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.

Thanks in advance K8JHR
