I'm thinking about getting a P3. My K3 has the N8LP IF Output mod. Should I
undo the N8LP mod and do the Elecraft IF Output Buffer Gain Mod? Those SMT
resistors aren't getting any bigger as I get older. I do have a good
lighted magnifying lens and the tools required to do the SMD changes

Probably not necessary. I've had K3s with both mods and had no issues with
either one.

Hi,
Via means by way of as in via airmail. In this case we route from one
side of the board to the other (or from one layer to another) via a
feedthrough as they used to be called. In this day of shortforms and
acronyms they are universally simply called via's.

So I see how to attach it but have no idea what a via is? I built a KX
1 without ever running into a via I think. And if you can see the via
used to anchor one lead of the resistor in the photograph that is in the
instructions you have either better eyes or a better imagination than I do.
Hi Dave,
A via is a small hole in the circuit board used to connect traces
from the top side of the board to the bottom. There's a small hollow
metal insert in them that connects the two sides of the board (called
plated through vias) They're usually smaller than a typical
component

Before the recent change in the IF sample circuit, the transfer gain was
around -15 to -17 dB. In other words, a signal input to the antenna will
appear at the IF sample port about 15 dB below the input level. This
assumes the K3's preamplifier is off and, of course, that the K3 is
tuned to

Tomorrow I am going to make this mod on the K3 of a friend. To try to
see what difference it makes, I though I'd look at the IF signal on a
scope before and after. I have looked at the output on a modified K3
(mine) and it looks like about 2.5 mV (P-P).
Does that look about the
