Fake it just moves the A VFO before transmit (if needed) and back for receive.
The delays seem just a problematic.

I saw the same thing when I had it set to split. I'll have to admit
though that my rig is an IC-7000, not a K3 (yet).
Changed over to "fake it" for the split operation setting, and it
seems to do better, with faster xmits.

I've made a few QSOs with FT8 but have had less then stellar success. In
looking for possibly causes I took a close look at timing, since a lot of
the chatter in the WSJT Yahoo group is about the need for close time
synchronization.
I noted that when my transmit interval occurred, there seemed to be about a
one and a half second delay before the K3 began to transmit. I began an
exchange of email with Bill, G4WJS, about this issue. I quote from one of
his:
"If you are seeing a 1.5s delay then that is because CAT commands sent
before PTT, even if PTT is "virtual" due to using VOX, are taking
roughly that long. The K3 series is problematic in that certain CAT
commands can take a long time to complete, these are mostly mode change
related, even if the mode does not actually change, as a DSP reset that
takes 0.5s or so has to be completed before the CAT command returns
success. I suggest setting "Settings->Radio->Mode" to "None" and setting
the rig to USB-DATA-A sub-mode manually on both VFOs, as a test to see
if things speed up for you."
I tried his suggestion and didn't see much change, then I decided to turn
off Split in the program. This reduced the apparent delay to <0.5 second. I
say apparent because these are eyeball measurements, best made by looking at
the clock display while listening for the TX audio to drop out. The message
is 12.6 seconds long so if it ends at or around 13 seconds I would guess
good enough.
Anyone else see any of this?
Wes, N7WS
