That's exactly what I did, on the advice of the below quoted author, and
it is very effective. Admittedly, my hearing is probably worse than
many, and I'd gladly take a few more dB of equalization, but what the K3
provides is free [not counting the cost of the K3 :-)] and it does work.
Just go slowly when working with it. I was pretty much giving up on
it until Jim counseled me, "One change at a time, try it out under
varying conditions." I keep a station journal [separate from my log]
with notes and things, I used it to record my subjective results and the
settings I made.
I don't think an external equalizer is any easier to adjust than the K3
internal one, it just may give you more gain. At some point, more gain
becomes a non-starter, my Heil headphones or the speaker start to overload.

The RXEQ built into the K3 is capable of about 36 dB of combined high
frequency boost and low frequency cut. This won't be enough to
compensate for really severe hearing loss, but it can an effective
solution for the majority of folks. As a starting point, set the four
lowest bands to maximum cut, leave the fifth band at zero, and the
remaining bands gradually increasing in boost until it sounds good to
you. Those with more serious loss will usually want boost be greater on
those higher bands. The most important octave for speech is 2 kHz, 1 kHz
is next, then 4 kHz. So with severe hearing loss, you will generally
want the top three bands up full.
I would do this before I would consider an external equalizer.
