPA500, you can be 25 to 27db over
S9 with the Commander in line. The path is clear...
