Jon,
Joe's response is correct, his almost always are ... if maybe a little
cryptic. You need the KXV3 or KXV3A transverter interface and the
KXBPF3 general coverage band pass filter. KXV3(A) provides an 8 MHz IF
output for things like a P3, and a separate receiver input. You
activate that with a tap on the RX ANT front panel button. I don't know
at which frequency the receive path is switched as you ask, but it is
definitely above 500 KHz.
My K3, with new synthesizer, receives fine a bit below 160 meters using
the ANT 1/ANT 2 connectors. It does NOT below 530 KHz, I have to use
the RX ANT on the KXV3.
I don't know between those frequencies, here in the New World, they are
filled with bloviators of all kinds, and I ignore them. You'll need to
look up "bloviator", I'm sure there's one or more equivalents in
Spanish, possibly many. :-)
This new range on the K3 is really cool!
73,
