Well, MFJ is MFJ but Elecraft is Elecraft. I doubt very much that any MFJ

A 2.8 KHz filter is not appropriate for for AM
So true
If you want to operate diversity in AM you will need one of the wider
filters.
I don't and don't recall mentioning I did want to. I do recall stating I
found this behavior accidentally.
I really wasn't expecting such a debate
Waiting for Wayne to comment sounds like a stellar idea! So say we all?

I don't know where others might come from, but for me running sound stage
diversity implies two IDENTICAL receivers each being fed to one ear.
Assigning a requirement that that all should behave normally when the
receivers are NOT identical seems unfair among other things.

I am going to go 'out on a limb' and make a wild guess that it did *not*
behave that way with the old synth boards. Wayne will likely correct me
if I am wrong.
With the old synths in diversity mode, there was one synth driving the
main RX and the other driving the subRX.

Peter,
Turn on SPLIT - you will see that the little TX arrow to the right of
the display now points to VFO B (It was pointing at A before engaging
SPLIT).
That arrow tells you which VFO will be used for transmit.
Turn the VFO B knob to the frequency you want to use for transmit.
If you have

Which version of the KXV3 is installed?
Check D1, D5 on the KXV3 Main board and D1 on the connector

A 2.8 KHz filter is not appropriate for for AM as it will
limit the maximum audio frequency to 1400 Hz (carrier +/-
filter bandwidth). If you want to operate diversity in
AM you will need one of the wider filters.
If you're not in AM, keep the bandwidth below 2.8 KHz and
there will be

If the filter offsets aren't matched, in diversity mode, the firmware has to
set up the main/sub synths differently rather than drive both receivers from
the main synth. This is supposed to be working, but there could be edge cases
not covered yet. I'm looking into that.

I'm seeing a odd problem working digital today with my KX3. Sometimes
when I go into transmit (power set at 5W) JT65_HF, my Signalink shows
PTT active (red light) , the KX3 shows PTT active (red light) but no
power is being radiated. Antenna (dipole) has a near perfect match to
the KX3.

Something tells me I may be your signature edge case for this particular

Rick,
Something on that order is to be expected when you are using different
filters in the main and in the sub. The filter centers do not match,
and that leads to calculations of the filter centers which are different
- the result is that the K3 is 'confused' and the offset is the result.

Not a bug ... the nature of diversity since both receivers
use the main Rx synthesizer (including filter offset).
If you want to use AM and an audio bandwidth greater than
1.4 KHz (filter/2), you will need to add at least one more

Hustler and Outback antennas usually compete for the bottom of the results

See K0BG's website for LOTS of useful mobiling information.
Keep in mind that by far the majority of the radiation from a loaded
antenna occurs between the bottom of the loading coil and the
