The K3's IF OUT bandwidth is limited only by the front-end RF filters so
it covers an entire amateur band, plus. That is handy for a panadapter
because it is always centered on the VFO A frequency. The IF center
frequency is 8.215 MHz.

It's around 8.15 MHz. It's ahead of the ADC and 15 kHz 2nd IF, the RF
is over 200 kHz wide and is nominally there for connection to a P3.

IF means Intermediate Frequency. It is the result of mixing the RF
with a
local oscillator, LO. So, no, it isn't sharing an antenna.

Please help me understand how the IF OUT works on an Elecraft
radio. Is
it the same thing as sharing the antenna with a T/R switch, or does it
tap the RF processing chain later down the line. Does the IF OUT merely
share the antenna, or does it come later in the circuit - are there any
practical reasons why one is better than the other? I presume the IF
OUT is better, but wonder why.
[It matters and will settle a bet who eats steak and who eats hot dog.]
Thanks in advance K8JHR
