[Elecraft] K3 Buffer Mod

[Don Rasmussen]

Bill, just to clarify:

- I assume you can handle the SMT without any trouble
or worries.

- I also assume that you have a good reason to want
the extra 17.7db, so go mod, be happy. 

But for anyone else that may not be comfortable with
SMT changes, I am suggesting that before they partake
in that, they understand what the mod does and how
it would help them in their application.

My suggestion is, that for someone that's using the
standard LP-PAN + Power-SDR + E-MU 0202 setup, there
is no benefit to doing the mod, as the Y coordinates
in PowerSDR are adjustable (as discussed on the Yahoo
LP-PAN list). 

Works good - lasts a long time. ;-)

That's my story and I'm sticking to it. 

Respectfully,
Don

-- And sorry Tony I think you were more interested in
the discrete vs. SMT packages but I wanted to clarify
on this point – think you got your answer. !!!

17.7 dB transfer loss from RF IN to IF OUT is why...
