Don't forget that KX3 is QRP radio for portable operation. I tried hard to
hear an image in KX3, and could not.

It appears that the kx3 does not have dynamic image rejection, rather a one
time calibration for image rejection. Has there been any talk of the KX3
implementing dynamic image rejection? Perhaps a future SW revision where the
image rejection goes to > 90 dB. The Flex products implemented dynamic i
Yes, if you are running a panadapter fed from the KX3 RX I/Q output, and you
enable 8kHz shift, then all the signals are shifted up on the panadapter
display by 8kHz.
Further, if you enable dual watch, then the main signal from VFO A remains at
centre frequency, and VFO B is plus or minus 15 kH
If operating CW, another approach that could be used to avoid a strong signal
in the
opposite sideband is to hold the MODE button to go into CW REV.

So if you are running an panadapter and turn on RX shift then what happens to
the panadapter display? Are the frequencies shifted on the display by 8 KHz?
The Sherwood data would indicate to me that using the 8 KHz shift is a good
thing to do all the time if you do not have the roofing filter and s
Thanks Don. I was distracted by Matt Z's comments, and forgot to treat the

Let me try to help a bit.
On the roofing filter/8 kHz shift, you have the cart before the horse.
The 8 kHz shift requires that the roofing filter be bypassed. There are
other cases where the roofing filter may be bypassed without the 8 kHz
shift. For instance Dual Watch being active.

"At 1 kHz performance is opposite sideband rejection limited. On CW consider
switching to 8-kHz IF. Note: Roofing filter disabled in this mode."
I do not see anything in the manual about the 8 Khz IF mode.
